Does a Surface Mask perform the way a Boundary would?
I have three streets that enclose an area within a townhouse development. I have an outside boundary enclosing the whole proposed grading surface generated by a network of baselines of a Corridor Model.
Now I am wanting to do my volume calcs and I want to know if the mask that has been turned of for the visual example below is acting as a boundary for the TIN as well or is it just covering the contour lines?
