Management of sheet metal bodies

[javiermirandapuente]

I created a new design intended to be a sheet metal assembly. My usual workflow when starting from scratch is to create multiple “objects” within the same design, reusing already-created geometry. In other words, a multi-body design.

In the current version of Fusion, when I started the file I selected “Design” (part design / single design environment). On the first extrusion, I converted that body to sheet metal using the corresponding command. Then, for the next extrusions, I had to choose “New Body” because without Hybrid Design enabled, you can only work as a single design (not as separate components). In the end, my design is structured as shown in the image.

The problem is: I can’t really do anything useful with it now. Flat patterns can only be created per sheet metal body, and I can’t have multiple flat patterns at the same time (which is not viable because I would have to keep deleting/suppressing previous ones). When creating drawings for each part, I can’t generate the flat pattern for each sheet metal part.

At first glance, I don’t have a way to revert this. I tried enabling Hybrid Design, but it still won’t let me convert each sheet metal body into a component (it literally won’t allow it — Fusion says the operation is not compatible with sheet metal bodies). Also, if I roll back the timeline to the point where the extrusions were created, the Extrude command does not show the “New Component” option (only New Body / Join / Cut / Intersect). However, for new extrusions made now, Fusion does show options related to components (which makes no sense to me, since it doesn’t help with the bodies created earlier).

So, I’m stuck with a design I’ve spent several hours on and I don’t know how to proceed. Any ideas or best practices to fix this and be able to get separate flat patterns/drawings for each sheet metal part?

Hi

Even hybrid mode doesn't allow you to convert multi-body sheet component to separate sheet metal components.

You simply used the wrong modeling strategy. 

You have 2 options:

1. Create a new hybrid design and work with components correctly.
2. Output individual bodies to new part files using derived geometry.

2. You should have converted at this step.

Save as STEP.

Open the STEP and Create Components.

Conver to Sheet Metal each Component Body.
