Hi,
I'm having problems with the Fuse Arch.
In small test models it works, but when the model becomes more complex it stops working, some walls merge, others do not, both in plan and in facades.
I have not been able to solve the issue, is it a known bug?
What would be the workflow for Fuse Arch to always work?
Hello @Carozo, I think you will get more feedback if you post on FreeCAD forum.
From my previous experience I can say that in FC you have to keep the objects count as low as possible, but perhaps @yorik, @bitacovir or @paullee can give you more support.
Thanks @carlopav
@Carozo Do you mean Draft Shape2dView Fuse Arch attribute ? Or TechDraw ArchView Join Arch attribute ?
Please post your workflow, model and screencaptures for ease of understanding by others. May post at FreeCAD forum for more exposure :)
Hi @paullee ,
Draft Shape2dview
All the walls have the same material, on the façade there is no way for it to work.
All the walls were built from lines, to have each wall separately since it is the best way to take measurements.
The "Fuse Arch" mechanism indeed fails often to remove lines in projected views (basically when using "Solid" mode). This is because when unioning (fusing, in FreeCAD terms), the OpenCasCade engine leaves edges and faces as they are, it doesn't unify faces. We have implemented a mechanism in FreeCAD that does that (Part.removeSplitter()) but it's still not perfect and leaves lines quite often... For the time being that's a limitation we have to live with, but we're looking at ways to solve it.
Hi @yorik , thanks for the response. The solution I found was with "Face Binder" which also gives me the possibility of calculating the quantities of façade finishing materials. I think I'll use that workflow to solve it
A simple test, Fuse Arch works to combine different ArchWall, ArchStructure, both on plan and section. When it goes complicated, it may fails indeed :)
@Carozo Care to file a bug report in FreeCAD github to see what it particularly fails at ? Thanks :D
(FreeCAD file renamed as .zip to make it possible to be uploaded here, rename it back to .FCStd for it to work)
A good way to test, is to select several objects, make an union with the BIM union tool, and set the "Refine Shape" property of the result to True and see if some edges were not removed
The last test check how Shape2dView work with different Arch Wall and Structure objects - see annotation.
The 'void' in section is filled up with solid hatch unexpectedly
Arch Wall and Structure are fused together - expected behaviour ?
Add a Section Plane in front of the objects now, i.e. an elevation, then it shows
