i have one question regarding the Area Component.
When i have some surfaces projected on XY- or YZ-Plane everything will be fine and the operation will be completed in 400 ms.
When i project the same planes on XZ i have to wait 6.7 min for results.
Why ist this so?
No. The projected surfaces just don’t join in that case, partly because many of them overlap, though I didn’t analyze that aspect of it. Disable Area and examine what’s happening before reconnecting it.
@HS_Kim avoided the problem by running the surfaces through a Crv param before Project, followed by RUnion to get a single perimeter curve, so Area is executed just once.
A trick to reduce calculation times, especially for Area and Runion, is to break the large set of areas into, say, 6 groups, union those, then union the result of those. Doesn’t always work, but in a project with some 1,300 elements to union, it reduced time from 22 minutes to about 70 seconds.
