Rob,
Hi and welcome to the SimV Home Cockpits forum section.
The Serif package that I use is only for creating the panel facing graphics. It is not a "CAD" package. For drafting/design type work I use Drafix Quick CAD for 2-d work and Design CAD for 3-d.
Here's Serif's line of products:

It will continue. ;)
best,
