Change the Specification

In CADmep, you can change the specification of drawn items. You can select objects to change and apply their own manufacturing specifications, or change to any of the specifications listed.

Additional options including the ability to repair straight lengths (due to different connector adjusts) and if template fittings are allowed to be stretched.

Note: The Change Specification command (CHSPEC) only works across items with a common material and therefore has to be repeated for each Item with a different material assigned. The Change Specification command does not change items with locked connectors or seams.
