but how many post back had you been advised?testone?!!! At the end of the day he tried less!
so you understand why those who insist: succeed!
joke of course::::...... ! ! ! ! !

Okay, I give up.......:36_1_3:

But just to understand, why is this?? Perhaps in version 12 do not exist spline? and therefore are converted into poly3d? ?

However this method does not allow you to manage the accuracy of the object.:smile:

Hi.
 
and no, but the accuracy you have to set it up and check before making the conversion!
for the first question, I have no answer ready, although I think things have changed in the passage from r12 to r14. I hope someone with more knowledge of the cause has a more explicit explanation.

There were splines in version 12. were introduced with the r9.
Unfortunately more accurately than that method of conversion I do not see solutions at the moment.
If anyone comes to mind well come... .
 
I have reported this link:http://cadpanacea.com/node/70where there is a lot of information about it, good reading!
of those, the method of wmfout/wmfin had not really come to mind.
the problem is that the method that achieves greater precision is that of the saving in dxf r12, creating a 3d polyline.
Unfortunately as blubossa says:
...however this method does not allow you to manage the degree of accuracy of the object.:smile:. . .
That's why I don't see a more accurate one. :frown:
 
flatten transforms into a poly 2d with archi.
Where can I find this lisp? ?

the rescue in dxf12, and the spl2pl routine does not create lines and arches, but only lines and send to a cnc machine of the composite curves of thousands of lines creates a myriad of problems.

Hi.
 
mumble, mumble... but you only have autocad available? because there would also be another method, using corel for example!
but beyond further conversions, try to post this spline that we look at him, maybe in 2004 format! or a similar one, here is right to see what you can do and how!
also why to cnc what type of file format sends? Not dxfs?

Here is an example of what I want to cut to the pantograph.
the file that steps is just a dxf that is then imported into a cad-cam system and then the cutting work is assigned and exported to the format required by the cnc machine.

this is the result by converting it to poly3d. Obviously the file gets heavier, and as for the cnc, I don't think it has any problems managing it.
the procedure I used was the simple conversion to dxf r12, saving and closing the current file. reopening the newly saved dxf file!
good job blubber

Hi, Ezio.
I used the same procedure, but if you explode the polyline, you realize that it is formed by thousands of small lines, what I was looking for is that it kept lines and arches.

try to imagine a cutting machine that to cut a letter must perform thousands of segments...............no good!!

hello and thanks for the comparison.

Meanwhile I place my best wishes for good holidays at all the participants in the forum.

Thank you for your best wishes.
returning to your trouble dear blubossa the question does not arise, and now I explain why!
therefore the cad-cam program of the machine operates the conversion of the dxf file to the optimal operating format for the type of processing that is asked to the machine to perform. experience gained in laser cutting, where the track is decomposed in two-way linear path, like old needle printers to understand, and if the source file is not in dxf, the machine refuses to process it. Now I don't know what the cutting method you want or you can make the writings, but if you tell me it's a cnc or it works with engraving tip, cutter; or laser. which means in any case that there must be no moments of discontinuity in polylinea, otherwise at every change of mathematics, from arc to line and vice versa, a detachment is generated during processing.
I hope I have not exasperated you with the dxf tests, but also the laser plotters want the dxf files, at least those I have seen working to perform the writings on self-adhesive films for cars, windows and the like.
 
....but if you tell me that it is a cnc or works with engraving, milling tip; or laser. which means in any case that there must be no moments of discontinuity in polylinea, otherwise at every change of mathematics, from arc to line and vice versa, a detachment is generated during processing. ...
so if it is so the most accurate method remains that of the dxf in r12...
 
I exhume the discussion because we are, it seems to me to understand, you stay at my problem......
So I arrive at a beautiful polylinea, both 2d and 3d saving it with r12............I can also increase or decrease the knots of polylinea with chorel draw.........but our cnc from carpenter (uniteam) reads only dxf formed by strings and lines..........is there anything to transfuse a polyline (or spline) into strings and lines without me getting rid of disaster ?

Thank you.
