![]() Hence, if you do not have an electronic file with the Surveyed data, you are not in a very good situation. To my knowledge Google Earth was the only public mapping engine providing Topographic data for free.You first mentioned that you need contour line and now you state MASS Massing of a site is a totally different play.Cesium does not support topographic contour lines so it won't work for you.Hey I had no idea Google Earth stopped and is no longer supported by google!

When you already have the contour lines link it up to your revit file and now you can create a topo from this. Particulary the vertices of the 3d polyline which will have the same xyz as per the survey points. It is a tedious task but this is where revit will extract the information necessary to plot the topo element. How I do it is I create a 3d polyline and draw lines connecting the points. ![]() Now revit cannot plot the topo element with just points in cad it needs the 3d polyline contour lines so if I the survey drawings doesn't have contour lines I have to do it manually. the z value determines the eleveation of these points. these are drawings that had points in it that have an xyz value. We take a surveryor's drawing which contains usually just survey points but sometimes also contour lines which is a 3d polyline elements.
