Move two kinds of basic line drawing methods that stroke collimation method and fixed point setting-out method are to use this easy intelligent plotter, it is to move on to the B point after the zero setting of A point that difference is to move the stroke collimation method, get back to the A point from the B strokes and dots again, and fixed point setting-out method needs to calculate earlier mobile number of division, directly points with the finger or gesticulate to the B point from A then.Can choose a kind of during use arbitrarily.
3. measured length, angle setting-out method: in above-mentioned two setting-out methods, by display shown be the mobile number of division of pen on two chis from a bit (A point) to another point (B point), if think to know simultaneously the length and the angle of this point-to-point transmission straight line, can be by " gear shift " key before carrying out the setting-out operation, display promptly demonstrates the length number and the angle number (left side 4 figure places show length number, the right 4 figure place angles of display numbers) of this straight line.Draw the straight line of a known length and angle if desired, method is as follows: earlier pen is moved on on the desired location, then by " gear shift " key, the length of using " left side ", " right side " to adjust the key adjustment left side simultaneously shows numerical value, makes it equal straight length; With " on ", D score adjusts key and adjusts the angle on the right and show numerical value, makes its angle that equals straight line, at last by " execution " key, can be from the A point straight line of a required certain-length and angle that draws.
(6) technique of painting of single-point line (double dotted line and dotted line):
The method of operating of single-point line (double dotted line and dotted line), basic identical with the method for drawing straight line, difference is during except that setting-out the setting-out indication difference, also be in the picture streamlined process, by " gear shift " key, what display showed is the length and the angle number of straight line, and when drawing single-point line (double dotted line and dotted line), what display showed is line segment length and line segment spacing.During operation,,, adjust the demonstration numerical value of the intersegmental distance of right side bearing with upper and lower key with the demonstration numerical value of " left side ", " right side " key adjustment left side bearing segment length by " gear shift " key.Get final product by " execution " key after adjusting.As think the single-point line (double dotted line and dotted line) of picture known length and angle, the input of length and angle needs drawing under the linear operating earlier, adjust the length and the angle of straight line with " measured length, angle setting-out method ", select picture single-point line (double dotted line and dotted line) by function key again, adjust the length and the spacing of line segment at last, can carry out setting-out.
(7) technique of painting of broken line, wave:
Except that function indication difference, identical with the method for operating of drawing straight line, if select the different proportion chi in " ratio " key, broken line, the wave of different sizes can corresponding draw.
(8) technique of painting of ellipse, circle and arc:
Select the oval function of picture by function key, promptly " ellipse " pilot lamp is bright.
1. the ellipse's drawing method of certain angle: at first pen is moved on on the position in the oval center of circle, this moment, the display left side showed long axis of ellipse length numerical value, and the right shows oval minor axis length numerical value.Adjust these two and show that numerical value makes it equal to draw long axis of ellipse number and minor axis number.By " gear shift " key, adjust the demonstration number on the display left side and the right and make its angle number that equals major axis with adjusting key simultaneously, press can the draw ellipse of certain angle of " execution " key at last.
2. draw circle: the length of promptly drawing major axis and minor axis is equal to the ellipse of radius of a circle.
3. draw arc: in drawing oval process, by " gear shift " key, what the display left side showed is the angle of transverse, also is the start angle of circular arc, and what the right showed is the angle at the end of circular arc.Adjust this two angles with the adjustment key, can picture arc (when these two angles equated, what draw promptly was oval).
This instrument can also enroll other programs as required, as drawing particular curves such as involute urve, sinusoidal line.
(9) storage of graphical user and symbol and use:
In drawing, often some figures and the symbol that uses can store earlier, and method is as follows: by " definition " key, make plotting apparatus be in the user definition state earlier, this moment, user's first pilot lamp was bright, and the number one storage element is selected in expression for use.If this moment, the number one storage element was defined (being that existing graphics deposits in), can press " user " key again and select other storage elements.After choosing, can figure that will store or symbol be drawn with the drawing practice of introducing previously, can deposit (can be the content Delete All of this element storage) in by " deletion " key.After finishing,, just can recover former drawing state by " recovery " key.Extract figure or the symbol deposited in if desired, by " user " key, after the storage element pilot lamp of depositing in figure or symbol is bright, by " executions " key can draw the figure of depositing or symbol.After painting,, just can recover former drawing state by " function " key.Use this " user " key, in drawing, can avoid figure or symbol repeatedly repeat draw, improve drawing efficiency.
(10) tracing
By the key of starting to write, ruling pen is fallen on the paper, at this moment move ruling pen with moving the technique of writing, pen promptly drops on one the mobile alignment that draws on the paper, therefore, moves pen by " starting to write " key, can trace designs on paper.
(11) repeat to draw
This intelligent plotter has the function of depositing, and just begins can be deposited with in the instrument to the whole drafting contents that finish from drawing.When by " drawing " key, plotting apparatus can repaint the figure that has drawn one time automatically, and by " deletion " key, the content of depositing then can Delete All.
