vectorize a rhino logo and then cut it into plasma

[darksun]

Hello,
I wanted to ask you which program (better if free) I can use to vectorize a logo and then open it with rhino... I need to take it on the plasma cam and make a 3 mm thick cut of the above....I tried to open it as a background and then "calculate it" on rhino but it doesn't come out very well, I need lines(the contour) for plasma cutting...you know what I recommend to do? ? ?
thanks for the answers:finger:

convert your logo to dxf, and then from the plasma machine.

What kind of logo is it?
a vectorizer do not know, but recalculating it with autocad should be fast enough. . .

 

[darksun]

Plasma only serves the lines of the edge of the logo....only lines and arches, so I have to besides convert it to .dxf remove the colors and leave the edges, yes that there are programs that vectorize the images leaving only the lines... I'd like some advice on these programs. with rhino I put the jpg (the image) as background and then I recalc with the drawing tools but it comes out very approximate and I put a life to cure all the rays and curves:frown:

for example this atalanta logo I did it as I described it and modified it to be cut with plasma but I took too long and it is not beautifulView attachment logo.dwg

do not comment with the object of the logo that are in depression. . thanks:frown:

feel, if you open in autocad, you put on a layer different from that of the design, take the command line and the osnap "nearest", in just over a minute of recalculating all the design with more or less long lines a few millimeters.

do this, delete the original, purge the design and carry a dxf.

for plasma cutting is more than good. I did it for an esab pantograph with excellent results.

 

[Ezio Olivato]

look good like that, it is already in dxf!!! perfect for plasma machines!

 

[darksun]

Yes, but the lines are imprecise and I did everything by hand... too long!! !
does not exist a program that finds the edges automatically? ? ?

 

[Alberto.E]

Yes, there are programs that vectorize images, there are also autocad plugins that serve precisely this but sincerely I do not remember the name. Besides, I have done such a job for architectural tables from an eliography and I can assure you that the result is not of the best, you always have to waste time fixing and cleaning the design.
otherwise also illustrator has the function of vectorization and if the image quality is good by good results, and there is the possibility to export to dwg.

darksun: try to see if you are so rectified.
there was a defect in the curve of the lips...; I used the "contour" command and maybe in this way the machine digests it better.
Good job!
while for programs there is the suite of corel that allows you to vectorize directly from the pictures, but also others....

thanks ezio, in fact when I imported into the nesting cad for plasma(columbus) it made me mistake on the lips.... He said they were open curves while on rhino told me they were closed....mah I had to redesign the polylinea.... how did you see the error of the lips? ? ?
Thank you.

 

[Ezio Olivato]

Please! !
I wrote it, but I didn't tell you I did it with autocad: "draw"/contour; if there are unclosed areas, it does not generate the complete contour.
but did you look at the file that I attached to you in the previous post? Was it okay?

 

[darksun]

It's fine that with rhino, he gave me a closed contour... mah
However I resigned to recalculate all logos/figures by hand with the drawing tools of rhino... I think I will become an artist!!! thanks to all for the answers:finger:

sin you use rhino, has some precision sin compared to autocad that in 2d, as in this case, is definitely unbeatable in fact of precision.

 

[darksun]

probably autocad is more precise but rhino is faster and the 3d is simpler...then I have now taken my hand and travel well (within my limits in general low :biggrin ... besides autocad lt costs a bang... too much for carpentry where I work now

 

[Ezio Olivato]

Anyway, if you need to check before you go to production, don't worry, okay? ! ! !
good work and soon, hello

 

[darksun]

ok grazi ancora:wink:

Please, you're welcome!
