no issue here.
I think your make a mistake due to the shape binder. it make the face looks like it is broken. but no ;)

Hello,

I'm new here, wanted to get into technical CAD for a long time and finally gave it a try.
I started with the reddit Cad-Challenge#11 and after I solved the beginner-level and lost my progress in the intermediate a few times to crashes on undo I finally got stuck on the last steps.
The drawings require me to add a fillet on the pipe-joint.

I can't find a way to do this; is it even possible in 0.16?
If it isn't, is there an elegant workaround?
I haven't yet figured out how to compile from source on fedora( as I'm kind off new to linux as well).

I'm looking forward to your reply
Leopold

Yes it is possible to do in FC 0.16. The Fillet feature exist in (at least) two places. In Part workbech (https://www.freecadweb.org/wiki/index.p ... art_Fillet ) and in PartDesign ( https://www.freecadweb.org/wiki/index.p ... ign_Fillet )
see attachment i used both on the same objects you can show and hide them with the space bar

Jee-Bee replied while I was typing, we say some of the same things.

That should not be happening. If it is repeatable could you please post a file and step by step instructions on how to get FreeCAD to crash? Your version data is missing some information unfortunately, which is possibly due to packaging at your distro, what Linux are you running and where did you get your FreeCAD version from?

That should be easy, but the exact answer depends on what workbench/work flow and sometimes there will be issues likely from the CAD kernel OCC used by FreeCAD. Also the OCC/OCE version you are using is now very old, but it is typical for that FreeCAD version and can not be simply updated without also re-compiling FreeCAD.

If you could post the FreeCAD file we could answer your question properly but without it we really can't except to say, select the edge and click fillet.

Note that I managed to add a fillet on one side but the two edges on the other side are still not behaving.
TopOpeBRepDS_DataStructure::Point is the mouseover on Fillet001.

I will try later if I have some time. It happened while sketching in the PartDesigner Workbench.
I use fedora 2425 and installed freecad using the dnf-distro.

Oh, I visited the github but didn't notice. Thanks!
Edit: And I can't open any of the AppImages for some unknown reason

I tried it here
OS: Ubuntu 16.04.2 LTS
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.17.11495 (Git)
Build type: None
Branch: master
Hash: 9e7eb3bc2c7b6d374f165b7b938da475a422763b
Python version: 2.7.12
Qt version: 4.8.7
Coin version: 4.0.0a
OCC version: 7.1.0

The solids do not pass the Part WB Check Geometry test with the extend BOP checks enabled.

I don't have time just now to work out why, hopefully some other will.

If i remember correctly it was confirmed in the past AppImage works on Fedora 24. Therefore likely you didn't mark the downloaded package as executable? This step is needed or it won't work.
