When opening the .step or .x_t file in Solidworks, it showed 'imported' in feature manager.
Then the imported body was moved by copy/move bodies feature (using contraints).
I just deleted (or suppressed) that copy/move body feature, the body wouldn't comes to its original position.
It affected my total feature manager (almost finished my design ), because sketches and reference geometries were created with respect to the imported body.
Then I tried another way. That is I copied the imported body (1 no), then deleted the imported body, Created reference geometry and sketch with that copied body.
Is any other better way to solve this problem?
