PTC Creo ModelCHECK Teacher: Dimensions
Creo ModelCHECK reports two types of dimensions:
Shown dimensions
Dimensions that are created using the same dimensional constraints as the model
Created dimensions
Dimensions that are created in Drawing Mode.
It is highly recommended that you use as many shown dimensions as possible for the following reasons:
It is faster to detail your drawing this way.
It is more difficult to make mistakes because the same dimensions that were used to constrain the part are used for the drawing.
Dimensions can be modified from the drawing and the changes will be updated in the model.
Created dimensions should only be used in cases where the model does not contain adequate dimensioning scheme for manufacturing.
