site model (20, 1) error

[CS1]

I am using version 11.5.0, when creating a site model (even from as little as 10 3D locis" I recieve the error "a miscellaneous error has occured. (20, 1)"

This may sound strange but sometimes that error can be dismissed by simply re-creating the DTM from Existing or just by trashing the Existing DTM Symbol .

But before you trash anything try:

Select All on the DTM Layer and make sure that you don't have multiple stacked 3d Loci occupying the same coordinates.

That message indicates there is overlapping data.

You may have both 3D polys and 3D loci points on the same layer, which would cause this. Or you may simply have a duplicate set of data on the same layer. This can be done on accident by selecting the group and pressing the Control or Option key.
