Gidday All,

I am trying to animate a DNA Strand as it grows and spirals around. I have tired partial extrude and it works pretty well but DNA is an usual structure in that the true strand rotates in all xyz modes as it spirals around… so the partial extrude works well except the resulting extrude does not follow the correct orientation even though it follows the correct spiral. I can achieve the correct shape using loft shapes BUT I do not think you can animate a loft easily without physically moving the loft curves back onto them selves over time… rather tedious.

I also can build the correct shape using create animate sweep.... but that can’t be animated over time can it????

Any help most welcome. I remember seeing at some point years ago a mathematical way of duplicating a shape with the correct offsets in xyz translate and rotate that built the dna curve correctly.... cant find it now but that may help if I can figure out how to animate a loft

Thanks

Hi Peter,

This may be moved to the animation section or some such...just to say.

Have you tried the WSM Path Deform? Or material opacity animation? Or Slice?

See attached for animating a loft.
