How to Convert EASM to SLDASM...
"An eDrawings file (labeled with the .easm extension) is primarily utilized by the eDrawings program, which is itself a sub-program of the SolidWorks design suite. The SolidWorks design suite makes use of many file types, including ".sldasm" files. Since the eDrawings program is part of the SolidWorks suite, you can easily convert an eDrawings file to a SolidWorks file by using the eDrawings' main menu."
Select "File" in the menu bar of your eDrawings program.
Select "Save As." Select the "SolidWorks File (.sldasm)" option in the text bar next to "Save as Type."
Select "Save" in the "Save As" menu to save the newly converted file to your computer."
Hello Ben,... yeah, it's wrong.. and I would guess he has it backwards... that is, not many people know you can open a *.sldasm (or sldprt, slddrw, *.prtdot, *.asmdot, *.drwdot,..*.step, *.iges, *.stl, *.dxf, *.dwg, (and inventor, pro/e, catia)) and Save As *.easm or *.eprt or *.stl..
