Site model from existing spot elevations

Recommended Posts

Reimport the DWG as 3D and see if there are any 3D points or symbols in the file.  Sometimes there are 3D symbols which you can drop in a 3D locus and then explode the symbol to get a set of 3D points from which to create a site model.


failing that send me a vw file with the levels isolated. I have a script to convert the levels to a ‘survey points file’ as per @E|FA response above.

Alternatively see this thread for a script which will convert text blocks (2D elevation info) into 3D loci (from which you can then create a site model):



I have never used it but having previously very laboriously manually converted an old 2D topo survey into 3D thought it sounded very useful so kept a note of it... Luckily all subsequent surveys have come as 3D point files.
