Am familiar and used to the capability between Inventor/Soliworks and Mathcad 15 on a 32-bit machine.
In trying to keep up with the times this funcitonality is no longer available.
Does PTC intend to re-introduce this capability? or has anyone developed an up-to-date version to work with Prime on 64-bit?
... Timeframe for Solidworks 12-13 integration will most likely occur in the release of PTC Mathcad Prime 4.0...
