I am attempting to build a topo model using imported contour lines from CAD.
The model is made of four separate groupings of contours. I pre-cleaned the contours in CAD before bringing them into Sketchup.
The four groupings need to align so that we can easily swap the central largest grouping out with various alternatives.
The largest central grouping draped without issue. The smaller groupings however, are showing sharp peaks and valleys rather than a smooth landscape. The file is attached. Any advice would be greatly appreciated Sketchup - Maximum Fill Conditions.skp (7.0 MB)
