New Layer
Creates a new layer. Layers allow you to organize related objects into groups that you can pick, display, and edit individually or together.
Set New Layer Options
Layer Start Number
New layers are numbered starting with this value.
Symmetry Plane Origin
Defines the center of the plane of symmetry for this layer. If you turn symmetry display on for this layer, the geometry will be reflected across this plane.
Symmetry Plane Normal
Defines the normal (perpendicular) direction for the symmetry plane. For example, 0.0 0.0 1.0 is a normal pointing up the Z axis, which creates a plane oriented along the X and Y axes.
Tip: Use the Set Symmetry Plane command in a layer’s pop-up menu to set the plane.
