Embedded bodies

Anonymous — Mon, 12 Sep 2016 18:39:39 GMT

All,

I'm working with Fusion360 at the request of a few customers, and am trying to determine if I can model solid bodies within each other.

This may seem a strange concept to you, but there's a reason. Working with the Voxel8 Developer's Kit 3D Printer, the custom slicer automatically creates the gaps necessary between embedded components, silver conductive ink, and thermoplastic.

For complex electronics, it can be quite a lot of work to model the channel or pocket the silver ink or component will sit. It is entirely possible, but if I were to fully utilize the slicer, I would just have to include the silver ink or component as a separate solid body and let it handle the rest.

My question then, is whether anyone has a method of embedding solid bodies within each other, or if this is even possible in Fusion360?

Thanks,

Kasey Smart

Hi @Anonymous,

So, are you talking about physical embedding, as opposed to logical embedding, right? If so, there is no problem doing this in Fusion - a body's geometry can be completely enclosed inside another body. I can provide a quick screencast showing how to do this, although it might not match your exact geometry, if that will help

Jeff,

Thanks for the response.

I'm not entirely following what you mean by logical vs physical embedding. I do still need to maintain a constrained position within the other body to route the circuits being designed.

The other day, I tried creating an additional component, though ran into an issue where Fusion wouldn't allow me to extrude my new body into the other solid body.

To illustrate what I'm doing, see this image: http://support.voxel8.co/hc/en-us/article_attachments/203353153/45_created_traces2_resized.png

The two geometries visible on the upper and lower surfaces are embedded conductive traces. In Fusion, I sketched the lower portion of the trace for extrusion, but I could only extrude that which was outside of the body, not the interior portion of the sketch. I hope I'm being clear enough to paint a picture.

Thanks!

When you do your extrusion, just be sure and have the new body option selected.

Something also occurred to me while I did this Screencast... if you don't have your selection filter set to "through" you wont be able to grab sketch entities that are embedded. Take a look and you'll see two ways to do this... one is to discreetly extrude everything and then combine. The other method is to hide what you don't want joined together.

Thank you Kenny, that explained everything excellently.
