First things first, I think the software is pretty impressive and it promises a lot. I'm an architect, experienced with CAD and BIM for several years.
I started working with FreeCAD a few weeks ago, using the Architectural Tutorial (thanks Yorik, great tutorial with an architectural classic). If this set of questions was already answered, sorry for the unnecessary spam and please redirect me. If not, I hope we can keep this post open for further questions about the software's workflow, best practices in Architecture and BIM and other issues.
At first, I didn't understand correctly the snapping tools. The snaps seemed random, but thanks to Regis tutorials on Youtube (cheers mate!!) I started over, using the snaps correctly (almost). This second time, by distraction, I added walls to each other and now I got stuck. I need to subtract a volume because some walls intersect a small slab, and when I do it, nothing happens. At first, they were all disappearing; now, not even that. Now, I know the tutorial recommends that we shouldn't add to much stuff to each other in order to avoid unnecessary complexity, but since it is also a BIM app, shouldn't complexity be part of it? I mean, shouldn't walls, if not adding to one another, at least merge directly to each other, like in Revit for example?
Also, I see that we can model directly with walls, instead of lines, wires or polygons. That being said, the tutorial suggests that we use lines, and in some videos on Youtube, wires and polygons, like in Sketchup. Is there a reason for, in these tutorials, instead of just creating walls directly in the model with the arch wall tool, to use draft objects as a first step? I just ask because it seems double work.
Another question is the Combo View organization. As you can see on the print screen attached to this post, I tried to organize all elements since the beginning. Is the way I work with other BIM softwares and it seems to me that a proper organization makes it easier to get back to these projects after a while, as well as sending them to other people to continue the work. Unfortunately, it seems to me that my organization is not good for FreeCAD. An example is the walls added to each other and the mess that it creates in the combo view. I'm just at the beginning of the tutorial and it feels already as counterproductive method. That being said, could someone help with a another method, that fits the software better than my own?
The version I started with (0.17.something) didn't allow me to use the BIM workbench, it was always crashing. Now I downloaded the last 0.17.13528 version and the BIM workbench seems to be working fine. Experimenting with creating walls directly from the Arch Wall tool, I realize that the results are the same as before, meaning a main wall where and several others as child ones. Here I reach my first conclusion, FreeCAD uses a main object, no matter what, and other ones that may somehow be related to these ones as child objects. Now, working with FreeCAD for architectural work, what is the advantage of this? Won't it, eventually, result in the same long tree that I have in the combo view, with objects as child of other objects and so on, in a confusing diagram, hard to work with? I don't mean to sound like I'm complaining here, is not at all what I'm trying to do here. I'm really excited about the software, I just want to understand better why things are like this in order to adapt my workflow to it.
Attached you'll find the .FCStd file, as well as a print screen of what I described. Sorry for the long text.
