Import STEP File Example (VBA)

This example shows how to import and repair a STEP file.

'-------------------------------------------------------------------------------
' Preconditions: Verify that the specified SOLIDWORKS part document to open exists.
'
' Postconditions:
' 1. Opens the specified SOLIDWORKS part document.
' 2. Saves the SOLIDWORKS part document as a STEP file.
' 3. Closes the SOLIDWORKS part document.
' 4. Imports the STEP file created in step 2.
' 5. Runs import diagnostics on the STEP file and repairs any bad faces.
' 6. Creates Imported1 in the FeatureManager design tree.
