hi is possible unfold pipe metal in moi like in picture

also i neeed unfold sheet metal.. if there options and script please help

You can Unwrap curves!

Flow as Unfold tool !

Hi 4rw1n, some info on using the Flow command for unrolling a cylindrical surface here:

is there any tutorial for making it.. i dont understand..

thank u but this dont help me i dont know what tool u use. is it script or what?

One thing I use sometimes is https://pepakura.tamasoft.co.jp/pepakura_designer/download/

Draw in Moi import there and get the templates. it is quick.

You also have https://www.bend-tech.com/software/
if you need to do allot of roll cages it could be worth it.

It's just Flow function but alas that works not good with complete cylinder!
In my example that is not a complete cylinder so works fine!


Use : Copy Past in place the top external arc Cylinder (will be the Base curve)
Look at Detail (up page right for have the length of this arc (will be the target line - the same than the script Unwrap Curve )
Draw a line of this length : the Target line

Select the object Cylinder with the window
Call the Flow function
Click the arc Circle (pasted) as start curve
Click the target line drawn
Et voilà you have your unfolded object! ;)

THIS WHAT I NEED I DRAW IT MANUALY BUT I THINK NOT CORRECT..
i need only lines for paper template..

Hi 4rw1n,

> THIS WHAT I NEED I DRAW IT MANUALY BUT I THINK NOT CORRECT..

Please post the .3dm model file with those objects.

Here is a quick "Curve to Curve Flow"



If you rotate the object, you can get the curve to unwrap the way you show. Depends on how you want the edges to cut...

THis is the rotation i was talking about to get the edges you want for a cut

Wish Moi3d will get unfold surface or 3d model unfold options in the future.

@Burrman fell across your YouTube channel. Amazing. Are you possibly available for custom video tutorials? Cost? Thank you!

Hi Nate,
Sorry, i don't do that… hope you find something.

somethimes i cant separate line

The line is a single entity folding over on itself with no segments. There is no "separation.

I am not sure how to arrange to Unfold that particular shape. For me it is starting to get into the non developable arena and want to go to software meant to do that.

Maybe Michael can direct unrolling that cylinder?

Here is a video where I use Pepakura to unfold it. But you are now "dicing up your model". So you will have to make a determination on tolerances and accuracy

Hi 4rw1n,

re:
> somethimes i cant separate line

It looks like using a closed curve for the base curve is problematic because a point that maps onto the seam point of the base curve is equally close to 2 locations on the unwrapped line.

I think you can solve this by splitting it in half and processing each half separately:







- Michael

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!!!
