add more bends to rounded piece of sheet metal

I have a sheet metal part that I converted from a surface I create that forms a semicircle (top view).  Its 1/8" aluminum.  To form it we will need a lot more bend lines so that we can form that half circle on the brake as a segented half circle. 

 

How can I do this?  I have attached the file

If you are trying to "Bump" a sheet into a circle rather than roll it, you will have to model each bend to get bend lines for that.

 

Have fun adding many 175 degree bumps (I hate that they are not 5 degree bumps)

Understood.  Not following that last sentence though

The angle referance use for flanges is the wrong way in my opinion. A very small bend should be 5 degrees not 175 degrees when adding a flange.

Hi @lifofadrafter

 

 

Yes I am using ST10 but this function is there from v10 or even before.

Can't remember when it was introduced.

 

See video to do it Yourself - isn't really that problem:

@lifofadrafter,

 

As @hawcad shows, using lofted flange is easiest way to achieve this, the key "option" to use here is the "Triangulation" bending method, which allows the model to look smooth......alternatively, I have used a trimmed polygon sketch to get a real world faceted [using a lower bend count] contour flange [& lofted flange] in sheet metal parts.

Hi @SeanCresswell

 

 

 

trimmed polygon sounds great too.

 

Since the polygon function is there why not?

180 is flat, 135 is opened from 90, 45 is tighter than 90, 5 is almost closed.

175 is 5 tighter than 180
