Can't attach dimensions to objects in drawing

philmat15philmat15 OS Professional Posts: 12 PRO
I have created drawing of a part, imported as a .stl file that was generated in Solidworks.  I want to dimension the diameters and the spacing between the centers of several holes but I'm unable to attach the dimension tool to the edges of the holes.  Also, there are some lines in the drawing that I can pull a linear dimension from, but not all of the lines.

    STL is not a precise format (Why STL from SolidWorks? We can read SLDPRT natively), therefore it is unlikely to play well in Drawings.

    Thanks Neil.  I will have my client send the SLDPRT file.

    If they are reluctant to send the actual part file, ask for a Parasolid file. SW and Onshape both use the Parasolid kernel so no translation occurs and geometry fidelity is 100%

    Thanks Neil.  They did send the SLDPRT file.  I know that Parasolid works because I can import those file types (printed circuit boards) that I export out of Altium Designer.  Thanks again for your help.
