Jeff,

This may or may not help you. It is looking at the adapter plate
from the
prop point of view with a dual set of dimensions. The radial set
came From
Tracy.

BTW guys I suggest everybody get a copy of free Q-Cad as it works on
both
Windows and Linux. That way I can send you 3 view 2D dxf dwgs and
you can
dimension them yourselves if you are interested or need to make the
part by
hand.

Other wise I need to do a lot of extra work as modern 3D cad dwgs
don't
normally have dimensions on them. They are drawn to exact scale and
they
can
be loaded into a NC Mill without anybody reading the dimensions.

Paul Lamar


Q-cad installed and running, but it's not really free. It terminates
at 10
minute intervals, then after 100 hrs total for good. However $35
isn't bad
for the ability to get some stuff done and not have to take up time
that
could be better spent upgrading Kasauga mills, or designing new
stuff for
rotary aviation.

Thanks Craig. I think it is well worth the $35 for a 2D cad program.
Seems rock solid. I'll send some dxf's for it shortly.
In fact try this one and see if you can dimension it.

Paul, I bought a cad program on e-bay for $24 called  DesignCAD
3Dmax v18
just to try out the rendering part. It does 2D drafting and 3D solid
modeling, 3D rendering and animation and has a huge symbol library.
I seems
easy to use with all the normal drawing commands etc.  They had
about fifty
listings on this program recently.It has multiple import/export
formats
including dwg and dfx as well as a lot of newer ones.You own it
outright, no
time or save etc limitations.

Does it work on that 2D dxf I just sent.

Paul -

I went to get the Q-CAD program you mentioned, even at the 39 EURO
price (about $60 US).  Especially since it works on Linux.  (I prefer
Linux and Mac, and use Windows when there are no alternatives -
unfortunately many electronic and programming environments only work
in Windows.)

I was intercepted and advised to get TurboCAD instead.  We can get a
copy for the Apple Mac pretty cheap on eBay.  The current release for
TurboCAD Mac is v4, and it comes in the following levels (for Macs):
- 2D Designer (entry level)
- 2D/3D Deluxe (mid level)
- 2D/3D Pro (professional level w/extras)
The Windows versions have different breakdowns, but you get the idea.

On eBay we can get an older balls-out version for $24 all day long
(TurboCAD 2D/3D Pro v3).

I saw the older mid-level version go for $5.23 today (TurboCAD 2D/3D
Deluxe v3).

(Both prices include shipping.)  Note that the previous Windows
versions are even cheaper than the Mac versions.  Not bad for those of
us who dabble in CAD, right?

Whaddayathink?  Is TurboCAD okay for our use?  I ask because even I
can afford $5 - $25 to jump start CAD learning & use.

-Vince Orton

I went into the Linux  Package Manager and found Q Cad.

Application> Engneering Scientific>Q-cad

Q-cad for Linux is free and installs itself with one click.

I know nothing about turbo cad.
