I'm in the process of building a GDL joist hanger and I've come across a problem using groups. I'm using 2 simple prisms to create the basic shape, and using 2 more prisms to cutting out the geometry using the GDL version of SEOs. This is what my geo...

I have a regular problem with Physically based rendering on my Intel iMac Pro, where the display will go completely black. This happened in OSX 13 Ventura in the technology preview. I thought it was a glitch, and when OSX 15 Sequoia was released I up...

Has anyone ever scripted any graphing or chart objects that can be used for (say) space type analysis with Schedules? I am working on secondary school extension and key to the process is analysing use of space to identify waste or surplus. The princi...

We have a multi-platform environment in my office, using Macs and PCs. Until Bimcloud (we use the SAAS version) we had a bit of a problem with library paths between Macs and PCs. Although that is now resolved, we are moving towards replacing our doma...

Just when I think I've got the hang of these, I get a really complicated one I can't seem to fix. GDL has no IFS or AND/OR/NOT options, so every condition has to be covered with a separate if statement. I can make this work - up to a point. More than...

The other option is a curtain wall. That's always reliable and has more flexibility. However the new AC28 international Library may have additional objects you didn't have access to previously, chances are that you may have an option in another widow...

Object attached. It could be improved with better hotspots (particularly for scaling in 3D) and making the object scaling more consistent between the 2D and 3D elements. They are kind of okay, but I'm not very good with hotspots!

How about this? Happy to share the gsm file. It has a 2d representation (simple shaded circle) and a 3d one. As with all my GDL objects - modifications/improvements are actively encouraged!

All done and uploaded to BimComponents. Modifications actively encouraged! I haven't added options for skewed hangers, that would take quite a lot of my time and there's only so much swearing my colleagues in the office can tolerate, especially now u...

All working in 3d - just the 2d to complete!
