In order to use a parametric modeler like SolidWorks efficiently, you<br />

must consider the design intent before modeling. Design intent is your<br />

plan as to how the model should behave when it is changed. The way in<br />

which the model is created governs how it will be changed. Several<br />

factors contribute to how you capture design intent:<br />

Automatic (sketch) Relations<br />

Based on how geometry is sketched, these relations can provide<br />

common geometric relationships between objects such as parallel,<br />

perpendicular, horizontal, and vertical.<br />

Equations<br />

Used to relate dimensions algebraically, they provide an external way<br />

to force changes.<br />

Added Relations<br />

Added to the model as it is created, relations provide another way to<br />

connect related geometry. Some common relations are concentric,<br />

tangent, coincident, and collinear.<br />

Dimensioning<br />

The way in which a sketch is dimensioned will have an impact upon is<br />

design intent. Add dimensions in a way that reflects how you would<br />

like to change them.<br />

Some examples of different design intent in a sketch are shown below.<br />

A sketch dimensioned like this will keep<br />

the holes 20mm from each end regardless<br />

of how the overall plate width, 100mm,<br />

is changed.<br />

Pre-Release<br />

Do not copy or distribute<br />

Baseline dimensions like this will keep<br />

the holes positioned relative to the left<br />

edge of the plate. The positions of the<br />

holes are not affected by changes in the<br />

overall width of the plate.<br />
