Points Elliptical Layout
If greater control is required an option to use an Elliptical Layout is also available. This function will layout points in an ellipse in the XY plane of the working frame and offer the following controls:
-
Major semi-axis. The major radius of the ellipse to use for the layout
-
Minor semi-axis. The minor radius of the ellipse to use for the layout
-
Start angle (deg., relative to X axis). Defines the starting location for the first point in the layout, again relative to the current working frame and referencing the X axis position.
-
Number of points on ellipse. Defines the total number of points to build.
-
Add offset to the points. This will both add points offsets and offset the points as if they were being used to measure the specified ellipse:
-
Radial offset (negative is inward). The radial shift value and the radial offset value to include in the points
-
Planar offset (negative is -Z). The vertical shift value and the planar offset value to include in the points.
-
Measurement noise (one-sigma). Measurement noise can be added to create a data set that is more representative of a measure point set.
-
Choose between the two layout methods:
-
Evenly space points around entire ellipse. Points will be equally distributed.
-
Space points by [ ] deg. this option will space the points by the specified degree and it is up to the user to select an appropriate number of points to cover the entire ellipse.
-
Point Naming. Points will be named using a numerical suffix stating with the first point name.
-
Create Center Point Check Box. This will build an additional point at the center of the ellipse.
-
Create Focal Points Check Box. This option will build two additional points at the ellipse focal points.
