Thank you, Nathaniel.
I learn something new every day.

I had a project today that I really could have used a 6/12 pitch monotruss for. Have you considered making the pitch configurable? I'm getting more and more "modern" designs with combinations of different pitches of roofs, in different configurations.

Has anyone figured out a quick and easy way to define section lines in Layout from their sketchup file?

You would think the odds would be 50%.
You either get it right, or you don't.
But I get it wrong 90% of the time.

I'm just going to keep saying tomorrow, every day, until it happens.

What if you "auto-hide" the trim when the move command is selected, then you would have the wall edges to inference to. Is that even possible? I'm not a coder.

Using the Tape Measure tool, measure the trailer side that you want to be 20 ft., type 20' (it should display in the bottom right dialog box(, and press "enter".
if asked to resize the model, click "yes". If the width does not measure 8 ft automatically, you will have to edit the model itself.

After creating a number of plan sets using templates (thanks Nick), I would like to combine them into a single plan set.
Other than making each set a template and importing to a new plan set, is there an easier way?
