Martin and John,
Glad to see you participating in the Beta program, and using the software! Please try to keep questions about VX.1.2 in the Beta forum for feedback though...
With regard to the model assignment and re-use for future designs, PADS 3D is able to take advantage to the assignments already done. “Update Library” allows to save your current assignment/alignment information to the Central Library for integrated projects, and to the Reuse location for net list projects. It will be automatically picked up for new projects and also can be updated in current designs by the “Update Models” functionality.
