  1. Dimensions
  2. Drafting aids

First, define the ‘Control Expression’ with type ‘Number’ which is used to control the visibility of the selected drafting objects.

Control expression can have zero or a nonzero value.

If Control Expression = 0 (Zero value) – Selected Drafting objects becomes invisible.

If Control Expression = 1 (Any nonzero value) – Selected Drafting objects remains visible.

By default, Expression editor (Menu > Tools > Expressions ) is not available in Drafting application.

To change the value of the control expression, either you have to switch to the modeling application to access expressions dialog/editor or you can enable it in the drafting application by setting the ‘Allow Expressions’ option in the Customer Defaults.

File > Utilities > Customer Defaults > Drafting > General/Setup > Miscellaneous tab > Toggle on ‘Allow Expressions’

Enable ‘Allow Expressions’.
