"How to Define N1, N2, N3 Points for positionmark in Scripted Mesh Mapping?
Hi senior developers,
I’m currently working on developing an automatic mesh mapping script. The main purpose is to allow duplication of meshes onto repeated identical geometries in the model using a script. The panel function I’m using is the *positionmark API.
However, I’m encountering a problem: the *positionmark API requires defining three positioning nodes (N1, N2, N3) on the geometry to correctly align the parts. My question is: how can I define N1, N2, and N3 individually within the script?
My initial idea was to define a coordinate system within the geometry and use that for transformation, but due to my current scripting skill level, that approach is a bit difficult for me to implement. So instead, I thought about just finding matching points on the identical geometries.
For N1, I’m currently using the centroid of the geometry (via hm_getcentroid). However, I’m unsure what would be suitable for N2 and N3. Does anyone have any suggestions?
*positionmark
