Long hand Iterative Alignment (without using Iterative alignment command).

Hi all,

After a discussion in another thread I thought I'd post an example of an iterative alignment done long hand (without using Iterative alignment command)

There are two reasons for this.

1) When using iterative alignment command it's necessary for the vectors of your features for each group (Level, Rotate etc) to be roughly the same. For example you cannot have three points for a level where two are approx 0,0,1 and the third is 0,0,-1.

2) I think this is a great way of understanding what's going on when you do an iterative alignment - before I saw this method it was a bit of a black box to me, this made it all clear.

It's ages since I've done it so, it might not be the most elegant method, but it gives you the general idea.

This was done on the hexblock if anyone wants to copy it and have a play.
