Revit Guide Grids
I have had this post in my queue for a while now. Often when composing sheets in Revit, we have similar views which we would like to appear in consistent locations from one sheet to the next. The most common example is floor plans. If you have each floor plan on its own sheet, you probably want those plans to align in the same general location with respect to their titleblocks. Revit has a tool for this called the Guide Grid. It is a slightly odd little tool that allows you to line up model elements in the same location across multiple sheets. It does this by allowing you to move the viewport on a sheet by snapping to the datum elements in your model (levels, column grids and reference planes) and then snapping them to the intersections on the Guide Grid. With plan views, the most likely element for this task is the Column Grids. However, if your building does not use Grids, you can draw some Reference Planes instead.
Using Guide Grids to align views
When I first started using the Guide Grid tool, I noticed that the default size was pretty dense, so I would typically change the size of the grid to the largest size I could get away with in order to reduce the visual clutter of the grid. This works, but recently it dawned on me that there is a better way. When you select a Guide Grid, it has grips on the edges. You can use these grips to resize the grid. So, if you reduce the size of the grid to make it very small, you can then move the entire grid anywhere you like. This location will be maintained across your various sheets (since this is the very purpose of the Guide Grid). So if you are using the Guide Grid to line up plans, this is a much nicer way to do it. Here is a quick video to explain.
