Help making circles

[Kimberly]

I'm trying to create a circular station, so it can spin to produce gravity through centrifugal force. Sounds simple, right? Well, the problem is, this happens:

It seems my station wants to be a Mobius strip instead of a circle! I don't get what I'm doing wrong, can anyone spot the flaw? Here's my method: I take a single module, and slap Clampotrons on both ends. I angle each docking port two notches towards the top of the module (which I think is 10 degrees). I use Subassembly Manager to copy and paste this module, attaching docking port to docking port each time, with all of the modules oriented the same way. Why does that not make a circle?

Have you tried Alt+Clicking for duplication instead of Sub assembly? Maybe somehow it's just off by a couple degree's, reloading a save file from sub, no clue really though.

Try to make something like [core part, doesn't matter what it is] // docking port facing > , rotated 10* // docking port facing < , connected to the previous port(as in node-fixed, not surface attached) // the main module, node-fixed. Alt+click on the first docking port, attach it to the end of main module(this time surface attached, not node) and repeat, without rotating anything. This works well for bent structures made of girders, maybe it will work as well here.

By the way, you won't have any way to actually "glue" the ends together like this in the VAB, the last port will be not connected, no matter what you try to do. Personally, I'd put a single, round central part and add hammer-shaped modules(girder/girder/round module surface-attached to the end of the girder) to it in some high symmetry. It will look quite similar to what you probably have in mind, and will actually work, if reinforced a bit with struts between modules next to each other(use symmetry as well, this way you won't need to manually put every single strut in its place).

When i made the gravity module for my station i had a core with beams and then the circle stuck on the beams use a core

When you attach parts at odd angles the game seems, for some reason, to pick a new reference frame. In other words, changing one orientation sometimes results in additional orientations changing. To see an example of this take a wing part, attach it to a fuselage like a normal wing. Then shift-rotate it a few times to give it a high angle of attack, say, and then try to shift-rotate it so the wing is swept back, and you will notice that it behaves very strangely. This is what is probably going on here.

What I suggest you do is this: start your build in the horizontal plane. Build a quarter circle. The alt-click to copy it and attach it with the correct orientation it to get a half circle. Repeat the process with the half-circle to complete your ring.

Press Shift + (Direction) to move your parts by small degree. Hope this help.
