I got some Cyberware 3d-scanned objects but they are impossible to load
into Autocad because its huge solution. Too much points (~200 000) per
object. It needs about 30 minutes just to load such a drawing, not speak
of any operation.
You need an external program to smooth the mesh before you can think of
importing it into any CAD program (3ds had the 64000 vtx limit then).
With 3DS there's such a tool called OPTIMIZE or REDUCE (I forgot) which
reduces the vertex number. I brought my head down to 3000 vtx's andf
this was okay.
For the first conversion (to get it into 3ds) I wrote such a dos exe for
the cyberware format. I'll send it on request.
BTW: Cyberware is the manufacturer of such 3D Scanners. (Monterey, CA)
Incredibly good stuff and very nice guys there.
But there're also 3D "printers" out now!

Mort, the size of the dimension lines and arrows is set to the scale:
for 1/2 scale, feature size is 2x etc.
My sizes always come out right this way.

I got to say, if you dimension in pspace, then move pan or zoom, all the
dimensions are "moved". IMHO, this is not a problem in mspace
dimensionsing.
MAYBE you should try to understand my method, it is very easy.
Your clients ought to know there is more than one way to accomplish the
same thing, give them the choice.

Please, this is really an unwarranted comment..my method is for a 3
viewport drawing of a 3d model.
For 2d drawings w sections etc. only one layer is needed.
If you really want to know how to do this stuff, let me know.
But please, don't knock it until you have tried it!

Hey Mort, take it easy, geez, .. it's a suggestion, not a command!
Hope somebody out there can use this idea.
Please advise if you want a proto drawing.

Jim, before this goes up in the roof, I have no problems understanding
your method or any objections to why you do it. The reason: There's NO
general function in Autocad to do a proper dimensioning in paperspace.
That's also the reason why _all_ my clients were dimensioning in MS in
the old days (when PS/MS came). But this was not to their satisfaction.
Some asked me to figure out how to put the dim's 'were they belong' (as
they said). So I did. That's all. And after figuring this out, I never
claim MS to be the correct space. But, believe me, previously I
dimensioned in MS, but I never was comfortable with it. I didn't feel it
was right to mix the geometry with texting of the drawing.
> If you really want to know how to do this stuff, let me know.

You describe very well how you do it, and I have tried it. If you insist
on putting your dim's in MS it's a good way, because you have your
pre-defined set of layers, already frozen upon initialization. And as
you say it, your method works well when you have a pre-defined drawing
lay-out. This is not always the case, and that's maybe the reason why we
end up with different solutions to the same issue.

I could have been more clear on this one, but what I meant was that when
you have multiple sets of dim's on a detail, you don't want all dim's to
be shown on all viewports. Main dim's are not shown on a detail, as well
as detail dim's are not shown on a general view.
Hope this is better,

Hi
I think your problem is that your menu file has got locked somehow.
See if you have a *.mxk file.If yes,unlock it with the options-unlock
file command.
Hope this helps,

Hi
The number of lines is controlled by the facetres variable.
FACETRES -Of type real.Default-.5 Range .01 to 10.
But if you decrease the value , the smoothness of the cylinder will
be lost.
Hope this helps,

Great news - the 1.12 driver has just been released! I am currently
testing it. It claims to solve the problem.
Pity Matrox don't bother to inform us or even respond to e-mail. Why
even bother to have a tech support e-mail address? Matrox lost a few

Matt,
I have the same situation. I have always read that you are supposed to
dimension in model space (through the vport) but I didn't like doing
this. Of course, if you do, make sure you dim. on the proper layer
(vpname1-DIM, vpname2-DIM, etc.) These vports are independantly frozen
in all other views.
I like to dim. in paper space. But when doing a dia. etc, I have to
redraw the circle on top of the one showing by using the CEN snap and
tying in the known radius/diameter. FYI, I believe that if you were to
jump into the view, and do a UCS, OBJECT and select the circle, jump
back to paper space, you will find that the QUA and NEA will work. QUA
and NEA will only work when you are on the positive side of a circle or
else its undefined. Hope this helps

Hi All,
I'm not sure where or if this fits in here but; In reguard to XREF's;
Example drawing; A detail drawing with the "Border" as a XREF.
If the "example drawing" is inserted in a drawing, the *border xref* will only be
displayed if the *border xref* is already attached th the drawing, if not, only the error
text will be displayed.
Maybe this program can make it a bit more clear;
In C:P2270dwg, the drawing is first attached, then inserted. This is a little trick I
learned while trying to update some assembly drawings and the associated parts.

My point was simply that the SETENV function apparently requires that
both the variable name and its value be quoted, and that it is a valid
function in R12c4. It may not exist in R13, but the input shown in the
R13 example is not definitive; try it again with both parameters quoted
and see what happens.
I might note that my participation in this thread is strictly out of
idle curiosity, as I personally have found no need for a SETENV
function. I do, however, find undocumented features intriguing...
