system command

Syntax

extrude set system keyword ...

Primary keywords:

normal-axis    origin    u-axis    v-axis

Set the coordinate system. These settings affect how extruded object coordinates (u,v,n) map to global coordinates (\(x,y,z\)).

normal-axis v

Set the normal axis v (3D vector). This is the direction of extrusion (perpendicular to 2D local \(x\), \(y\)).

origin v

Set the origin of the extrusion transformation v (3D vector). When extruded, the 2D extrusion coordinate (0,0) is mapped to (\(x,y,z\)) before being rotated into the u,v,n coordinate system.

u-axis v

Set the u-axis (3D vector v). This axis is the direction of \(x\) from the 2D coordinate system when the model is extruded into 3D.

v-axis v

Sets the v-axis (3D vector v). This axis is the direction of \(y\) from the 2D coordinate system when the model is extruded into 3D.
