Attach a Datum to a GTOLHere is a summary of the responses:
a.. ProductView Express is an iE plugin that will allow you to view Pro/E files. b.. If it is a recent drawing - Wildfire generation - ProductView Express will view a drawing. The old file formats didn't save the required graphic info.
c.. Actify Spinfire has free viewing I believe.
Although eDrawings was suggested in the message below, it requires the drawing file to be published in a eDrawing format (similar to PDF files)
Thanks for all the suggestions. In the past, whenever some needed to view a fully dimensioned drawing, I published it as an eDrawing or PDF file.
