Thank you, TIG!
This is big, big news to me. It has just saved me tons of work that I have always regretted having to do. I had never thought to try this. I am now the hero of the office! Yay!

I love this plug-in! As soon as I saw the video I had to buy it.
One question that I think hasn't been answered (and forgive me if it has been) has to do with adding textures to a profile.
I created a wall profile that was then used to create several walls(Placement Point: Bottom Left). When I try to add a texture that has a definite vertical orientation, it seems to rotate the texture to the horizontal(in direction of extrusion). Exploding the group and then adding the texture seems to work but adds a few extra steps that I would rather not take. Is there something that I am missing? Or is this a Sketchup thing? (Follow me appears to keep the orientation right BTW.)
Thanks in advance.
