Now that I seem to be capable to make solid from 3D surfaces I get stuck with filling the gaps between those surfaces to get a single solid from all the surfaces.
Any hint?
Or how to get a single surface from surfaces created separately. Like laying a blanket over a couple of items
Hi @Walter_Born
As always, it’s better to post actual geometry rather than some hard-to-read images. Also, what is your design intent here? is it a hard transition (similar to a beveled edge), a soft transition (similar to a fillet or blended edge) or is it to extend the existing surfaces and get a clean, single edge between the various surfaces? Depending on what you are looking for, you can use Loft, BlendSrf, FilletSrf or ExtendSrf, but please provide more detail, if you need a more detailed answer.

The backside gaps need to be closed to connect those solids.
In the end I need only the other side with the sharp edges as a mould for an item to be made from carbon fibre.
I want to print this as a mould for some prototype
Hi @Walter_Born
Here’s how I would approach this: I would start with just the inner surfaces and create the missing surfaces, in order to create an (almost, due to mismatched edges on the large surface) closed shape (those extra surfaces will be deleted later). Now extend/untrim all the surfaces, so that they have a little overhang. This is to make sure that we have clean and full intersections along all edges, since - as mentioned - the edges of the larger of the surfaces doesn’t fully match the edges of the sides. Now use CreateSolid (or Trim/Split) to get a single, closed polysrf. Now delete the surfaces you don’t need, and use OffsetSrf with the Solid=Yes option to create the thickened version - see video for reference.

HTH, Jakob
Will try that approach. Unfortunately cannot load your file in Rhino8
@Walter_Born
Sorry… totally forgot that I was using the WIP - my bad! Here’s the file in V8 format! The MO should be the same

Now that I see the result and have seen your video I will have to play back your video with at maximum 20% to see all the steps you obviously did in 2 minutes
So basically you extended all surfaces so they
overlap, then…ok, have to see the vid again
Hi @Walter_Born
Yes, basically just untrim all edges on all surfaces. Some you will have to extend manually using ExtendSrf - just to make sure that there’s a visible overhang. Then I use CreateSolid to create the closed polysrf. And then delete the not-wanted surfaces and OffsetSrf to create the thickness.
