# system command

Syntax

sketch set system keyword ...

Primary keywords:

Set the coordinate system. These settings affect how extruded object coordinates (u,v,n) map to global coordinates ($$x,y,z$$). Object coordinate (n) and global coordinate ($$z$$) are 3D only.

normal-axis v (3D only)

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 (2D or 3D vector). If extruded (FLAC3D), 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 (2D or 3D vector v). This axis is the direction of $$x$$ from the 2D coordinate system if the model is extruded into 3D (3D only).

v-axis v

Sets the v-axis (2D or 3D vector v). This axis is the direction of $$y$$ from the 2D coordinate system if the model is extruded into 3D (3D only).
