The sweep and variable section sweep are quite frequently used ProE option. By using the Pro-E graph feature with the variable section sweep, we can create the cam follower kind of profile, where we have to create the cam surface from the given graph. The Following seven Steps will discuss about the use of Pro-E graph feature in variable section sweep:

You should have a cam displacement diagram graph ready for creating a cam profile. The displacement diagram should then to be used as input for creating the Pro-E graph feature.

For creating the Pro-E graph feature, go to insert>model datum>graph, and you will find the sketcher window appear. Create the graph as below:
Please notice from the graph sketch that, we have kept 100 units as the total distance from start to end of the curve towards “X" direction but the cam will have 360 degree rotation hence each unit of the graph is equivalent to 3.6 degrees of cam rotation. Also, we have kept the start and the end points of the curve at a vertically same height.
Name the graph as “graph1".
