Part Modeling

For the 'Worm Gear Shaft' we will review the Revolved Feature previously

learned, the sketch Polygon tool, and a Mid Plane cut.

Revolve Hex cut

7 .1. - In this part we only need to make three features. The first feature will be a

revolved extrusion. Make a new part file using a template in inches and insert a

sketch in the "Front Plane" as shown. It's very important to add the centerline, as

we'll need it to add the diameter dimensions as we did in the previous part. Select

the "Revolved Boss" command to complete the first feature. Rename the feature

'Base'. Notice the three doubled diameter dimensions using the centerline.

In a sketch like this it is better to add the smaller dimensions before the

larger ones. The reason is if the large dimensions are added first, when the

geometry updates, the small features may behave unexpectedly.

Add a "Collinear" relation between the two lines indicated before dimensioning.
