FreeCAD for Beginners #2 - Sketching and Constraints
HTML-код
- Опубликовано: 4 июл 2024
- We will create a fully constrained sketch and model it. We will discuss the details of how to create a FreeCAD sketch from a drawing and apply constraints in a logical way to make constraining even the most complex shapes easy. We also download the latest stable release of FreeCAD 0.19.1
NOTE: My mouse settings are set up as "blender" down on the right hand side of the FreeCAD window. If yours are set on something else, your mouse will move things in a different way.

My uncle gifted me a 3D printer three years ago, but I've been procrastinating on learning any CAD software. Now, I'm determined to start watching your video tutorials, and I've discovered that the FreeCAD community on Facebook is very supportive.
Excellent, yes the whole community is very supportive.
Watching this in 2023. Very underrated channel. I'm gonna share this for more exposure! ❤❤❤
Thanks!
Five minutes in and I like they way you teach. I was trained in several different Cad systems and used AutoCad and SolidWorks for years. I'm retired and am starting to use FreeCad and I thnkyvrymch...
You are very welcome, thanks for the feedback.
You are showing me a whole new way to think about an object. Normally I would think about the dimensions first but now I see that relationships can be as important.
Thanks for the feedback.
Very useful. After viewing just a few of your videos I was able to create several 3D prints I needed.
Fantastic! Gland I could help.
At last someone who speaks plain english on how to use this program. I have struggled with other RUclips "courses" who all fall into the trap of assuming you know too much when you are just starting out. WELL DONE....a fantastic series. Thank you.,
Thanks for the feedback!
Sweet! You explain as you go!
I try to. It definitely makes it easier to follow.
Very nice tutorial. Explained the steps very thoroughly. Thanks
You are welcome 😉
Thank you for this content, well presented, good pace. The world needs more folks like you!
Thanks Daniel
Great video for beginners. I'm enjoying your teaching style. Totally new to FreeCAD here and looking forward to going through your series on FreeCAD. TYVM!
I am glad you are enjoying it. I am working on part 5 of the beginners but don't be afraid to try some of the other stuff too. Especially if you have a 3D printer or cnc router.
Iv'e looked at at least 20 of these tutorials in regards to making a special bracket for my 3D printer, none of them I can fully understand and all way to fast in interpretation. Your Tutorial is by far the best and easiest to follow and understand by far. I will be following your lessons from now on. A big thank you Sir
Glad I could help!
Pitched at a perfect level, thanks.
Thanks for the feedback
Very helpful. Many thanks.
Glad to hear Peter
WELL DONE! you are an asset and a blessing to this community.
Thank you kindly!
Great tutorial. Thank you.
You are welcome
Just getting to know FreeCAD myself and have to say this was good stuff. Very easy to follow. Much appreciated for your videos.
You are welcome
Great video, thank you!
You are welcome 😎
slowly but surely the fog is lifting and results are happening. Thank you very much for allowing me to use your time for my benefit. really well presented and paced
You are very welcome, glad you are enjoying it.
Great video, thanks for sharing, will be checking out all other vids. Very informative
Glad it was helpful!
This is the best FreeCad tutorial on RUclips. Thank you
Thanks, make sure you share it.
VERY CLEAR EXPLANATIONS!! I liked, subscribed and expect to go through ALL of your FreeCAD for Beginners series. Thank you for your excellent content!
Thanks, I appreciate the feedback
Thank you so much for this tutorial. I’ve tried several and just got confused. Came across yours and am very happy with the way you instruct. You removed the frustration I was feeling with the others. I’ve just completed the second lesson and anxious to do more because I feel I’m getting it. Thanks again.
That's great to hear!
Great tutorial, thanks a lot. I've tried several RUclips beginner tutorials for FreeCad and I've had the most success with yours. On to lesson #3!!
That's great to hear.
Well done. I like how you explain what you are doing and why without going on wild tangents.
Thanks!
Thank you very much for the work you have put into this course. I really appreciate it. It has been a great help, to learning freecad :-)
You are welcome
Thank you for letting me see this video.
You are welcome!
Great video. I am going to try to apply what I have learned in my drawing.
Wonderful!
You are doing a great job for the beginner friend, have a nice day !!!.
Thanks Brian
Very nice tutorial, thanks
Thanks for the feedback
Thanks for this I have been teaching myself but it is trial and error. This taught me lot so I will be watching more. Have a great Christmas.
Thanks Robert, I am glad the videos are helpful. - Enjoy your Christmas too!
Thank You!
You are welcome
great video keep them coming
Thanks, will do!
Very useful and clear
Thank you
great stuff
Thanks James
I like it. you are doing a very good delivery of interesting information
I appreciate that!
you have a great teaching style! i tried at FreeCAD a long time ago and dropped. you give me spirit to learn and the faith that i can do it!
Thanks, I appreciate that.
Had a few issues and some confusion however found it helpful to scroll through the comments as others had the same issues and offered up the fix. All good, on to lesson 3.
Excellent, just be aware that the earlier videos are on earlier versions so there may be slight differences.
Fantastic thanks
Thanks! 😊
thanks a lot!
You're welcome!
I've only done a small amount of CAD and I'm new to free cad but i think your videos are some of the best on RUclips
Thanks, I really appreciate the feedback.
okay, first.. well done.. really WELL DONE! I have learned more about using FREECAD in your first 2 videos than watching a dozen others..
Thanks, there are loads more to watch.
@@Adventuresincreation I am.. trying to work on a cylinder that has sloped top ( at an angle ) .. So looking forward to figuring out how to do that.
@@charlesdix4831 it depends how it's sloped but either way it's possible.
This video, as well as your whole series so far, have been extremely helpful for me. By way of a tad of feedback, I somehow got hung up when it became time to put in dimensions, as 1/2 of my sketch tools were blued-out. Turns out I had to click on the red/blue box icon and enable non-driving parameters or some such and then I could again follow your tutorial perfectly. No idea how I did that to myself, but maybe that will help someone else. Again, great series. Thanks.
Usually if you have to make them non driving dimensions, you have somehow over constrained the sketch.
This was very helpful. Nice that you showed us the pencil sketch first so we knew where we were going.
An explanation of what is a "Part" and what is a "Body" would help. I am sure I do not yet understand.
Thanks for the feedback
Ditto. Your series is excellent and really helping me, but I too could use that same clarification.
@@MotosAndMachines I'll add something in the next video.
Thank you very much from ItalY. Very good session. I've tried to make it a little different by starting from a rectangle and then i removed the other material
There are definitely many ways to achieve the same end goal. It's best to do what works for you.
It was a good explanation, thanks. I got an orange scketch 2 times, and it said I had unnecessary constraints.
Sometimes you can "over constrain" a sketch and it will let you know that. I always try to approach it by constraining geometry first then dimensions.
@@Adventuresincreation i got that many times... selected it and deleted it ... :)...
Really thanks for tutorial... it was really helpfull
I'm starting out in CAD and your explanations for FREECAD are excellent and detailed. I hope you will continue the teachings. Congratulations!
I intend to continue. I am working on the latest video now.
A very clear and easy to follow tutorial - thanks.
For those following along, if your sketch turns red it's because you've created redundant constraints. If you look in the "Tasks" box at "Solver Messages", it will list any redundant constraints - you can either delete them manually or check the option "Auto remove redundants".
Thanks
thank you for your videos
You are welcome 😉
I did have some trouble following step by step and ran in to to many constraints.
Thank you, got this lesson done, but my constraints where different from the video, and it was fully constrained.
There is definitely more than one way to constrain sketches. I usually work on geometric constraints before dimensional ones. Just my preference.
nice thanks
You are welcome
Great tutorials! Just wondering if you show how to create rounded ends in the sketcher?
In later videos you will see that.
Great. Greetings from Germany.
Thanks! Where in Germany?
@@Adventuresincreation Kempten (Bavaria)
@@rudolfowalchonzo2356 love it!
@@Adventuresincreation where you are from?
@@rudolfowalchonzo2356 I live in FL but I am originally from England.
Had the same problem: sketch turning orange, comment said "invalid sketch". Looking into the options, orange color is used for an invalid sketch, According to FreeCAD wiki, this is usually because the sketch is over constrained. Solution: while in the active sketch go to "menu>sketch>sketch tools>select redundant constraints". the sketch will show all redundant constraints. Now press "delete" en the problem is fixed. I'm using version 0.20.2 and my GUI is in Dutch, so it might be the text in the English version is slightly different from what I wrote above, but this is what it is about. According to the wiki, their is also a button "validate sketch", which might also solve the problem, but thus far I haven't found this button, my GUI is somewhat different from the one used in this movie
Check the box that says auto remove redundant constraints
Thank you. I had the same issue. You gave me the solution
Thank you very much, I have over the last few months enjoyed the toturials, I have especially looked for something about how the Tree works, what to take care of not doing and doing it in the right order, I have drawn a lot and deleted a lot , since I can not get the parts apart without messing it all up, a dream toturial for me, would be to draw a simple part, and make a top and a bottom from the surface of the 1st part, a mold / mold .
I actually gave up the project with Freecad 19.0 and drew it in Vcarve pro as "layer cake" slices ((glued together)), or whatever you call it overthere;) I could also do it by hand without a PC, but thought it was more fun to draw it first in a cad program, but is freecad the right thing to draw mold in?
thank you very much
Regards JJ DK (Hobbyonly)
This is in intriguing as I was a tool maker, making injection mould tools. I will put some time into this.
Thanks I’m switching from fusion 360 to freecad
Excellent, I did the same, check out my video that discusses it with tips to get you switched over
Noob here, I noticed with zooming using the scroll wheel (btw, thanks for telling me about SHIFT! :) I found you can zoom in and out based on the location of the mouse pointer.
One thing to note on that Jeff, in the bottom right you can see a "mouse" setting, it lets your mouse emulate certain other software "mouse clicks" I use "blender" as I am a blender fan too. - You may have your mouse set on something different to me and so your mouse wheel may do different things.
@@Adventuresincreation Yep, switched..but I just was making this comment since I noticed I had to fight to zoom in to items...to find it was due to the mouse location on the screen. :)
I'm glad you mentioned that. I hadn't noticed, but it's very helpful, and now I'm doing a lot less dragging to recenter after zooms. Thanks.
Thank you for the informative video! Could you also cover 2D modelling in FreeCAD?
What do you mean by 2D modeling?
Good Day, Just started watching your video's and subscribed. I will be watching all your beginner video's to start with then progress from there. What I am really wanting to learn once I get the basics is how to draw house plans both in 2D and 3D, as I used to be a builder and worked as a site manager for a building company here in Australia before I retired. I have always loved drawing and have used AutoCAD Architectural as well as Fusion 360 and SketchUp, and I came across this program which I think will cover everything the other programs do. I also touched on Revit for a while.
Have you thought of doing any video's on the concepts of house plans and the structures as I am sure you will get a lot of people interested in this. Just a thought as I said love your videos. Cheers Regards Kim. Thankyou.
Thanks for the feedback, I have not done any architectural drawings. I have just done a tech draw overview for my patrons and channel members. I will be creating a public version of that in the near future.
Anyone know how to show the constraint coordinates? I'm using FreeCAD 0.20 and the Constraints box does not show the options for "Hide Internal Alignment" and "Extended Information". Don't know if it's a preference setting but if it is I haven't been able to find it. TIA to anyone that can help.
Did you ever solve this issue?
@@Adventuresincreation Nope, I figured maybe it was a UI change due to version change and gave up. Looked like it was a handy feature though.
I have my constrained flat fish completed successfully. :-)
Very cool, I can see how this works so far. Thank-you.
My only complaint is that you sometimes confused vertical and horizontal when describing which you were creating. Visually you were correct, just the verbal description.
Thanks Craig, glad you were able to get your "fish" constrained. When you say, confused vertical and horizontal, are you talking about dimensions?
@@Adventuresincreation Oops, yes, that was what I meant. A couple of times I was using keyboard shortcuts to set constraints while listening to what you said and had to back up and do what you meant. Not a major.
Hi absolutely fantastic video and thank you for sharing!!!! Can I ask you when you made the fish tail (dovetail) can you pick the degree you want or are you stuck with what freecad decides for you thanks again
You can adjust everything
@@Adventuresincreation that fantastic news I’ll be downloading ASAP and I forgot forgot to mention new sub here 😂
How do you get the graph on the screen?
I'd you go into the draft workbench it will show up, you can toggle it from there.
Hi, thanks for the best tutorial I have found so far. I am a 76 yo learning new tricks for my recently built DIY CNC and my first play with CNC machines and 3d modelling, although I have a lot of experience with 2D drafting CAD. Everything went fine with the tutorial right up to a fully constrained sketch all green. When I click close I do not get the menu to pad the sketch. Not getting the same menus as you has happened a number of times thru the tutorial but I have been able to overcome it, but not this time. Also when I click close I now have two sketches "sketch" which seems to be the correct constrained sketch AND "sketch 001" which does not seem complete when I highlight it. Any help gratefully appreciated. Kind Regards ..... Mike, Tasmania, Australia
Hi Mike, it sounds like you may have accidentally created sketch001. No worries, you just delete it. Then, highlight your sketch in the model tree and click on pad from the menu bar. It should work for you.
BTW, your toolbars are set up differently from the default toolbars. It makes it a bit harder to do exactly as you do in the videos. Next time you might want to start with an exact clean setup and show the students how to set up the toolbar like yours.
Good video.
Good idea, thanks
@@Adventuresincreation I turns out that you adjusted your menus and thus showed your audience how to do this in video #3.
Great video. Im having trouble with the step at 16:44. I've started from scratch twice and whenni click on the two corners and the line then symetrical the entire drawing turns red.
Also while i saved the drawing when I tried to reopen it was totally a mess.
Any help would be appreciated. I will give it another shot tomorrow. Perhaps ifbi watch on my tablet instead of my phone I'll see what I'm missing.
It sounds like there is something wrong with file did you try a completely new file? Does it turn orange?
@@Adventuresincreation Found the solution and now I see it in other comments. I did not have Auto Remove redundant and Auto Update checked. 😖 Thx
I cannot get the part to be symmetrical about the Y axis. If I try it as you demonstrate, all the construction lines turn red.
Do you have auto remove constraints checked?
Could you tell me if you have done a freecad tutorial on Threads. I have looked but didn't find any. many thanks Mike
I have not done one on threads yet. I will in the future. I use the fastener workbench.
@@Adventuresincreation Thank you.
PS> My version of FreeCAD is 0.21.0 which I downloaded from the FreeCAD website. Is it a "stable version" as it is different in a number of ways from your v19. For instance the preferences menu is very different. As I intend watching the rest of your tutorials would it be better for me the download version 19? Regards Mike, Tasmania
I am using version 0.21 now too. These videos were created before it was available. Let me know if you get stuck
All OK, I am not sure what I did, thanks.
Great 👍
Part and Body have the same icon except the different color. Why is that so? What exactly are these things?
A part is a container for multiple bodies.
very nice... back in April i installed freecad-19 and it works nice, however, freecad-18 now goes to starts-up mode then nothing...Mmmm...??? thanks...:)
The 0.19 installation probably changed some of the core file versions.
@@Adventuresincreation thank you...:)
I have tried copying what you are doing maybe 6 or 8 times. No luck - it turns orange and stops working.
Can you share your file?
I have the same problem, I wonder if it’s a bug in the latest version 0.20.2
At 16:41, trying to create symmetry and select the 2 points then the x axis and symmetry and everything turns red, why?
If I had to guess, it's most likely that you had something else selected before you selected the points for symmetry. Try deselecting everything by clicking away from the sketch. Then carefully select the two points and the line and then click symmetry. If that doesn't work, share the file with me and I will take a look at it.
@@Adventuresincreation how do I share the file with you? I bring up your video on my phone then cast to my TV , while creating the actual project from my laptop? Thanks i did delete the first project and file and started from scratch, then it did it again. Ugh
Thx
@@garyweliver1870 I sent you the file back with the symmetry applied. Well done on creating the sketch.
Not you. I have had the same problem, tried everything. Even with just a rectangle the symmetry just turns everything orange
How come all version fo FreeCAD start with 0. Why is there no version 1.0 inspite of this program being out there for more than 20 years?
That is their versioning system.
Hi - when making the horizontal lines equal on the little square my sketch turns orange. What am I doing wrong? I want to thank videos the best and easy to follow along with you, I have tried other videos that I was lost in the first 5 minutes with you videos i actually feel that I can learn this at 68 years old. Thank you! Bob
Thanks! That normally means it's over constrained. Do you have the auto delete redundant constraints checked?
@@Adventuresincreation Thanks for replying... Where would I check to see if the auto delete to see if it is checked?
@@bobkarstien1248 In the sketcher task pane.
@@Adventuresincreation II want to thank you for all your help! I am using version 21.2 I retried this lesson 3 times and I am getting different results then you on somethings I did not think there would be that much difference between the versions. Should I see if I can find the version you are using and remove 21.2 version? Thank you!
@@bobkarstien1248 No, don't remove that version, let me know what you are having trouble with and I will make a video to show you if there are differences in 0.21
Per Mark below, I like the way you teach as well. I only have one irritation. I'm working on RPi, and 0.18 is running great. I don't want to run 0.19 and didn't want to the first time around? Why are we starting this vid, with downloading FreeCad again as opposed to referring any newb, to the first vid in the series and downloading, etc....? Not complaining, in fact I'm in your debt as you chose to take this work and post it. Just making the observation. Thank you.
The latest realeaa is much better
Adventures in creation LOL, yes but I’m tired, running 64 bit ARM on RPI and don’t EVEN know how to upgrade considering I loaded the first version with sudo apt get install... Get my point? I’m sure I’ll upgrade at some point but, it’s not as easy as just CLICKING SOMETHING to get it done on this puppy. Am I a masochist for choosing this platform? Yes, yes I am lol... I just want to freecad some stuff and 3d print it. Not sure around endlessly updating libraries and finding out that the version of OS and hardware I have can’t run that yet? :-) All is good, Namaste, carry on. I’m crashing. Lol...
I have it on Ubuntu Linux too. You don't have to use the apt version you can download and install it manually if you prefer. However apt should take care of all the dependencies.
what to do if it says redundant constraints ?
You can auto remove them by checking the box
@@Adventuresincreation while making points symmetrical is it possible the points where already symmetrical so it says redundant constraints ?☺
whenever i try and constraint two points my model turns red
Hi Justin, is it saying it's over constrained?
Me too. I can't get past this part of the demo
Did it automatically make a hole for the eye?
If the sketch has a hole in it, then the pad will have a hole in it. Does that answer your question?
@@Adventuresincreation So that square was automatically a hole when you made it because it was on top of the original part right?
@@mrs.dillenbeck5841 yes, if you create a shape inside the face of a sketch it will become a through hole.
@@Adventuresincreation That answers my question. Thank you very much, I appreciate your series on the topic. Take care .
Had the same problem has others. I get to the the symmetry part, select the three points then enter and the whole sketch turns orange?? Very frustrating any solution?
My version is the latest….0.20.2
Can you share your file with me?
@@Adventuresincreation Thanks for getting back. I opened a new file and placed just a rectangle (only) tried symmetry constraint on both the vertical and the horizontal, the rectangle turns orange and does not constrain symmetrically. If l constrain diagonally selecting the the three points it constrains equally into a square as expected. I guess it could be a bug in the latest version? Frustrating seeing you have no problem in version 0.19. I note many of your viewers having the same problem. I’m going to attempt your electrical box next, hope there are not symmetrical constraints in that one?
@@brianwaites4572 I just did exactly that, it works fine. - I think you may be over constraining somehow. If you just draw a simple rectangle and constrain symmetrically it will work. Take a look at the panel on the left where it tells you how many degrees of freedom you have, this will help you, if it's over constraining it will tell you that.
@@Adventuresincreation Thank you, I did exactly what you did by placing a simple rectangle and it still turned everything orange! The DOF turned red and increased. I’m still baffled.
Love it you have a Hue around the pointer.
You are extremely good and SUPER fast with excellent videos. Here are some tips, hope it help to get more subscribers.
Not all or any might be applicable to your videos at all. Watch your own videos on RUclips and then decide.
Sound, Icons, SMALL Pointer and color.
Newbies need help and some tutoring. There are a lot of people with eye sight not 100%. So some need a reason to stay on your videos.
Some of the following might not be applicable to you.
-- Voice is always better than music or silence. About 60 to 90% better. With voice you can explain and relate to your viewers.
-- 99% of ALL Pointers are normally TO small and black or white. Causing them hard to follow and disappearing at times.
We found a LARGER pointer in RED and if possible a YELLOW hue around it is ideal for bad eye sight .
For Windows:- catnip5.itch.io/mouse-highlight
For Linux:- Download www.google.com/search?channel=fs&client=ubuntu&q=Tweak+tools.
Then if using Ubuntu Open - Settings --> Accessibility and there is more tweaks. Zoom "might" make the pointer jerky on some computers.
-- The icon bar icons are usually small, your viewers can not see what you are selecting, minimum size should be at least 24 AND/OR bigger.
-- The Constrains when in red are hard to see for people with bad eye sight and mostly unreadable in videos. Change it to black and all will be able to see and read it.
We hope some of this is useful to you.
Thanks for the tips. I appreciate your input.
How do I get the 'graph paper' effect-? Looked under the VIEW tab...?
If you go into the Draft workbench you can toggle the grid on and off.
@@Adventuresincreation Thank You-! And Thank You so much for producing these videos, You're the only one who knows how to make video's where #1. I can hear and understand what you're saying and without all the hoopla (is that a real word) I need to look that up. Thanx again.
