When trying to use a brace, it changes the camera angle before i can place the 2nd end of it, making it impossible to see the spot to place it. i'm not sure if i can finish much more of the game without using braces. some attention to this would be appre

That is a game design feature done to only allow using braces between joints on the same plane. The correct way to use a brace is to create a "plane structure" o side, brace it, and afeter the braceing, add more parts. But if you have a full structure, when the camera changes it's angle, it's easy that some component of other layer/plane gets in the middle of the view and doesn't allow you to click on the joint needed.

You may remove some parts to improve visibility, add braces and after the bracing, add again the parts you removed before. If the problem it's other thing, you have to think that a brace can only join two joints in the same plane, so when you click on the first joint, the camera changes it's angle to show you the "plane" that can receive the second click.
