Abstract: Managing of constraint-based violations in a Product Data Management (PDM) environment is provided. A method for managing constraint-based violations associated with a product in a PDM system includes obtaining a set of constraints defined for a product from a product database. Constraints that are conflicting with requirement data associated with the product are determined from the set of constraints, and the constraints are grouped into a plurality of logical groups. Each of the logical groups is associated with an independent violation. One or more solutions corresponding to each independent violation are computed based on the logical groups, and conflicts between the constraints and the requirement data corresponding to each independent violation based on the corresponding one or more solutions are resolved.

Abstract: Distributed systems and methods for allowing multiple users at separate workstations to collaboratively create and modify a geometric model of an object. According to embodiments, a system includes program code to generate the geometric model of an object at a first workstation and to store a first data representing the geometric model. The system also includes program code to transmit a duplicate copy and modification commands to a second workstation. The system also includes program code to receive a modified duplicate copy of the first data from the second workstation and to combine the first data and the modified duplicate copy of the first data to generate a modified geometric model of the object.
