Dimensions in Configurations

You can apply dimension values to selected configurations as follows:
  • In a part document, you can control the dimensions in sketches and in feature definitions.
  • In an assembly document, you can control dimensions that belong to assembly features. This includes mates (angle or distance), assembly feature cuts and holes, and component patterns (spacing or instance count). You can also control the dimensions of a component contained in the assembly (by manual method only).

Manual Methods

You can manually configure dimension values from these dialog boxes:

Equations, Global Variables and Dimensions

Click Equations (Tools toolbar) or Tools > Equations . In the Equations, Global Variables and Dimensions dialog box, click Dimension View . Edit the value of the dimension, click (in the Value field), and click This Configuration, All Configurations, or Specify Configurations.

Modify Configurations

In the graphics area, right-click a dimension and select Configure Dimension. In the Modify Configurations dialog box, edit the value of the dimension for the configurations you want to change.


In the graphics area, double-click the dimension, change the value in the Modify dialog box, and select one of the following (these options are only available if there is more than one configuration in the model):

This Configuration
All Configuration
Specify Configuration

Design Table

You can also control dimensions in a design table.

The column header in a design table for controlling dimensions uses this syntax:

Dimension@Feature or Dimension@Sketchn

For example, the full name for the depth of an extrude feature is D1@Extrude1; the full name for the dimension of the first Distance mate is D1@Distance1. You can assign meaningful names to dimensions in the Dimension PropertyManager, under Primary Value.

The column header is not case sensitive.

In the table body cells, type the value for the dimension. If a cell is left blank, it inherits the current dimension at the time the configuration is created.

  • When you specify values, be sure to use the system of units specified for the model document (click Tools > Options > Document Properties > Units).
  • You can display dimensions that are driven by design tables in a different color. Click Tools > Options > System Options > Colors. In Color scheme settings, select Dimension, Controlled by Design Table and change the color.
