Simple measurements could be made on the flat areas by using analyze distance, select "endpoint" selection mode then click the first surface. select endpoind selection mode again and click the second surface then look at the appropriate delta distance (eg. X, Y, or Z). Using this method I can easily measure the deepest dimension inside the part at 60mm.
For more difficult surfaces that are curved or on some plane other than the system axes you will want to use a method more inline with what Cadcam was suggesting with projecting points... |
