Comparing Parts with the Detailed Method
This task shows you how to compare two versions of a CATPart document with the Detailed Method. The result will be given as areas, made of clouds of points and curves (those curves being the boundaries between identical and different areas), and surfaces.
 

Note that:

  • The result areas are connex but given on a surface level, not on a global one.
  • The curves corresponding to the boundaries of the areas are of two types:
    • exact curves corresponding to face limits,
    • approximate curves, for the other cases. Those curves are not supported by the model faces.
    • Note that some boundaries can be given through non-limited curves.
  • There may be redundant curves in the boundaries, which are not necessarily identical.

  • Internal curves are not considered in the boundary and are not displayed but in some cases, internal curves may appear due to an algorithm limitation:
    • A boundary can be included in a surface or can be a portion of a 'natural ' boundary:

    • The area is shared by 4 faces. The boundary should be:

    • However the result may appear like this:

      where

      is not expected. This curve is a boundary of the surface

      It is not the boundary of the area. It is an internal curve.
