RWE, oilburner and other surveyors can calm down. I was not dismissing you. I am just saying that I am not going to keep trying to explain to you why I would write enhancements to a CAD program for my civil engineering needs. I have been writing CAD programs, FEA programs, and add-ons to CAD programs for all sorts of things for 30 years. Just accept the fact that engineers and architects have reasons for doing things before they hand it over to other engineers and surveyors in the field, who don't need to know the about or why of the high-level design. All they need to know is the objective of the construction, so they can work with the design engineers on problems, field changes, schedule changes, etc.
