I am working on a robotic project which i need to find holes’s X,Y,Z coordinates and angle so i need absolut position of hole. For example can I extract the map of holes position and angles of the following 3d model from 3dm file. So, is proccess of making a hole on a solid, recorded in 3dm file? Or 3dm file just static file just contains polygon information not the project file? My clients work with a design software called GemVision Matrix which uses Rhino as 3d foundation. In which way I can get the holes coordinates information. Or should it be a plug-in to collects information of extracting position, size and angle at the time “extract” button pressed.?
