Disclosed herein are various embodiments for an augmented reality interaction, modeling, and annotation system. An embodiment operates by displaying a digital model of an object within an interface of an augmented reality computing system, wherein the model is associated with a first set of dimensions corresponding to a size of the object and a second set of dimensions corresponding to a size of the digital model. A command to resize the digital model to a third set of dimensions different from the second set of dimensions is received from a user. The digital model is resized within the interface in accordance with the third set of dimensions. The resized digital model of the object is displayed in accordance with the third set of dimensions, wherein the first set of dimensions corresponding to the size of the object remains unchanged within the augmented reality computing system.
