Derivation control in Creo to IFC Exporter

Derivation control having provision to control the amount of tessellation/triangle mesh using following options,

  • Chord Height
  • Angle control

The values of Chord Height and Angle Control in the derivation control section determine the triangle mesh.

Small values of Chord angle and Angle control give a fine mesh (larger file size) whereas larger values yield a coarse mesh (smaller file size).

The chord height value can be (> 0). The angle control values should be between 0.0 and 1.0.

Note: – Fine mesh will be having bigger file size as compared to coarse mesh.
