Sketchup make here. I have made a simple rectangle into a contour with some peaks & troughs. I want to divide it into equal segments so I can take lines in section. I have attached a photo of the finished piece I am trying to replicate (similar anyway). So I need to take a series of straight lines, equidistant, from the contour field, and give them all the other three sides, and some depth, so I can make a plywood cutting guide for each of the segments.
I can do a section plane to get me to the point I want the line to cut, but it doesn't create something I can select and work with. Thanks
