Keeping Elements from Moving
In many cases, you’ll want to make sure some elements don’t move, because the consequences could be bad. Imported drawings, grids, levels, and exterior walls are some of the most obvious cases. Revit provides a couple ways to deal with this.
Pinning Elements
You can restrict an elements’ ability to move by pinning it down with the Pin tool. This tool is located in the upper-right corner of the toolbar. Select the element you want to pin down, and click the Pin tool. If you try to move the element, nothing happens—you don’t even get a ghost preview of a potential move. Use this tool to lock down critical elements that need to remain fixed for long periods of time. This is a great feature for imported CAD files, because it’s very easy to accidentally select an import and drag it or move it. This kind of accident can lead to coordination problems, even in a BIM envi- ronment. Use pins to lock down gridlines as well, because you certainly don’t want those to move accidentally. To unpin an element, select it and look for the pin icon. Clicking the pin removes it and frees the element
Constraints
Constraints aren’t as rigid as the Pin tool, but they do allow you to create dimensional rules in the model so that elements remain fixed relative to one another. You can create a constraint using dimensions and alignments and then click the Lock icon. A simple example is keeping a door a fixed distance from a side wall, so that if the wall moves, the door also moves. At the same time, if you try to move the door, you can’t. Look at Figure 3.22: The door has been locked to be 5 3 / 8 . from the wall face. If the wall moves, the door moves as well; but if you try to drag the door to a new location, you can’t. Another example is to lock the head height of a series of windows relative to a level. This pre- vents users from accidentally dragging windows into undesired locations while guaranteeing that if the level moves, the windows also move.
