I am a framing contractor. I draw the models of our houses into Sketchup, and essentially virtually build the house. I place every piece of wood and hardware in the drawing. The wood and steel members that I use are components. I make copies of the components when I do the drafting to speed up my drafting process. I then group sections of walls into groups, and make cultists and material orders off of those grouped walls.
I then have to manually assign a piece number for every piece of wood. For example in Wall 20, I number the Studs 1-10. So the piece number is W20S1,W20S2, ect.

As far as the labeling goes the wall number is always first. Followed by:
P - Plate
B - Beam
S - Studs
BL - Block
H - Hardware

Then the number of the paticular item.

I need a plug-in/Ruby Script that will make all the components unique. Then I want to be able to automatically, or manually but easily, number the pieces. Then when i generate the report on the wall i will be able to see all the piece numbers and their respective length
