Feature Request: Mesh Region

I'd like to put in a request for a Mesh Region tool.
Basically like this:

http://www.cgal.org/Manual/latest/doc_html/cgal_manual/packages.htm...

This can already be accomplished with the workaround of creating a Planar Surface and then using Mesh Brep, but it seems like meshing could potentially be a faster way to visualize and interact with the interior vs exterior areas of closed planar regions. It seems that making Planar Surfaces can be pretty heavy.

As an example of a use case where this is helpful, let's say I use a metaball component on a point grid with charges based on an attractor:

in order to be able to add any sense of solidity or fill to the interior of these shapes, the only way I know is to use Planar Surface, which takes about 5-8 seconds to solve in this case, and therefore seems a little bit heavy. It seems like meshing a region could be faster.

Of course if this already exists or someone has already made a great plugin, please let me know and disregard this request.

Thank you!

-Ben

It doesn't seem to be able to handle interior voids the way planarsrf can, but Mesh.CreateFromPlanarBoundary(Curve, MeshingParameters.Smooth) seems to perform marginally better.

I added an auto-conversion from Closed Planar Curves to Meshes:

So you should be able to accomplish this by just plugging the curves into a Mesh parameter come the next build. As Andrew pointer out though, there doesn't seem to be a mechanism to cater for holes inside boundaries, so it's strictly a 1:1, Curve:Mesh relationship.
