Is there a fast way to find the closest faces of a Target on a body having > 10000 faces?

Hi,

I know about the ACIS Api function api_entity_point_distance which seams to be able to do the Job.

Is there any equivalent in the RS Api I don’t know about?

Those three faces have normals which are (Counter)ClockWise almost perpendicular to each other.

From the Travel vector’s (Path’s) Point of view these faces form a U, where the target would be underneath the U.

Any Help would be very much appreciated.

Cheers,

Rolf
