The Radial dimension is used to show the radius of a circle or arc. As Diameter dimensions are usually used on circles, Radial dimensions are mostly used on arcs. To use the Radial dimension, click on the arc you wish to dimension and drag the dimension text out to wherever you wish to place it. Remember that when AutoCAD does fillets, it creates an arc in between the two lines. As such, Radial dimensions are often used to dimension a fillet. |
