This is what it looks like in Creo:

HOOPS Exchange supports of Family Tables depends on what data are available in the native Creo file.
Depending on the model, the representation of the family table components can be:

...

Creo import options used	Result
A3DProEFamTabAccelesratorFileOnly
A3DProEFamTabOrUseTessellation
A3DProEFamTabOrUseWireAndGeneric

Flexible components

In Creo, a flexible is a part that can has several states, with a variation of dimension, tolerances or material. For a example, a spring can be represented as a flexible component.

...

Situation	Result
Model saved in Creo
The tessellation is stored in the Creo file
The tessellation is NOT stored in the Creo file m_bFlexCompUseGenericIfNoTess is true
The tessellation is NOT stored in the Creo file m_bFlexCompUseGenericIfNoTess is false

Boolean operations

In CAD software, boolean operations are a way to define geometrical elements by performing unions or intersections or 2 or more sub-elements.

...

• For older versions, only the tessellation generated by Creo will be loaded if available

• If no tessellation is available, the setting m_bBoolOpUseGenericIfNoTess adapts HOOPS Exchange behavior

  • If the value is set to true a generic representation is loaded. It usually corresponds to the base component used edited part without any of the boolean operation

  • If the value is set to false , no representation is loaded. The component won’t be displayed.

Note: if the tessellation is stored in the file, m_bBoolOpUseGenericIfNoTess won’t have any effect.

Recommendations

• When a model has a defect in HOOPS Exchange, we recommend to resave the file in Creo, and if possible in a more recent version of Creo.
  

• We recommend trying to work as much as possible with models more recent than Creo 4 for the best results in HOOPS Exchange. If possible, resave the file in a recent version of Creo to upgrade the model.
