In v11 there was a DTM command, "Set Border", which allowed one to exclude portions of a site model from the graphic. This allowed having data points outside, say, metes and bounds, but generating a DTM of the property only. That command is no longer present in 12. After speaking with Tech Support, I've been given the following (undocumented) procedure:
--Create class: "DTM-border"
--Draw bounding polyline and set to DTM-border
--Cut
--Click on DTM and 'Edit Group'
--Paste in place
--Exit Group
--Click on 'Update' in the OI Palette
Problem is, the above procedure does not seem to work for me. Does anyone have an alternate approach to cropping out portions of a DTM (other than converting it to a mesh etc.)?
Thanks in advance.
