MicroSpeed ADI Driver Device for AutoCAD
----------------------------------------
Overview
--------
This document describes the installation and use of a FastTRAP
pointing device driver developed by MicroSpeed for use with
AutoCAD by Autodesk. The driver is usable with all releases of
AutoCAD which support the Autodesk defined ADI (AutoCAD Device
Interface) and allows AutoCAD users to significantly simplify
their use of AutoCAD.
Installation
------------
The basic installation process is as follows:
1. Make sure FastTRAP driver is properly installed
2. Install AutoCAD for an ADI digitizer
3. Install the FastTRAP ADI driver prior to running
AutoCAD
The FastTRAP ADI driver file name is DGTRAP.COM. As with all ADI
device drivers, DGTRAP is a terminate and stay resident (TSR)
program which provides a standardized interface between AutoCAD
and a device specific software driver, in this case MicroSpeed's
MAP.SYS or MAP.COM multi-axis pointer driver. The MAP driver
should be installed for the system as described in Section 3 of
the FastTRAP user's manual prior to installing the DGTRAP.COM
driver.
Prior to using the FastTRAP ADI driver you must install AutoCAD's
digitizer to handle an ADI digitizing device. This is done as
follows:
1. Select option 5 on the AutoCAD main menu
("Configure AutoCAD")
2. Select option 4 on the configuration menu
("Configure digitizer"). A list of available
digitizers will be displayed.
3. Select "ADI digitizer" from the list of available
digitizers. (If your AutoCAD device driver library
is not in a hard disk sub-directory you will need
to have your a diskette containing AutoCAD device
drivers available during the installation). Refer
to your AutoCAD documentation for complete
information on installing device drivers.
After AutoCAD device driver installation, when you list the
AutoCAD hardware configuration the digitizer should be shown as
"ADI digitizer".
To install the DGTRAP driver, execute the following command at
the DOS command prompt:
A>DGTRAP <options>
The options, if specified, define how DGTRAP will operate with
AutoCAD. The options are:
Z=MENU Define trackwheel to select menu items
Z=GAIN Define trackwheel to set FastTRAP X-Y
gain
nnn A number from 1 to 100 setting the
FastTRAP X-Y-Z axis gain
The Z=MENU and Z=GAIN options are mutually exclusive - users must
select one or the other. In the event that both options are
specified the last option on the line will be the one that takes
effect.
The nnn option can be specified with either the Z=MENU or Z=GAIN
options by following the selected option with a space and the
desired gain setting. Valid gain settings are specified on a
linear scale from 1 to 100, with 1 being lowest gain and 100
being highest gain. If the nnn option is not specified the gain
is set to a default value of 25.
The default settings for the DGTRAP command is Z=MENU and gain=25
if no options are specified. This is equivalent to the command:
A>DGTRAP Z=MENU 25
Examples:
A>DGTRAP
Set trackwheel for menu select and gain for X-Y-Z axes to 25
A>DGTRAP Z=GAIN
Set trackwheel for gain select with an initial gain setting
for X-Y-Z axes of 25
A>DGTRAP 50
Set trackwheel for menu select and gain for X-Y-Z axes to 50
A>DGTRAP Z=GAIN 50
Set trackwheel for gain select with an initial gain setting
for X-Y-Z axes of 50
NOTE: The DGTRAP driver must be installed prior to running
AutoCAD. You may want to set up a batch file to automatically
load the DGTRAP driver and then load AutoCAD.
OPERATION
---------
The ADI driver utilizes all three of the FastTRAP's input axes
and all three of it's input buttons to give AutoCAD users more
efficient control over commonly used pointing functions, thereby
increasing user productivity. The ADI driver assigns the
FastTRAP's hardware resources as follows:
Trackball: Select pointer position
Trackwheel: Select menu items or set X-Y gain
(see below)
Left button: Pick item
Middle button: Select modifiers menu
Right button: Enter command
The trackwheel function can be defined to either select menu
items or to set the gain of the FastTRAP trackball X-Y axis gain.
For most users the select menu option (the default) will be the
most useful.
The ADI driver functional configuration is optimized to improve
user productivity compared to other commonly used pointing
devices. For example, when using AutoCAD with a conventional two
button mouse all menu items must be selected by first moving the
pointing cursor from the active drawing area to the menu
selection bar and then picking the menu item; selecting modifiers
for the various menu options requires additional picking and
pointing. In many drawing applications the continual cursor
positioning and repositioning significantly increases drawing
time.
Using the new FastTRAP ADI driver, menu items and modifiers can
be selected directly using the trackwheel and the middle button;
there is no longer any requirement that the pointing cursor be
moved from the active drawing area. This reduces the number of
required pointer positioning and repositioning operations with a
subsequent increase in user productivity.
