Joggle Formula Table

This topic provides information about joggle formula table.



  • The JoggleFormulaName column is mandatory.
  • The Joggle_ai columns are optional. They correspond to formula coefficients.
    • A literal type length is created if there is a length unit. If not the created literal is of type Real.
    • The number of coefficient columns is free.
  • The JogglexxxFormulaBody columns are optional. you can create columns to define Joggle formulas for Depth, Runout, StartRadius, EndRadius and Clearance. The xxx stand for any of the parameters just mentioned.
  • Some Keywords are defined to be used as Sheet Metal parameters to integrate in formulas:

    • THICKNESS: defined on the Sheet Metal parameters
    • DEFAULTBENDRADIUS: defined on the Sheet Metal parameters
    • DEPTH: defined on the current joggle
    • STARTRADIUS: defined on the current joggle
    • ENDRADIUS: defined on the current joggle
    • CLEARANCE: defined on the current joggle

These Keywords are automatically replaced by the literal parameter when encountered in a formula body.

Warning: Make sure these keywords are written in capital letters.

The application of a formula can also depend on a condition, if the formula body column is replaced by these three columns:

  • Jogglexxx_Condition
  • JogglexxxFormulaBody_Condition
  • JogglexxxFormulaBody_NotCondition

Example with conditions on Depth and Runout parameters



Important: For each xxx_parameter, the JogglexxxFormulaBody column is optional. But if a Jogglexxx_Condition is found, the corresponding JogglexxxFormulaBody_Condition and JogglexxxFormulaBody_NotCondition are mandatory.

With "xxx" standing for Depth, Runout, StartRadius, EndRadius and Clearance parameters.

Warning: An error message dialog box appears to avoid formula creations if:
  • A parameter is present in a formula describing itself:
  • A xxxparameter is present in a yyy_formula because a yyy_parameter is present in a xxx_formula.

If more than one error are detected, the errors are separated by *** in the error message dialog box.

You can also apply a Formula only if the Base feature of the Joggle corresponds to a pre-defined type. To do so, create a column entitled JoggleRunoutFormula On. The allowed values of this column are WEB and FLANGE.

  • If the value of the column is WEB, the formula applies to Joggles whose Base Feature is the Web.
  • If the value of the column is FLANGE, the formula applies to Joggles whose Base Feature is a Surfacic Flange.
  • If the JoggleRunoutFormula On column does not exist, the formula applies to any joggle.

Joggle Formulas in a Thickness Table

You can define the Joggle Formulas in a thickness table by adding a column named JoggleFormula.

In this column you can find external identifiers to locate the design tables describing the joggle formulas.

Illustration



When you select a specific thickness table and select design table in the Joggle Formula box of the Sheetmetal Parameters dialog box, the Joggle Formula dialog box selects a joggle formula that automatically appears since it is defined by the selected row of the thickness table.
