I created a custom sub-assembly recently and added it to the assembly I'm building my corridor from. After that I can no longer create multiple section views as the software just hangs and has to be rebooted each time I try it.

It's a fairly simple sub-assembly (a red concrete strip with a subbase) that fits in between two carriageways.

Below is the coding diagram for it.

Can anyone tell if there is something wrong with this? Before I attached this sub-assembly I was just using a standard carriageway sub as a placeholder and there were no problems with creating multiple section views.

I can create an individual section view with this new arrangement, just not multiples.

Any advice would be appreciated, thanks.
