Materials List Revisited

[MPDesign]

I wonder if we can do a macro that reads a line length and calculates the materials from it because of the formula in the macro?
I also have avoided the materials listing feature and been of the opinion that it does a good job on surface calcs if you material is defined/sized correctly.
I don't do estimating as a service. if i did would use the unit & assembley cost estimating approach.
