What is the typical IGES import procedure?


  1. Run the import with the options selected adding "Remove Duplicate Surfaces" and possibly adding "Auto activate part". To check if the imported file is a solid,
  2. Change the pick filter to shape
  3. Inquire - Entity and pick the part. If the status window says it's (Closed), it's a solid. If the part is (Open) you need to sew.
  4. Click on the Heal Toolbar
  5. Sew (Use default tolerance the first time through). If the result says "unmatched edges = [0]" you have a solid. If not [0], check the gap. If it is reasonable, rerun the sew command with 'Tolerance' that matches the gap, +1 at the least significant digit.
  6. Heal topology - check both option boxes - Set tolerance to your Default tolerance - if you had to sew at a tolerance other than the default, this will bring the part back to the default tolerance. It also will delete most duplicate surfaces if they came through with a non-native import.
  7. If there are more edges open, use the command 'Show open edges'
  8. First attempt to close should be to use the 'Extend Faces' command. Typically where there is an open edge, there are two. Pick twice to extend both open edges.
  9. Second alternative, if extend doesn't work, would be the 'Fill Gaps' command. Maybe there is a full face missing, (more that just two edges).
