I am a total noob trying to do a tutorial - to make a neon sign. Here's a link to the tutorial: https://www.youtube.com/watch?v=eQjQfmjDXXA
Basically, you convert text to "curve from mesh/text," then go to "curve > shape > fill (none)" and then "geometry > bevel." So at this point, you have grey tubes. They are doubles, so to get single tubes, you have to select points in each letter and "x > delete > segments." Then delete the parts you don't want. Now you have single tube letters.
Here's my problem: The next step is to select vertices on the letters to extrude back - to get a 3D neon geometry. I am getting weird artifacts on my "U" letters (flickering). When I go to extrude, they extrude weird droopy extrusions (see attached). Other letters extrude straight and correct. I have tried deleting the "tops" of the "U" and reconstructing by extruding up from the lower part of the "U" and I get the same result each time. Any ideas what is causing this baggy distorted geometry?
Thank you for your help and patience with a beginner trying to learn!
