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.

Methods and system for incremental exploration of design changes in large computer-aided design models

An example augmented reality system includes: obtaining information about an instance of a device; recognizing the instance of the device based on the information; selecting a digital twin for the instance of the device, with the digital twin being unique to the instance of the device; and generating augmented reality content based on the digital twin and an actual graphic of the instance of the device.
