Create mathematical relations between model dimensions or other model
properties using dimension or property names as variables. When using
equations in an assembly, you can set equations between parts, between
a part and a sub-assembly, with mating dimensions, and so on.
You can use the following as
variables in equations:
use any supported operators,
functions, or constants.
To create or modify equations:
the Equations dialog box by doing
one of the following:
in the FeatureManager design tree, and select Add
Equation, Edit Equation,
or Delete Equation.
are listed in the dialog box.
dialog box, choose from the following:
Click to create a new equation.
Click to edit the selected equation.
All. Click to edit all the equations, in a list format.
Delete. Click to delete the selected
Configs. Click to specify the configurations
to which the selected equation applies.
Angular Equations Units. Select one
of the following:
The Equations folder appears in the FeatureManager design tree.
Click Rebuild (Standard toolbar)
or Edit, Rebuild
to update the model.
All equations are solved before the geometry regenerates.
In the Equations dialog box, equations are
listed with information in the following fields:
- The equation is active.

Equation. Displays the equations. Equations
are solved left to right (that is, the dimension on the left is driven
by the value on the right), in the order in which they appear in the equation
Evaluates To. Displays the solutions
of the equations. An icon indicates the status of each equation:
- Solved. The equation
solves without errors.
- Not Solved. Occurs
when you delete a feature or dimension that is used in the equation.
- Read Only. Occurs
when you rename an assembly that includes an equation between assembly
- Comment Only. Occurs
when you add a single quote (') at the beginning of an equation, making
the entire equation a comment.
- Linked Variable.
Occurs when the equation is a linked dimension name. Linked dimension
names cannot be edited from the equations dialog. See Shared Values.
