Good morning

The Arch's presets are working well in FreeCAD 0.17. There is a curious thing with the windows.

1º) I've drawn a wall, which is not parallel to X axis

2º) I try to draw a window and I have two situations:
if I move the cursor down and left all is correct

if I move the cursor up and right the window takes a mistake normal

This is the end result

If the wall is 'wireframe', in all situations the normal is wrong

Frequently, I like to draw the windows from scratch, and in FreeCAD 0.17 I am having problems.

In this last case, the normal is correct but the window takes the placement of the base sketch, when the window's placement must be angle 0 axis (0,0,1) position (0,0,0). And it doesn't also execute the removeComponents.

Running the Python command 'Arch_Window' failed:
Traceback (most recent call last):
File "/usr/lib/freecad-daily/Mod/Arch/ArchWindow.py", line 432, in Activated
FreeCADGui.doCommand("host=Arch.make"+Draft.getType(host)+"(FreeCAD.ActiveDocument."+host.Name+")")
File "/usr/lib/freecad-daily/Mod/Draft/Draft.py", line 171, in getType
if "Proxy" in obj.PropertiesList:

'list' object has no attribute 'PropertiesList'

am I loosing anything?

Thank you

About making windows from scratch, in FreeCAD 0.16

Code: Select all

>>> sketch.Support
(<Part::PartFeature>, ['Face1'])
>>> 

in FreeCAD 0.17

Code: Select all

>>> sketch.Support
[(<Part::PartFeature>, ('Face1',))]
>>> 

lines 415 to 418 in ArchWindow.py

in FreeCAD 0.16 this operation works fine

Hm indeed some bugs seem to have appeared when creating windows from a sketch, I'll look into it...
But for your first problems, everything seems normal here, I think you probably didn't snap correctly to the face. Try enabling the "nearest" snap, usually it works better

It does not a problem. I commented it because it seems curious.
The issue seems to be that I define the wall's face as working plane (I was drawing something in the face). If I maintain the original working plane (xy), the mechanism is much more precise. Please, forget it.

Yes, the improvements in the sketcher module. This really is important.
Thank you

Good morning:
I would like to do a more regulated description of the problem "creating a window from scratch in FreeCAD 0.17".

The steps to reproduce the 'bug' are included in Window's wiki page (http://freecadweb.org/wiki/index.php?title=Arch_Window):

Creating from scratch
Optionally, select a face on the Arch object where you want the window to be incuded
Switch to the Sketcher Workbench
Create a new sketch
Draw one or more closed wires
Close the sketch
Switch back to the Arch Workbench
Press the Arch Window.png Arch Window button, or press W then I keysquote

The problems are two:
1º) when the new window object takes its base object in ArchWindow.py line 67

Code: Select all

obj.Base = baseobj

it also copy the baseobj.Placement, resulting a window with mistaken Placement.
I would like to propose doing

Code: Select all

obj.Base = baseobj
pl = FreeCAD.Placement()
obj.Placement = pl

2º) when the windowCommand executes removeComponent in ArchWindow.py line 439, it looks for a Tuple in line 415, but finds a List, resulting that the remove command is not executed
I would like to propose doing

Code: Select all

if isinstance(obj.Support,list):
    host = obj.Support[0][0]

This two patch are working fine for me, for the moment ...

I don't like much your first idea, because, if, for example, you draw a sketch on a wall, if you do that, the window will not be placed on top of the sketch. I actually don't see what case this would be fixing?

Your second proposal I just added in git commit 008fed6.

I don't like much your first idea

me too ...

Hello Yorik
I can confirm that the sketch-based window location bug remains

Hopefully this should now be fixed with git commit 6b8b3ec
