Overview
--------
XCad is an advanced Computer Aided Design (CAD) system enabling two and
three dimensional design, drafting and visualisation of design projects.
It is extremely powerful and versatile, yet easy to use. XCad enables the
creation of two dimensional drawings and/or three dimensional models, of an
almost infinite size and an accuracy to a millionth of a millimetre or inch.
XCad can import and export drawings in a number of formats, including DXF
and IFF. Supplied with XCad are a number of utilities that enable standard
drawing file formats to be converted for use with other programs. These can
be found in the XCad-utils directory and include translators to Postscript,
Sculpt 3D/4D and Aegis formats.
XCad comes in two parts :- XCad 2D, the two dimensional section of the
program and XCad 3D, the three dimensional section of the program. Each
of these are separate programs thus reducing the demands made by XCad on
your system.
There are two different products in the Amiga XCad range. These are XCad
2000 and XCad 3000 and both contain the 2D and the 3D sections of the
program. They differ in the amount of functionality that they provide as
follows :-
XCad 2000 :- This is a low cost entry level CAD product with many of the 2D
drawing features, but limited 3D functionality. XCad 2000 is ideal for the
first time user and for educational applications. Transition to XCad 3000
is painless as both versions have the same look and feel and complete
database compatibility, plus full Autocad DXF file transfer compatibility.
XCad 2000 will run on any type of Amiga computer with at least version 1.2
kickstart and 1 MB of memory. The minimum configuration however that is
recommended is 1.5 Mb of memory, a colour monitor, and any Amiga supported
printer or a HPGL pen plotter.
XCad 3000 :- This is a fully featured CAD product offering the full 2D and
3D features of XCad and is aimed at professional designers, draftsmen or
engineers who want to make the most of the Amigas powerful graphic capability.
XCad 3000 contains over 1000 3D command combinations. It includes point,
line, string, arc, polygon, and patternfill entities with planar surfaces and
surfaces of revolution as standard primitives. Modification commands
include copy, rotate, move, mirror, scale, and project, and location input
features include grid snap, entity snap, origin, intersection, layer, colour
etc. It also includes user defineable construction planes, automatic
perspective views, support for HPGL, CPGL, and BGL pen plotters, and direct
output to Imagine for colour shaded images.
XCad 3000 will run on any type of Amiga computer with at least version 1.2
kickstart and 1.5Mb of memory. The minimum configuration however that is
recommended is 2 Mb of memory, a colour monitor, and any Amiga supported
printer or a HPGL, Calcomp (906/907), DMPL or Oce (BGL) pen plotter.
Installing XCad on your Hard drive
----------------------------------
In order to install XCad merely change to the drive that contains XCad and
enter the command :- EXECUTE HDINSTALL yourdrive:
Where :yourdrive is the harddisk partition where you want to install XCad.
The procedure will ask a number of questions. Unless you are using an NTSC
system then answer yes to the question about running a PAL system. A new
directory will be created on your harddisk and all of the relevant program
files will be copied into it. The installation procedure will also make the
relevant additions to your startup file if required (it will make a copy of
the original file before doing this).
Running XCad
------------
XCad may be run from either the Workbench icon or the CLI.
To start XCad from the Workbench simply double click on the icon in the
normal way. There are several XCad icons and each is labelled to show what
section of the program (2D or 3D), and what screen resolution (Highres or
Medres) and how many colours will be available (8 or 16). Just choose the
one that suits your needs. Both the PAL and NTSC screen displays are
supported.
To start XCad from the CLI, enter the command XCad20003D or XCad30003D to run
the 3D section, or enter XCad2000 or XCad3000 to run the 2D section of the
program.
Entering XCad commands
----------------------
All of the XCad programs accept input in the form of a VERB (what you are
doing) followed by a NOUN (what you are doing it to) and then an identifier
or IDENT (the locational input). There are also optional modifiers which may
be entered with many commands. The command structure is therefore of the
general form:- VERB NOUN [Modifiers] : IDENTS
Examples of Verbs (the doing words) would be DRAW, DELETE, ZOOM, COPY etc.
Examples of Nouns (what to do it with) would be LINE, CIRCLE, ENTITY etc.
Examples of Modifiers (special conditions to apply) would be DIAMETER n,
ANGLE nn, COPY etc.
Examples of IDENTS would be (after the action prompt or :) LOC, END, IX etc.
There are slight differences in syntax between the commands in the XCad 2D
and the XCad 3D modules, but when using the menus this should be relatively
transparent to the user. Examples of XCad commands might be as follows :-
DRaw LIne :
DRaw CIrcle DIAMETER 4 :
DRaw LIne : IX 29.1 IY 150.98 in XCad 2D
DRaw LIne : IXYZ(29.1 150.98 97.2) in XCad 3D
DELete ENTities All
Zoom Window :
You will notice that the first few characters of each command are in upper
case. These are the number of characters that XCad needs to recognise the
command and are in fact all that need be typed if using the keyboard for
input. You may cancel a command that has been partially entered with
<ctrl>C.
The Pull Down Menus (PDM) become visible when the top menu bar is selected
with the right mouse button. This contains the complete XCad command
structure but is not the only menu system available to XCad. User
defineable automenus can be created using the OPEN MENU command, and this
command is also used to activate a Screen menu or Dynamic menu previously
created with the MODMENU command. Tablet menus are also available, if you
have a graphic tablet device, via the command OPEN TABLET.
How the two Sections of XCad work together
------------------------------------------
Often, when creating a complex design in 3D, it is easier to draw at least
part of it in 2D and then bring the drawings into the 3D section of XCad to
be combined and finished. Alternatively, if an isometric view of a object
is require, then the use of a 3D model is the simplest method. The 3D
model, once constructed, can be rotated and viewed from any angle. The view
can then be saved to a file and transferred back into the 2D module.
The database files of XCad 2D and XCad 3D are not interchangeable since they
contain different types of information. The 2D program understands things
such as dimensions and text whereas 3D does not, and 3D understands Z
coordinates and 3D surfaces whereas 2D does not. Therefore to move data
between the two sections of XCad there is a command ADD XCad in XCad 3D
which will import the 2D drawing into XCad 3D.
Documentation
-------------
Both XCad 2000 and XCad 3000 come with extensive user manuals and tutorials.
This short README file is intended to provide sufficient information to get
you started with XCad, however to fully explore the possibilities of these
powerful programs the manual is an indispensable aid.
This CD ROM demo version
------------------------
The demo versions of XCad on the CD-ROM are the full working version of both
XCad 2000 and XCad 3000. It will not be possible however to save your design
or to plot with these versions. These versions are for product evaluation
and testing purposes only.
Pricing and Availability
------------------------
XCad 2000 and XCad 3000 are available via many Amiga dealers throughout
Europe and in many other parts of the world. They may also be purchased
directly from Digital Multimedia at the above address at the following
special reduced prices :-

A small additional charge will be made to cover postage and packing.
The Future of XCad
------------------
Since its first introduction in 1985, XCad has been available as one of the
premier CAD products for the Amiga, and it will continue to be supported and
enhanced for this platform whilst there is still a demand for a professional
level CAD system at a price users can afford. However, in the last year,
the XCad technology has been redeveloped for X-Windows and the professional
CAD market. This has been not been a mere port, but an extensive
re-development of XCad, drawing on the experiences gained from the Amiga,
and the new product is now available not only on the Amiga under Unix, but
also on SUN, Hewlett Packard, Dec Alpha, Silicon Graphics and the IBM RS6000
platforms. This new version of XCad will also run on the 386/486 pc platform
under products such as DESQview/X from Quarterdeck Office Systems which offer
the X-Window environment on a pc. Call Digital Multimedia for details.
