3d Dynamic blocks

This is something I'd love to see... as the post said

3d Dynamic blocks.

I'd love to be able to make a cylinder ( piping ) and be able to edit the length...

currently I have to add in dynamic blocks for each length of piping I have in a drawing then
do a data extraction so I can get the total length of each size of pipe I have.

it's really a time hog.

in Freestyle? seems like a waste of effort to do anything other than doodling in Freestyle. Cartoonish interfaces /= ease of use! and are not conducive to getting work done.
