Hello
I would like to know how to create polygons on a given surface like on this 
And to be able to add a different material from each other.
Thank you!
Good evening
You'll have to have a little fun, look at my tutorial and use the beginning (up to page 7) to make your little pyramids of different shapes. it also works with a triangle as a base...

Thanks for the tutorial, I'll look at it.
In fact, I want to make a patchwork of this kind for a table on a 2 mm thick sheet of laminate with fewer pieces.
Ok so you want to achieve a visual effect and not have relief.

Patchwork can only be triangle marquetry without volume, or with a slight volume by putting certain elements of marquetry a little higher.
But apart from marquetry the possibilities are limited knowing that in laminate it is not possible to do thermoforming.
Rather than laminate it would be better to proceed differently: but specifying beforehand as @Ac cobra asks :-) if the triangles have volume or remain flat.

Yes just position my pieces on a panel, so there will only be the thickness of the laminate.
In this case, all you have to do is make a sketch and:
- take a screenshot and use the image as a template
- Or make an overall sketch of a few dozen triangles and then an extrusion by scoring a space of 0.1 mm between each triangle to have something usable and modifiable according to the effect obtained.
- Then have a PDF file saved and printed to use as a snapshot to draw the tops of the triangles.
- Either you make a 3D drawing and you print it to use it as a cliché or you save the MEP in PDF and print it to use as a cliché.
The other solution is to trace the back of the laminate but it depends on whether your laminate is plain or if you want to make it like the photo with different colors.
Kind regards
Hello
Actually the idea, if possible, is to make a rectangle and draw lines to create the polygons. And then make them independent, to separate them.
I think this is not the right way to go about it because if you make a rectangle or a parallelogram (another function available for drawing) you will have either automatic squareness or parallelism relationships. Which you will have to remove to do your tricks.
Moreover, from the little I have understood of the geometry of the triangle , even if it is any, it is that it has only three sides: which means that with a sketch of a parallelogram you will also have to remove the superfluous side.
The easiest way is to make straight lines but the purpose of the forum is perhaps not to explain how to make an ordinary sketch. What also matters is how to go from sketching to tracing on the laminate or an automatic cutting (to be seen)
With the information already suggested, you should at least be able to draw a line on your material.
Kind regards
Good evening
I don't really see how to do it, I can create my triangles with the line function but once I extrude they unite, how to create a separation between each line?
It's normal You have to put a space between each line.
I am even surprised that the sketch is accepted (?????)
In other words , you have to make a first triangle and then make another one next to it (so two triangles that don't touch)
The two adjacent sides must be parallel (second triangle parallel to the first triangle) in order to be able to dimension
Then put a rating of 0.5 or less. The width depends on the cutting tool: 0.1 for laser to a few mm if CNC cutting or 0.2 to 0.5mm for the width of the scroll saw.
Don't forget the attachment points, at least three or four per triangle. Otherwise you won't find your way around the pieces, not to mention the trapping under the head that will make the cut and all the damage it will cause to your parts.
Can you mail your file please
Last remark (which I already made before) as long as you don't say how you will make your cut: it will be difficult for us to give you advice or suggestions
Kind regards
Hello
It doesn't seem to me to be an optimal method, I think there is a way that should allow you to do this kind of thing.
Here is the file

Good evening
The basic element of any 3D construction is a sketch.
From this sketch we make either a surface or a volume. and so what!
However, I notice that you still do not want to answer our questions and do not seem to take our comments into account and that you seem to doubt the method we are proposing.
You are much too strong for me who am much more beginner than you and with my few burnt out neurons: I could not be of much help to you.
As a result: I withdraw from the discussion and wish you speedy success.
Kind regards
PS: If someone is able to directly make a volume or a sketch file usable outside of SW with cutouts without spaces between each stroke then this is the solution. In addition, the expert capable of this feat will tell us out of kindness and compassion: what tool he will use to trace and/or cut the laminate. That is to say, which file must be produced to make the cut. Humbly yours: -)
I take note, I'm just saying that it's not the easiest, but I succeeded.
I used "Offset entities" and then added between the 0.1 mm lines by checking the bidirectional option and voila.
Here is the file:

You have succeeded, it is good, but it is a pure miracle when I see how you have managed to achieve this.
In addition, there are defects everywhere, hello the tools behind to make the cut.
For us who are SolidWorks pros and especially some if they see the result will have hair growing in their heads.
In addition, we are very, very far from the image of your first post.
Kind regards

The image was just to illustrate, I would make triangles much bigger.
Indeed I understand my junctions I think it's due to my tracing I'll start again to see.
For the tools, it will be my hands, tracing and then cutting with a circular saw.
Yes, when I choose my parts to extrude it takes on some up to the drawn line and not the one that is offset.
Part1.SLDPRT
The solution is the following without lagging!!
make a boss of the whole surface then draw a sketch on the boss with the construction line of all the triangles, then create a sketch for each triangle by converting the lines of a triange into a construction line "you will have 1 sketch in the construction line, and as much sketch as triangle"
1) use the split tool which will allow you to make a multitude of contiguous parts that you will save in an assembly file by saving the bodies
2 each piece can have its own material, a bit fast but the basis is to break up the piece, the advantage is to keep a sketch in line of construction that you can modify at will

I don't understand how you create sketches from triangles in the construction line. A sketch for a triangle?
And why convert afterwards?
Is there the website to do that?
Hello
The technique proposed by @contact_94 is simple.
It looks exactly as if you were tracing with a pencil or a tracing tip on the back of your laminate (if you're a professional).
In short
1°) The extrusion corresponds to your laminate sheet
2°) The sketch corresponds to the tracing
3°) The dividing line is a function that allows you to divide the surface (as if you had a band saw.) It is this separation that allows the next tool to work.
4°) The "split" tool corresponds to what the band saw physically does and to the person who saws.
I note that despite our repeated requests, we still don't know how you go from SolidWorks CAD to plotting on laminate.
~ Do you go through an MEP???
~ What do you do with the plan once you have the MEP???
Especially since we also don't know the size, length and width of your laminate. With an A4 sheet, you don't get very far.
In my opinion, the question that remains incomprehensible is why use SolidWorks to make a cut with a band saw at the end.
