Direct Input of Equations

For many features, you can enter and modify equations directly in PropertyManager fields that allow numerical inputs. You can create equations with global variables, functions, and file properties without accessing the Equations, Global Variables and Dimensions dialog box.

The following table lists where this capability is available:
Part Features Assembly Features
Extruded Boss/Base Extruded Cut
Extruded Cut Revolved Cut
Simple Hole Fillet
Revolved Boss/Base Chamfer
Revolved Cut Hole
Fillet Linear Pattern
Chamfer Circular Pattern
Base Flange  
Edge Flange  
Linear Pattern  
Circular Pattern  
Curve Driven Pattern  
Extruded Surface  
Revolved Surface  
Fillet Surface  
For example, in the PropertyManager for the Extruded Boss/Base feature, you can enter equations in:
  • Depth fields for Direction 1 and Direction 2
  • Draft fields for Direction 1 and Direction 2
  • Thickness fields for a Thin Feature with two direction types
  • Offset Distance field

To create an equation in a numeric input field, start by entering = (equal sign). A drop-down list displays options for global variables, functions, and file properties.

Numeric input fields that contain equations can display either the equation itself or its evaluated value. You can toggle between the equation and the value by clicking the Equations OTTool_Equations_Tools.gif or Global Variable global_variable_button button that appears at the beginning of the field.

You cannot change an evaluated value when it is displayed in the input field, but you can toggle to the equation and then edit or delete the equation.

Equations that you create or edit in the PropertyManager, Equations dialog box, or Modify dialog box are reflected in all that areas.
