Problem about simplifying the curve for metaball.

Hi guys, this is what I did in my studio.

Can anyone help me to rebuild the curvesssssss. I just cannot do it for so long, Cannot close the curve even I used the method of divided curves.

I found some problem about the curve as I found many polylines after I extrude the planar up.

you can rebuild your metaball curves. not sure what's really happening since nothing is visible in your images...

Oh, You cannot see my images uploaded? the metaball contours are formed by polyline so there will be so many vertical line after I extruding it.

Yup, [Rebuild] or [Fit Curve] will create a smooth nurbs from your polyline.

Another approach is to extract the polyline points and use those as control-points. This will give you a very dense nurbs curve though.

another problem is that there are so many contour is overlapped, it may due to I make the metaball by many plane, so how can I over-kill then in grasshopper?

Hi David, Thanks so much but once I opened the file you uploaded, it said the clean tree plug-in is missing and its different in mine one. Where did I go wrong?

I tried to bake those line and then put into the definition, but it said
