This command, which is available from an assembly, is used for creating a family parameter that can be used when creating components.

Creation Stages / Use:

Select Construction > Parameters > Family Parameter... command from the drop-down menu.

1. Enter a name.

2. Select a family from the drop-down list. The list contains only the families that are used in the assembly document or in open family documents.

3. Validate using .

Modifications / Additional information:

You can edit a parameter from the Parameters folder in the entities tree.

Example of use:

If we are working with a "bolt" assembly, comprised of a screw and a nut, we may want to vary the following elements:

• The screw type (screw family used).

• The screw code (M6 x 20).

• The nut type.

• The nut code.

There are two ways for these choices to be done:

• For each family code, meaning that we clarify that the code "B1" uses a "T1" type and "C1" code screw.

• Using a driver, meaning that the choice will be left to the user of the bolt at the time of inclusion.

For this kind of assembly family, we must first create somewhat special parameters: family parameters and code parameters.

The family parameter will be able to include components whose family will be determined by the value of a parameter.

For a screw, we can create a "sf" parameter corresponding to the screw family. Then, each modification of the parameter will change the family of the included screw.

Once the variable components are included using family and code parameters, it is possible to make an assembly family.

For example, in the case of the bolt, we can image putting the screw's family parameter first (its value will be requested during the inclusion) and the rest in the catalog (the bolt code selection will determine the other variations).
