When I do crude site plan for the houses I design.
I also do some drawing for an engineer that includes some very limited site work. It's fun exploring outside your own box.

The bolts are for drawings I am doing for the engineer, very small bridges, metal parts for water treatment plant, etc.
The dynamic blocks will save me some time. I plan on doing a profile view of angle iron with a wipeout next.
The angle Iron block will help a lot, see below. Being able to stretch from both ends.
