C3D 2012 SP4
Win7 Pro
I have a surface that was originally 3D polylines with elevation. I exported it to XML. I imported the XML file into another drawing. The surface appears in the prospector, but the surface style contours, triangles, points do not appear. If you hover over the surface area, a Z elevation is returned by the cursor. I data short cutted the surface into another drawing and it appears fine in that drawing. Why wont the XML surface display in the import drawing? My contour intervals are correct; 1' and 5' and the objects are on in the surface style.
Try turning off level of detail. I find that particular function buggy and interferes with contour display.
