PTC Creo ModelCHECK Teacher: Start Part and Start Assembly Items
Start part and start assembly items are a group of features that your company has set as a standard starting point for every part and assembly. These features are normally added to the model when it is created, and can be automated with the help of a map key or a menu pick in Creo Parametric.
Start features can be any of the following:
Datum Planes
Datum Coordinate Systems
Datum Axes
Datum Points
Datum Curves
Parameters
Layers
Views
In many cases, you will have different requirements for your start features depending on the type of model you are creating, or whether it is a part or assembly.
Using Start Features has many advantages including:
It makes it easier for other users to understand your model.
It makes it easier for you to assemble parts together because assembly references can be identified in a standard manner.
Maintaining company wide consistency.
Ensures that default datum planes are always used.
