Re: Sled brake: how to fillet?

I announce victory! Thank you Thomas for the handholding, and chrisb as well for the insight. Opened FreeCAD again for the first time in a few years and it was somewhat arduous, but fun. 0.21 looks good! Chamfer instead of fillet because I ended up liking the look more (also prints nicer): DSC_0061....

Re: Sled brake: how to fillet?

Did it with a sketch. It's closed and passes all Validate Sketch buttons.
I can Part -> Extrude it, looks normal to me. But I can't make a fillet, recompute fails. See attached file.

What am I missing?

Thanks, making progress. Now when making the 3-point arch, despite clicking exactly on the edge endpoint, and it getting highlighted ...

Re: Sled brake: how to fillet?

Off topic: Are you sure that a 3D printed brake is something safe? Conditionally. It's for "Schlittenpisten" (i.e. fairly slow speed) or tiny hills. When the previous brake broke apart, we just used the boot on that side. Works, but less comfortable. And the way I'm printing it (full infi...

Re: Sled brake: how to fillet?

I'm struggling with this picture here: Bildschirmfoto_2024-01-14_09-12-48.png If I use e.g. Box selection to select just the vertices/edges of the curve, deleting still removes the whole cross-section (which seems to be of type PartFeature ). I can do Draft -> Draft to Sketch and remove the vertices...

Re: Sled brake: how to fillet?

Thank you for the speedy reply and the file! The portion filleted there is the bottom end (brake/scraper), while I need the top end (handle). Trying to retrace the steps from your file: - refining the whole geometry gives me a "clean" bottom end, and I can fillet it, looking similar to you...

[solved] Sled brake: how to fillet?

FreeCAD 0.21.1 on Ubuntu 22.04 As commonly happens in the skiing season, the cheap plastic brake on our cheap plastic sled broke. Now I have a replacement in STL format, which after 3D-printing fits perfectly and works nicely. The only remaining issue is the edginess of the handle. I'd like to round...

Re: Macros to python script issue

I do a lot of bulk processing in FreeCAD and most of my macros are usable both from GUI and via script. Unfortunately there is no official way to support this nicely ("somebody" should change that). I need something similar to what Tobi has shown, so most of my scripts have this section pa...

Abusing FeaturePython Proxy kills save files.

Tested on FreeCAD 0.18.2 and 0.18.3 on a Debian and two different Ubuntu releases. The issue is based on bad usage of the FeaturePython.Proxy member, where the error case should be handled much more gracefully. WARNING: use a document you don't care about to test the following code. We assign a Qt w...
