Good day.
This is items is out of Nvil3d object import then subD this was cut out of the object ...the surface selected.
I would like to get this thing thicken or extruded because ti will need to make frame for it.

How to proceed with something like this?

Tnx!

Hi Matadem, select it and run Construct > Offset > Shell.

Note there will be some little sharp pieces where the surfaces are not smooth to each other.

If those surfaces are coming from Nvil3d, make sure the vertices where faces meet are welded and shared instead of duplicated. Vertices need to be shared between 2 faces for them to have smoothing between them.

Several methods are possible.

They don't all give the same result.
So you choose based on what you want to achieve.

First possibility I see
- Select your object
- Construct -> Offset -> Shell


Second
- Select your object
- Copy / Paste to have two surfaces
- Move one of your two object
- Select all external edges of your two objects
- Edit / Join it will join continuous edges and create 2 closed curves
- You can Construct / Loft between those 2 closed curves
- Next select your 3 objects top/bottom sufaces and the lofting
- Join then to have a solid

If you test those 2 methods, you could compare, see, and undersatnd the differences between those methods to choose the best for your case.

I think it exists many other methods but with those you have a first choice.

Have fun

or...

Thanks going to try these out.
