Sheet metal 180 degrees bend flange

[pavmed]

Idea: add separate feature or special Flange behavior for 180 degrees flange bend

Purpose: to make injury-safe edges

Currently it takes two separate operations: 90 degrees bend with some unknown height, plus one more 90 degrees bend with needed height

First flange height is unpredicable - I have to put it unreasonably large and then edit feature to find minimum value when second bend still valid. Ex. in my case it's 2.1 mm for 1 mm metal.

Or one have to make it 179 degrees with Adjacent bend position and unpredictably large height.

In this example it's 140 mm height but only ~25 mm flange generated.

This is how I made it and the setigs I used 😄

Yep, that's exactly what I mean - you can do it but it requires some mumbo-jumbo to accomplish.

This is called a hem in sheet metal terminology and is either an open or closed hem. It would be very beneficial if 360 had a "hem tool" that could do this as it is a very commonly used sheet metal feature. In other programs, this tool is provided the length of the hem and if an open hem then the offset, the dimension of the opening between the two inside faces.

Please add a hem feature for sheet metal.

Image below shows the hem feature options in Solidworks. I don't have Inventor but pretty sure it has the same feature available.

A hem feature would be useful, especially with an option for flat or rolled hem, as per the SolidWorks screenshot above.

For sure, a hem option like in Inventor for example, will be very useful. 

I work allot in thin sheet metal, and drawing a hem in 360, takes allot of time.

Here's how to make a 180 degree flange (by using a contour flange):

- Create a sketch with a rectangle

- From that sketch click on the [Sheet metal] tab and press the [Flange] button

- Click the rectangle and then [OK] on the Flange popup to create a flat flange

- Create a new sketch by selecting one of the faces

- Press [P] on your keyboard which brings up the Project menu and click on one of the sides of your rectangle. It will go maroon to indicate that side is projected onto your new sketch

- Under the [CREATE] dropdown select [Arc][Tangent Arc]

- Draw a 180 degree arc tangent to the projected side of your flange and click [Finish Sketch]

- Extend the arc with a line parallel to your projected edge

- Click back on the SHEET METAL tab and press the [Flange] button

- Don't select the maroon side of your flange. Instead select the other edge tangent to your arc. Also select the arc you've just drawn and then press the OK button

Strange. It seems like I can post video here, but not screenshots?

@Anonymous i'm sure you meant well, but your steps are more than confusing: are frustrating. Would recommend to use fewer words and more images. Also, focus on the steps of creating ONLY the hem, because the rest of the flanges differ for each model.

I was looking for a solution to the issue, unfortunately I found your impossible to follow instructions. Maybe you would like to amend it, for other users to benefit of it.

Best wishes!
