Use L-Ext to create an extruded L-shaped object.

Example of L-Ext
Procedure
To create an L-Ext object:
- From the Create menu, choose Extended Primitives
L-Ext.
- Drag the mouse to define the base. (Press Ctrl to constrain the base to a square.)
- Release the mouse and move it vertically to define the height of the L-extrusion.
- Click, and then move the mouse vertically to define the thickness or width of the walls of the L-extrusion.
- Click to finish the L-extrusion.
Interface
Creation Method rollout
- Corners
-
Draws the object from corner to corner. You can change the center location by moving the mouse.
- Center
-
Draws the object from the center out.
Parameters rollout

- Side/Front Length
-
Specify the lengths of each "leg" of the L.
- Side/Front Width
-
Specify the widths of each "leg" of the L.
- Height
-
Specifies the height of the object.
- Side/Front Segs
-
Specify the number of segments for a specific "leg" of the object.
- Width/Height Segs
-
Specify the number of segments for the overall width and height.
Note: The object's dimensions (Back, Side, Front) are labeled as though it were created in the Top or Perspective viewports, and seen from the front in world space. - Generate Mapping Coords
-
Sets up the required coordinates for applying mapped materials to the object. Default=on.
- Real-World Map Size
-
Controls the scaling method used for texture mapped materials that are applied to the object. The scaling values are controlled by the Use Real-World Scale settings found in the applied material's Coordinates rollout. Default=off.
