• Change the UCS to UCS world.
• Continue creating the line @0,0,6'' @1',0,0 and 0,0,-6
• Change the UCS, type 'UCS' in the command prompt and select Z-axis.
• Specify point om positive protion of Z-axis as the negative side of the Z-axis.
• Create line by specify the first point at the last point of the line created and enter the next point @3<0,3

• Change the UCS to UCS world.
• Create line at the first point as the last created line last point and next point @0,0,-1'3''
• Change the UCS by typics 'UCS' in the command prompt.
• Select X and enter the rotation angle as 90 deg.
• Continue creating line next point @6<0,6

• Change the UCS to UCS world.
• Continue creating the line enter the next point @0,0,6 and @-1'-6'',0,0
• Chamfer the created face at the bottom sides both corners at the first and second distance 1''
• Type 'chamfer' in the command prompt.
• Select the multiple option to create the chamfer.
• Use region command select the whole object created and create the surface.
• Change the visual style as conceptual.

• Extrude teh surface towards the Y-Axis at a distance of 10'
