So can anyone help me understand some graphic glitches?

[Batchman]

Could just be I don't know what I am doing, but I spent a fair amount of time recreating this micro-ride that somebody else made, and I ran into two major problems. One was that at certain places, the walls would not go in on one side, so I had to move them to the other, causing slight lines to appear because one tile was microscopically farther out than another, but it would not allow it to be any other way. This was a mildly annoying issue, but not anything major enough to lose sleep over.

On the other hand, you see that one large open space that doesn't have a door? I spent well over a half hour trying to place a door there, and it just wouldn't go, no matter what I did. It would keep trying to place the tile a space and a half above where it belonged, whether I tried to go in front or behind. The only way I could get a door in place was to remove the track, at which point the door would place. But as soon as I replaced the track, the door would vanish.

Any way to deal with this, or is it an actual full-blown, no excuses glitch?

The walls you place are within the lines on the tile, if you place it in the other tile, the wall will seem to stick out

There is a cheat you can use to place obejct wherever you want

The cutaway view might also help you see inside structures

Oh? How can you access that? Would be nice to be able to build perfectly.

Activate the cheat-tab in options,then hold the yellow shovel to see the options, think its called something with 'Disable clearance checks'

[Broxzier]

It seems that some track pieces don't allow wall-doors to be build on top of them, even though when build there with clearance checks disabled they do work fine. This is probably the same in Vanilla RCT2, and should be changed.
