PTC Creo ModelCHECK Teacher: Unused Models
There are two steps to adding a Creo Parametric model to a drawing. The first is to add it to the drawing and the second is to create a view which displays the model.
Additional models can be added to the drawing by selecting Views, Dwg Models, Add Models. Sometimes a user will inadvertently add more models to the drawing than are required. The problem with this is that the more models a drawing has associated to it, the larger the file size will become. Also, each model associated with a drawing has to be retrieved into memory and regenerated when the drawing is retrieved, which could greatly increase the time it takes to bring drawings into session.
There are two ways to determine what models are added to the drawing. The first is in the Drawing menu and allows you to set the current model (Set Model). The second and more effective way is: Views, Dwg Models which brings you into a menu where you can set the current model, add new ones, or delete unwanted ones.
There are times when it is necessary to add a model to a drawing and not display it. An example of this is when a model is needed for parameter information, but is not needed in a view.
