Creates a GR-Cylinder feature that dynamically builds a circle from the associated points, clouds or geometry.
Cylinder Features report the following criteria:
Diameter. Which is the distance across a cylinder.
Radius. Which is the distance from the cylinder's origin to its edge.
Length. The total length of the measured cylinder along its axis.
Origin X, Y, Z. Which reports the origin point in the current working frame.
Mag XYZ. Reports the absolute distance between the measure and nominal cylinder centers.
I, J, K. Which reports the direction of the cylinder in the working frame.
Projected Angles (Rx from Y, Ry from Z, Rz from X). Report the relative projections of the normal vector onto the corresponding nominal planes.
Angle Between . Which reports the angle between the nominal and measured cylinder.
RMS. Which reports that RMS of the measured cylinder.
Impingement MIN. Minimum distance between the surface of the cylinder and the reference (impingement plane).
Impingement MAX. Maximum distance between the surface of the cylinder and the reference (impingement plane).
Impingement AVG. Average distance between the surface of the cylinder and the reference (impingement plane).
ConstraintsSA offers the ability to perform constrained fits as well as full RMS fits.
Constrained Radius - offers the ability to fit without editing the radius of the cylinder
Constrained to Nominal Geometry Axis - offers the ability to fit the data while holding the nominal axis alignment. This allows the diameter to change but does not allow the axis to move.
Constrained to Nominal Geometry Orientation - offers the ability to fit without rotation. This allows the fit to happen as long as the measured axis does not tilt.
Use Exhaustive Search This selection can be used to use a full search of potential fit solutions.
Align With Nominal The normal vector can also be set dynamically to match the nominal line using the Align with Nominal check box. This ensures the Angle Between value reported is always the smallest possible angle.
3 cardinal points can be built using the GR-Cylinder feature. These include both the origin point, the center point, and a point on the far end of the cylinder.
The impingement plane concept was added to aid in roller alignment applications. The idea being that the reference roller should be set at a given depth relative to a tangent plane set by the two adjacent rollers. The 3 Impingement criteria are computed dynamically to return statistics on these values. This can be used in conjunction with a dynamic tangent plane built between two cylinders.
