My surface offset creates 2 bodies and does not close

Hey there. 

I extruded a shape which I wanted to create an offset of. But the offset is a) creating multiple bodies even though it's a chain selection and b) does not cover all of the original surface. You can see in the picture that the top right corner is missing.

What is wrong here and how can I get the offset to create a complete surface?

 

Export is attached


Thanks

Using some Construction planes and Axis, I decided to let it do the improper offset and then rotate it into position. I was then able to Stitch them all into one Surface:

Your emboss is leaving this sliver behind, do you want this? Seem to remember emboss does not like creating closed or overlapping features.

Because of this your next body has a gap, again do you want this?

Oh interesting. I didn't see that. And no I dont want that.

 

I used the loop length from the inspection tab of the surface for the sketch I deboss. Guess here is some rounding error going on?

 

Thanks for your help. Appreciate it

If you don't want the sliver and gap, split face amd press\pull is a better option.

All works correctly done like this, see attached file.

Update: okay thats working of course because I can use a surface offset from there on. But then I have the issue, that my inner offset isn't round anymore??

old message:

 

Unfortunately that's not working for me - I think.

 

I want to create 2 separate bodies eventually which will look something like this

It's meant to be 3d-printed and put together. So I want to deboss the red part first and then create an offset from there which I can thicken back to the debossed surface ("extrude" it as new body if you want)

 

When I do it per split face + "q" then I cant create a new body. Hope that makes sense

That's only because the offset is more than the corner radius. EIther increase the corner fillets or decrease the offset.
