Entering Equations
The Add/Edit
Equation dialog box looks like a calculator keypad. Buttons
on the keypad represent all supported operators, functions, and constants.
You can expand and collapse the dialog box.
To populate
the equation box, do any of the following:
Keep the following in mind as you enter equations:
Equations are solved left to right (that is, the
dimension on the left is driven by the value on the right).
Dimension names must be in the form "<dimension_name>@<feature_name>"
or "<dimension_name>@<sketch_name>". Dimension names
must be enclosed in quotes.
Examples:
"D1@Base-Extrude"
"D5@Sketch2@crank-knob.Part"
When you enter a dimension name by clicking
the dimension in the graphics area, the required quotes are automatically
inserted. When you enter a dimension name by typing, you must type the
quotes.
You cannot specify units of measure in equations.
Equations use the units specified in Tools,
Options, Document
Properties, Units.
For example, if the document length units are inches,
then in the equation "D3@Sketch2"
= "D2@Sketch2" +1, the 1
in the equation represents one inch. If you change the document length
units to millimeters, the 1 now represents one millimeter.
You can add comments to equations to document
your design intent. Click Comment
or type a single quote (‘) at
the end of the equation, then enter the comment. Anything after the single
quote is ignored when the equation is solved.
Example:
"D2@Sketch1"
= "D1@Sketch1" / 2 ‘ height is 1/2 width
