Hi.

Check this out. It's not a hard task for my machine. You'll need "Human" plug-in.

No plugin, just sort and filter by 'Brep CP' distance:

Thank you guys but maybe I have not been clear enough. I am aware of this way of extracting the boundaries. Both your solutions include making a planar surface and splitting it with all the curves. Using the test data this task takes 2.3s (according to the profiler). This is equally computationally intensive task on any machine and this is the part that I am trying to optimize. The test data has 134 curves. I am trying to complete that task on 40 000 curves.

Do you have any suggestions on optimization? Any suggestions on avoiding having to using all curves for surface generation and all curves for surface split?

So, you want to be able to create the boundaries consist of 40000 curves all at once and find the area to apply hatchs?

It may be easier if your curves are polylines and already forming regions but your curves are not consistent at all.

Perhaps you'll need special coding for this task or would be helpful to work with separate areas.
