    Noob needs help with settings to force 1" increments and nothing less please!

    Hi, I am just learning Revit and am a residential draftsman. I am working on my first set of plans and have managed to learn all of the basics to get the job done, but one thing I have not been able to figure out is how to force my walls to 1" increments. When I draw them I specify 1" increments but when another wall joins the end or something they get thrown off into quarter or eighth inch increments instead of snapping to full 1" spaces. I have set the snap to no less than 1", is there something else I need to set... like how the walls choose where to connect or something? Please help!

    I'm slightly confused. Could you post a screenshot?

      Sounds like you've come from an AutoCAD environment, where you tend to use nominal dimensions.
      Generally, in Revit you are drawing things using real-world dimensions, not nominal.
      If something is displaying a 1/4" dimension, that's because it really is 1/4" away from something else.
      You're probably not going to get much love here if you say you want Revit to round things off, or report a nominal dimension. We tend to like things exact.

      I'm more curious about your comment that walls move when you snap something to the end of them. That doesn't sound right. Revit should not be "throwing things off" once they are drawing.
      My guess is that when you say you've "forced your walls to 1" increments" that what you've actually done is set your cursor to DISPLAY 1" snaps. When, say you're drawing a wall, the temporary dimension showing it's length will jump by a certain amount based on how far you're Zoomed In. That's under the Manage Tab, Snaps icon, "Length dimension snap increments" option. That will affect the length of lines, but not the starting point.

      My preference for placing (note I said "placing", not "drawing" - you're not just drawing lines!) walls is to not worry about the exact dimension when you start placing a wall. place the wall approximately where you want it and then use the blue Temporary Dimensions" to get an exact location.

      And don't sweat those 1/4".

      Oh, and welcome to both Revit and the Revit Forum!

        more questions and clarification

        Hi Dave, thanks for responding.... you are correct that I am coming from an AutoCAD environment, and I do get the difference between Revit as BIM and cad, but when drawing house plans I really need to get the dimensions to 1" increments to produce "clean" work (I am also a home builder and know how frustrating it would be to try to frame a house with quarter inch and eighth inch dimensions all over the place). And when I look at work other draftsmen - designers have done they are all able to produce work that is nicely rounded to feet and inches without any quarter inch or eighth inch dimensions anywhere. Any suggestions on how to more easily make this happen would be GREATLY appreciated!!!

        What I meant by walls snapping was that when I am laying out a footprint of a home and for example lay a back wall that is 25 feet long, when I move off of chain wall to connect the other end after working my way around or just by clicking to start a new wall that is connected to it, it will not necessarily keep its dimension... the new wall section will add a few inches, or something based on where it is connecting I suppose, but I try connecting at different points and none of them ever seem to hold on to the nice round dimension that I started with. The 25 foot wall all of a sudden is 25' 5 1/8" or some off the wall number because it did not connect the outside corner to the outside corner like I would want it to. So any help with how to make this happen cleanly would also be appreciated! Thanks!

        When you say don't sweat those 1/4".... do you produce construction drawings? And do the people you work for not mind those odd dimensions?

        Thanks!!

          1" increments.....adjust your Project Units under the Manage Panel...click Length...Change your rounding to 1"...

            BTW....I produce Construction Drawings and everything is dimensioned down to the MM....For a lot of inspectors...being off 3mm is a VERY big deal...

                I do a lot of custom homes as well. I also try to keep everything to the nearest inch if possible. But, I model it that way. Some dimensions won't be, can't be, to the nearest inch. Then I let it show what it is. Walls at angles other than 90* to each other come to mind.

                You'll need to get used to using your temp dims. Like Dave P suggested, draw the basic shape and don't worry too much about the exact placement. Then, select the wall and edit the temp dims to make it exact. I came from 14 years of ACAD, and I fought this when I went to Revit. It actually is way faster.

                Also, when modeling your exterior walls, try setting the location line to the exterior face (you'll find that setting in the options bar just under the ribbon when you start the command). That way, as you model your chain of walls, the exterior point is where the length is taken from. I think the issue you are having is that the location line is set to the center of the wall. Also, go counter clockwise around your building, otherwise, your exterior face will wind up on the interior of the building. It's an easy fix, just hit the flip arrows. But, may as well model it correctly the first time.

                  a 1/4" isn't a big deal in the field to layout or measure (I've done it as well.) A lot of your materials come in sizes that are 1/4" or 1/8" actual dimensions anyways - a 2x8 is 1-1/2" x 7-1/4", an 8" CMU is 7-5/8" x 15-5/8" + 3/8" mortar. If you really want clean dimensions you can do it but you will have to design that way and possibly change how you annotate your drawings.

                  When the wall dimensions change it is most likely related to your Location Line settings. If your LL is set to center of wall / core and you draw a chain of walls the exterior dimensions will change to accommodate the new thickness. Change your location line to Exterior Finish Face and it should go away.

                  edit - or what Dan said

                  this too. I just tried to do some work in CAD and I spent more time trying to lay out walls and remember how to do it than it took me to lay everything out in Revit correctly and add dimensions and all my doors.

                    What he said!
                    We've had jobs where we had to rip out a wall and move it over because we dimensioned to the gyp board layer and didn't account for the thickness of the ceranic tile. Some inspectors will whip out their tape measure and make you move a wall or a sink because it was 1/4" too close.
                    And, from personal experience, when I remodeled my bathroom, I had to return the shower door and buy a bi-fold door because the first one I bought was - you guessed it - 1/4" too close to the toilet and couldn't open. I wish THAT drawing had used an accurate dimension.

                    That still worries me that a wall is moving 5 inches, though. Are you saying the wall actually moves over 5"? Or it gets longer by 5"?
                    If it's getting longer, then you probably want to look at the Location Line as you're placing walls. That show up on the Options Bar once you're in the Place Wall tool. If it's set to Wall Centerline, what happens is you place a Wall , say 25'-0" long. Then when you place a wall perpendicular to that, the point you pick is the center of the second wall. So the first wall gets longer by half the width of the second wall.
                    You might be happier if you change that Location Line to Finish Face: Exterior. Then all of the points you pick are at the outside face of the wall, and the lengths won't change. But if you have a 4 7/8" partition, the inside face is still going to be 1/8" from a nice even number.

                    Good luck. You'll get there!
