And just to clarify on how you do the unwrap using curve flow, you have 3 pieces:



#1 is half of the top edge of the cylinder. This is the object that you will give as the object to deform, select it before running Flow.

#2 is half of the bottom circle of the cylinder. This is the base curve for the flow.

#3 is a line that has the same length as the half bottom circle, this is the target curve for flow.

Usually Flow is done with a straight line base curve onto a curved target but you can do it curved to straight as well.

This will be the result, it is floating above the line, you do the other halves in a second run of flow:

Aha!!!

Oh and for that line above, the #3 - you don't actually need to make it the line the exact same length as the arc as long as you don't enable the "Stretch" mode in the flow options.

When Stretch is off it will match "distance traveled along base curve" to the same distance traveled along the target curve, automatically extending if needed.

When Stretch is on it will match "percentage traveled along base curve" to the same percentage traveled along the target curve.

thank u guys.. now i need unfold sheet metal ..is there sript..

Hi 4rw1n,

> thank u guys.. now i need unfold sheet metal ..is there sript..

Sorry no none that I am aware of.

You might check out FreeCAD which has a sheet metal module, or Pepakura Designer.

Or the free FormZ Free ... https://autodessys.com/formz-free/

"""""""Or the free FormZ Free""""""""""

Can you show us how to unfold his part he posted with form-z free?

According to their web site here:
https://autodessys.com/formz_comparison/

It says that "Unfold model with tabs and labels" (under Product Design) is in the pro version, not in the free version.

Also I seem to remember it's not really for sheet metal, it's for papercraft type stuff like Pepakura Designer.

EDIT:

Looks like it can do also NURBS unfolded as NURBS when there are developable surfaces. So that might work ok (in pro version) for sheet metal models too. For polygon mesh objects it does Pepakura Designer type stuff with making tabs.

Hi 4rw1n,

please find attached "unfolded" file, where you can find unfold part.

It has been used flow command inside MoI by technique described here:

Flow as Unfold tool !

Hope this helps.

In free version that this sort of Unfolding





Unfold : Last function on the right!











So must convert 3DM in OBJ for example

So ;) Remark that NGons are accepted!
Maybe not the same result wanted! :)

Hi Pilou, is that the current Form-Z free version that you are running there?
(https://autodessys.com/formz-free/)

Or are you running the bonzai3d app which I think has been discontinued?

- Michael

@Pilou,

re:
> Maybe not the same result wanted! :)

No it doesn't look like the right kind of result. It looks like that's the polygon model unfolder for papercrafting, not the NURBS unfolder.

- Michael

No it's the FormZfree that I have downloaded some few month ago maybe not latest version...
Latest is 10.1.5 (B27E) against mine 9.1.0 (Build A 399) ! :)

UI is falsely "friendly" ;) It's for that i did not yet made a page about it! :)
Multiple pannels to regulate... but some cool tools integrated... stairs, roof, terrain ... like SketchUp but without plugins!

Yep...
Last Free version installed! :) 10 . 1.5 Build B27E Surely some bugs treated...

It's an "Ascis" Kernel product ...



It's the same in the free! But of course not that you want! :)

So the answer is "No"....

And it DOESNT do Sheetmetal unfolding....

Got it....

Yes! :)

Else in general More Subdive than Nurbs.... better than SketchUp without Plugins
Not so bad for the price! ;)



Can be a cool speed subdive protototyping for some things...
