Point List

find the ideal solution, and is the default setting. Use Last Fit As Guess uses the current geometry fit result’s size and orientation as the initial condition for the next fit recalculation. Use Object As Guess allows you to pick existing geometry of the same type to specify the starting condition geometry for the fit algorithm. In this way, you can provide a “hint” as to the resulting orientation of the geometry. If you find that your cylinder, paraboloid, or cone fits are not what you expect, try using this setting to help the algorithm with an initial guess.

The Geometry Fit Point Listing dialog allows you to view individual points and their errors in a geometry fit.

The table contains all points selected for the fit, in addition to their individual deviation from the best-fit geometry. For circles and ellipses, planar and radial component error is displayed as well. To sort the list by a specific attribute (point name, magnitude error, radial error, etc.) click the associated column header. Click it again to sort the list in the opposite direction.

Any point can be excluded from the fit by unchecking its checkbox, and any excluded point can be included again by re-checking the checkbox. Unchecked (excluded) points appear with other excluded points in the list, so it is easy to find all excluded points.

Points that lie outside the specified tolerance in the main dialog are colored red. Points in the intermediate tolerance zones are yellow and blue, and points inside the first tolerance zone have a white back- ground.
