Please help find a way to unravel the curved back to cut

BarrySumpter

Hi all,

I've been following this gentlemans' techniques for designing a tight mitre saw dust hood for my Makita 1216 DCMS.
https://www.youtube.com/channel/UCOk_5Ug8UF-qUO6C4Nh3lBA

I've designed a curved back that has a curved top.

I can't seem to find a way to unravel the back to layout a pattern to cut from 3mm flexible material.

Any positive constructive help would be greatly appreciated.

Could you share the SKP file of the hood?

Bob James

Just use the Rotate tool and rotate each segment until they are all on the same plane.

There is a plugin called Flattery.

Be aware that the low segmentation of your back curved wall will give you a shorter surface to wrap around the top and bottom surface.

I believe there was a plugin "Unfold" that did what you need.

Yes there was but sadly it no longer seems to be available. Flattery is, however, and it would work. It's available through the SCF PluginStore.

Alexander Schreyer also has a similar plugin, if memory serves...

I have jfUnfold.rb in my archive.
All Jim Folz links fail but it does work in SU 2015
Is it OK to provide here on the Forum?

Hi Dave,

Long time, no talk. Hope you're doing well.

I guess it should be up to Jim to grant permission to share his plugin. I don't know why his aren't available anymore but I would assume he has his reasons.

Cheers,

All is well here and I did find Jim's email and send a request to provide the script.
I know you are a boat person so here is my latest.
Just 30# and killer fast carbon fiber wonder.

Very nice! And light! I expect it's fun to get that going fast. No place locally to row and Lake Pepin is usually too rough.

It's an outdoor sport too

Dave #1 and Barry too
I got an email from Jim Folz and he is OK and happy to see the sawdust hood can find a use for the jfunfold plugin.
It requires both progressbar.rb and jfunfold.rb to work.
(see attached zip with both)
FYI it is an early and not polished but did work for me in SU 2015 pro
Cheers to all

Very good, Dave. I took the liberty of replacing the ZIP file with an RBZ version of it to make it easier to install using Install Extension from Preferences>Extensions.

Dave You are #1 and gaining on the crowd.

Many thanks to all.
Apologies for taking so long to get back here.

Thanks especially to the two Dave's for sorting this out.

Are there any further instructions on what to do once installed and executed?

As I didn't see any results.

Dave R

Barry, first, turn on hidden geometry. Then start it from the menu and click away on successive faces.

Wow, did you make that? Put an outrigger on it and it'll go in the rough water (with a paddle).
