Editing feature point filtration
Point filtration extracts aberrant data points from
the total population of points during the least squares best fit cal-
culations of arc, circle and line features. Points are extracted when
they exceed the specified error limit (Quantization factor) and fall
outside the specified standard deviation range (Sigma factor). The
filtration process ends when all remaining data points satisfy the
quantization or standard deviation requirement, or when the Pro-
portional Factor set in the Tools/Options/Point Filtration screen is
reached.
Extracted data points are shown in the Feature Stamp window in
yellow. The last points retained are shown in red.
NOTE
The default colors of data points can be changed in the Color Custom screen of the
Tools menu.
