The length of individual ruler is 90cm.When using, when left outside scale 5 and right outer scale 6 are set on interior scale 1, without drawing
When stretching action, it can meet to draw to the drawing board of A3 sizes；When left outside scale 5 and right outer scale 6, both ends are drawn to the left and right
Stretch a segment distance so that when the length of whole ruler meets the drawing board length of A2 sizes, you can the drawing board of A2 sizes is entered
Row mapping；When both ends are stretched to maximum conduct to the left and right for left outside scale 5 and right outer scale 6 so that the length of whole ruler expires
During the drawing board length of sufficient A1 sizes, you can the drawing board of A1 sizes is mapped.
Mapping illustration is carried out with the drawing board of A1 sizes below：, first will be left outside when being mapped using the present invention
Scale 5 and right outer scale 6 are stretched to maximum conduct in both ends to the left and right, now, the right side of left block 21 and a left side for right baffle-plate 20
End face abuts against, and the left side of right block and the right side of right shell body abut against, and left outside scale 5 and right outer scale 6 are determined
Position, meanwhile, the quarter of 0 graduation mark 2 and the left scale line 2-1 of interior scale 1 high order end of the left extension graduation mark 9 of left outside scale 5
Degree line 2 overlaps, 0 graduation mark 2 and the right graduation mark 2-2 of interior scale 1 low order end of the right extension graduation mark 10 of right outer scale 6
Graduation mark 2 is overlapped, and the graduation mark 2 of whole ruler is accurately connected, and ensures the precision of measurement.It is pulled to maximum conduct
Afterwards, the right-hand member of the left end of left outside scale 5 and right outer scale 6 is pressed on A1 drawing boards by clip 13, afterwards again to left ladder
Shape vanishing point chute 7 and left vanishing point sliding shoe 11 on right trapezoidal vanishing point chute 8 and right vanishing point sliding shoe 12 are according to the needs of mapping
Positioned, i.e. the position of pair determination vanishing point.Vanishing point：Joining caused by the extension line on each bar side of solid figure is referred to,
That is the end point of perspective point.
During positioning, left screw 16 or right screw are in the state of relaxation first, then to left vanishing point sliding shoe 11 and the right side
Vanishing point sliding shoe 12 moves in corresponding left trapezoidal vanishing point chute 7 and right trapezoidal vanishing point chute 8, is moved to predetermined position
Afterwards, by left screw 16 or right screw-driving, left trapezoidal vanishing point chute 7 or the right side are pressed in the end of left screw 16 either right screw
Trapezoidal vanishing point chute 8, so as to set vanishing point.
Left trapezoidal vanishing point chute 7 or right trapezoidal vanishing point chute 8, the as eye-level display in perspective view, can aid in user
Determine horizon position.
Hand draw ring is set as fixed point during mapping, and user carries out stretching movement by hand draw ring.User moves fixed point
Point into perspective view, then the perspective lines of the point can be made along left rubber band 17 or right rubber band.Similarly, it is former according to perspective
Reason, complete perspective view.
