Assembly Design File-based Design Import

This document provides information about the migration of a V5 CATPart containing Assembly Design features, when the FBDI process does not isolate the links, i.e. when the Always deactivated option is selected. See FBDI General.

Also refer to the File-based Design Import User's Guide, it provides global and useful information about the V5/V6 migration process.

Feature Types Version 5 Version 6
Assembly Constraints Assembly Constraints Imported.

All assembly constraints are converted as engineering connections.

Sector in Angle
  • Sector option associated with an angle value is not imported.
  • When the angle value is defined with another sector than Sector 1, the angle value is modified in order to keep instance positions.
  • When the angle value is involved or driven in a formula, a warning message asks user to check the value. This is true only if the formula is imported too, otherwise only the imported angle value is taken into account.
Perpendicular or Parallel Imported.
Point Contact Line Contact Surface Contact Annular Contact Converted as contact.
Knowledge formula (in or out) related to constraints Imported.
Constraints names Not imported.
Fix together with N instances Converted as N-1 engineering connections, couple of instance per couple of instance.
Fix together of Fix together Converted to independent engineering connections of fix together.
Constraint sets Not imported.

Note: Engineering connection groups all constraints related to a given couple of instances, which is the most frequent use of constraint set. So engineering connection can be seen as an automatic and smarted constraint set.

Assembly Symmetry Assembly Symmetry Imported.

Note: Products and parts resulting from the symmetry are imported as result: shape remains associative (as result with links import), product structure and position associativity are lost.

Assembly Pattern Assembly Pattern Imported.

Note: Product instances resulting from the pattern are imported as result: instance count and position associativity are lost.

Geometrical Assembly Features Geometrical Assembly Features Imported.

Operated part instances are imported as result: shapes remain associative (contextual imports).

Miscellaneous Flexible assembly Imported.

Flexibility is declared on the Reference that becomes a PMR (Positional Mechanical Reference), then allowing to declare some of its instances and eventually occurrences as repositionable. Some particular instances of this PMR are declared as repositionable. Once instantiated, the instances of this PMR can have overloaded positions independent from the one defined on the other instances.
Product graphical properties Not imported.
