Parametric Dimensions

In SolidWorks, dimensions drive the model geometry; changing dimensions changes the shape of the model. You can relate dimensions to each other in equations.

1. Open a sketch, sketch a rectangle, and dimension the rectangle.

 

2. Modify the dimensions as needed while creating the sketch.

 

3. Extrude a block base feature.

 

4. Complete the feature to close the sketch and show the solid in shaded mode.

 

5. To modify the block, edit the sketch, double-click a dimension and modify the value.

 

6. Exit the sketch to rebuild the solid with the new dimension.

 

Note: You can also use Instant3D to modify model geometry.
