TBLApproximationOptions

Options used to describe how geometry is approximated.

This record cannot be simply zeroed and then passed to functions that accept approximation options. Use TBLApproximationOptions.Default to setup defaults and then alter values you want to change.

Example of using TBLApproximationOptions:

  // Initialize with defaults first.
  var Approx := TBLApproximationOptions.Default;

  // Override values you want to change.
  Ppprox.SimplifyTolerance = 0.02;

  // ... now safely use approximation options in your code ...
