Problems with the Create Planar Pad from Grade Limits are discussed in this previous thread:
https://forum.vectorworks.net/index.php?/topic/111998-creating-a-planar-pad-from-grade-limits-but-planar-pads-without-elevation/
But it went to wider issues, so starting new here. The big fail is that the command creates a pad at seemingly random elevation, instead of at a z value that would balance the cut/fill inside the Grade Limits.
OK, I even suggested moving the DTM up/down to the pad elevation and recreate pads repeatedly to find balanced cut/fill then move entire assembly back to original z.
Sorta works but fraught.
I find now that a different command controls the pad elevation in the Pad from Grade Limits:
Create Objects from Shapes > Site Modifier > Pad > set the elevation. Delete that new pad. Create Pad from Grade Limits will now match that elevation. Perhaps others have discovered this already, but offering here for the brain trust to pick at. Might help with fixing the bug. Video and file attached.
Note: Pad via Objects from Shapes defaults to elevation 0, which explains why many tests of the Pad from Grade Limits creates a pad at z = 0.
