FreeCAD Modeling a Masking Tape Holder using parametric design.
HTML-код
- Опубликовано: 5 окт 2024
- In this video we will go through the process of creating a part suitable for 3D printing. The details of how we model this part and finally show it in an assembly. The part is from a masking tape holder that I had previously designed in Fusion 360 and published on Thingiverse here www.thingivers...
Also in the video I show my start up macro it is available here:

I was looking for something to watch during lunch and it seems the other day I was wondering how to make a circular slot. Thank you for all the time it took to make this.

You are welcome
I've been using Fusion 360 for a while but was never happy not being in control of my own files. Today is my first try at FreeCAD and this video was a great first step. Am now watching your video of "5 Tips for migrating...". Thanks a lot for your videos and macros Ian.
Thanks Justin. I am glad you are giving it a go. I haven't found much that I would need fusion 360 for. Don't get me wrong, it's a great piece of software that I spent many hours learning but, I was greatly disappointed when they changed the licensing. It put up a red flag 🚩 that sometine in the future it will no longer be freely available. Plus, FreeCAD is definitely coming along in leaps and bounds. I definitely recommend version 0.19 for general use. I have been using it exclusively.
Hey, this tutorial is awesome. Specially good for new people. Thanks.
I see only one small issue. You've told: When you have a piece that you like, save it. NO! Save things every single change. It is a computer. It will do it. It is just a ctrl+ or cmd+s.
Ah, you got me. "save a lot" I should have said 😉
@@Adventuresincreation haha
Automatic continuous saving with infinite undo is the way to go...
...mind blown, I'm trying to follow step by step.. this was great. thank you
Thanks for the feedback. You are very welcome!
Thank you for making such cool and interesting videos! Thumbs up!
Thanks for the feedback!
Again I have to say this was a very good tutorial :)
I was fascinated to see how all the shaping proesses ran together.
- sketch 1: the revolve of sketch 1 I would never have known to do.
- sketch 2: I would never have known to put a square outer around sketch 2 to achieve the three pronged pocket, followed by the wizard like sketch shift by z=-4.05mm to leave an uncut base.
- sketch 3: the 5mm diameter hole cut through the centre of the base with the radiused cut out arrayed around the edge using the polar array button, was very interesting too see too, as was,
- sketch 4: the again polar arrayed cut-out in each of the three prongs, on the vertical axis. I almost missed the vertical axis bit.
The 4mm chamfer at the top was a very nice touch.
I made a file copy after I had followed the tutorial and did it all again, three times, just to get a better feel for the thought processes in shaping this piece. In my file copy I deleted everything leaving just the 4 sketches and the spreadsheet with it's alises, speeding up focus on the shaping process.
It would be nice to see how the masking tape holder was shaped, to get more insights ;)
Again, very nice tutorial :) thanks
Thanks for the feedback. I am glad it helped. I am happy to show how I created the holder in a future video.
Well done. The perfect project for this weekend. Happy New Year to you.
Thanks, you too!
EXCELLENT TUTURIAL!! Would love to see you making a Planetary Gear using Parameters. Where you have it animated. You make this tool very user friend to use.
I am glad you enjoyed it.
Awesome Tutorial!! 👍🏻👍🏻👍🏻👍🏻👍🏻
Thanks, I appreciate your feedback
Really enjoyed the tutorial, especially the macros, I will definitely install those. I think you could have commited to the parametric part a bit more, for example the slot through the arms could have been tape_thickness - wall_thickness - some offset. But you showed me that you could offset sketches, for which I used datum planes in the past. That makes a lot of things easier.
Thanks for the feedback. Take a look at the next video, the electronics enclosure, it is completely parametric including the lid on the following video. I find that sometines it makes sense to go all out on the spreadsheet driven dimensions, sometimes not so much, especially if I don't intend to change certain parts. Your mileage may vary. I am glad you enjoyed the video.
@@Adventuresincreation Thanks, I'll watch it. I totally get the last part. As a software developer I often get stuck trying to do things properly, so I just started doing them anyways because they probably won't get changed anyways.
@@pascal-t have you created any python macros for FreeCAD? I am working on macro but having some issues trying to copy edges in a sketch.
Just an awesome tutorial! Thanks!
You are welcome
Like others, this is a great project to sharpen up one's skills as being new to FC. I have .19, and really starting to enjoy & learn. I cheat,,use a lap top to watch thevid, and larger PC screen to go through the steps. find this better than making hand notes,,Cheers, great tutorials, and this tape hold fits my learning curve. I am now going to start use the spread sheet to enter in data off hand sketches,,thx, Bear
Sounds like a great approach. I don't consider it cheating, more using your smarts 😉
I was skipping though looking for the bits I was interested in and happened to see the offset sketch technique (16:30). Why did this never occur to me before? I've been creating datum planes (that's fine and useful, but redundant for things like this) or sketching on a surface (tends to break in some circumstances).
The offset sketch is truly a useful technique, sometimes the datum planes/points/lines are useful too. The topological naming issue makes sketching on a surface risky but you can do it if you know you are not going to radically change your model. I believe the issue may be resolved in the future but not yet in 0.19.
Tried to find some tutorials on creating a snap lid but could not find one using FreeCAD. I see the button you show at the end is a snap fit. Can you show how to create a snap lid?
Great idea, I actually did some testing on snap fits and came up with some nice designs
Where can i find the macro to add references in the slpeadsheet. You mentioned that, but I can Not See ist in your GitHub.
It's not my macro, just Google easy alias for freecad and you will find it.
Wow this is big ! I need to get another monitor set up on deck to follow along more efficiently. Opening and nesting videos back and forth is very inefficient ( I don't know how to install that spreadsheet macro (
Are you talking about the macro "easy alias"? You can install it from within freecad itself using the same manager that you add workbenches with.
@@Adventuresincreation install/update selected..all I had to click . I get scared to click. To many train wrecks in my life lol Im old. God bless .Thank you !
@@BrainDeadEngineering I completely understand. I just had to "reset" my laptop back to factory settings because stuff just slowed me down way too much. - I too am cautious on clicking ;-)
@@AdventuresincreationI I feel your pain! This semiconductor life we are trapped is a real pain in ass some day omg lol. If any one reads this in join in on donate to this man. He may make a video of how to sketch on a surface / plane with a angle component attached to it .hehehe. Like say a flat plate with a angle pipe coming from it etc :-) FC angulation vids are illusive. I start bid with a $20
v nice tutorial, thank you :) I followed along and completed the design. Couldn't find the aliases macro on your bitbucket, unless I missed it. I set up the aliases for the B column in the spreadsheet manually anyway.
The easy alias is available in the add on manager. I didn't write it, I just use it 😉
@@Adventuresincreation I did download "easy alias" macro from the add on manager. I'm running the most up to date 0.19 appimage. I selected the rows, 5 or so rows, in column B and ran the macro. Nothing happened. I also tried selecting the cells with values for columns A and B, that did not work either, so I just made each cell in column B an alias manually. I'm running arch linux with the latest Python2.7 (think it's 2.7) and Python3.9.1. (I don't know that much about code)
@@ksmith7122 when you use easy alias just select the spreadsheet in the model tree, then column a (the names) and run the macro it will associate the name with the cell in column b
@@Adventuresincreation thank you. I missed that detail. It was there in the video, I just missed it. It does work. Appreciated, cheers :)
I am just started to use Freecad today, please show me how do you set the dimensions arrow and text to orange colour. Thanks.
The dimensions turn orange when you reference a value from a spreadsheet. If you look closely you will see that the ones that are orange like that. In the next video I will be doing more of that.
Do people use multiple spreadsheets in one project often? Why do you have to name the spreadsheet before the variables every time? It makes the expression unreadable.
You don't have to rename the spreadsheet however if you open multiple files all with a spreadsheet named spreadsheet attached you could run into trouble. You can make the spreadsheet something short.
this is broken if you want to use imperial units. you must specify 'in' at the end of each value in the spreadsheet. Freecad is NOT unit agnostic, internally its treating everything as mm, regardless of what your units presets are
Good point, I always use mm by default. - If you are using imperial measurement you do need to specify that.
To quote the Wikipedia article because I'm lazy though...
Standards for the exact length of an inch have varied in the past, but since the adoption of the international yard during the 1950s and 1960s it has been based on the metric system and defined as exactly 25.4 mm.
The reason I posted this to illustrate that inches are actually based on millimeters by international standard. I live in America but freecad is not broken in that respect.
@@theMikeChastain the point you missed is that if you don’t specify “in” after your units, it will get treated as mm, regardless of what you have your default units set to…
