Let us imagine a design objective: Improve the pressure angle between a cam and a cam-follower roller.
Without a Design-Set you must:
1.Edit a Part...edit a dimension...close the Part-Editor...
2.Review the design objective - has it improved?
3.Edit a FB...edit a parameter...close the FB dialog-box...
4.Review the design objective - has it improved?
Repeat 1 to 4 again, and again, and again, ...
With a Design-Set you can:
1.Add to the Design-Set all of those dimensions and parameters that you believe can improve or influence the design objective.
2.Edit, within one Design-Set dialog-box, the dimensions and parameters
3.Watch the design objective continuously change (in a Graph FB) at the same time as you edit the dimensions and parameters in the one Design-Set dialog-box
The Power of a Design-Set:
1.The effect on a design objective as you edit dimensions and parameters is immediate, and...
2.... the sensitivity of the design objective to each dimension and parameter is much easier to understand
3.... it is very convenient.
It is much easier for you, and others who may need to edit the model in the future.
Open the model from Tutorial 6A.1
Save the model as 7-A
What is the Design Objective?
The design objectives are:
1.The Pressure Angle must be less than ±30º
2.The radius must be less than 100mm but more than 50mm
3.The position of the Cam-Shaft can move within Minimum and Maximum Limits.
