custom solid matrix creation on variable distance points

[AlessandroC.]

Good evening, everyone! !
they are again struggling with a solid/superficial transversal problem (I don’t know if this is the most appropiate section). .

I would like to create a matrix of a solid feature (in my case a cylinder extruded in the x axis with reference in the center of a face), repeating the object on very precise points (they will be the centers of the faces of the "copyed" cylinders).
These points should belong to a curve in space (in my case a 2d curve would sufficent, built on the plane of a face of the cyclic - yz plane) and be spaced between them with lengths commanded by a law.

Can any of you tell me if this matrix can be realized?
If yes, can you tell me how to define the various points on the reference curve?

I don't have a real file right now to train

thanks to who can help me

I'm not sure I understand if your "base" problem is to find the command that performs the solid repetition on the points you will define or if your problem is to space points on a curve according to a certain law.

In the first case, perhaps, the 'user pattern' command does your case?

http://catiadoc.free.fr/online/prtug_c2/images/dbuserpatternnls.gif

in the menus, usually, is next to the rectangular and circular repetitions.

in its simplest use, once you create the prism and define its anchor, in the pattern you just put the set of repetition points you need in a sketch and use it as 'positions' (if you create them with a curve on the sketch remembered, in the end, to turn it into 'built object').

Was that what you needed?

Then in the last versions (but I don't know why I almost never use it..... ) , they also added the possibility to use a multi-selection , so you can also use 3d elements directly (such as points or axes ) for repetition , giving more freedom to position , but I don't think it was your specific request .

Thanks for the answer.. .
the problem, initially, was general: I couldn't handle the "user pattern" command (it was enough, as you pointed out, to group the points in a sketch) and I didn't know how to space the points on the curve.

the first problem I had managed to solve it, exactly as you wrote above.
the second problem, of detaching the points in a parametric way, is still open:
I thought I could manage a distribution of points through a law, as can be done in many other commands (for example in the passage of a propeller,...), but I fear I miss some logical passage in software management.

It is also true that at this point the discussion should go to another section.
I look forward to advice from more experienced users to understand how to handle the discussion

Thank you.
