a polygon shape a polygon shape and place it in and place it in the space; use the space; use the parameter the parameter controls to controls to change the change the overall overall dimensions of dimensions of the shape.the shape.

Step 2- Deselect Step 2- Deselect the object (right the object (right click) then select click) then select faces using quad faces using quad menu (right menu (right click). Select the click). Select the faces in the faces in the perspective view perspective view port; Edit in top, port; Edit in top, front and side front and side views only.views only.

Step 3- Select vertex Step 3- Select vertex and turn on the slice and turn on the slice plane tool to divide the plane tool to divide the geometry. The slice geometry. The slice plane needs to be plane needs to be parallel to the direction parallel to the direction of the slice (x or y). of the slice (x or y). Make sure the slice Make sure the slice plane is highlighted. plane is highlighted. You may have to rotate You may have to rotate the plane by using the the plane by using the rotate option by right rotate option by right clicking the object. clicking the object. Slice the plane. Cut as Slice the plane. Cut as many polygons that are many polygons that are needed. See next slide.needed. See next slide.
