Hi steve, there is something wrong with those ones - if you zoom in really close to their tip you can see that it's kind of messy there:





That thing that looks like a tiny squished flat edge actually appears to be a slivery thin tiny additional surface, and a degenerate face like that will interfere with calculation of the outward facing surface normals. So probably that little tiny face will need to be removed and the points of the large one squished down to a single point to make that into a proper solid without any degenerate things in it.

Thanks michael, I just merged off the ends, left me with a flat end, thats less than 0.01 mm :) cleaned up a few other places has well :)

Hi Steve
I am interested how you made the leaf shape pieces that were the problem

they appear revolved but I have problems making them

cheers

Hi shayne, maybe doing a revolve and then using Flow could be a good method, check out here for an example:

Thanks Michael

Hi Shayne

I think the revolve and flow, would be an easier method, I think I used sweep with 2 rails and had a few problems ;) ( when I get a chance I'll pull up the old files and have a look at what method I used :) )

Cheers, steve
