Drive dimensions

Drive dimensions can be divided into the following two types:

Dimensions of constraints on variational profiles, which you can add to profiles using the Smart Dimensions command
Dimensions generated upon creation or editing and mating of solids, which are automatically added by the program.

Drive dimensions constitute the framework of the dimension-driven structure of think3 application's solids. It is by modifying them that you can make dimensional changes to the model. They are like other dimensions only in their graphic aspect but their function is completely different.

In addition to Smart Dimensions, here is a list of commands which automatically add driving dimensions to the corresponding solids/features. See the corresponding pages to know more.

Linear Slot/Protrusion	to create Linear Sweep Solids, Slots and Protrusions
Rotational Slot/Protrusion	to create Rotational Sweep Solids, Slots and Protrusions
Pipe Slot/Protrusion	to create Pipe Sweep solids
Hole & Shaft	to create Holes and Shafts
Fillet	to create Fillets
Chamfer	to create Chamfers
Shell	to create Shell
Draft Angle	to add Draft Angles
Pattern	to create Patterns
Mating	Mating tools: Coincident, Parallel, Concentric and Side

You can blank drive dimensions from view or display them using the Show Driving Dimensions and Hide Driving Dimensions commands. While you can add or delete dimensional constraints to profiles as you like, you cannot delete drive dimensions automatically inserted by the program, as they form part of the structure of the model.

The parametric values of driving dimensions can be changed using the Edit Dimension command.
