Revit Basics – Snaps

This is an excerpt from an article that I wrote for AUGIWorld.

If a new Revit user is an AutoCAD veteran, one piece of good news is that the object snaps are greatly similar from one program to the other; it is just a matter learning what snap options are available in Revit, where to find all of them, and when they are particularly useful.  Tutorial literature likely points out the snaps options dialog box, found on the Manage Tab, which provides much useful information.  What a newer user might not know, or might forget to use, are the two-key shortcuts for snaps and the snaps overrides.  To use a particular snap, type its two-key shortcut while drawing an element (the shortcuts are shown in parentheses in the aforementioned dialog box).  For a particularly useful application of the two-key snap shortcuts, try using the snap centers shortcut to rotate about the base point of an element with a very large radius.  To temporarily turn snaps on or off, right click while drawing an element to find the snaps override options.  These tools are well known for users of other programs, but are forgotten when working in Revit.

Snap Distances

I thought I would follow up from the last post with a small little tip.  When the Nudge command is used it looks to the values that are set in the Dimension Snap setting dialog.

As the description in this dialog box states: When the mouse is moved 2mm on the screen it will snap to the length dimensions that are closest to that zoom resolution, this is also true for the Nudge command.  A little known trick to this dialog box is to adjust it often.  I have heard many times that AutoCAD Architecture or other programs are nice because when inserting doors I can set a desired value and the doors just snap to that distance.

  Revit can do the same if this dialog box is used, Change the 6″ value to say 5″ (127mm) and then start placing doors, they will snap this distance from a desired corner.  I will also change that value to 8″ when  I am working with a brick or masonry wall, now when I model the wall is the correct length.  Of course verify that the temporary dimensions are also set approiately to what you need as well.
