### Constructing a Cast Cone

A cone can be constructed by changing any given feature into a cone. PC-DMIS will construct the cone at the centroid of the input feature. If the input feature is not a cone, PC-DMIS will use a default value for the included angle. If the input feature is not a line element (line, cylinder, or slot), PC-DMIS will use a default length for the axis length.

You can change the size of the cone; this changes the cone from DEPENDENT to INDEPENDENT. This means that when the cone is executed that the size will not change based on the input feature, but will be independent of the input feature, while the position and vector remain dependent on the input feature. This allows you to have control over the cone's size in cases where the input feature doesn't really have a size, such as a point. The DEPENDENT/INDEPENDENT field is a toggle field that you may change.

PC-DMIS will use the new attributes for all calculations (for example, if the half angle is changed) instead of the default values as described above.

To construct a Cast Cone:

1. Access the Construct Cone dialog box (Insert | Feature | Constructed | Cone).

2. Select the Cast option.

3. Select one feature of any type.

4. Click the Create button.

The Edit window command line for this option would read:
CONSTR/CONE,CAST,feat_1, (DEPENDENT | INDEPENDENT)
