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.

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.
