That's what I'll be doing for the time being. However I'm trying to eliminate AP from the equation. It means maintaining 2 separate files & that's always an added QA issue.
Site tools in AP are very comprehensive.
Insert spot levels.
Calculates contours & inserts the text label.
Creates a mesh surface
Does cut & fill to a user nominated RL (with quantities of cut & fill automagically calculated)
I just hope all these functions are available in Env Real Soon Now
/later I'll be spewing if v4 still can't handle importing text & attributes in dwg files. In AP the user can attach a comment to each spot level which comes in very handy when plotting paths, drains, retaining walls etc.
If not it means I'll have to plot the dwg as well before tracing over in Env.
