Discuss how you would create the solid model of the given objects.

Question

(1) Create two keypoints in the active coordinate system at 0,0,0 and 10,0,0.
(2) These keypoints will define the axis of rotation.
(3) Create the cross-sectional area shown.

Answer 1

(1) Create two keypoints in the active coordinate system at 0,0,0 and 10,0,0.

(2) These keypoints will define the axis of rotation.

(3) Create the cross-sectional area shown.



Note that you need to create the smaller areas so that you can create the line fillets later. Glue the areas and create the line fillets. Using arbitrary area command, create the fillet areas.



Set the Workplane (WP) settings to 0.25 for snap and spacing; and 0 and 10 for min and max. Turn on the WP.

Using offset by increments command, rotate the WP 90 degrees about the –Y direction. Move the WP in the –Z direction by 5.25. This procedure will make it simpler for us to make the holes later.

Add all areas and sweep about the axis defined by the keypoints created at step 1.



Create a solid cylinder at WPX=0 WPY=4.25 with a radius of 0.5 and –1.5 for depth.

Using WP settings, change the WP coordinate system to Polar. Change the Active Coordinate System to Working Plane.

Copy the newly made solid cylinder 8 times using X-offset = 0, Y-offset = 45 degrees and Z-offset =0.

Subtract the cylinders from the main body.
