V8i - Fill Surfaces as Solids?

I recreated the side surfaces to the "Slide" as I do not believe the existing ones matched. Having recreated I then selected all the surfaces and used the ' Stitch Surfaces ' tool to join them and convert to a solid.

Thanks Max!

This is very very close and I think I can use it even though it is ever so slightly different than the original.

I don't know how you used the tools you listed to achieve this. It's great to have the model, but I wish I knew how to do it myself.

Hi JJ,

I agree - a "fill between surfaces" would be a useful tool.

I've had a go at creating the slide using the standard "thicken surface", "fillet edges" and "subtract solids" tools, with fairly accurate results. See attached.

Thanks again, but as I mentioned I actually already tried this. Unfortunately the geometry of the slide is such that this tool does not produce the desired result.

What I am really hoping is that there is a way to "fill" an area that is bounded by surfaces, but I have not been able to find a way yet.

Ah, understood.

There is a command called Solid by Thicken Surface that can... well like it says, it thickens a surface and makes it a Solid.

See the screen shot from V8i SS3.

Thanks for your response, but this is not my issue. I'm not concerned with the visual appearance.

As I am sure you are aware, MicroStation has both surface and solid element types. In this model the cylinder is a solid, but the "slide" around the outside is made of several surfaces (i.e. it is hollow). I need to model the slide as a solid. It has to be a solid element.

I've tried to thicken the surfaces to solids, stitching the surfaces together and trying to use them to trim the shape from a solid, and many other failed attempts.

You have applied a Display Style called Transparent Modeling. On your keyboard hit CTRL+B and a menu called View Attributes wil appear. If you change Display Style to either Smooth or Illustration, you should see filled objects.
