You can create angular running dimensions for an arc or circle in a drawing or sketch.
In this example, you create angular running dimensions in a drawing.
To create angular running dimensions:
- Open install_dir\samples\whatsnew\drawings\angular_running_dimension\flange.slddrw.
A flange appears.

- Save the flange model as my_flange.slddrw.
- Close install_dir\samples\whatsnew\drawings\angular_running_dimension\flange.slddrw.
- Click Angular Running Dimension
(Dimensions/Relations toolbar) or .
- In the graphics area, select the center mark of the flange, from which all others will be measured, to be the base (the zero-degree dimension), and click again to place the dimension outside the model.

- Select the vertices or center marks to dimension. As you select each item, the dimension is placed in the view, aligned to the zero-degree dimension.

- Click
to exit the angular running dimension mode.
