Why should I use a Design-Set?

Use a Design-Set to edit a number of dimensions and parameters in one place - in the Design-Set dialog.

Typically, add to a Design-Set those dimensions and parameters that you believe to be important to the outcome of a design objective. Different Design Sets can be used for different purposes. For example: add those dimensions that influence the Pressure-Angle of a Cam.

When dimensions are in a Design-Set, you can ONLY edit them in the Design-Set dialog, and not model.

A Design-Set can remind you and/or instruct other engineers which dimensions and parameters you should edit, or the opposite, those you should not edit. Give the Design-Set the name/caption - e.g. rename the Design-Set to “Do Not Edit!”.

To show names of Function-Blocks a caption, see Application-Settings > Graphics tab > Display Options | Show Function-Block names.

STEP 2: Open the Design-Set dialog

1.Double-click the Design-Set FB in the graphics-area or Assembly-Tree.

See How to open a dialog

Double-click the Design-Set

The Design-Set dialog is now open.

STEP 3: See Design-Set dialog

Notes :

When you add a dimension to a Design-Set, you can edit the dimension only in the Design-Set.

The dimension-lines and extension lines of a Dimension that you add to the Design-Set are gray in the Part-Editor.

MD-MotDimFB-DesignSet

A Motion-Dimension FB is gray if you add the Base-Value parameter of the Motion-Dimension to a Design-Set.

After you add the Base-Value to the Design-Set, the Motion-Dimension FB has a small icon at its bottom, right corner - see image.
