grade limit within grade limit

Recommended Posts

i thought that it was possible to have a grade limit within another grade limit--i think i have actually done it a few times. however, that doesn't seem to be working. am i remembering incorrectly? was it changed? is it a bug? or am i simply doing something wrong?

thanks for any input.

Both contours are regrading your DTM and effecting each other, but I don't know if it is what you intend.

One way to illustrate

Select the DTM and in OIP> Site Model Settings>3D Display enable the 3d Contours. Then delete the GLs one at a time and update the DTM. Toggle back and forth with the undo/redo to see the differences.

hi, benson.

i sent this to tech support. word is that what i am trying to do--create limited, more detailed area within a larger more general area--is currently not possible with multiple grade limit modifiers. i remembered wrong.

however, similar requests have been made, and they find this reasonable. so, they are passing my request on to the engineers.
