Command: TABLET
The Tablet command configures and calibrates a digitizing tablet and toggles tablet mode.
This command requires that Wintab32.dll from Wacom Technology, Corp. be installed on the computer. Download Wintab32.dll from the internet, then place the file in your system directory: C:\Windows\System32.
A digitizing tablet, also called a graphics tablet, a graphics pad or drawing tablet, is a computer input device that allows you to hand-draw images and graphics, similar to the way one draws images with a pencil and paper. In a CAD program a digitizing tablet can be used to trace paper drawings into a drawing file or to launch drawing commands from a digitizing tablet overlay.
To use a digitizing tablet in BricsCAD
In order to prepare BricsCAD for using a digitizing tablet do the following:
Install the appropriate driver for your tablet.
Make sure Wintab32.dll exists in C:\Windows\System32.
Download the tablet overlay and CUI files.
Print the BricsCAD tablet overlay.
Start BricsCAD, then initialize the tablet.
Configure the tablet: part of the tablet surface is used as the menu area, another part as the screen pointing area.
Calibrate the tablet: a calibrated tablet can be used to trace the geometry of a paper drawing or image into a drawing.
To download the tablet overlay and the CUI files
Download the file Tablet.zip.
The ZIP file contains the following files:
overlay.png: an image of the tablet overlay
overlay(A3).pdf: to print the tablet overlay on a A3 paper size.
overlay(cm).dwg: a
DWG in which the overlay.png is
attached as an image.
The drawing contains two layouts to print the overlay using decimal
units.
overlay(inch).dwg: a
DWG in which the overlay.png is
attached as an image.
The drawing contains two layouts to print the overlay using
imperial units.
tablet.cui: a partial cui file to be used with a tablet.
tablet(acadLike).cui: an AutoCAD-like partial cui file to be used with a tablet.
Extract the overlay CUI files to the Support folder of the roamable root folder (see BricsCAD
User Files).
E.g. C:\Users\[user
name]\AppData\Roaming\Bricsys\BricsCAD\V[version
nummer]\en_US\Support\.
Load Tablet.cui as a
partial CUI (see
To load a partial CUI file).
The next time you start BricsCAD, Tablet.cui will be loaded automatically.

NOTES |
Please make sure the overlay.png image file is extracted to the same folder as the DWG's. It might be necessary to repeat the above procedure after upgrading BricsCAD. |
Do one of the following:
Click the TABLET field in the Status Bar.
Press the F4 function key to toggle the tablet mode.
Choose Tablet On or Tablet Off in the Settings menu.
Type tablet in the
command bar, press Enter, then type ON or OFF ;
or
click ON or OFF in the prompt box.
Do one of the following:
Choose Tablet
in the Settings menu, then
choose Configure... in the flyout
menu.
+
Type tablet in the command bar and press Enter.
You are prompted: Tablet:
ON/OFF/CALibrate/ConFiGure/<On>:
a prompt menu displays:
Type cfg in the command bar and press
Enter or choose Configure in the
prompt menu.
You are prompted: Do you want to align the tablet overlay? Yes/No/<No>:
Type Y in the command
bar and press Enter or choose Yes in
the prompt menu.
You are prompted: Digitize upper left corner of the overlay:
Click on the mark in the upper left corner (1) of
the digitizing tablet overlay.
You are prompted: Digitize the lower left corner of the
overlay.
Click on the mark in the lower left corner (2)
of the digitizing tablet
overlay.
You are prompted: Digitize the lower right corner of the
overlay.
Click on the mark in the lower right corner (3)
of the digitizing tablet
overlay.
You are prompted: Digitize the lower left corner of the screen
pointing area:
Click on the mark at position (4) on the of the
digitizing tablet overlay.
You are prompted: Digitize the upper right corner of the screen
pointing area:
Click on the mark at position (5) on the of the
digitizing tablet overlay.
You are prompted: Tablet configured.
To calibrate the digitizing tablet you must specify at least two points. The more additional points you specify, the more accurate the digitizing process. Additional points are particularly recommended when digitizing a non-orthogonal image, such as an aerial photograph.
Do one of the following:
Choose Tablet
in the Settings menu, then
choose Calibrate... in the flyout
menu.
+
Type tablet in the command bar and press Enter.
You are prompted: Tablet:
ON/OFF/CALibrate/ConFiGure/<On>:
a prompt menu displays:
Type cal in the command bar and press
Enter or choose Calibrate in the
prompt menu.
You are prompted: Digitize point #1:
Click a point on the digitizing tablet .
You are prompted: Enter coordinates for point #1:
Do one of the following:
Click a point in the BricsCAD drawing window.
Enter the coordinates (x,y) in the command bar.
You are prompted: Digitize point #2:
Repeat step 3 to specify the following calibration
point.
You are prompted: Digitize point #3 (or ENTER to end):
Do one of the following:
Repeat step 4 to specify an additional calibration
point.
(You can specify up to 10 calibration points).
Press Enter to conclude the calibration
process.
You are prompted:
if 2 calibration points are specified: Tablet calibrated.
if 3 or more than 4 calibration points are specified: Select
transformation type Orthogonal/Affine:
if 4 calibration points are specified: Select transformation type
Orthogonal/Affine/Projective:
Select the transformation type.
Transformation refers to the calculation of the points on the
screen that correspond to points you digitize on the tablet.
Orthogonal (left): To be used with accurate paper drawings. Orthogonal transformation maintains all angles and preserves relative distances. If only two calibration points are specified orthogonal transformation is generated automatically.
Affine (middle): Maintains parallel lines, but not necessarily the angles between intersecting lines.
Projective (right): Does not maintain parallel lines, nor angles.
