Transfered from EAP Ideas list
We often need to turn levels on/off in the Drawing / Sheet model. If we do this with CVE's, Mstn needs to recalc the CVE after each change to the level on/off list.
What normally happens is that the Ref would be 'demoted' to Dynamic, the levels flipped on/off, before the CVE turned back on again.
Just wondering if the Incremental CVE cache is flushed when the user flips to Dynamic from CVE? Would it make things a bit quicker if there was an option to retain the I-CVE cache (pop-up dialog?)
It doesn't seem to do so at the moment, as Mstn does a recalc of the CVE even if the user flips back to CVE without making any changes.
