"Active Model" refers to a model that is intended to be used as part of a procedure, operation, step or use for accomplishing a goal or objective. An active model may be a model of a biological object such as soft tissue or hard tissue such as a bone, or may be a model of a physical object such as a cut guide, resection guide, instrument, implant, or the like. In certain embodiments, an active model may have different aspects, features, and/or attributes with respect to other models that a modeling design, viewing, modification, and development computer program product may include. For example, in one embodiment an active model may be a model of a three-dimensional solid object while a model that is not an active model may include a surface of an object by have no internal structure or content. |

"Context Model" refers to a model that is included in a view, image, report, representation, and/or modeling computer program product (e.g., Computer Aided Design, CAD, software product) for the purpose of providing context in relation to other models. For example, suppose a view, image, or modeling computer program product includes models of bones of a foot where an osteotomy is to be performed. A relatively small number of models of bones of the foot may receive an osteotomy. Such models of bones may be referred to as active models. Other models bones of the foot may also be included in the view, image, or modeling computer program product to provide context for the active models. These context models provide a context for the active models. |
