Hi,
I am having a big problem.
I have hole on cylinder at equally distributed over surface. I have to wrap that cylinder with sheet metal as in attached file and also have to match the holes on rolled sheet metal to the holes on cylinder.
if I make holes on flat pattern at equal distance, it won't match to the holes on cylinder.
if I make holes on rolled sheet, it won't be practically possible.
So please suggest if there are better way to punch the hole on rolled/bent sheet.
Thanks in advance.

Hello Reeshi,
Don't worry, you are not bothering anyone. We help because we want to help, it's not a bother, lol. I'm just saying that if you want to get a very good answer, it's better to give as much description as possible so that we know what the problem is.
Here's a very fast and easy way to dimension without using reference geometry:
Place your flat pattern view and then draw a sketch on top of it making a bunch of lines that connect all of the holes together:
Then just dimension to the end points of each line segment.
When you're done, just hide the lines.
I use lines to emphasize that this method is a fast way, but not the best way. You can make better lines that look like centermarks if you wish, but lines is just faster.
