#### Circle Basic Scan - Wire frame Data Method

Wire frame CAD data can also be used to generate a circular scan.

To generate the circle:

1. Click near the desired wire on the circle. PC-DMIS will highlight the selected wire.

2. Verify that the correct feature has been selected.

The dialog box will display the value of the selected circle's center point and diameter once the wire has been indicated.

Note: If the underlying CAD element is not a circle or arc, additional clicks may be necessary to identify the feature. If PC-DMIS doesn't highlight the correct feature, try clicking on at least two additional points near the circle.

- CutVec: This vector is the axis of the circle and is the plane in which the scanning will be done.

- InitVec: This vector describes direction in which the probe will take its first hit to start the scan. This vector is calculated according to the mode of data entry. This vector and the CutVec are normal to each other.
