joining two boxes

[bubba]

I can understand you might think this a strange question (because there is a simpler way - maybe) but if I were to create two separate boxes, then place one on top of the other and join the corner CPs, are there still two splines or now just one?

hmmm...

 

I'm going to guess there are two splines occupying the same space. Probably not good. I'd delete one before dong the join.

Robcat is referring to the horizontal splines that define the bottom of the top box and the top of the bottom box. Yes, there are two stacked splines after joining, and as I am a much clumsier animator than he is, I have made this mistake - it causes all sorts of problems. Before joining, select one spline or the other, and delete.

 

That leaves the issue of how A:M will interpret the vertical splines when they join. Occasionally, depending on how the box was constructed, A:M will decide to join them oddly. Then you have to delete both horizontal splines, join the vertical ones, and add the horizontal ones back in. Just takes a minute.

Thanks. I know that extruding is the preferred method.
