Hey all. First problem: I'm attempting to build a spiral staircase. I searched the internet and all I found was a valve site that showed a method with the arch brush. So I followed the steps and poof!... I got my stairs. I was thinking of ways to enclose the stairs, and this was my idea. I took the arch brush, made the size 8 units bigger on the X and Y planes, and, using the exact same parameters (save the height add), I made an arch to surround the stairs. Here's a picture of the staircase, with the stairs selected: It almost works perfectly, but the enclosure doesn't quite match the stairs. The next two pictures are of the staircase with the enclosure selected, and a 2D top view of how the enclosure doesn't quite line up: I'm perfectly prepared to scrap the whole thing. I'm looking for suggestions, advice, whatever! Second problem: Above the stairs I'm trying to build a floor. My idea would probably work (although it was very tediously done) if the rest of the staircase had worked. For this, I'm just wondering if anyone has any better ideas, or whatever And the picture: Thanks in advance for any help!!
