Strange walls

[t.lemaitre]

Hi,

I'm creating my house in FreeCAD and I encounter a problem with a wall based on a sketch.

The ends of the problematic wall are not perpendicular to the rest of the wall.

It's really strange because I drew many walls based on sketches without problem ...

Look at the attached file and the attached image, there is three walls :

• Not good (red) : the wall which causes my problem, based on a sketch
• Good from draw (orange) : a wall without problem, based on a draw
• Good from sketch (green) : a wall without problem, based on a sketch

Hi, also tried 0.17.13541 (AppImage on Fedora) and have same problem.

Two suggestions:-

1. Use latest 0.18 (0.18_pre) / 0.19_pre - Tested and no problem with Version .018_pre 16093 (AppImage on Fedora27 - FreeCAD_0.18.16093.glibc2.17-x86_64.AppImage)
2. In addition to above, if you like to experiment, use 'further bug fix' in discussion thread which attempted to fix other problem in ArchWall

I'm guessing t.lemaitre is using the Ubuntu freecad-stable PPA. We're currently in the process of packaging 0.18.16093 for said PPA, but I'm having trouble with it (I want it to be switchable between Python 2 and Python 3 like the work kkremitzki did for Debian and which will be included in buster). In the meantime, the freecad-daily PPA can be added as an alternative, it's currently frozen to the 0.18 release. The package name is freecad-daily and based on Python 2.

AppImage run on Ubuntu?

FreeCAD_0.18.16093.glibc2.17-x86_64.AppImage

[NormandC]

Yes of course, as far as I know, this AppImage is actually built on Ubuntu. But with the PPA, FreeCAD will be part of the system packages, and be automatically updated.

[t.lemaitre]

Thanks for the advice but yes, I'm still on the stable ppa.

After more reflection on the wall I wanted to draw, I found another way to resolve this problem : I drew the horizontal surface the wall needs and then use Arch > Wall.

Actually, this wall has not exactly a rectangular horizontal section and it seems me it's the better solution. Look below :

Glad your case needs something else and you find a better way

And just start a thread to discuss the most wanted features / development roadmap - maybe ArchWall can support your usecase out of box? or other common features you think of?

The issue with the non-perpendicular end faces can be solved by performing a recompute.

BTW:
I find it strange, contrary to what you would expect(?), that a newly opened document can be in a state where a recalculation has to take place.

IMO this is something that should perhaps be fixed.
