I made drawings using Solid Edge. Months later when I tried to open the drawings,
Solid Edge said that my license had expired. It would not let me look at
my drawings unless I renewed my license (free). This happened again the following
year.
I got to thinking, what will happen if Solid Edge changes their licensing policy
or if they go out of business? I will not be able to access my drawings.
So I switched to TurboCad, although it is not very intuitive. I prefer programs
that are easy to learn without having to read the help files.

i have an odessey 625 that is 5 yrs old and has only begun to be used last
oct. it has spent 100% of its life on a schumacher maintainer. now i at
times run into a situation where the battery won't spin the engine. other
factors may be involved too. this is a jab 3300 with the old model starter,
engine is new, engine is tight when hot.
soooooooo i don't know if it is my starter or battery is to blame.
i took the fully charged battery to carquest and a load test said it was
good. i know how load tests were done 20 yrs. ago, can they be done so
easily with a 1 lb. handheld digital thing as carquest used in a few
seconds?
here are a few stats on my battery on the tender and where its voltage
goes after being taken off the tender.master solenoid, starter solenoid ,
diode were installed per b and c instructions. any opinions where to go
next?
battrey charge immediately after coming off tender...13.23 volts
after 24 hrs
off.......12.92 volts
after 5 days
off........12.74 volts
is it possible my wiring setup is causing a draw? i have not disconnected
it and checked voltage yet.
any suggestions appreciated.

Then microCAD (or any of the AutoCADS) are
two excellent solutions. They understand English.
If you want to draw a line say "line<cr>" and
then enter a from (intersection, nearest, tangent
midpoint, etc) then a to (same constellation of
options) while guiding to those terminations with
the mouse.
Further, AutoCAD and nanoCAD have .pgp 'overlay' files
that you can edit with an ordinary text editor like
notepad.
A, *ARC
AA, *AREA
AL, *ALIGN
AR, *ARRAY
BL, *BLOCK
BR, *BREAK
CI, *CIRCLE
C, *CHANGE
CH, *CHAMFER
CO, *COPY
D, *DIMSTYLE
DDI, *DIMDIAMETER
DED, *DIMEDIT
DI, *DIST
DT, *DTEXT
E, *ERASE
ED, *DDEDIT
EL, *ELLIPSE
EXIT, *QUIT
F, *FILLET
H, *HATCH
I, *INSERT
L, *LINE
LA, *LAYER
LE, *QLEADER
LI, *LIST
LT, *LINETYPE
LTS, *LTSCALE
M, *MOVE
MI, *MIRROR
O, *OSNAP
P, *PAN
PE, *PEDIT
PL, *PLINE
PG, *POLYGON
PU, *PURGE
R, *REDRAW
RE, *REGEN
RA, *RECTANGLE
RO, *ROTATE
S, *STRETCH
SO, *SOLID
T, *TRIM
V, *VIEW
WB, *WBLOCK
XP, *EXPLODE
XT, *EXTEND
Z, *ZOOM
When you enter the short command, the cad program
interprets it for the full command. I found
that I could draw left-handed with the mouse
while one-hand typing with the right and
go through the 'dance moves' with greater
rapidity than by accessing all those little
tool-bar boxes (most of which I didn't need/
use). In fact, I can turn all the tool-bars off
and have the full, un-clutered screen to work
on.
Aside from the isometric drawings I made for
illustrating the 'Connection, I've not found a
strong need for 3d drawings. If you need that
capability, I'm not a good source for advise.
Your personal .pgp file becomes a good teaching
tool too. Out of hundreds of commands that the
CAD program understands, editing your overlay file
down to those you use 99% of the time make the .pgp
file a sort of syllabus for a short course in
AutoCAD. Search the 1-inch thick book of 1000
commands for how these few work . . . you'll have
99% of your dance moves learned in a very
short time.
In fact, I would recommend that anyone wanting to
get their feet wet in either AutoCAD or microCAD
cut-n-paste the list above into a new version of
a .pgp file and print a paper copy too. Hang it
on the wall behind your monitor as a reference
list. This will steepen your learning curve
greatly. You can always add/delete commands to
customize the list to your own needs but I'm
betting that becoming proficient in those
listed will get you up to speed very quickly.
Turning off all the tool bars and talking to
the program in 'English' is about as intuitive
as you can get. Over the years I've spent thousands
of dollars of my boss's money on AutoCAD and sundry
upgrades. nanoCAD now does everything that cost
us the price of a good used car . . . for free.
Interestingly enough, NONE of those upgrades added
features that I needed for my work. Everything
I do today can be done in say AutoCAD R10 for
DOS!
There may be other applications that are as
intuitive and/or attractively priced . . . don't
know. But I can tell you that nanoCAD is an
exceedingly good value and easy to learn if you
start with the few dozen commands I listed
above.

I just wanted to stop and thank everyone for their suggestions and
help as I was searching for this gremlin. The fix did turn out to be
installing that $11 in-line audio filter into the audio jack on the
396 and sending it on its way to the intercom. Jumped in, fired it up
and taxied around for the first time in peace and quiet.
The 'filter' is probably a simple isolation
transformer as opposed to any sort of noise
rejection device. This technique is used to
break any potential (orrealized) ground loop.
Back in the good ol' days, audio inputs and many
outputs from the 'higher end' devices had such
transformers built in. These were common to audio
amplifiers for large installations that might have
signal or microphone cables hundreds of feet long.
I used to shag audio systems for a group of acoustic
music aficionados and learned about the usefulness
of such devices first hand. When your mixer board was
100+ feet of wire away from the power amplifiers, the
potential for ground loop noises was very high.
Yeah, even carried the stuff around in a VW microbus,
just no psychodelic paint job!
There have been cases where I would have liked to
install such a transformer in TC aircraft . . . but
that's a "no-no" without a lot of paperwork; change
of configuration. Hence, it's not uncommon to hear
buzzes, whines, pops, etc. in the audio systems for
REALLY expensive machines.
It would have been interesting to locate root
cause for the original loop, but not worth tearing
into hard-to-get-at wire bundles, etc. None-the-less,
a loop-breaker transformer is an elegant fix.
