Saving a V5 Hyperbola as a V4 Hyperbola

 

This task shows you how to save a CATIA Version 5 Hyperbola as a CATIA Version 4 Hyperbola. A V4 Hyperbola is created if there is a Hyperbola in the CATPart the customer wants to save as model.

The customers, who want to use V5 Parts (with Hyperbola ) in the V4 are all concerned, and the ones who want to transfer their V4 models to the V5 and to transfer the created Part back to the V4 are also interested.

To be correctly transferred and to keep the canonicity of the hyperbola, these conditions (represented in the screen shot below) must be checked:

  • The distance between the center and the vertex must be lower than the double of V4 infinite and higher than the V4 point tolerance

  • Each point of the hyperbola must be in V4 validity domain

  • The surface under the V5 hyperbola must be a plane

  • The hyperbola must have distinct beginning and ending points. A hyperbola degenerated in one point will not be translated with its canonicity.

If one of these conditions is not checked, the transfer will be done, but canonicity will be lost. It means that one hyperbola would be transferred as a generic curve.
