 To delete a line, click and drag over the line, release, and press the Delete key.

Step 14: Use Smart Dimension and Add Relation to fully define the geometry. When this step
is complete there should not be any blue lines.

 To input the skateboard dimensions, click the Smart Dimension tool in the Sketch

toolbar or ToolsDimensionsSmart. The mouse cursor changes to a dimension

symbol.

 Click the deck’s horizontal line, drag the mouse, and release. Click again to place the

dimension. An input box will appear. Double click on the number in the input box and

type the correct dimension, which in our case is 24 inches.

 Repeat for the right and left lines and make them 4 inches in length.

 To dimension an angle, click on two lines and SolidWorks will show the angle between

the lines. The angles in our skateboard are 20 degrees. See Figure 3.4. Notice that if

you move the cursor, the angle also moves.

 Even when all lines have been dimensioned, they are still blue. This means that the

sketch is not fully defined. SolidWorks needs more information. In addition to the

dimensions, we must provide the location of the lines. We will do that by making the

sketch symmetric about the origin.
