flat pattern failure

I'm trynig to design a launder and get all the plate into flat patterns for fabrication.

Problem is, I can't figure out how to get the sheetmetal module to flatten these parts.

I tried making them about 5 different ways, but no success.

Anybody have any idea how to make this work?

See attached files.

Much obliged ... Chris

Hi Chris,

I think your design approach is way too complicated. Try to simplify it. Here is a part which unfolds as expected.

Regards,

Igor.

Thanx Igor.

I ended up doing it the way you showed.

Same w/the bottom piece (see attached).

However, the problem is, I need to get that chamfer along the bottom edge.

Note that your side doesn't meet up w/the bottom curved chamfer.

Also, I can't get the bottom chamfer to flatten.

The reason is b/c it's not flat (it's 3-dimensionally curved).

It needs to be a 'cone'.

Basically, I need to make flatpatterns of each part of the "LoftSurf1".

It's still a puzzle to me.

Any ideas how to do that, esp. that corner chamfer/cone?

I have an idea to try today, but not sure if it's going to work.

Igor,

Find attached what I was talking about in my last post.

The thing is, I need that btm inner chamfer, but can't work on it till later to see if I can come up w/a solution.

This is only one branch of a larger launder, so I like to break things into sub-assemblies if possible, like you see in these files.

Anyways, thanx for your input ... Chris

Igor,

I think I answered my own question.

Your input gave me an idea and it worked.

I just did a planar Sweep of the corner chamfer that's on the main Sketch, then extended it past the bottom plane, and then trimmed it to the bottom plane.

Then I trimmed the sides to those bottom chamfers.

Maybe b/c I don't do too much of this surfacing is why I got all 'dazed' over this challenge.

Anyways, w/your help, I got what I wanted.

Thanx for helping!

Igor,

Find attached what I ended up doing.

This is the only way I found that would allow me to update the wireframe part file, so these parts would update w/o breaking, and give me flat patterns.

Looks like a lotta work, but it's really pretty simple.

The key was keeping "on-plane" and "parallel", and using "work features" instead of "derived" edges (which break all the time in 2d & 3d sketches!).

Hi Chris,

Thanks for sharing.

Yes, sometimes it might seems as too much work to get something modeled, but then again - it will require some effort to fabricate the item too. And if you have a reliable record of the design - then return on investment will be seen pretty soon.

Best Regards,

Igor.
