Sometimes you need to add a SOLIDWORKS Arc Length Dimension. This can be done in both Sketch and Drawing environments. The Smart Dimension tool, with the correct selections, is used to create a SOLIDWORKS Arc Dimension.
Arc Dimension in a Sketch
Within the Sketch environment, the order of selections doesn’t actually matter. As long as you select the arc and the two end points, the smart dimension tool will create the Arc Length Dimension. It doesn’t matter if you select the two points first and then the arc, or the arc first and then the two points, or even one end point and the arc and the last end point.
Arc Dimension in a Drawing
However in the Drawing environment you’ll notice the order of selections is actually important. You’ll need to select the two endpoints first and then select the arc.
Adjusting the Leaders
The Leader Style can also be adjusted. Typically the leaders will be parallel to each other (due to “Automatically choose arc length leaders”). This can be changed to radial leaders within the PropertyManager Leaders tab.
