#### Cylinder Basic Scan - CAD Data Method

The InitVec of the cylinder is calculated based on the first click that is used to calculate the cylinder with this method.

Type:

The Type drop down list of allows the following:

1) IN: A Hole

2) OUT: A Stud

Angle:

The Angle box displays the angle (in degrees to scan) from the Start Point. Both positive angles and negative angles can be used. Positive angles are considered counterclockwise and negative angles are considered clockwise. The CutVec is considered the axis about which the angle rotates. The angle can be over 360 degrees and the scan will continue for more than one revolution.

Example: If you have given an angle of 720 degrees the scan would execute two revolutions.

Diameter:

The Diameter box displays the diameter of the cylinder.

Depth:

The Depth box displays the depth value that is applied against the CutVec direction.

| A - Centroid B - Depth C - CutVec

Example: If the cylinder has a center of 1,1,3, a CutVec of 0,0,1, and a depth of 0.5, the cylinder's center is set to 2.5 during execution.

Pitch:

The Pitch box shows the distance along the CutVec between the Start and End of the scan when it does one complete revolution of 360 degrees. The cylinder's pitch can have a positive or a negative value and when combined with the CutVec and the angle controls the direction of the scan up/down the cylinder axis.

Example: If the cylinder has a CutVec of 0,0,1, a Pitch value of 1.0 and a positive angle of 720, the scan would execute two revolutions and would move up the axis of the cylinder two units from the start point. If, for the same cylinder, a negative pitch is entered, the scan would execute down the axis of the cylinder two units.
