(B01_07) Linear Edge Data
Set the linear edges which form the shape of a component.
Applicable Components: Deform (Complex)
(1) It is required to enter parameters (parameters described in "(2)" to
"(4)") equivalent to the number of linear edges specified in the "# of
Edges" data box.
Definition of Linear Edges
Define the linear edges in the light of the following points from (a) to
(e).
(a) Linear edges must be defined such that the shape of a compo-
nent is formed from the linear edges which clarify the maximum
outside dimensions of the component.

(b) Up to 6 linear edges (3 to 6) must be specified.
(a) The more edges are defined, the higher accuracy can be expected.
However, longer processing time will be required in proportion to the
specified number of edges.
(b) The figures show the linear edge Nos.

(c) Select linear edges which have interior angles close to 90°, each
formed by a side and the extension of an adjacent side.
At least one edge must be shifted from the other one by 45 to 135° or 225
to 315°

(d) Select linear edges which are 2.0 mm or more in length.
An edge must be perfectly straight without any irregularity.

(e) It is recommended that the parameters related to linear edges be
defined counterclockwise for easier management, starting with "Edge
1".
Example: As for the component shown below, the shadowed edges must
be selected.
Select "1", "2", or "3" (indicated in the figure below) as the last
remaining edge.
Any one of "1", "2", and "3" can be selected, causing no hin-
drance to the recognition.

However, when "1", "2", and "3" have different dimensions in length,
the selection of the longest linear edge will improve the accuracy of
the recognition.
