# system command

Syntax

extrude set system keyword ...

Primary keywords:

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.
