Circle constructions
Circles can be constructed from:
• Points • Slots • Blobs
• Lines • Distances
• Circles • Arcs
Circle constructed from a circle
A duplicate feature can be useful when it becomes desirable to perform new
operations with the circle while retaining the original feature. Select the de-
sired circle feature, click Measure Circle and then click OK. The new circle
feature will be constructed and will be shown in the Features template, Part
View window and Results window.
Circle constructed from three features
An ideal circle feature can be constructed from three parent features. The
three parent features can be any combination of points, slots, arcs, circles and
blobs. The center points of the three parent features will be used to construct
the new circle feature. Select the desired features, click Measure Circle and
then click OK. The new circle feature will be constructed and will be shown
in the Features template, Part View window and Results window.
Circle constructed from more than three features
A circle feature can be constructed from any number of parent features. The
parent features can be any combination of points, slots, arcs and circles and
blobs. The center points of the parent features will be used to construct the
new circle feature. When more than three parent features are used, the circle
can be constructed using the fitting algorithm of the user’s choice. Select the
desired features, click Measure Circle and then click OK. The new circle
feature will be constructed and will be shown in the Features template, Part
View window and Results window. Right-click the Results window to select
a different fitting algorithm for the data.
