TRY IT: Create a parametric dimension
1 Create a sketch, or open an existing sketch.
2 In the Sketch environment, on the panel bar or on the 2D Sketch panel
toolbar, click the General Dimension tool.
3 Select the sketch geometry you want to dimension, and then drag to a
point to display the dimension.
4 Double-click the dimension to open the Edit Dimension box.
5 Enter a dimension value. You can enter numeric values or the parameter
names associated with other dimensions or equations. Dimensions based
on equations, as shown in the following image, are preceded by the fx:
prefix.
Automatic Dimensions
You can also use the Auto Dimension tool on the panel bar or from the 2D
Sketch panel toolbar to speed up the dimensioning process. You individually
select sketch geometry such as lines, arcs, circles, and vertices and dimensions
and constraints are automatically applied. If you do not individually select
sketch geometry, all undimensioned sketched objects are automatically
dimensioned. The Auto Dimension tool provides a fast and easy way to
dimension sketches in a single step.
You can:
■ Use Auto Dimension to fully dimension and constrain an entire sketch.
■ Identify specific curves or the entire sketch for constraining.
■ Create only dimensions, only constraints, or both.
