stl selection

[Mazakdude]

I've recently installed 2021. In previous versions I could analyze points on an imported stl or select points from it inside tool paths for mill depths or drills etc. I can no longer do that. I didn't have to change a setting somewhere to do it before it just worked. My reseller said that he sees no difference between 2020 and 2021. Is there a setting that has to be changed somewhere to enable this?

There are two options now for importing a STL File. The default is 'Mesh Entity'. This is a "blob" of data, that won't let you select points from the mesh. If you change the import option to "Lines", it will then let you analyze discrete points at every triangle vertex.

I will usually import all of my STL models twice. Once as a Mesh Entity, and again as Lines, so I can measure distances when positioning the mesh model.

When you open the 'STL Import' dialog box, there will be an 'import' button, once you have changed the File Handler to 'STL'.
