It's a simple need & I can't figure it out... I want to add a wall, at a diagonal, using rectangular coordinates. The dynamic prompt only allows polar input. I know there has to be an easy answer. I'm using Revit Architecture 2010. I'd love some help, feel free to add a little ridicule--I know I deserve it  Julie

I am assuming by diagonal you are not meaning you want a wall that goes to the North East, North West, etc but rather a wall that is diagonal where the base is not directly under the top of the wall...? If this is what you are wanting you will need to make a mass that has the slope and shape that you want for this wall and then use the wall by face tool to place a wall using the diagonal face of the mass. I do not know of any other way to offset (in plan) the base from the top of a wall.

No, that's why this question is so humiliating for me. I mean a diagonal wall in plan. I'm a beginner, but I've done the online tutorial and I've worked my way through Aubin's "Mastering Revit". Now I'm trying to draw a simple bay window in plan & I can't do it. In Autocad, I would have started my line, then entered @18,-18 In Revit, I use dynamic input. When I move the cursor to a diagonal to place a wall, Revit automatically switches to Polar input. I want to be able to place the wall endpoint at exactly 18" to the positive x direction & exactly 18" to the negative y. It's so simple. Isn't it?

How about placing the wall and rotating it 45 degrees?

(I tried to reply to this message once, so if this is a duplicate post, sorry about that.) Thanks for the suggestion. The problem with using polar coordinates is that, rather than draw the wall in the way it will be dimensioned (cartesian), I have to estimate the length of the line first -- so: [sqrt of (18" sq x 18" sq)]. The same would be true if I draw the line first then rotate it. Seems like there has got to be a simple way to toggle off of polar input and into cartesian, even temporarily. I ended up drawing 2 model lines at 90 degrees to each other, then snapping to their endpoints at a diagonal. Again, I just have the feeling that I'm missing something. A program as advanced as Revit can't be missing a setting option as simple as this. At least I've got my work-around & I'm on my way. I appreciate the tips. Julie

Ok, that makes more sense. You should be able to just draw the wall picking one point then choosing an other point...when you are about to select the second point you should have at least two temporary dimensions, one being the lenght and the other being the angle...you can try and get it to go to 18deg by hand, or what I would probably do is to place it at any deg other than 90 or 180 and then click on the wall...a angular dimension should show up...click on the temp dimension and change the angle. If the temp angular dimension does not show just put in an angular dimension by hand then click on the wall and change it that way. Hope that makes sense...if not I can post some pictures.

I think I just posted at the same time as you were. As you can see in my last post, I  eally* don't want to use angular dimensions in this instance - the biggest trouble, as I explained, is accurately determining the true length of the line. I want to input the wall using only "x & y", not "length & degree". Is there no way?

I got some stray smiley face in that last post. Re-Type: I think I just posted at the same time as you were.

draft 2 reference lines: an X line and a Y line then connect the endpoints with your wall.

Julie you definitely sound like you have an autocad background. As you get more experience with Revit and break your CAD habits you'll forget all about x,y

Julie - I suggest in the future, you don't use model lines.... you might forget they are there. Annotative lines would be better

reference planes/lines would be my go-to
