'[EE]: Protel'

Bob,

AFAIK, Protel is the only ECAD packkage that will export it's board outline
directly in 3D to Pro-Engineer, a task that takes me an entire day by hand.
That alone would make me interested in using it.

Currently I export a board to DXF in Eagle, convert it to DWG in AutoCad,
draw it in 3D, export it in an STL stereolith file, import it into
Pro-Engineer, and then draw it AGAIN in 3d in Pro-E, and hand it over to the
mechanical guys, who say "IT WON"T FIT!" and then I have to do the whole
process over again.

I'd pay real money to somebody that could convince EAGLE via a hack, ULP, or
external software  to export a 3D model directly into something that I could
use in PRO-E.  The task is beyond me.

So what is wrong with Protel, besides being way expensive?

eek! Pro-E! More evil!

Oh yes, Pro-E is among the most evil things ever to be concocted by human
nor devil.

Just this morning, as my mechanical compatriot got the "Blue Screen of
Death" once again, after not saving his files for an hour once again, he
remarked to me that Pro-E would not load my 3D board layout, because it
could not create some internal datum plane or other.

Pro-E has the most convuluted system of cascading menus ever developed, when
a simple two-key command can suffice in AutoCad, Pro-E requires two dozen
mouse clicks for the smallest task.  A 3D box that can be created in AutoCad
in six clicks probably will not regenerate in Pro-E, requireing you to "Fix
Model".  Once you start on a process in Pro-E, there is generally no
stopping, you have to finish, then delete the part you just made.  No Undo
key, often no cancel key.  Menus for the same thing often have two different
interfaces, which will pop up one after another.  Sometimes things
dissappear for no apparent reason.  Cursors change, never change back.
Imagine trying to draw something with a "NOT" symbol as a cursor, a circle
with a slash through it, where the hot spot of the cursor is behind the
symbol.  I do that every day.  Pro-E runs fine one minute, the next minute
it's got the slows, every menu takes a minute to load onto the screen.
Usually a session like this results in the blue screen of death after an
hour.  My boss can bring up Pro-e, wiggle the mouse pointing at a part, and
get the blue screen of death.

Pro-E will not import any 3D file that can be read or written by an AutoDesk
product, by design, except IGES which Autodesk charges extra for, and STL.
In ProE, STL files come in like ghosts, you can see them, but they don't
have any surfaces or features you can use.  Thus, I have to draw the board
AGAIN in Pro-E, after drawing it once already in AutoCad.


I guess all this software experience looks good on a resume.

Actually the 3D feature of Protel is only a toy. You cannot set the height
of components, instead it just uses some unchangeable fixed sizes based on
the Protel standard part designators :-(.

When they announced the 3D viewer I was tempted to have our company upgrade
from Protel98 to get that feature. Thankfully I got the real info on the 3D
viewer from the independent Protel Mail list before I had us waste our money
(none of us here can find any new features of P99 that would be useful to
us). Basically the 3D viewer is only suitable for impressing
Marketing/Sales/Management types :-).

There is a third party add-on for about $1000.00, I think, that lets you
generate 3D models were you have complete control over the 3d parts
outlines.

FWIW - Protel has bought a bunch of other companies, including P-CAD, and
now goes by the name Altium.

When they asked me, I recommended SolidWorks, but my first choice was
Autocad Inventor.  They chucked 50 G's into a Pro-E Rathole, however.  Now,
since so much money has been spent, no one is allowed to say anything bad
about Pro-E.  That's my honest opinion.
