Point 3

Selection for the construction method:

Fix A ﬁxed point is speciﬁed as point 3.

Edge on Line An edge transition is looked for along a search

line. The detected point is speciﬁed as point 3.

Point (ﬁxed or linked) A ﬁxed point is speciﬁed as point 1. It’s also pos-

sible to use a result point from another module as

a coordinate point.

Edge on Line An edge transition is looked for along a search

line. The detected point is speciﬁed as point 1.

Edge on Arc An edge transition is looked for on an arc. The de-

tected point is speciﬁed as point 1.

Segment on Line Segments are looked for along a line. The center

of either the largest or the smallest segment can

be speciﬁed as point 1.

Segment on Arc Segments are looked for on an arc. The center of

either the largest or the smallest segment can be

speciﬁed as point 1.

Segment on Circle

Segments are looked for on a circle. The center of

either the largest or the smallest segment can be

speciﬁed as point 1.
