extract cut image (with extruded cut) on cylinder

[Arduinoasd]

Good morning to all, I looked through the various discussions and around the net but I did not find what I look for.
I would like to make on a cylinder with a diameter of 114 mm and with a thickness of 3 mm a skull (for my personal taste and not for work) using a lser tubes.

the procedure I have followed so far is as follows:
searched for the image I liked (Raster format) and converted into vector image so that you can save it in .dxf to open it from autocad and continue to work on it.
in autocad I arranged it so as to create joints where I want the material to remain and where there are, in fact, the material once the laser cut passes will have to fall.
the problem is created when, I want to import the .dxf file on solidworks to apply it on the cylinder and create the extruded cuts so as to have the "finished" piece to then be able to import it into the cam language and make it work to the machine. I don't know how to import this file and make cuts, with the decal function sticks the image above and doesn't make me work.
perhaps mistaken way of approaching or there are other methods to do this kind of work.

thank you very much to those who will answer me

if you already have the dxf import that, enter dxf/dwg.
insured in the dxf of having the origin equal to that of the 3d to avoid annoying shifts

Good morning and thank you @massivonweizen for the answer.
the file on cad I fixed it on the origin but when I try to put the image above the cylinder nothing appears to me. even if I go on insert dxf\dwg (I tried both files) on a new solidwork document makes me insert it and I get an error "input file dxf\dwg invalid or unfulfilled. impossible to continue conversion). I don't know what I was wrong about the cad file, do I have to convert it as a polyline?
I apologize for all the questions but I know little about the programs and online I have not found answers to my question.

 

[MassiVonWeizen]

I can't open the dwg because saved in too recent format. I have 2013.

the file on cad I fixed it on the origin but when I try to put the image above the cylinder nothing appears to me.

dwg should not contain images; that entities are or not polylinee has no relevance.

 

[Arduinoasd]

I apologize, but I vulgarly call it image, I refer to the dxf\dwg file.
Now I saved it in the 2013 format, thank you.

 

[MassiVonWeizen]

In theory, it shouldn't have a problem. try putting everything on layer 0 since in the import the only difference is made on the type of line so as to insert those uncontinuous as construction lines. try saving it as dxf. the origin of the dwg must correspond with that of the part and I imagine that your tube has the origin on the axis and not moved to the left.
what is the version of solid (please enter it in the profile)?
you need to know the exact procedure you do when entering the dwg.
also attach the part and Monday I make a verification

 

[Arduinoasd]

put everything on layer 0 and made the center "" of the image" (pass me the term) coincide with the origin of the axes;
the version of sw is 2018 (updated also on description), I had the origin of the tube on the axis for this I renamed the .dwg file;
in the .rar attachment, there are both the .dxf file and the .dwg and two parts, the tube and a proof that I made on a hypothetical sheet even if I would like to succeed in doing it on the tube right.
the process to insert the file is: insert->dwg\dxf. As far as the tube is concerned, it still gives me a mistake while for the sheet, more or less have I managed to stick it over? (it opens a window and makes me import the file and I choose 2d, then I don't know cmq how to move on).

Thank you very much for the advice and patience.

 

[MassiVonWeizen]

if on the sheet it matters and on the tube not probably, I go to intuition, it is because you select the curved surface. on curved surfaces you can only create 3d sketches while that imported from dxf is always a 2d sketch.
create a tangent plane to the tube and use it to import the dxf.

opens a window and makes me import the file and choose 2d, then I don't know cmq how to move on)

What does that mean? go on what?

Maybe it would be the case that you did at least the basic tutorials, inside the program, to understand how you model in solidworks

 

[re_solidworks]

as it suggested mass, you have to make a tangent plane to the cylinder and paste there the sketch. the sketch can also be inserted with a simple copy/paste from autocad, as well as with the command insert dwg/dxf. Once inserted, use the winding command to attach it to the cylindrical surface.

 

[MassiVonWeizen]

doing a quick test I don't understand why he gave you the initial error as if you select a curved surface the program warns that it can't be used to insert a dxf/dwg.
However I see that the concept of origin is not clear to you; If your tube has the origin on one end you cannot do the dxf with the origin at the center of the image because it means that when you import it you will have half sketch on the tube and half out.

 

[MassiVonWeizen]

you will also have to do a huge cleaning work of the sketch because in order to be able to wrap it, and consequently cut, on the surface there must not be intersecting areas or confined areas like those of the image
helped by setting in tools> sketch settings the setting shaded sketch; when you have all the shady sketch it will be possible to wrap it

 

[Arduinoasd]

especially thanks for patience and answers @re_solidworks e @massivonweizen , I am a beginner with both software, I have never used them to work for this I make trouble on things that are banal to you. In fact, the design I would like to make is more for personal use and for stubbornness? cmq I will try again and I will try to follow your advice, bad that goes, I will make it pay by someone.
