Adding Variables

Define variables to create a parametric model.

A model is parametric when it is created using variable expressions. When a variable expression is modified, any items dependent on that variable are re-evaluated and automatically updated. It is the recommended construction method when creating a model, but not compulsory.

Defined variables are stored as part of the model in the .cfx file.

  1. Open the Create variable dialog using one of the following workflows:
    • On the Construct tab, in the Define group, click the  Variable icon. From the drop-down list, select the  Add variable icon.
    • On the model tree, a right-click context menu is available on Variables. From the drop-down list, select Add variable.

    • On the model tree, click the icon. From the drop-down list, select Add variable.

  2. Create the following variables:
    Name Expression Comment [Optional]
    Width 1 Width of rectangle.
    Length 1 Length of rectangle.
    BottomDepth 1 Bottom depth of flare.
    BottomWidth 1 Bottom width of flare.
    FlareLength 1 Length of flare.
    TopWidth 2 Top width of flare.
    TopDepth 2 Top depth of flare.
    • Click Add to keep the Create variable dialog open and add more variables.
    • Click Create to add a variable and close the Create variable dialog.
