<%@LANGUAGE="JAVASCRIPT" CODEPAGE="1252"%> FEATURE BASE SHAFT

DESIGN FOR MANUFACTURING

The idea of feature based modeling is simple and allows for easy editing of any feature at any time in the future. It also let's the programmers modify different diameters and bearing surfaces at will.

Another advantage is having a model that looks as if it came right off the lathe after completing the first operation.(see below). As mentioned in the shaft model, when this stage is reached you begin sketching from the left hand face. This mimics turning the part around in the lathe, and starting the second (and last) operation before finish.
Now a picture of this can be used in the routing of a part and the craftsman knows right away if the part is at the correct stage of manufacturing. All of our masters will be done like this soon so if you copy with refs even the draftsmen will enjoy the benefits of feature base modeling.

If you would rather use the one sketch method (above) you still can, but use the share sketch so all the features can be isolated. The results are the same, and now every journal on the shaft can be edited.

Hopefully you will see that we are not being picky, just thinking of the others who will have to use these models long after we are done with them. If I were making the shaft (above) to go in a spaceship, the entire sketch could be used. That is because it would be for looks only and never manufactured.
