Hilbert Curve Model Problems

Followed this tutorial:

Given that it was a completely different software,
I was feeling pretty good about my progress, until
I tried applying the Solidify modifier. Then it went
south.

Being as it begins with planes (of a sort) and their
precise alignment. I’m guessing that’s where things
went wrong.

I’ve tried the Precise Align addon as well as the
“Scale X 0” trick and I’ve tried deleting edges and
recreating the faces as well as removing doubles.

I’ve also tried flipping the normals to see if that
made a difference. So far, still screwed up.

So, what exactly is wrong and how best to fix it?

Rather than having to wade through a video show us what you see and what you were hoping to see so we know precisely what you are referring to

Your object has inconsistent face normals (some pointing inwards and some pointing outwards so some faces will be pushed in and others pushed out by the modifier). Select all faces and recalculate normals (Ctrl+N)

The Problem:


And, as you can see, fixed (used Shrinkwrap modifier w/UV Sphere):


Thank you for your help. And I’ll try to remember to
attach pics as well next time.
