Out of respect for your time I’ll keep this short. I’m a complete newbie to sketchup so I’ve recently been following tutorials to quickly improve my abilities. I’m no proffesional but someone who likes architecture and I’m thinking about studying as an architect (just turned 18). The problem is that I’m trying to create an object (a cylinder) with some intresting patterns (for practice) and went about doing it by making one half, copying it and then putting the copies together. However, I ended up with two main problems but can only show one as I can only upload one picture.
I don’t know how to remove this line and make the two parts one part. It’s the line that goes straight down through the middle. (these are two identical parts joined together) without removing the surface it connects to. I’ve tried smoothing (is that a word?) and welding (welding addon) :
