sandbox is sucj a fantastic tool... i a doing a major complicated counctry side countours and its pure magic. One feature which would be handy is when its processing to make the contour, a STOP button to cancel the process if needed...

Great, ingenius!!!
love the way u have named ur images as Mess 1,2 and 3...lol.. yes agreed, it is a very messy file.

The quarter cone in the original sketchup file is wat I created (has 3 faults, which some i am not able to correct coz if i do, it deletes the curved faces), then copies and flipped them...after which i smoothened them, which is a terrible idea as it multiplied a lot of errors... Looks like this method is not the way you did.

Could you briefly explain how you created this simplified version of the shape?

Many many many thanks for the replying to the post.

hi,
I am trying to calculate the volume of a complex shape. its basically a cone shape with an elliptical base (made of atleast 5 ellipses) and a smoothened tip(again a bit complex with a curve and elongation)...somehoe i managed to do the shape, but i am having trouble finding the volume for it. i have the volume calculator plugin but it keeps saying that the shape needs two faces and blah blah... basically too complex to read. how do i calculate the volume or re-do this shape(needs to be precise tho as it has engineering calculations behind every mm. . . kindly advise!!! desperately need help!!!

Attached skp file below. Also tried exporting the shape to autocad and trying to find the volume, but no luck there too!
