Hi everyone,

I'm currently working on a project in Abaqus/CAE and I've encountered a step where I need to create a datum point by projecting onto a surface or edge. I'm trying to understand the underlying logic of how this feature works.

Could someone explain the internal logic or methodology that Abaqus/CAE uses when creating a datum point by projection on a surface or edge? Specifically, I'm interested in understanding:

1.  How does Abaqus/CAE determine the projection direction?

2. What are the criteria for selecting the closest point on the surface or edge?

3. Are there any specific settings or options that can influence the projection process?

Any detailed insights or references to documentation would be greatly appreciated. Thanks in advance for your help!
