Working on gaining control of my grading. In generating a model of contours for model homes, I am using contour survey generated in datacad. I create the contour lines using the horizontal polygon, changing the z setting to control elevation. When imported into sketchup, horizontal polygons stacked and set back as you rise on the slope. I use draw-sandbox-from contours and layout the grid that adapts to the height of the polygons. That is pretty good. However, I seem to be getting edges of the polygons in the finished image that includes the triangulation the program generates. Mostly it is below view. However, I am not able to set the original polygon’s active to delete. To explore this, I took a screen save with one section of program generated triangles deleted to make what is below visible. I can not get the select tool to highlight the polygons under. You can see the affect of overlaps in picture.
Tips always appreciated. Thank you.
