Dear All,
I want to convert a surface into shapes. Is there any options available in Microstation-V8?

but will that work with 3d ... not all strings are planar ....??????

It will work with 3d, but the result will be a planar shape. It will only create planar shapes.
Shapes are inherently planar, so if the input surface is non-planar and the desired results are non-planar, the result would be multiple shapes, or facets, approximating the surface. Since Dharmarajan's sample shows a non-faceted shape as the desired result, I chose the Create Region Flood method.
Hi Ron,
Unknown said:Shapes are inherently planar
It's not true. The only shape, which is always inherently planar, is a triangle (shape with 3 not coincident vertices). Any shape with more vecrtices can be planar, but it's not ensured. E.g. a border of ruled surface can also be the shape, but it's not the planar geometry.
In MicroStation, the shapes created by facetization, are planar shapes.
With regards,

guys, to be honest, from that screenshot I'm not able to tell if the shape is planar or if surface is even developable ... so, there are various option how to create shapes from surface. anyway, in real world scenario I'd suggest some serious paneling tool

FWIWWhile it is true that it's possible to create a non-planar shape, MicroStation shape elements are intended to be planar and the tools for creation and manipulation generally enforce this intent. (More info on shape planarity)
