This box is only available for these Auto features: Circle, Cylinder, Sphere, Cone, Polygon
The Diameter box defines the diameter of the feature. In the case of a stud, the diameter box displays the nominal, user supplied value.
For a cone, this value represents the nominal diameter at the end of the cone where you've defined the X,Y, and Z location.
For a polygon, the diameter is the distance between two opposing sides of even-sided polygons. For other polygons, such as an equilateral triangle, it is twice the radius of the largest circle you can inscribe inside the polygon.
To change the feature's diameter:
Select the existing value.
Type a new value.
Once the feature is created, PC-DMIS updates the size of the feature in the Graphic Display window.
