There are some other options to go about this process.

  1. With a facetted geometry, you can select the triangles to place into named selections and proceed directly to Mechanical with the facetted geometry. This works in the latest 2023 R1. While this works, it may be cumbersome to rotate/pan/zoom in Mechanical because the 100,000s or millions or triangle data can be hard on display.
  2. So another option is to right click on the body in the Structure tree and choose "Convert to solid > Merge faces." Then assign named selections, Then transfer to Mechanical. While this makes simple CAD surfaces from flat portions, and reduces the triangle count when proceeding to Mechanical, you still can have a lot of triangles/faces and get a lot of edges.
  3. As Aniket alluded, convert to CAD geometry first by using "skin surface" or other solid tool techniques to create the solid when there are symmetries present.
  4. If you have converted the facetted geometry to CAD geometry, you can make sketch points that lie on the geometry. If the sketch point and solid body are under the same component (or root component), it will embed the point as a vertex into the face. The datum point tool that is in the Design ribbon will not embed, and so will not transfer to Mechanical.
  5. For free floating points, create origins at points as Aniket suggested.
