Sheet Metal - Planificação unidos.

I cannot plan all the sheets together. Sheet Metal.
Can anyone help?

Is this an Inventor Nesting question, or can you elaborate on what you wish to achieve?

I want to carry out planning, as per the attachment.
I need to carry out IAM planning.
I transformed the iam to ipt.
Ipt flat pattern.

You've asked this before. The same methods still work.

Do you plan to weld it together before rolling it? If that is so, you need to derive the assembly into a part and select multiple parts and merge them to one solid.

on the screenshot below I derived the whole assembly and connected it appropriately to unfold the whole thing.

kacper.suchomski ,

Your example was perfect, I understand.
I've already used your work.
In that example there was only one plate in diameter.

In this question now, there are several plates in diameter.
I couldn't apply the same idea.
That's why I asked for help.

YannickEnrico,

That's exactly what I need.
Is it possible to make a video?

Thank you all for your help.

Hi @iva.btblan

I'll attach the project. I don't have the option to record.

The workflow is as follows:

1. Derive the assembly into a part. Select all solids. If you want to keep colours, make sure to select the highlit option. Otherwise you can choose the first option where it doesn't keep edges.

2. Each individual ring needs to have an opening, or they won't be able to be unfolded. You can't use rip if you keep edges, so instead I'm using a "pizza slice" to make sure I cut perpendicular to the plate thickness

3. Now you need to connect the three layers, because sheet metal will only unfold anything that is connected properly. If you don't do anything, you'll get an unfold that looks like the first screenshot.

Screenshot 2 is the workflow I've used to connect them
Screenshot 3 is the resulting cylinder where you can see the yellow plates are connected.

I'll attach a ZIP file with your files and my solution.

Yes you can.

The method with model states works regardless of the number of plates. The way we create states for flat patterns and connect them to assembly state remains unchanged.

The only difference is the number of clicks you have to make.
Since you have more plates, you will have to define more join/constraints. You have to sit in front of the screen and click - that's the whole art.

Look at this:

You can do positioning in the model states method in two ways:

Proportions resulting from the angles of the sheets and the angles of their mutual position (in the video)
Create a sketch from the face side and sketch an arc between the plate boundaries. The arc must coincide with the neutral axis - move it away from the internal surface by multiplying the sheet thickness and the K factor.

And there is a third way 🙂
