- If the Edit Dimension option is enabled, the Edit Dimension box is displayed. Specify a value, use an equation to calculate the value, or click the arrow to measure the value, show dimensions, or set a tolerance.
Tip: You can also enter or edit an expression that defines a parameter. For example, enter HGHT = 5mm. The expression is parsed to create the parameter HGHT and assign it a value of 5 mm.
- Continue selecting geometry to create dimensions or right-click then select OK to end the command.
Note: If the dimension overconstrains the sketch, you can accept it or cancel the dimension. If you accept the dimension, it is saved as a
driven dimension
. Driven dimensions are displayed in parenthesis and cannot be edited.
