problem with holes in the sheet metal environment

[sweeping]

Hello, everyone.
use pro/e wf2 for several years (I know, it is now obsolete but this passes the convent). I mostly work in the standard modeling environment but occasionally I have to use sheet metal. I ask therefore in advance veia to those who eat “lamiera” at breakfast if my question should be trivial or if I mistake some elementary passage.
I describe the problem: in the standard environment with a thin helical sweep I create a sheet of a certain thickness. then practical of the holes in the curved part and step to the sheet environment (if necessary adding a straight part to the helical sheet, otherwise it does not convert).
since the sheet has to finish under the laser cut I need the development plan then through the feature flattening everything out. I put in the table but the holes of the curved part are spline. I ask if there is a procedure or anything that can maintain the precise diameter of the holes even after the operation “flatten”.
I thank in advance anyone who can enlighten me on this matter.

I am not able to help you with the 2 because I have not + installed it.
from 3 onwards though I can tell you that there are several options when you cut, one of these is the normal cut to the surface.

Otherwise you could create a feature of unbend do the holes you need and fold the sheet again, so you're sure that the hole is real for laser cutting.. .

First of all, I thank you for your answer.
I can't do holes when the sheet is spread because the references I only have them when the sheet is curved. even if I try to put some points of reference where the holes will have to be when laying the plates the points do not follow the sheet but remain in "air".

but don't you have a file to better understand?

Okay, as soon as I'm free, I try to post something simplified but that can make the idea.

place a simplified part that should make the idea of the problem. However, as mentioned above, the holes must be executed before the unbend, as their position references only have them when the sheet is curved. ask again if it is not clear yet.

Good morning, every now and then I'll make it back alive.
I'll give you a solution.
in the generic (folded) keep the holes with the correct diameter (ø5)
in the developed variant reduces the hole ø (example 1) and uses it as a reference for a new cutting feat with the exact diameter; for sketch references you can use the two vertices of the ø1 circle.

Yes, in fact what you say cletus is what I do now but differently: I carry the part in dxf and then I take the holes in autocad. Of course, with your suggestion I can do everything inside proe and avoid to involve colleagues using autocad.
