How do I get my curve to stay evenly apart? (Using Archimedes)

@fourpapa1 explains this perfectly.

The railing segments on the left side are ungrouped, as can be seen by the two light blue selection boxes. The railing segments on the right are grouped, as can be seen by the single bright blue selection box.
As is indicated, the ungrouped segments do not maintain the same distance between both sides throughout, but the individual segments do maintain proper connections. The grouped segments on the other hand, do maintain the same distance throughout, but the segments of the inside arc are not aligned. This once more goes back to what is demonstrated in example 2c earlier in the guide, where the inside segments are required to be shorter. This is an issue that will occur a lot when using Archimedes, but is easy if not tedious to correct using ResizeAllign.
