Hello everyone,
I have a problem that's been haunting me for weeks, and I can't handle it.
use rhinoceros, but the person for whom work wants a dxf for laser cutting.
I tried everything, to bring the model in sw, but nothing.. does not work.
How can I do that? Does anyone know if there's a chance to get a dxf file like in sw?
Thank you in advance.
 
Good morning.
but I actually thought about this operation. But I remember doing evidence, sent to the person who wanted the dxf, and I was told that it was okay. :36_1_4:
the procedure you told me works 100% for laser cutting?
 
Did he tell you what was wrong?
dxf is a "neutro" format that read practically all cads, a bit like iges and steps for solids.
he who cad uses?
 
That's the dilemma. in the sense that I work for a designer (a parigi) who always had people working with solidworks, and that from they pulled out the dxf. I using rhino and beyond all having never done it, I don't know which side to do me again. In short, it is the designer who sends the file to people who deal with the cut here in France, so I have no idea what is wrong, whether the format itself or if there are problems in the drawing. However, in the week, I'm trying to find out more, even because this situation has to be solved for the future. :
 
you can also do a "Save with name" and select as dxf format.
attention, in dxf is a drawing format, it is worth for lines, curves, tips etc.
If you expose us to a surface or a solid, nothing comes out of it.
who laser cut needs a profile that is defined by curves and lines, perhaps it is here the hippo.
 
Yes, I had guessed reading a bit on the internet of this dxf.. mah, let's see if in the week I solve. Then I'll make it back alive. :
Thank you very much.
 
I got your problem, too.
who works laser cutting in 2d needs "only" of clean entities and profiles, you have to prepare them well, if you want them to use them.
then, create a layer inside your design that you will dedicate to the export of the dxf, where you will save the external, internal profiles, circles, lines and points you need to make the particular laser cut.
to do this, use the functions of "extreme face contour", "extreme edges", if you are starting from a solid, taking care not to leave lines, polylines or circles in vertical position, and not to leave any duplicated or partial body under other entities.
I better explain: if for example your piece is a sheet rectangle, under that rectangle there must be nothing, sometimes drawing can happen to forget about the line pieces in the main profile, this at some cam does not create problem, while at others yes.
as well as the circles for possible holes: if they are coincident it must be one only, not for example two overlaps with the same center and the same diameter (although perhaps on different height planes), because some cams with this go in tilt.
You also need to check that all entities that you want to export lie on a horizontal plane, who cuts with 2d laser use only two sizes, width and length, and many cams do not accept dxf files that come from non-flat entities.
when you have saved in the "2d" layer all the entities you want to export, just let it on, select everything and export to "dxf" format, saving with a name the file obtained, which at that point you can send.
in good substance, to export files to use in a cnc 2d it is necessary to understand that all that for you is a design, for those who import your dxf it is profiles, consisting of straight, circles, polylines, that can be closed or opened, that have a direction (clockwise or anti-clockwise) the direction of which however usually can reverse even those who then use the file in a cam, of the rest.
the main problem, therefore, when you want to extract a usable dxf, is to leave us in "only" the necessary strait.
dxf is the "basic" format for the interchange, and much of the success of the exchange also depends on the level of update of the programs that are found to use the exchanged files, sometimes cam programs a little "vecchiotti" mi digest files from recent and updated cad.
Let us know.
Bye!
 
Hello blizzard,
thanks to the explanation.
precisely with regard to horizontal bodies, consider that my object is a stylized ominous walking, it should be then in steel, with arms and legs bent.
Well, obviously, I have to do the way that the omino is "right", I mean, it must lie on a horizontal plane.
I found two commands I didn't know. But I don't know if they are right, if they keep me all the exact proportions and measures.
Do you know anything about it?
 
Hello vale 1981.

So the stylized man you're talking about is a three-dimensional one, right?

about the commands you found, what are they?

what you are trying to do is get some kind of projection on the plane of the figure?
 
the command is smash (rhino 5 English).
Do you know him? However, yes, the omino is three-dimensional. It has a thickness (which should be that of the sheet, then it has the arms and legs in motion position.

The smash isn't good, I think, better the squish even if the precision is always relative.
 
but nobody then uses rhino to get dxf files to use for cutting?
I wonder how that's possible. .and even in solidworks there is this option that is immediate. Unfortunately, I don't have time to put myself there and learn how to model with another program. :

in solidworks carry out the sketch you use for extrusion or feature, rhino has no sketches connected then.....
but should your piece already be on the floor, or after cutting the piece should be folded?
Can't post an image?
 
no then, I did the model as it should be, then make the render. so I have to flatten it in rhino, to get the dxf for laser cutting. not place photos because the object is not mine, but the person I work for.. :

Try squish, it should solve your problem.
 
I agree with technomodel.
the smash command, and that develops surfaces, create a sort of flattening of the original surface.
precision always depends (in rhino, of course) on the type of surface that is being treated.
with quite regular surfaces you have a good result, with complex surfaces....depending......
