The polygon plates are placed in the X/Y plane of the current coordinate system. The plate thickness direction is in the positive Z direction. You can control the Advance default plate thickness from the Management Tools.

Command line: _AstM4CreatePolyPlate
To create a polygon plate using points
Another way to create a polygon plate is to transform an existing polyline, which does not have to be closed, into a plate.
In this case, the position of the plate is independent of the coordinate system since the plate position is determined by the position of the polyline.
To access the command
Ribbon: Objects > Plates:
Command line: _AstM4CommPline2Plate
To create a polygon plate at a polyline
You can convert any plate to a polyline and you can modify the resulting polyline and convert back to a plate. The plate is created with its initial properties.
