I would be grateful for help or some explanation because I had similar problem before - with custom curtain wall from the same tutorial. It looks like VA has problem with dividing the objects. Usually, I would say that it is my fault but after doing the same things as in the video I should have the same results.
Hello and thank you for your quick response.
I was able to create a proper window after trying for the third time and I have an observation I want to share: after clicking “add” every leaf tab must be selected. I clicked next right after adding them and apparently they were set to 100% what caused my problems. But when I clicked Leaf 1, Leaf 2 and Leaf 3 they automatically updated to 33%. I would be glad to know if this is deliberate, just a way the program works or my observation is false.
