tfurrows, re: measuring for outlets, light fixtures, etc. To begin with, here are some general principles: think of everything as a grid. Rely on a square to find the positions in the grid. Here's a little ASCII art depicting a traditional L-shaped square to convey the general idea of what follows. But it really helps to have a full size (48") drywall T-square for doing this. ------------------- | | | | | | | | | | | | | | <-- square | | | | | | | | ----------- | | -- | | | | <-- fixture | | -- | | | | | | <-- neighbouring panel ------------------- Install panels until you get close to the proposed cut-out. Let's say that you're installing the panels vertically and you've installed panels from left to right along a wall. Put one side of your square against the right edge of the neighbouring panel and line the other up with the bottom of the fixture that you need to cut a hole for. Then: 1. Using a pencil, mark the point on the neighbouring panel parallel to the bottom of the fixture. 2. Using the measurements on the square, write down the distance from the neighbouring panel to the close and far edges of the fixture. 3. Move the square up to the top of the fixture. Mark the point on the neighbouring panel parallel to the top of the fixture. 4. Measure the distance from the bottom of the neighbouring panel to your two marks. Now, when you measure for the hole on the new panel, the distances you measured up the neighbouring panel are the measurements (from the bottom of your panel) for the bottom and top of your hole. The distances that you measured over from the neighbouring panel in step two are measurements from the left side of the panel to the the sides of your hole. If you just draw out the lines on the new panel (using the square), they will intersect at all the corners. If your hole is round, find an appropriately sized container lid and center it inside the lines. Then trace around it. If the hole is hexagonal, just wing it by drawing in the cuts across the corners (or grab another electrical box and trace around it). You can also make all of the measurements out of a corner, or from the ceiling downwards, etc.
