Profile Plot Options

You can use the Profile Plot dialog box to define the parameters that are used to create a Profile Plot.

Select the section that you want to display.

Best Fit Parameters Area

Algorithm list - Select the bestfit math to use to create the plot:

None - No fit is applied.

Least Square Bestfit

Meas Pts to Nom Curve parameter - Points are measured to the nominal curve.

Meas Curve to Nom Pts parameter - The curve is measured to the nominal points.

Fit to middle of tolerance zone check box - If you select this check box, it fits to the middle of the zone based on the zone defined in the nominal file.

Constraints lists

The options in the Rotation list are:

The options in the Translation list are:

Afterwards, a point 75% along the length away from the pivot is chosen, and the rotation around the pivot makes the line segments from the pivot point to the 75% point collinear. This process is very similar to the 2 Point MCL best fit, but the pivot point is not a 5% point; instead, it is the chosen pivot. The chosen pivot may be either a nose/tail point itself, or the center of the smallest radius of the leading/trailing edge.

Fit to zone - This list lets you select a tolerance zone to fit. This option helps to control how the section fits to a tolerance zone (if any).

2 Point from Nose and 2 Points from Tail

LE Percent box - This value provides the location of leading edge "balance" points as a percentage of the length of the MCL. For example, a value of 10 defines a point 10% along the MCL.

TE Percent box - This value provides the location of trailing edge "balance" points as a percentage of the length of the MCL. For example, a value of 90 defines a point 90% along the MCL.

Min Max

Fit to middle of tolerance zone check box - If you select this check box, it fits to the middle of the zone based on the zone defined in the nominal file.

Fit to zone - This option helps to control how the section fits to a tolerance zone (if any).

Curve Options Area

Tolerances Area

These values define the plus and minus tolerances for these options:

Profile - The values for the positive deviation and negative deviation define a tolerance zone. If you select the Fit to middle of tolerance zone check box, it fits to the middle of that zone (if it is defined) instead of fitting to the zone defined in the nominal file. Specifically, if the plus deviation is larger than the minus deviation (the zone has a non-zero size). If the Fit to middle of tolerance zone check box is selected, then it uses that zone instead of the zone defined in the Nominal file.

Twist

Stack X and Stack Y - See also Displacement.

Display Options Area
