the sloping face of the extrusion for the plane and again Zoom to 1 .
5. With the Circle tool draw fi ve circles as shown in Fig. 17.24.
6. Form a region from the fi ve circles and with Union form a union of the
regions.
7. Extrude the region to a height of − 60 (note the minus) - higher than the
width of the sloping part of the 3D model.
8. Place the model in the ViewCube/Isometric view and subtract the
extruded region from the model.
9. With the Fillet tool, fi llet the upper corners of the slope of the main
