[ Bug ? Resolved ] TechDraw ArchView fails on some BuildingPart

[paullee]

[ Bug ? Resolved - see https://forum.freecadweb.org/viewtopic.php?f=23&t=43499#p371050]

Hi, testing the TechDraw ArchView again using the Villa Savoye model.

Found using BuildingPart as source of ArchView (in lieu of ArchSection) very handy !

Just find it works on G/F, 2/F, but not on 1/F as shown in screencapture. File of the model at [EDIT - link fix]https://github.com/paullee0/FreeCAD_Villa-Savoye

Any idea ? Thanks.

This is going to be a problem. We just put a check into master to only accept ArchSection as Source for ArchView because we were getting crashes if the wrong object type was selected. If ArchView is supposed to accept objects other than ArchSection, we will have to change that check. I’ll need some input on which Arch objects should be allowed (and how to identify them).

url is messed up.

I get bunches of messages when I recompute this file:

<string>(1)<class 'ModuleNotFoundError'>: No module named 'ArchSketchObject'
<input>:1101:6: Could not resolve property: none
<input>:180:6: Could not resolve property: none
ArchSketchObject add-on module is not installed yet
109.649 <App> Document.cpp(3204): Villa_Savoye#Wall003 still touched after recompute

Aside from that, the actual problem is that 1F does not return any Svg when requested. GF returns a whole bunch of Svg.

BuildingPart should be acceptable as indicated in the tip of the Source attribute of the ArchView, @Yorik should have mentioned it somewhere in the forum but I just can’t find it, and not mention in the wiki (yet?)

doubled the Url, fixed now.

Ah yes, I try using SketchObjectPython in that modelling, no need the module if editing the model is not required.

I suspected there is an object or a few of them that is / are not accepted and break the process, but there is no error in the report view …

@DarkPhoinix

…
Another big change, is that BuildingParts now have a built-in, implicit section plane. That section plane is always parallel to the BuildingPart’s base plane, but you can specify the offset between them. So now all tools that work with a section plane, such as Draft Shape2DView and TechDraw ArchView also work with BuildingParts. Showing a plan view in TechDraw is now pretty easy: Create your level model, create a TechDraw page, add your plan to it with the ArchView button.
…

The Arch_BuildingPart automagically includes an Arch_SectionPlane. So, I think TechDraw only needs to accept two objects at the moment, either a true section plane, or an Arch_BuildingPart. Arch_Floors and Arch_Buildings should also be accepted since they are BuildingPart instances.

Yorik’s info should be included in the wiki

Found I did not fully understand how BuildingPart works - Need to set its Placement to the level to cut the floor, it was at 0,0,0 so didn’t cut the objects … Hmmm… may need to do something make it automatic

But found another ‘bug’… probably in another post

Objects at 0,0,3300 but BuildingPart at 0,0,0

• So its section plane / ArchView does not cut at right level
• BuildingPart for 1F cut objects at BuildingPart for GF
