Example embodiments provide methods, mediums, and systems for making and evaluating changes to a model. According to example embodiments, checkpoints may be created as a user changes components in the model. The checkpoints may store changed components in the model that have been changed since a previous checkpoint, and a reference (e.g., a pointer) to the previous checkpoint. A user may freely create new checkpoints, revert to previous checkpoints, and select a checkpointed version of the model to be used as an official working version of the model. Upon activating an existing checkpoint, parametric relationships in the model assembly may be automatically updated in order to make components in the model consistent with each other. Thus, the user can readily change the model and evaluate variations of a design, while at the same time saving storage space by avoiding the need to repeatedly save different versions of the model.

A complicated CAD model may include thousands or tens of thousands of parts, each comprising dozens or hundreds of individual features. To reduce memory requirements and regeneration times, the present disclosure features systems and methods for dynamically loading portions of a computer-aided design model on demand. In one embodiment, a CAD application may progressively load portions of a CAD model as needed by a user for a particular design task. This reduces both memory and processing requirements, and creates the potential for a executing a CAD application with access to a complete CAD model on devices with limited resources, such as a laptop, a tablet computer, a smartphone, or any other system.

A flexible object function is for use in conjunction with, or as an element of, a CAD/CAM software application. The flexible object enables the CAD/CAM application to represent an object that can experience variations in its geometry and logical properties for different design occurrences, while maintaining consistent common properties in all of the occurrences. The variations can be driven by the assembly context, or interacting relationships of the specific occurrence with other components or objects.
