This is more than a display error. It is a strange problem. F.e. deleting the line for the back wall of bedroom 2 fixes the problem somehow. Not that that is a solution of course.

Thx for the file and effort, It appears I will cont. with my intro into Arch/Bim using this method, or as you suggest ignore.
However, I do request this to be raised as a bug, WIZIWIG If your a relative new user flags will be raised if you are getting gaps in your walls. When your opening a cad package and your having trouble with this basic process, and you really shouldn't have to do things twice to get a flawless result, to me that is the definition of Bug!

This is a known problem I want to fix for a long while

I use Sketch as base of Wall a lot, but seldom drop into this problem, you may have a look at Villa Savoye or github. An ugly and tedious 'workaround' is to make a construction edge with the (half) width of wall to set back the edge ... maybe someone want to attack this ?

I redrew via sketcher / pad & to find Hole 0.00mm caused problem regardless I found a happy hole depth at 400mm. Not sure why the generic 0.00mm pockets the adjacent wall? Also sounds like a bug!
Thx for the help, V's No.12 should return useable CAD?

0 means automatic, but somehow it generate a subtraction volume, when use complex sketch as base, which cut adjacent wall segment.

People who do not use complex sketch has no such problem.


Prepared to improve the algorithm, see Cutting hole depth

FC:-19.3, FC:-0.20, FC:-LS3

1. Use Draft -Problem: Draft is not Parametric
2. Use Simple Sketch- Wall connection Rendering Problem
3.use 3 sketches as layers 1st sketch parametric grid, 2nd Sketch drive grid & wall constraints location & Thickness, 3rd prepare wall for Pad. (Problem Attached)

Sketch goes into meltdown.
file included.

So at this point in time, to have a flawless parametric rendering isn't achievable - I hope these files & comm's help the dev's. Thx for the software.

Draft Line / Polyline is parametric, you can use Edit Polyline to do editing. But it does not have constraints which to me are very useful for organisation and revision indeed so I stick with Sketch

You has to link the same, no file attached.

For anybody want to attack this, I can describe the algorithm behind and the line of code relevant - in gist, the created wire for the base face of the wall is self-intersecting and after Part.fix(shape), the portion 'self-intersecting' become blank instead of face...

Ok Glad you all know about it, I went to sketch parametric grid FC 0.19.3, then sketch on top to lay the walls down still got an error of 1 void in the Bedroom 2 wall.

I am now convinced FC 0.20 LS3.118 are unstable.
ON WINDOWS 10
PS. Thx for all the work you guys do - I wish I contribute more

.

if you know freecad well and use it accordingly, it is very stable, especially under linux (xubuntu lts)

Not sure what you are attempting ? To workaround the problem, I would set back that edge by adding a constraints e.g. in this case by 1/2 of the width of the wall.

Why are you creating a grid in separate Sketch and create Link To External Edge ? This is not 'toponaming' stable in fact.
