Adding window breaks other extruded items in cut

[cox]

Some times FreeCAD does not like lines planes, lines etc from two different parts to occupy the same space when cutting or merging parts.

In the file "demo_window B + wall2+window"

If you change the extruded length from 200.00 to 200.01 you make sure that you cut away more than absolutely necessary. And you remove one place where the wall face and cylinder face are coplanar.

This works for me.

Hi Cox,
thanks for your tip.
I tried it, yes it works, (apparently), the error disappears when I set the length to 200.01 or more, but if I save the file, and reopen it again ,the error is still there...

Sorry, I have no answer for you when it comes to the error coming back after reopening the file. It happens for me as well

But when I try, it seams like I have better luck using Part design and pocket a sketch through the wall.

The following quote is from this post:

Hello,
I've tried many releases of version 0.16, but still not working with extrudes.

Hi, when I open the file you attached in that post, "Extrude" has an error - it shows the red exclamation point in the hierarchy tree. Running the Macro "ForceRecompute" fixes that problem.

But instead you might want to select Extrude in the hierarchy tree, change the Data Tab > Solid Property from False to True, and see if that helps anything...

Edit: fixed the hyperlink, which had contained a reply mode.

Hi,
thanks for your reply
yes, setting extrude solid property to true (or just changing from true to false or false to true) makes the error disapear, but if you save the design, close and reopen it, the error is still there.
Where can I find this macro ? it is not provided with the application..

I found it
# -*- coding: utf-8 -*-
# Force Recompute
# macro provided by shoogen

import FreeCAD
for obj in FreeCAD.ActiveDocument.Objects:
obj.touch()
FreeCAD.ActiveDocument.recompute()

but it has the same effet as changing properties: error disapears, save, close and reopen: error comes back !

Yes, I see. No matter what I do I cannot solve the error in Extrude. It always comes back when the FreeCAD document is reopened. At first I thought that the Height Property of Rectangle being -300mm might be the cause, but changing it to 300mm didn't work.

Did solving issue #2449 also fix issue #2403?
