To generate a cylinder using surface data:
Click the Surface mode icon ().
Position the mouse pointer either outside or inside the desired cylinder.
Click once on a surface near the cylinder.
The BASICSCAN dialog box (Insert | Scan | Cylinder) displays the center point and diameter from the CAD data of the selected sheet metal cylinder once the third point has been indicated.
If PC-DMIS detects additional mouse clicks, it finds the best cylinder near all of the hits.
The CutVec is the cylinder axis.
The InitVec of the cylinder is calculated based on the first click.
The angle is calculated as the angle of the arc from the first click to the last click.
