Calibrate the digitizer to the drawing

Enter the LBP of the ship in the appropriate entry field.

Press the Setup Digitizer button. A dialog appears that allows you to calibrate the digitizer. Start by selecting the correct COM Port.

Select the type of digitizer you are using, the current options are:

SummaGraphics’s Parameters

CALCOMP 9100’s Parameters

Then digitize the four corners of your drawing and type in the co-ordinates of the bottom left and top right corners:

1. Use the mouse to select 1 button, and then on the bottom left point of your drawing.

2. Click on 2 button and digitize the top left point of your drawing.

3. Click on 3 button and digitize the bottom right point of your drawing.

4. Click on 4 button and digitize the top right point of your drawing.

5. Now enter the U and V values by double clicking into each box and entering values. For sections drawn to the right of the centerline (usually the forward section) typical values for the lower left point would be U=0.0 and V=0.0. The Top right point may typically be U= 10.0 and V= 14.0. This would give a ship of 10 meters half beam and 14 meters depth.

6. When the calibration data has been entered press Accept to confirm the data and leave the panel.

For sections to the left of the centerline, recalibrate the digitizer. Points 1 and 2 are at the centerline, Points 3 and 4 are at the beam of the Ship. The section will be drawn on right of the centerline on the screen.
