HTML-код
- Опубликовано: 30 июн 2022
- In this lesson we will learn how to import SVG files into FreeCAD and use the in the Part Workbench to create extrusions. We will introduce some basic boolean operations which we will expand on in future lessons.
The beginners course to FreeCAD 0.20. teaches the fundamentals of freeCAD understanding the basics but delivered in practical examples and teaching you different workflows.
The file within for the box come from 3axis.co/laser-cut-playing-ca.... The file is a corel draw cdr file which can be converted using online tools such as cloudconvert.com/cdr-to-svg.

The best freecad tutorials I've ever found. I never comment on anything but sir I must admit. Very nice work. I can only imagine how much work it is to publish such great content.
Thank you so much. Yes a lot of work and love goes into these as I had a rough time learning the software when there was virtually no documentation. So I am trying to make it as easy as possible for others :). Glad you are enjoying :)
Thanks for remaining faithful to Freecad, instructing clearly and taking us through the steps slowly.
Thanks it's been and still is a pleasure. I have a love for all things 3D but freecad is my main one. I couldn't of done this without the support from all of you taking time out to comment after watching the videos.
These tutorials are overwhelmingly good, you enabled me to model a complex prototype in 4 days of immersion without having ever touched any CAD before. I am so grateful for this series!
It's been a pleasure to share the knowledge and get people like yourself up and running with CAD. Thank you so much for the kind comment. Great to hear :)
This is a really great series. Well done!
Thank you 😁😁😁
Thank you for keeping the work-flow theme in your videos. I haven't had the time to keep up with your videos but they are really well done.
Much appreciated, Thank you. Cheers
oh!!! the possibilities with this. great!
Picking up so much useful information every video! Thanks!
Nice to hear your finding them useful, thank you 👍😁
That one jumped rather abruptly to the next topic but learnt loads again 😀
At about 15:45 in the video, rather than transforming I changed the extrusion distance from 3mm to -3mm. Worked a treat and saved some time.
Just got up to that part and thought the same thing! ^_^
I have a new iMac M1 with 16gb of RAM and although I could get V0.20 installed and to work, sort of, it was VERY unstable. I reinstalled V0.19 which works fine apart from the curves workbench which is very hit or miss. I mainly use Fusion 360 now. The emboss feature is brilliant.
The normal direction for a face is determined by the order of the points.
A face that is drawn counter clockwise will extrude towards you, a clockwise order will extrude away from you.
I think mesh modeling is much more powerful in Blender, but I'm still new to Free-cad and this will definitely help me to bring in my mesh to free cad, then I can export step files, which blender doesn't do yet.
I came from fusion and at the start it's a little bit confuse, but since I start viewing these videos everything is very easy, and I will not return to fusion, thank and a job very well done.
Great to hear, thank you and glad to hear these videos are helping.
Okay, I’ve got the extrude done and can move it with Transform, but how does one change the dimensions of the extruded part (other than the actual extrusion, of course)? Going to take a look at your other videos where I will hopefully find the answer.
All your tutorials are very clear and helpful. I understand that to download any object from the link that you gave I have to sign up to Microsoft Azure. is this the case ? or there is a sampler way to download the item that you work on in this tutorial??
Hey MJS, great video. Please provide the link the SVG so we can follow along! Couldn't find it on your Patreon like last time.
Well I messed that one up sorry. I have added this to the description of where to get it from and online sources for converting the file. Appologies.
A fascinating series, thank you. Do you have a video on using svg input to create an expanded solid from a series of frames in 2D? Creating a boat shape.
Thank you, so the frames you have are each of the cross sections of the boat? In which direction do they travel.
@@MangoJellySolutions The boat frames are in the x-y plane and are stacked in z separated by various distances.
@@brianwharton9385 It depends on your svg's and what they look like. If they all have the same amount of edges in the drawings then you will be able to create a loft through each of the sections just by selecting them and adding them as you would do a sketch similar to as I have done in this tutorial ruclips.net/video/ToobD6C4x9g/видео.html .
@@MangoJellySolutions Many thanks for the video, it explains quite a few things I was struggling with. I'll use the SVGs as masks to create the shapes on each station using Bsplines with the same number of nodes. The deck has a step in the profile at around half-way but I'll raise another query if I get stuck. Great video, keep them rolling.
Any tips or getting things to render faster after changing, I only just started but it seems fairly slow for my PC specs, I tried scanning through the forums a bit but I figured because you have been using for a while you may know of something
Thanks! I have imported an SVG and was able to extrude the outlines. But when I select two overlapping extrusions, the boolean operations are greyed out. Any idea why? Update: It's because there was a completed action on the (hidden) Task tab that was waiting for OK to be pressed. That is terrible UI, as is the Task tab in general.
Had it made more sense if you created 2-3 figures in Part Design, then got them together or cutting from each other on Part?.
Hello, im new to FreeCad can you tell me for what i should use Part WB because in Part i can Boolean objects together but everything is not with fix distances and sizes so for what i or you can use the part WB ?
Thanks for these tutorials. They are certainly helping me learn FreeCAD but I'd like to find some other resources to help me learn more quickly. Are there any online courses you can recommend? Or any books (there is a book called 'FreeCAD 0.20 - A Power Guide for Beginners & Intermediate Users' by CADArtifex, have you seen this, can you recommend it?)?
I know FreeCAD is at 0.21 as of 8/2/23, what are the differences between 0.20 and 0.21? Are there any of your videos that may not work as described on 0.21? Will you publish a new set of videos for 0.21 or at least a single video showing any differences and guiding us on anything that may not work (or works differently) on 0.21? I definitely understand the difficulty in keeping things current, especially with the many updates released but a bit of guidance would be helpful if possible.
Appreciate any guidance you can offer. Thanks.
Hi sorry for the late reply. I haven't got any recommendations for books as I always find them very hard to follow and go out of date very quickly. With videos I find you can see the actual steps. I do have a video in my collection regarding some of the additions to 0.21 but the older videos are still valid. The main things that could be an issue is that there is no image workbench anymore. This is now done via the top menu, file, import. And also the sketcher has moved the check boxes for auto constraints and remove redundant constraints in a small drop down in the same section. Hope that helps.
@@MangoJellySolutionsThanks for the reply. Ok.
Another question I have is what would you recommend for example designs to work on? Would like to find a good source of design challenges that one could implement to see how the various methods covered can be applied. Seems like there's always multiple ways to implement anything, so I realize there will very different ways to end up with a valid result. But if you have any recommendations for designs to at least try to implement that would be helpful. Appreciate any info. Thanks.
At 14:00 when box selecting, my program crashes. Even if I don't actually select anything with the tool.
EDIT: I selected everything from the sidebar instead. That got around the issue.
How to, instead of extruding in place, moving the outline of the sketch, to another plane and making a hole with that pattern?
You can use the map mode of the sketch and attach it to another face on that plane. Have a look at my playlist FreeCAD: The basics. I am slowly putting together a number of short ad-hoc videos that focus on one tool or subject. There is one there on sketch attachment. ruclips.net/p/PLWuyJLVUNtc3Fj7rKdhbavwpIA-uGkHXz
I'm having issues with importing SVGs in FreeCAD: I have a polyline object (it's text from a proprietary font, which I don't have access to), but it's imported as a number of connected B-splines instead of one B-spline. As a result (at least, I'm assuming that's the reason) I can extrude it, but any other operation on the extruded part (like thickness or offset) fail. I've tried making a face from the extruded part, or trying to convert it to a sketch and back. but to no avail: still a set of B-splines instead of one big b-spline. Any tips on getting one big B-spline from the SVG? Or will that not even solve my issue?
Try creating a 2D offset of the bspline geometry instead of a 3d offset of the extrude and see if you have better luck. I have been working with these files lately and found better results by offsetting early
@@MangoJellySolutions thanks for the tip. I've been digging into this and realized that freecad is importing a single SVG multi-spline shapes as multiple/separate B-splines. And that's the big problem. I've kinda got it to work by selecting "use old python importer" in the svg import options. Still, the result are not great, not giving correct faces.
Where is the joedq691.svg file? Do you have a link to it?
Hey, John... and anyone else following afterwards... I used duckduckgo, and I found the file joedq691.cdr. That is a Corel Draw file format. I used an online file converter, CDR ~> SVG, and got the desired result when I imported this converted file, joedq691.svg into FreeCAD.
It would have been helpful if MJS provided a link to this file.
@@bicicogito989 I used online-convert ... worked fine without any sign-in or permissions.
I cant get this to work on version. 0.21.2
Hi. I work on 0.20.2 version on Win10. For some reason when I create compound and then extrude it I end up with two extrusions ( Extrude001 and Extrude002) of the same compound (like an extra copy) and I have to remove one ot them from the list. Even without making a compound I end up with two extrusions of the same path. Is this a program glitch or am I doing something wrong? Thank you for doing all this videos. It is a great series and I want to go through all of them :-)
By any chance when you create the extrude do you hit the apply button and then click the ok button. If so, this catches many people out. Just click the ok. The reason why there is an apply is because you can select a different object after you have created the first extrude and extrude the other object without closing down the panel. It still catches me out to today. Glad your enjoying the videos
I get this error when I try to extrude my compounds 18:13. it says "Can't determine normal vector of shape to be extruded. Please use other mode." What do I do?
If you look down on the extrude options before pressing OK you will see a direction which you can select. The reason for this is that a compound contains a number of objects, each can have a normal vector (normally with a 2D object such as a sketch this runs through the object as 2D is only in x and y). When you have groups of objects together there is no normal so it's left up to the user to supply the correct direction x, y or z. Click either and then click again to make it a minus value if you want to extrude in the reverse direction
When i click on edge to be extruded in part workbench, freecad shows a message cannot determine shape of vector and wants me to use another mode!
using V0.20 freecad
same with me, have you got the solution
Any chance i can make a request for a video?
I want to make a mold for the fuselage of a radio controlled glider. I have a normal .stl and want to make a two part mold, with one or two keys for alignment.
Please 🙂
Could you send me a link to the stl via email, you will be able to find out in my about section on my channel.
I couldnt find the SVG file in the linked location, the website looks super sketchy.
can confirm that the website linked is very dicey, taken me 2 days to get rid of malware
I could't find working link to the Laser Cut Playing Card Box Free Vector cdr file. Can you link the the actual file here? The original might have been deleted.
I'm having the same problem, did you got the file?
Never got it@@moryehuda6528
I didnt get it why use part design if you can do more in part
Seems as if FreeCAD 0.21 does things differently when extruding like in 5:55. I get the error "Can't determine normal vector of shape to be extruded. Please use another mode." Just wondering if anyone have a solution to that.
Nevermind. Thats just me being stupid. I Tried to extrude a filled shape.
Just to let you know you can resolve the extrude of a filled shape if you get that error. If you look at the panel to the left there is a directions of extrude. This can be set to the direction of your choice allowing you to extrude and range of different geometry.
I cant import svg files.
I appreciate your tutorials very much but this one is missing two vital aspects pertaining to SVG import. 1. Even after simplifying and combining paths in Inkscape FreeCAD still see them as separate paths. 2. Positioning - both in a plane and as importing to a specific wall on a solid (if possible at all). EDIT: I did all the cutouts in Inkscape (Imagine e.g. windows in a contour of a simplified building facade) and when imported to FreeCAD it's all mashed together, windows not cut but listed as separate paths. EDIT: 3. "Wire is not closed" - how to handle the error when FreeCAD doesn't give the slightest hint as for neither location of "the problem" nor how to fix it.
It's funny you should say that, I have just finished some freelance work regarding svg and freecad and learnt a lot more. So inkscape adds its own custom svg elements depending on what you are doing. You can get around this by exporting the svg out as the file type 'plain svg'. Another issue is layers. With svg it's essential to remove all layers before exporting into freecad.
Onto the wire not closed issue, it can be resolved in the sketcher workbench, select the sketch and validate sketch. This will give you a set of checks to run which can identify the issues. This video could help ruclips.net/video/w7_jCxxN1OY/видео.htmlsi=Qmt2wTn2jftrOnCJ
Hope that helps.
Hope that helps with some of the issues you have. Ah another thing with wire not closed and found this when working with svgs is if thre are 2 lines on top of each other. This can be hard to spot but the validate sketch will point you in the direction of troublesome vertices.
I feel like the Part Workbench is much less accurate than the Part Design Workbench.
Or at least it requires a lot more data input to achieve some precision.
The part design really restricts you in it's workflow for example limits the use of the right click, transform options, sketches must be closed, sketches can't create multiple bodies etc. The part is more free but you can still go down the same route for accuracy i. e using the position coordinates. The part wb does allow you to work with open sketches, faces, edges even vertices to create your model. It allows for a more 'organic' approach plus its full of features. It's a bit of a Swiss army knife. I will be going into some of the differences and examples of use as we progress through the series starting with the next couple of videos 😁
@@MangoJellySolutions Without wanting to put pressure on you, I can't wait to start this series.
It's like watching the season finale of your favorite TV show and having to wait 6 months to see the rest of the plot.
