An apparatus, method, and program product are disclosed for collaborative project modification. One apparatus includes an enabling module that enables a first group of users to modify a first portion of a project in a collaborative environment. The apparatus includes a blocking module that blocks a second portion of the project from being modified by the first group of users. The apparatus includes an updating module that, for the first group of users, conducts immediate updates to the first portion of the project after a user of the first group of users modifies the first portion of the project and conducts deferred updates to the second portion of the project after a user of a second group of users modifies the second portion of the project.

Collaborative project modification

A computer-implemented method for preventing reference invalidation when reversing operations in synchronous collaborative applications may include (i) storing, on a client, a shared model of an engineering object including one or more features, (ii) receiving, from a user, an operation to be performed on the feature, (iii) before performing the operation, storing, in a command stack on the client, information sufficient to restore the feature to a state prior to performing the operation, (iv) receiving, from the user, a request to reverse the operation, (v) determining whether reversing the operation will create an invalid reference due to a conflicting operation having been performed on the feature at a second client, and (vi) in response to determining whether reversing the operation will create an invalid reference, reversing the operation or performing a resolution operation to prevent the reference invalidation. A system corresponding to the above method is also disclosed.

Method for preventing reference invalidation when reversing operations in synchronous collaborative applications

An apparatus, method, and program product are disclosed for collaborative project management. One apparatus includes a selection module that receives a selection by a local user of an information handling device to display an application screen of a remote user of multiple remote users. The application screen of the remote user displays a project used by the multiple remote users in a collaborative environment. The apparatus includes a display module that displays on the information handling device the application screen of the remote user. The application screen of the remote user is updated immediately as modifications to the project are made.
