making a symmetric model

[gbon]

<DIV>I'm building a part with several pro/surface and Isdx functions.</DIV>
<DIV>It's somethink like a bike, so it's have a symmetry plane.</DIV>
<DIV>So, I'm modeling the half of the model and making symmetry function near tothe end of the function tree (some details aren't symmetrics).</DIV>
<DIV></DIV>
<DIV>Near the endthe whole model is an open quilt so I've tryied 2 methods :</DIV>
<DIV></DIV>
<DIV>1/</DIV>
<DIV>- I make a planar surface in the middle plane</DIV>
<DIV>- I merge this one with my surface (so I got a closed volume)</DIV>
<DIV>- I solidify this volume</DIV>
<DIV>- I make a symmetry function on this closed and solid volume</DIV>
<DIV></DIV>
<DIV>2/</DIV>
<DIV>- I make a symmetric quilt (with wymmetry function)</DIV>
<DIV>- I merge the two quilts</DIV>
<DIV>- I solidify this volume</DIV>
<DIV></DIV>
<DIV>So, in both cases, one of the functions spend a lot of time (seems to depending on tangency condition in the symmetry plane).</DIV>
<DIV>(In case 1 : symmetry - in case 2 : merge).</DIV>
<DIV>a lot of time : I mean that this particular function spent more time for regen than all the other ones, more than one minute.</DIV>
<DIV></DIV>
<DIV>So I'm wondering what would be the best approach in this sort of problem.</DIV>
<DIV>I can't change precision because other functions.</DIV>
<DIV>So what is the best method ?</DIV>
<DIV>How handle this sort of symmetry/precision problem ?</DIV>
<DIV></DIV>
<DIV>Thanks,</DIV>
