Pretty new to SoftPlan, so forgive me if this is an easy fix. ;)   I am working on a timber frame pavilion, where the roof is to be constructed of 6" timbers, with 1 1/2" T&G V-match, then 2x6 rafters, then 5/8" sheathing, then standing seam metal. The reason for doing 2x6 rafters above the V-match is to raise the height of the roof so that the timber is visible below the soffit. See the screenshot for my detail.

How do I draw this roof so that it generates in 3D? Do I need to create a "second floor" with a second roof above the first?

I don't know of a direct way to do this but you could do a layered approach to achieving that.

 

My best guess would be to first put your roof in with a taller heel, this would achieve the 2x6 rafters, sheathing, and standing seam. Then in ceiling mode you can put in a ceiling that is composed of your T&G and finally you could put in joists or beams (still in ceiling mode) that are set to match the roof pitch. This should be able to duplicate what you're looking to do but you might have to do some math and turn off cleanup in order for it to not freak out.

 

Hope that helps!

Doing the T&G and timber in ceiling mode is one way (probably easiest). As Colin says, do your math for the offsets. Then turn off cleanup for the ceiling and set the join on the timber to 0'-0" so you can set the tails outside the walls where you want them and be sure to uncheck clean up on just about everything. You may also be able to draw the timber with T&G on the main floor as a roof, then create a second floor and stack the upper roof framing as you suggest. Do not set the upper roof to be a multi floor roof if you want to maintain separate control, but it may work decent either way.
