I was just wondering if anyone else has had this problem or if it is normal?..... I have imported a very basic .iges file from a customer and saved it as a .part file and made a basic drawing (see attached). The model saved at a random angle so I added my own normal to front view to use in my drawing, I used smart dimension to add the dims but as you can see from the bottom right view (my saved normal to view) the height is shown at 225.6 when if you look at the projected view to the left the height should be 218.3 and the 225.6 has actually picked up on the diagonal corners if that makes sense. I wouldn't thought that was possible? If I use vertical dimension on my front view it measures it correctly.
