TurboCAD Learning Edition, is a comprehensive, fully functional
2D CAD software product. It is the ideal vehicle for new users to learn
how to use and discover the concepts behind CAD software. In addition
it is a viable product for producing professional 2D CAD drawings. The
software includes the very informative "Complete Guide to Learning CAD"
by Randall Newton and Robert Berry (271 pages), the useful crossover
guide "TurboCAD for Users" (144 pages) and a full multimedia Quick
Tour. This will reduce the learning curve and provide easier
accessibility to the software for the entry-level user.Complements existing CAD
seats within a design environment.Powerful enough to be used by dedicated CAD
specialists.Easy enough to use by non-dedicated, occasional users.Customizable
User Interface.Compatible with MS Office and other productivity applications.OLE:
Drag and Drop drawings into any OLE compliant application.Easy to Learn
and UseSetup wizards using real world input.Templates for every discipline and
measurement system.Extensive multimedia tutorial.Handle based editing with the
precision of CAD.Context sensitive Edit Bar with constraints.Context sensitive
local menus. IMSI
is making its Learning Edition available for free with the firm belief
that users will learn to love the TurboCAD product and will want to
upgrade to our latest 2D/3D versions. Research has shown that CAD users
typically remain with the CAD software they learn first, favoring
techniques and procedures that they are already familiar with.

| Subject: | TurboCAD format files |
... A major bug (in my opinion) that TurboCAD folks claim will be fixed in v15.
Of course, to get that you have to buy it AGAIN. Nice customer experience, huh?
I experienced numerous program crashes, hangs and
data corruption when editing and saving AutoCAD format files using
TurboCAD v14. After numerous emails to TurboCAD customer support, they finally
mentioned that editing files using native TurboCAD format is better supported
(doh!). No problems since then and life is now
good!
AutoCAD format=READ ONLY

Hi Jay,
The TurboCAD I've used, versions 11 thru 14, never gave me any
difficulty saving files as AutoCAD and bringing in AutoCAD files to
TurboCAD.
This was necessary because engineering staff were using AutoCAD to model
many of the systems in 3D which was much faster
in TurboCAD as well as rendering in color. Never had any problems so
long as you saved from the version of AutoCAD represented.
I've never had hangs, crashes or corrupted data with TurboCAD in 6 years
use. It replaced ProE and AutoCAD for design work where intensive
data wasn't needed for repeat manufacturing. I think it's great
software despite IMSI having an odd marketing group.

This is all true, but we also need to not confuse the lab with the real
world. If you are in a dark room with two point sources of light that are
of a whole order of magnitude of brightness different, and they are
illuminated individually and alternately, you would likely have a hard time
telling which was which. This is due to the adaptability of your eye. If
you had a constantly lit background and did the same test, one source could
well be distinguishable while the other was lost in the background.
Now consider flying near dusk and it's right about 3 miles vis in haze. A
more powerful strobe will be visible while the weaker may not, although
there may be zero practical difference at midnight in a cold, clear, winter
sky.
I used the most powerful strobes I could.
