Be awesome if all of the build definitions where exposed to the regular autocad properties window. This would allow angle/length to be changed on multiple surfaces at once!
Maybe even the operation build order could be exposed when you have once surface selected?
Move the Contour Interval, Grid Spacing, Analysis Number of Ranges and Precision outside of the style and into the Object Properties. Why you ask?
Firstly you wouldn’t need so many surfaces styles just to change a contour interval.
Secondly you would be able to change all/ or multiple intervals at once without changing the style in the properties box or prospector
