Excellent, thank you very much!

Everybody was so helpful here and put up with my newbishly dumb questions that I decided to come back and ask another newbishly dumb question!

I'm wondering if anybody can point me in the direction of a nice terrain modeling tutorial. I don't really want to model terrain from real life, but I do want to be able to create terrain from scratch.

Any help is greatly appreciated!
Thank you and Merry Christmas and Happy Hanukkah!

Ah, perfect! It was actually the "endpoints" that were causing the problem, but once I got rid of those I had to get rid of the extensions too.

Thank you very much.

Hello there! I'm sure this question has been asked numerous times but I don't know what these things are called to search for my answer.

When two lines intersect, the edge is sort of emphasized. I don't know what they're called so I just call them brackets.

These brackets overwhelm small details when zoomed out, and I'm trying to figure out how to get rid of them.

Since words have failed me, I have illustrated it.
