Sketch Dimensions
You can create features without adding dimensions to sketches. However,
it is good practice to dimension sketches.
Dimension in accordance with the model's design intent; for example,
you might want to dimension holes a certain distance from an edge, or
else a certain distance from each other.
|
To place a hole a specified distance from
the edges of a block, dimension the diameter of the circle and dimension
the distance between its center and each edge of the block. Circles are
measured from the center by default. |
|
|
To place a hole a specified distance from
another hole, dimension the distance between the centers of the holes.
You can also specify dimensions to the minimum or maximum point on the
circle. |
|
Most dimensions (linear, circular, or angular) can be inserted using
a single tool, Smart Dimension 
on
the Dimensions/Relations toolbar.
Additional dimension tools (Baseline, Ordinate,
Chamfer) are available on the
Dimensions/Relations
toolbar.
You can dimension all entities
in a sketch in one operation with Fully
Define Sketch.
To change dimensions, double-click the dimension and edit the value
in the Modify
dialog box, or drag a sketch entity.
