Problem with surface to solid body

m.maassenL5E7H — Fri, 20 Mar 2020 15:25:50 GMT

Hello all,

I am a new user of Fusion360.

I have a problem with a surface body not wanting to turn into a solid body.

Because of this I can't get the part to show up in my drawing.

I have searched on youtube how to do it but it doesn't seem t work.

I have some free edges wich are inside my part.

The method of using patch and then stitch does not work.

Does anyone have an idea how I can fix this problem?

P.S. I have already tried different tolerance settings

You'll have to attach your file here so we can have a look. But honestly I'm not sure why you wouldn't make this as a sheet metal part instead.

File>Export and then Attach your *.f3d file here.

This will be an easy one to fix.

Here is my file.

I have sorted the surface bodies in a seperate folder called "surface"

Hello Chris,

thank you for your reply.

i have attached my file below.

I imported this file from GrabCad, thats why it isn't a sheetmetal part.

Thicken will return a Solid Body.

I see.

Well, those particular edge must exist. But they are, in essence, the linear version of a singularity, and I think that's what prevents them from stitching.

However, since those shapes are "water tight," you can perform a Surface>Create>Boundary Fill operation on them, which will give you a solid part(s).

Other issues:

1. You seem to be organizing stuff as several BODIES within a COMPONENT. But those bodies seem to be separate, individual parts, so they should EACH be a component of their own. Do you know the difference? Learn the difference. You'll see me create the two new Boundary Fill operations with the option set to 'New Component,' and then go back and delete the related surface body (could have set the option to 'Remove Tool,' but didn't, so needed to delete them after the fact).

2. Technically, if those WILL be made of sheet metal, then they can't exist without a little spacing gap where those offending free edges exist, and it would probably be easier (unless you don't know how to do it yet) to just create them as sheet metal components to start with.

3. Why are you modeling without Capture Design History turned on?

Hello Chris,

Thank you very much for your detailed reply.

I am still learning the software, so all the tips are certainly appreciated.

I will try to learn more about when to choose bodies and components etc.
