Glen and Curt, I understand how to control things when auto-building roofs, but CA is poor in auto-building complex, multi-pitch, multi-height, multi-angle, multi-style roofs. In complex situations, it's much easier to draw the roof planes manually. Unlike auto-build, manual placement doesn't offer any control over the critical parameters prior to creating the roof plane; and after the manual roof is placed, the dbx is nearly useless in terms of setting up a consistent, accurate heel height. What I need is the ability to edit a roof plane and control the heel, seat cut, etc.

The problem with modifying the roof baseline is that with auto-framing turned on CA will raise the effective plate height to the new baseline height. I can turn off auto-framing, and then the sections will behave, but then I have to give up auto-framing.

We just slapped some low-end ($150) 2GB Nvidia GeForce 780Ti cards into our five year-old workstations. There has been a great improvement in the speed of all rendering methods except Painting and Watercolor, both of which are still dog slow.

I placed the roof planes with a 12" rafter, just as a starting point. If I draw a truss, the profile is completely screwed up, because CA doesn't know what to do with what is essentially too small a heel height. So, yes, the heel height is controlled by the roof plane; the problem is that with a manually drawn roof plane, I can't go back and modify the heel height, say to 16", which is a realistic figure and will allow CA to draw a satisfactory truss profile. Modifying the rafter depth doesn't do anything - with a 8" pitch on my manual roof planes, CA always calculates a 10-3/4" heel, no matter what my rafter depth is (even if I enter 100', it still calculates a 10-3/4" heel). So, I was hoping somebody knows another method of controlling the heel for a manually drawn roof plane. Or, maybe someone can confirm that I'm screwed, instead.

I've manually placed some roof and ceiling planes. Now I want to add trusses and be able to control the heel height precisely. I know about trusses and the auto-build roof procedure, but it is often easier to place roofs manually. Messing around with the rafter depth is hit or miss, since CA doesn't allow independent control of how the rafter seat is cut. If anyone has a suggestion for me, I would appreciate it.
