straighten the inner face of a cylinder with the trajectory of a concave curve

[Entità_vettoriale]

Hi, I have the problem that I should rake the inside face of a clindro following the trajectory of a concave curve, but I don't know and don't understand how to do, I've been looking around but nothing.... how can I do?
Alternatively, I tried to extrude the triangle (with concave hypotenuse) through circular trajectory (turning theucs), but it tells me that it is impossible.. Why? I attach image where you see object 3d and curve line disengaged within the thickness that I should extrude. .


thanks in advance.

@scale_vettoriale:
Alternatively, you could perform a boolean subtraction by generating an internal solid to be subtracted that has the profile of your curve.
even if it would be clearer if you post your dwg, only the detail is meant! that gives you problems, the causes could be multiple: First of all, the fact of touching the ucs! but instead of changing the ucs, did you try to rotate the solid properly?

the Boolean subrazioen I do not know how it is, if it is the normal subtraction of two solids, the problem of extrusion through concave trajectory is similar.. .


thank you for the answer cmq...

I attach the file as required.

Could you excuse me at least post it in 2007 format? Thanks I have problems with the chin! Excuse me... again.

sweep, select the poly and then circle as path.

here is the file in 2007, now I try as it says gp, thank you in the meantime for the answers, then I let you know. . .

fantastic!!! thanks gp :36_1_13:

in fact with the sweep it works: here it is!

 

[Entità_vettoriale]

Yes, thank you.. to know... The sweep icon, where do I find it? besides the sweep command to type I mean. .

 

[Ezio Olivato]

under the design/modeling menu:, otherwise you must set it.

Thank you all.

prego....e di che!
