My situation is for given two entity, how to determin if they are the same entity, despired their transformation,ie position.Is there a ACIS api for it?
What I come out first in my mind is to compare all the vertex, surface, ...etc. Thanks!
This is currently no api in ACIS which can do that. Identifying two random objects in space as same is a complex problem and I believe still a research topic. If there is no scaling transform you can try the simplest checks first i.e topological checks, surface area and volume checks and then go on to developer the detailed checks.
