It's cool that you use MoI this way - this is really one of the main target areas of MoI, trying to have something that has a more light and fluid feel for just drawing stuff quickly. That kind of thing can be nice in the early design stages, and it makes for a nice companion to use alongside another more heavy duty CAD program as well.

I'm glad that it is working well for you! :)
