You can use formulas in your shape definition to conditionally display and/or repeat a geometry or sub-shape description.

You can apply formulas to field values in your shape definitions to make the values change dynamically with data. Documentation for the Lucid formula system can be found online on Lucid's help site Use formulas in Lucidchart or in the internal documentation.

In the custom shape format, formula expressions always start with =, such as in the example: =1 + 2.
