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 an Auto Cone, the Diameter value in the Feature properties area represents the nominal diameter at the location of the cone where you've defined the THEO XYZ 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.
