Based on reference created in Teamcenter when doing a SAVE AS in Solid Edge.

Using ST4 with SEEC and Teamcenter UA8.3, we have a lot of designs that are knock offs of an existing design. We noticed that every time we open the base designs, and perform a SAVE AS to create the new variation of the design, Teamcenter builds a BASED ON reference back to the original design. After many months of doing this, that base design has hundreds of references to it and seems to be slowing SEEC performance considerably. Is there any way to turn off this BASED ON reference in Teamcenter so it doesn’t create it, either temporarily or permanently?
