Hello
I have a small problem because I can't create an axle on a cylindrical opening from a rolled sheet metal.
I started with a sheet of metal that I unfolded and made an Ø84 in it, then I folded it back. Pb once folded no way to make an axle in this hole, but I need it to constrain other parts.
Thank you for your help.
Hello
I'll do it like this:
INSERT --> REFERENCE GEOMETRY --> AXIS then you take a as a first reference the center of your drilling (in your hole sketch) then as a second reference a plane of your part that passes through your hole and thus you will have your axis.
if you went on the unfolded to make the hole
it is normal that you cannot once bend to have this axis
since visually it's no longer a round hole
but an ovoid shape
A walkthrough would be to create a sketch in a front plane or other
and to make a construction line to this said axis

GT22: I tried to make a sketch but I can't get any construction points, so impossible. What I don't understand is why it can't find a central axis on the created cone?
TicTic: I'm going to try flat and see if the axle is kept once the sheet is folded!!
Hello
When displaying the temporary axes (T key of the keyboard by default) the axis of the hole does not appear?
Show us a picture of your piece
what version do you have of SW

Why do it flat?
If you do the trick I gave you on your folded piece you won't have a problem.
I'm looking at it right away but it's hard to rebuild...
a moment thank you...
Version SW2015 SP5
Here is my rolled sheet metal:
no, the "T" key doesn't work.
Tictic: It doesn't work in the sheet metal I don't have access to my sketch, in any case I can't do anything with it
quite tictic... but I wonder about your method.... I can't do it.
Can you make a screen print when creating the axis?
So I start with a rolled sheet metal.
I do my drilling on the flat part.
Then I fold my piece.
Then Insert --> geo reference --> axis
You generate the axis from 2 shots like on my PC. Your plans must of course go through the center of your drilling. Recreates plans as needed if the base plans don't match.
yes Tictic I understand, but in your case it's simpler you took the 2 reference planes (right plane and front).
Now on your flat piece, shift your hole from the longitudinal axis and try to do the same thing. A plan will always be easy to make because it will have a rib that starts from the edge of the sheet metal but for the other one you end up on an angular offset...
In this case, you need to recreate a plane with your angular offset that is fine, and then from this plane you recreate your axis. See PJ TEST
However, I'm thinking about it: you would certainly have been simpler from your rolled piece to make a plane tangent to your outer surface and then to do your drilling. This will make it easier for you to make your axis normal to this plane. (see PJ TEST 2)
The problem is that I need my sheet flat to do the laser manufacturing at the suppliers, so I need round holes once the sheet is flat.
Otherwise I had thought about taking the hill flat and deducing the angle, but despite everything it is not as precise as actually going through the center.
I think that in the end I will resolve to do it this way.
Thank you anyway
If you do as in TEST2, when unfolding your part, you will have round holes for laser cutting, I don't see where the problem is at this level
Hello
I have a MacGyver solution, it may not be the best but it can help.
may the force be with you.
