spianare surface

[volaff]

Hey, everybody, guys, I have a problem.
I have a .stp file and should cut some sort of sheet to paste on it that goes to cover the surface of the piece.
it is possible with rhino (which I have never used before) to do this ie to smooth the affected surface and create a file (dxf maybe) to be able to cut and paste on the part that interests me?

I hope I've been clear enough.

thanks to anyone who wants to help me.

I mean, you have a solid, and you practically want to take a part of one face and replace it with something else?

someone who knows how to use rhino I strongly hope that it is able to do it...I unfortunately do not know how to use it, but with what I know to use it I can do it quietly; )

 

[volaff]

No.
from a solid I would like to get the sling of the solid itself on a plane (2d).

then it will be enough to do a Boolean subtraction, but one thing like that you do it in freecad...
amounts the solid in a new file, draw a huge cube, the positions where you need and subtract

honestly it doesn't seem so simple in the sense that an account is projecting on a plan an account is spying on.

should be the unwrap (literally "wrap" as you do with candy).
for example the unwrap of a cube is that of the image below.
Rhino definitely does. In practice the unwrap is a mapping operation that you do before applying the material to solids.
I don't know about rhino, but on 3ds max, once the unwrap is done, you can also save it as an image to be used in the creation of materials.

figures such as parallelepipeds are simple forms and the corresponding unwrap is easy. different discourse is the unwrap of complex forms, for which there are other mapping techniques, for example pelting (what I used in this video ... link (from minute 19:22)
What figure do you have to "write"?

in rhino 6 in surfaces> surface area there are commands that allow to develop even complex surfaces. as regards the solid there are no direct functions, but one can make a surface at a time

the surfaces are quite complex. back type and seat cushion for us.
Thank you very much to all.
I see if I can fix it!

Thank you!

on rhino is called aroll (the same thing as a 3ds max unwrap). it is also possible to do it on individual surfaces, of course.

 

[ale47p]

ah ok I understood badly, indeed terrible...now I understand what you mean!

It seems strange that rhino does not manage this very important phase called solid mapping, even complex. They call it improperly "betting" but it's actually the real unwrap.
Usually these software propose a cut of the "skin" of the solid and is to the modeler decide if those cuts can go well for the operation of "splanning" of the surface. There should be a whole set of commands that make this important operation possible. rhino makes rendering, so it definitely has these tools.

I made the "splanning" of the cushion surfaces and an entire armchair, using the pelting method. the operation is visible in this video from minute 19:22 onwards. videoSurely rhino can. you must first decide how to make the cuts to "spin" the solid. in the video you can see the technique.

thanks to all for the precious suggestions!
