<p>PURPOSE:To ensure simple and accurate execution of input of the 3-dimensional coordinates by having input of points on a drawing onto a 1st coordinate surface in a 1st step process and then having input of points on the drawing onto a 2nd coordinate surface according to a cursor in a 2nd step process. CONSTITUTION:A 1st coordinate surface XY is first chosen among those three coordinate surfaces XY, ZY and XZ by a stylus 3. Then the position of the styles 3 on a tablet 2a is displayed on a screen 29. The 2-dimensional coordinates and attribute of the data number are produced when a projected pattern is supplied with push of the stylus 3. The projected pattern is displayed on the screen 29. Then the surface ZY is selected. A 1st cursor is displayed at the input points of a 1st stage in the order of data inputs and an input enable area is secured at the periphery of the 1st cursor. Then the stylus 3 is moved and a 2nd cursor is shifted to a designated area of the 1st cursor. The final surface XZ is supplied with push of the stylus 3 for all data number points. Thus an input pattern is obtained to finish input of the 3-dimensional coordinates.</p> |
