Derive a PCB
Use the Derive PCB tool to derive a PCB from a sketch profile in the active design and use this external sketch instead of the Outline Sketch in the 3D PCB.
In the Design workspace, save the design.
Click Create > Create PCB > Derive PCB.
The Derive PCB dialog displays.
In the Derive PCB dialog, select a sketch profile.
Select origin by clicking a point from the sketch profile.
Select X axis by clicking a sketch line or edge from the sketch profile.
Click Flip X Axis to reverse the direction of the X axis.
Click Flip Z Axis to reverse the direction of the Z axis.
Note: The Y axis is not selected directly, but rather inferred from the X and Z axes.
