I've just created my first set of 'proper' dynamic blocks (i.e. not just changing visibility states) of pile caps.
Each block has 2 visibility states, plan & elevation and pile sizes range from 200mm dia to 600mm dia in 50mm increments. The cap depth ranges from 700mm to 1m and the pile inset from 75mm to 125mm into the cap.
The 3 pile cap took forever to get working, but I got there eventually.
NOTE: NOW UPDATED TO INCLUDE REFERENCES & DYNAMIC CO-ORDINATES FOR THE PILE CENTRES..
