I guess you all are familiar with spiraling stairs needing more than one turn to get to the next level. The trick is to make more than one stair. So what I did is put one in place. get the height of the last tread start a new one align them. etc etc. troublesome, troublesome.
Just yesterday I found this out.
You start your one stair in sketch mode not just 360 degrees. stay in sketch mode and draw the second run on top of the first one, just like one would with a straight stairs with more than one run. Difference is the sketches can overlap. then just finish the sketch and voila, one undivided more than 360degrees spiraling staircase. easy.
I guess you all knew, but it just made me happy.
I think I will now go and try if I can overlap sketches of straight runs, who knows?
