AIM=

Create the 3d model of a wall as shown in Figure. Consider wall thickness as 9”.

Procedure:

• Open Autocad software and open new drawing With imperial units.
• Set the units as engineering and precision as 0'-0''
• Switch the work space to 3D modeling and set the view as South-West isometric.
• Use line tool to create a line, specify the first point of the line as 0,0,0
• Enter the next point of the line @3'4'',0,0
• Enter the following points to create the face profile of the wall.
• @0,0,7' @3',0,0 @0,0,-7' @3',0,0 and @0,0,10'
• Create a line, specify the first point as 0,0,0 and next point @0,0,10'
• Create a reference line to joint the top two end points of the profile.
• Create a line in the z-axis from the mid point of the created reference line at a distance of 2'6''. This is also a reference line.
• Create a line in the left top end point of the line and joint it to the end point of the reference line.
• Follow the same procedure to create a slope line in the other side.
• Erase the two reference line created.
• Use region command.
• Create surface as the created wall face.
• Type 'Region' in the command prompt.
• Select object in the command prompt and select the whole object.
• Switch the visual style to conceptual.
• Extrude the surface at a distance of 9'' in the Y-axis direction.
• Type 'Extrude' in the command prompt.
• Select the surface and enter the extrude distance as 9''
• Change the UCS and check the dimensions by creating dimensions in the model.
• Change to front view.
• Change the UCS select X and specify the rotation angle as 90 deg.
