BeckerCAD ST

by Terry Frits (RACC)

CAD -- Computer Aided Design.  If you ask, I think most people
would describe a CAD program as a high level drawing package.  I would
describe it more as a drafting package, whose aim is accuracy in
drawing.  When I purchased my first Atari ST in 1985, I had
visions of doing all sorts of graphics on this fantastic machine.
Since then, I have not been disappointed, as many paint, drawing
and CAD packages have been released for the Atari ST and new
programs are coming out all the time.

The question to be asked
now is, "can the ST be a serious CAD machine?"  Well, several
years ago I would have said, "No, not with only 1 meg of memory,
the small monochrome screen, and slow graphics redraw, plus
limited printer/plotter support."  But, today that is quite a
different story, with the Megas, blitter chips, high resolution 19"
monitors, and a full array of printer/plotter drivers available.
The Atari line is becoming a true contender in the CAD market.

What really makes a CAD system, though, is the level of the
software available, and BeckerCAD ST is one of those programs to
be looked at by the serious draftsman (or woman).

First, let me say that my main purpose for owning a CAD system
is to draw house plans and do minor landscaping, not engineering
prints.  I do deal with engineering prints where I work, but I
don't work off our CAD/CAM station or draw prints.

Before I
list the features of BeckerCAD ST, I would like to say I am very
impressed with it.  It has one of the most user friendly
interfaces I have come across, using icons, drop down menus, plus
keyboard and function keys together, without using too much of
anything.

Superb Documentation

The manual is a hard cover, three ring binder with hard box -- the
kind that comes with a lot of the nicer Atari software.  The
manual has a table of contents, appendices, glossary of terms and
an index.  Each section of the manual has a cardboard
separator with tabs sticking out that make finding topics a
breeze.  Other software companies take note, PLEASE.

The sections
of the manual are...(1) installing and starting the program, (2)
introduction to CAD, (3) introduction to GEM, which explains
GEM and BeckerCAD to the novice ST user and introduces the
different functions of the program (including a tutorial), right
through to the professional features.  Next, (4) is the system
reference manual which goes into more detail on each function, (5)
is the appendix and (6) is the index.

The manual starts by telling about CAD and the different
uses in design and manufacturing applications.  If you are new to
CAD, I highly recommend reading this section.

As I read through the
manual, I would say to myself it's too bad BeckerCAD
does not have this or that special feature, only to read further
and find the feature of which I was thinking.  One of those features is
"break line."  Once I draw the outside of a house I want to break
a line to insert the windows or doors.  BeckerCAD not only breaks
lines, but also breaks circles and arcs.  Another feature was the
saving of the drawings.  I was thinking how I wished the program
saved the drawings so I could use them in my desktop publishing package,
only to find they can be saved in Degas .PI? or the .CAD
extender.

Harware Requirements
So, let's take a walk through BeckerCAD and see what special
features it has.  First off, the hardware requirements are an Atari
ST with 1 megabyte, TOS in ROM and one 720K floppy drive and/or a
hard drive (recommended).  BeckerCAD is a 2D drawing program.
Once the program has been installed, it is not copy protected and
may be copied to either another disk or hard drive (for
security/backup reasons of course).

As far as printers, the
program uses Epson/compatible dot matrix, Atari SLM804 laser, NEC
P5/6/7, Apple Laser Writer, HP Plotters and PostScript printers
and phototypesetting machines.  That should cover just about
everyone, I think.  BeckerCAD uses GDOS to print to non-PostScript
printers, but uses special vector character sets instead of GEM
fonts.

Feature-packed Icons

The program has two
sets of icons at the bottom of the screen -- the first set contain the
regular features and the second set are what they call the
"professional" features.  To change from one set to the other, you
click on the 1 or 2 box at the bottom left of the page.

On the far
right bottom of the screen are 8 boxes that have the icons used with both
boxes (named the right icon bar), and they stay
on all the time.  These icons contain the boxes to get the text,
trash can, arrow icon (which allows the manipulating of lines,
circular objects or cross hatching lines), range marking frame
(which is used to mark any desired section of the drawing for
manipulating), grid, 1:1 representation, zoom and last zoom
functions.

BeckerCAD ST also has one of the most unique UNDO functions
I have seen on any program.  In the bottom left hand corner of the
icon tools are four boxes with arrows in them.  The top two boxes
have double arrows and the bottom two have single arrows.  Two of
the boxes face left and two to the right.  When you want to remove
something from your drawing, you click on the single left arrow to
delete the last object you drew...click on it again and the next
object you drew is wiped off the screen.  Click on the right
single arrow and the objects are replaced in the order they were
removed.  The double arrows do the same function but keep removing
and adding as long as the arrows are held down.

If that isn't
enough, you can define a range with a rubber band and cut it to a
function key.  The range is saved to that function key, then the
range area is deleted by dragging it to the trash can.  When the
area is needed again, just press the paste option and the same
function key it was saved to, and back it comes with a crosshair
to place it where you want on the page.  This is a great feature
for moving furniture around in a room or making major changes.

BeckerCAD also has many circle drawing features.
There's the circle, ellipse, circular arc, elliptical arc,
concentric circles and ellipses, and circle and ellipse segment (pie
shapes).  Other geometric shapes that can be selected are
square, rectangle, triangle, parallelogram and polygon.   All of
these features (plus others) are in the first icon bar.

The second icon bar is described as "a series of very powerful
graphic and architectural drawing commands."  Mostly, these
commands allow for editing of existing lines and objects.
Some examples would be: plumb line, (which draws a line 90 degrees
to an existing line), trim first line, trim both lines, and one of
my favorites -- break line, circle or arc.  Others are: rounding
corners (makes a rounded corner from two connecting lines),
chamfer, pull lines and corners, change line length, create angle,
three point circle and arc, concentric circles, tangent between
point and circle and between two circles, plus many more.  There
is even a crosshatch feature, with the crosshatches being editable.

GEM Menus and Keyboard Shortcuts

The above are only the icons -- BeckerCAD ST also has GEM
drop down menus and keyboard shortcuts.  The GEM menu bar contains the
File, Layers (BeckerCAD ST has 300 layers that can be turned on
and off individually for viewing separately or combining to view
as a whole), Range (allows for saving, clipping, cutting,
pasting, etc. of objects) and Measure menus (to enter the sizes of
objects either manually or automatically), and a "Parameters" sub-menu
to set scale, precision from 1 to 1.000, and units of
measurement. There is also a regular Parameters main menu that
allows for screen setup, such as page size, turning on and off the
ruler, cross hair, grid and rounding.  You can also set the line
sizes and styles, cross hatching and text attributes from the
Parameters menu.

If all these things were not enough (and I have not covered
all of BeckerCAD ST's functions), there is more.  There is also a
macro interpreter called PS, which is a stack oriented programming
language.  This allows for exact placement in the drawing program.
It is very similar to the PostScript language and has full
function key shortcuts, graphics commands and math functions.

Symbols and Fonts

Now comes one of my favorite parts -- parts, better known as
symbols libraries.  BeckerCAD ST comes with a whole mess of them.
There are symbols for the electrical and electronic world, from
resistors, capacitors and diodes to home appliances,
lighting, meters and loud speakers.  There are also symbols for
the plumbing world (for real flow charts -- water that is!) and
the heating world, plus one of the best architectural symbols
libraries I have seen.  There are symbols for stoves, bathtubs,
sofas and counter tops -- there's even a grand piano.  The objects
can be loaded in, sized to your furniture sizes and moved
around to see how they fit in the room.  It sure beats picking up
the couch five times and moving it around the living room!  You
can also create your own symbols and save them to the library.
There is no engineering symbols library, but since this is not
a 3D CAD package, I doubt it would be used for extensive
engineering drawings.

One more feature and I am done with an
overview of this program.  I will quote from the manual, "The font
editor of BeckerCAD provides a complete tool for creating, editing
and processing fonts.  Even the untrained user can easily create a
personalized character set using the font editor."  Yes, BeckerCAD
even has a font editor that lets users design their own fonts.

So, What's Missing?

Now, before I start sounding like a salesman for Abacus,
there are several things I think are needed in this program.  I
would like to have the following: draw a point to end and middle of a line,
line to end of line and center of line, double lines and boxes (to draw
walls,etc.) and an integrated program for printing.  Output
programs are confusing and time consuming at best.  As long as I
am constructing a wish list, I would also like color dot matrix
printer support with each layer assigned a different color if desired.

The cursor seems to jump around a little when moving on the
screen, and it seemed a little sluggish.  I was running it on my
1040ST, and when I switched to the Mega 4 with blitter chip turned on
it worked much better.  I don't see this as a serious problem
but an annoyance more than anything else.  When drawing lines,
(like tangent to two circles), the line does not appear to touch the
circle sometimes, but when I zoom in on the area the lines are
touching.  This may be a result of the monitor not being of a high
enough resolution, but it can be confusing at times.

Most of the
above wants can be done with several keystrokes or operations, and
should not stop anyone from buying this program.  I understand
Abacus has been offering several deals on BeckerCAD, making
it a real bargain in today's CAD market.  BeckerCAD is easy to use
and learn and appeals to the artist/architect in all of us.  Give
it a try, I don't think you'll be disappointed.
