Before i-th of segmental arc full-page proof makes in step 201, including procedure below：
Step 2011, two end points for first delivering out i-th of segmental arc full-page proof；
Step 2012, in CAD software by it is corresponding with i-th of segmental arc full-page proof it is described design segmental arc two ends carry out line
Form design straightway；
Step 2013, design point are chosen：It will be inserted in CAD software using computer on the design straightway in step 2012
Enter Q Along ent, a vertical line vertical with the design straightway is done on each Along ent, by the vertical line and institute
The intersection point of design segmental arc is stated as design point；
Step 2014, by the design coordinate of the design point in step 2013 by being delivered after Coordinate Conversion in step 2011
Between two end points of i-th of segmental arc full-page proof, encryption layout point is formed.
