Flat pattern of two flanges intersecting

[Anonymous]

Hello everyone,

I wanted to make a flat pattern of a shell (attachments: WC.ipt and Pic 1.png). The problem lays in area of intersecting bends. (attachment: Pic 2.png). Flat pattern doesn't work (errors during update). Thickness is set to 50 mm so it is not a thickness case.

So then I did a second try:

Sheet metal > sketch > surface > flange one and second edge, it shows me a good surface with curved line, but this surface isn't created after all. (attachment below, second post: Pic 3)

All I want to get is the template with K factor = 1 which I can use to actually mirror that curved cut on a actual steel plate. I have got a template but it won't work for me (attachment below, second post: Pic 4).

I will be very thankful for any help

HI!

If you want to flat sheet metal, it's better to use sheet metal tools:

Hi @Anonymous,

This does not work in Inventor, it is curved in two planes:

it only works in this Version:

 Hello,

I made your model flat pattern.

I have attaced the .ipt below so you can see how i did it.

Hope this helps?

Hello,

I also created it using contour flange.

Just showing you different ways you could model it.

And picture of the flat pattern.

Hello there 🙂

It looks very good, but I can't open the file. What is your version of Inventor?:)

======

I can see it now, 2018, do you have an older version? I am using a 2017.

Hello @Anonymous,

I have 2017 at home.

So when i finish work i will create an .ipt on 2017, and attach it on this post.

I have done a screencast for now, so you can see how i done it.

Hello @Anonymous

I have modelled the part in 2017, and attached it.

So you can open it, and see how to model it.

Hi MRumin, 

Note too that you can use an arc as the sketch for the flange, and use arc weld as the corner type to get the result you're after. Much like the previous suggestions, but it doesn't create a straight "leg" that requires a cut feature to remove.

I hope this helps.
Best of luck to you in all of your Inventor pursuits,

Hello @Curtis_Waguespack

I originally did the contour flange like you did.

But the height of the part that is in his model was 200mm. With 200mm Radius.

And when I placed the arc at 200mm radius in the sketch, it comes out 250mm in height.

That's why I did it the other way and cut it.

But the way you just shown is the better way to do it.

Thomas.

Hi @Thomas_Savage,

Ahh, good point. I didn't pay attention to the dimensions. 

Something like this sketch, and then using the top edges for selection would be the way to go then.

I hope this helps.
Best of luck to you in all of your Inventor pursuits,

Hello @Curtis_Waguespack

That's correct.

You have to connect the arc to the top of the steel, and not the bottom of the steel.

Else you end up with 250mm, like I just said. Because it includes the thickness of the steel.
