Knockout in sheet metal

[L.Maas]

I am not sure if the term knockout is the right one. I am trying to create a cutout as in the attached part (later to be used as a punch). Basically a cutout that is then folded as shown.

Problem is that when I cut the part I have to create a new solid body otherwise it wil immediately join with the plate again.

When folding it does not stay connected properly (see arrow). Modifying settings often results in that the plate folds instead of the knockout.

What is a better way to make this?

Hi Louis,

Or you think your part modeling ina  difefrent order or as a first solution it came to me this (i didn't check your exact measures).

Sheet metal is not my daily bread and butter, i am sure someone else will give you another smoother way.

In the meanwhile:

Note that you created a second solid body.

I recommend that beginners (or experts) should almost never ever use the Fold command - model in finished form instead.

Thank you both. I will get it to work.

JDMather, why do you say we should never use the fold command? What is the issue with this command?

[JDMather]

There is no issue with the command.

The issue is with users not understanding how and when to use the command.
