Creating Equations in External Files

You can create equations in a text file and then import them into one or more parts and assemblies.

  1. Open a text file in an application such as Notepad.
  2. Type equations in the same format as used in the Equations dialog box.
    For example, you might define a global variable, base, and define two related dimensions.
    "base" = 20
"D1@Boss-Extrude1" = "base" + 10
"D2@Sketch1" = ("base"*3) + 5
  3. Save the text file.
You can import the text file into one or more parts and assemblies with the Equations dialog box.

The best practice is to give the linked equation file a unique name based on the file that uses it. For example, Comp1Equations.txt.

Do not use the name equations.txt because that is the default system name. Do not share the same linked file with more than one model.
