Use Logic And Formulas

What this is

Logic defines how a block turns inputs into behavior.

It is deterministic and evaluated.

• Variables - computed values
• Formulas - rules that compute values and select behavior
• Lookup tables - data-driven selection used inside formulas
• States - behavior switching using formulas

How logic works

Every block follows this flow:

• Parameters provide input values
• Variables compute derived values using formulas
• Formulas can reference parameters, variables, table lookups, and supported functions
• States use formulas to select which behavior is active
• The final evaluated results drive geometry, nested blocks, and outputs

Where it is

• Definition Tab -> Logic tab: variables and formulas
• Definition Tab -> Tables tab: lookup tables used in formulas
• Definition Tab -> States tab: behavior selection using formulas
• Definition Tab -> Debug tab: resolved values and evaluation results

Visual: Structure -> Computation

Visual: Resolved results

What you can do

• Define variables using formulas
• Use functions (IF, SWITCH, ROUND, SUM, LUT_EXACT, LUT_RANGE)
• Use lookup tables for data-driven decisions
• Control behavior using states with formulas
• Inspect resolved values in Debug

What happens

• Parameters resolve first
• Variables evaluate in dependency order
• Formulas compute values or report errors
• States evaluate formulas to select behavior
• Resolved values are used everywhere (geometry, outputs, nesting)

Key idea

Logic turns inputs into predictable behavior using formulas, variables, tables, and state selection.
