Sheetmetal recreate a part - non symmetric flange

[goblinn]

Hi,

I found a challenge for myself to draw the attached part in f360, but I am stuck with all the ideas I had. I am attaching the f3d file in the last step I would expect from f360 to be able to connect flanges (+mitter) together.

Tried also what is described in the post (Sheet Metal Flange - Creating non-symetric flanges)
Creating a model + patch + thicken material => flat pattern

How would you draw this in f360?
(Files named expected - those ones were drawn in OnShape)

First thing I notice is that you did not make use of obvious symmetry about the origin (but the OnShape designer did do this basic step).

Are you familiar with the 4 rules of sheet metal?

I don't know about those 4 rules. Your help would be needed here. Could you list them or give a link. I would love to learn and apply them all.

[TheCADWhisperer]

Start a new part file.

Create Sketch1 as shown.

[TheCADWhisperer]

Create Sketch2 as shown.

[TheCADWhisperer]

Extrude Sketch1 by width of Sketch2.

Extrude Sketch2 through all - Intersect.

Attach your *.f3d file here for next step and video on how to complete.

I am attaching f3d with intersection made. On shetch2 I am not able to add horizontal rules as you did.

You have a Perpendicular constraint to the projected line - so identical result.

Turn on your sound and watch this video.

See if you can adapt this hybrid modeling technique to your part.

If you have trouble - post back.

I tried to apply the rules but I think I am missing something when I am adding fillets or removing them.

I attached the file, could you give me a hint to move further or mark where should I investigate more time.

I think I can't apply properly 2nd rule? Bends are cylindrical or canonical

Thank you

@TheCADWhisperer

Any suggestions how to continue on their this? I don’t if I took right approach?

[TheCADWhisperer]

I will take a look at this and get back to you tomorrow.

I found the problem and I think it will be easy to fix.

If you don't hear back from me - bump it back to the top.

[TheCADWhisperer]

OK, I was able to get a flat pattern, but I want to clean up my solution a bit before posting.

I have to run, so check back later for my solution.

(I was surprised that these guys didn't get into anything other than the most basic of techniques.)

Looks good

I am looking forward

There are an infinite number of possibilities on how to trim away the double curve intersection (see attached) that would depend on available process tooling for cutting the Flat Pattern and Design Intent. 

After giving it some thought - I could probably simplify this still further into a single Split Face feature or Trim Surface feature instead of two features.
