I am experiencing the following problems when trying to create a DTM.
1) Sides on a DTM
I have applied the step by step procedure suggested by David T on 01/18/2000
However, when performing step 3, the generated 3D loci are offset from the original hull perimeter,
therefore the paste in place command (step 4) pastes onto the 3D DTM layer loci which are offset by a
considerable amount.
As a result, connecting them to the other pasted loci (step 6) appears to be wrong.
2) Cut and fill DTM
I set the same boundaries to two different models and made sure that one of the two models was totally
enclosed (in plan projection) by the other. Why does the program keeps saying that
"the 'to' DTM must be totally enclosed by, or have the same border as, the 'from' DTM" ?
3) I found 'floating 3D symbols' rather puzzling.
No matter how many symbols I insert the 'float 3D objects' will snap to the DTM surface just some of
them, not all!!!
When performing the command again it will swap objects, the result being that the ones which had
been left at the base of the layer eventually float while the others are snapped to the base elevation.
Many thanks
