Enter an option [///]:
Calibrates the digitizer with a paper drawing or photograph, creating the tablet transformation, which is the mapping of points from the tablet to the coordinate drawing system. Calibration is digitizing points on the drawing and mapping them to their real coordinates.
Calibration can be performed in model space or paper space. The Cal option turns on Tablet mode in the space in which the tablet is calibrated. When the space is changed, the Cal option turns off Tablet mode.
The points you enter cannot be duplicates. The points need not be the origin on either axis, and you can enter as many points as you like. The more points you enter, the more accurate the drawing will be.
If you enter three or more points, the program computes the transformation in each of the three transformation types (Orthogonal, Affine, and Projective) to determine which best fits the calibration points. If you enter more than four points, computing the best-fitting projective transformation can take a long time. You can cancel the process by pressing Esc.
Only transformation types for which the outcome was Success, Exact, or Canceled are included in this prompt. A projective transformation can be specified even if it was canceled. The program uses the result computed at the time you canceled.
Specifies a transformation equivalent to a perspective projection of one plane in space onto another plane with four calibration points. A projective transformation provides a limited form of what cartographers call rubber sheeting, in which different portions of the tablet surface are stretched by varying amounts. Straight lines map into straight lines. Parallel lines do not necessarily stay parallel.
Reports the outcome of fit for each of the transformation types. If the outcome of fit is not Success or Exact for any of the transformation types, the program reports failure of the entire calibration process and ends the command. The remaining entries in each column are blank unless Outcome of Fit is Success.
Reports the point at which the mapping is least accurate. The residual is the distance between where the point was mapped during transformation and where it would be mapped if the fit were perfect. The distance is given in the current linear units.
Do you want to realign tablet menus? [Yes/No] <N>: Enter y or n or press Enter
Digitize upper-left corner of menu area n: Digitize a point (1)
Digitize lower-left corner of menu area n: Digitize a point (2)
Digitize lower-right corner of menu area n: Digitize a point (3)
The printed menu form must be affixed to the tablet surface, and the requested points must be digitized. The set of three points must form a 90-degree angle. Tablet menu areas can be skewed at any angle.
Do you want to respecify the screen pointing area? [Yes/No] <N>: Enter y or n or press Enter
Digitize lower-left corner of the pointing area: Digitize a point
Digitize upper-right corner of the pointing area: Digitize a point
Do you want to specify the Floating Screen Pointing area? [Yes/No] <N>: Enter y or n or press Enter
Do you want the Floating Screen Area to be the same size as the Fixed Screen Pointing Area? [Yes/No] <Y>: Enter y or n or press Enter
Digitize lower-left corner of the Floating Screen pointing area: Digitize a point
Digitize upper-right corner of the Floating Screen pointing area: Digitize a point
Would you also like to specify a button to toggle the Floating Screen Area? [Yes/No] <N>: Enter y or n or press Enter
Press any non-pick button on the digitizer puck that you wish to designate as the toggle for the Floating Screen Area
