How to Use Smart Dimension for Angles in SolidWorks

Precise angles are often important for engineering or architectural designs.

The SolidWorks three-dimensional drafting program includes a useful "Smart Dimension" feature. You can use this tool to quickly determine and display the number of degrees between two lines. Once you determine an angle with the Smart Dimension tool, the precise angle displays for future reference. You can also use the tool to adjust the angle, if needed.

Click on the blue "Smart Dimension" button, located on the "Dimensions / Relations" toolbar. Alternately, select the "Tools" menu, and choose "Dimensions" and then "Smart."

Select a line in the SolidWorks sketch for the first part of the angle. The line turns green. Click on a second line in the sketch. SolidWorks calculates the angle between the two lines.

Move the cursor to fine-tune the position of the angle mark. The smart angle follows the pointer. Adjust the cursor to the inside part of the angle to measure the acute angle created by the two lines, or outside the angle to show the obtuse measurement. Click the mouse when you are satisfied with the placement of the angle.

Read the angle measurement displayed in the "Modify" dialog box. If the measurement matches your expectations, click the green check button. If you want to manually adjust the angle between the two lines, enter a value in the "Modify" box and click the check button.
