3.4.3 Detail of Contour Calculation
A figure block, a part of a contour, with its end point not determined is
said to be in the pending state. A pending figure block is drawn by
dotted line.
In the pop-up window for inputting contour figure data, more data input
items than required are provided. These data items are used to calculate
the cross point with the immediately preceding pending figure block,
and also calculate the end point. The pending state is then released.
NOTE
10 successive figure blocks can be specified as
pending blocks.
1) LINE
a) When the preceding figure block is not pending
i) Only X is inputted
-> This line is determined as a vertical line.
ii) Only Y is inputted
-> This line is determined as a horizontal line.
iii) A and either X or Y are inputted
-> The end point which is not inputted is calculated.
b) When the preceding figure block specifying an arc is not pending,
and TANGNT is specified.
i) Either X or Y is inputted
-> The angle A is calculated automatically, and an end
point is determined. If neither X nor Y is inputted, this
line will be pending.
