BIM Workbench

What server?

Sorry, I mean a external server, like BIM Server or similar that could manage this process trough a FreeCAD api or similar.

hi guys,
What do you think is the best solution to deal with the size of the files? Currently I am able to connect to my BIM Server (1.5) and keep the session open, then select my project and the revision that I want to download. (I divided the process in 3 steps since FreeCAD crashes dealing with big projects). But my main problem is importing the IFC file, sometimes it takes a really long time, so if I have 2 or more architects working on the same project it would take ages to download, convert to IFC, import the IFC to FreeCAD, and then the other way around.

I really don't know how we can have a single file (project) that could be shared with the users. I thought BIM and IFC could be the answer but i am a little bit lost about how to do it, what do you guys think?

Slightly sidetracking (sorry), but how do you set up bimserver and or other collaborative environments in freecad?

And a noob question - can IFC files be directly linked into Freecad?

@yorik, just FYI when running test framework on the below FC appimage this is what I see when it opens the BIM WB:

Actually that's another point to optimize, the giant parsing operation that starts at https://github.com/FreeCAD/FreeCAD/blob ... FC.py#L340 is inefficient and takes a lot of time. We could optimize that a lot by using the inverse attributes of IFC objects, that IfcOpenShell now supports very well

Yorik, would it be possible to give a short example how this works ? You may be did already but I can not find it.

Basically at the moment we have many for...in... loops that scan the whole IFC file contents to extract relationships. However, IFC object can inform themselves of their relationships, thanks to inverse attributes. So the idea would be to, for example, for each of the relationships dictionaries created at file opening, find each place where they are used in the code, and replace with the appropriate relationship attribute.

Oh right... we now have a test that activates each installed workbench... I'll see what can be done there

[yorik]

Ok this should be solved now

[Kunda1]

Ok this should be solved now

Will test when new appimage comes out (~1 week from now)

Hello!
I recently installed FreeCAD version 0.18.4 installed on a machine running Ubuntu 18.04. I also installed IfcOpenShell by following the instructions at this link: https://wiki.freecadweb.org/Arch_IFC. Then I tried to do the exercises in this YouTube tutorial: https://www.youtube.com/watch?v=Jc12_G5DFF0. But when I got to the point in the video where I needed to use the IFC Elements Manager buttons, they were grayed-out and I could not activate them. The only button I could activate was the Classification Manager. I am a bit of a newbie to Linux and a definite newbie to FreeCAD, so if you have a fix that can be implemented by someone who is just now figuring out what sudo-apt-get means, that would be great. Thanks!

Consider using the development version if you're interested in working with BIM.
AppImage is a very nice way to get started with v0.19_pre
You can also try the FreeCAD Daily PPA
