Hi guys,

I was hoping that perhaps someone had some tips/hints on combining which are parts based on equation driven curves?

Some backround information.  I am looking to create a ring structure which is based on a sinuosidal pattern:

I do need this ring to be fully defined based on specific geometries, hence the reason I am using equation curves.  Unfortunately, based on my experience, SW12 does not allow for the creation continuous curves (i.e. I cannot define my curves for an interval of [0 -> 2pi]).

As such, the best approach I could think of is to define the curves for half the inteval [0 -> pi], then to use either a Mirror or the Copy/Rotate/Translate/Combine features to generate the second half.

This worked reasonably well in the beginning (see the picture above).  Unfortunately, after exporting the geometry for analysis in another software package, the "combine" feature does not seem to hold (i.e. the post-processing software essentially sees two seperate parts, rather than one continuous ring).  Due to the functionality of this software, it is not possible to use two parts (the ring really needs to be one solid part).

So, what I am looking for is some more insight into the Combine feature in SW that insures a body and its copied part (which has been moved, translated, and contrainted into the correct position) are infact combined.  Any ideas?

The mirror feature does seem to have this function (i.e. select -> Merge Solids), but mirroring does not align the second half correctly (as it needs to be rotated about the x-axis 180deg).

Thanks!
