Wall+Wall
This command creates a new UCS with 2 clicks at the intersection of the two extracted planes (both on walls).
Requirements
No selection is required to launch the command.
Click the first point on a wall using Define points: a local plane is extracted on this wall.
Click the second point on another wall: a second plane is extracted on the wall.
Notes
The origin of the created UCS is the projection of the first clicked point on the intersection line.
The Z-axis of the created UCS corresponds to the WCS Z-axis.
