dimensions

Is it impossible to place a dimension between two walls which are not penpendicular to the screen?
We got an error message.
See figures as attachments.

No, what is not possible is a dimension between 2 non parallel walls, what you have is one of your 2 walls is slightly off parallel from the other. If you put 2 angle dimensions from your perpendicular wall to each of the 2 you are trying to dimension you will find they are not 90 deg exactly. you may need to turn up the decimal places on your dims to see it if they are set to round right now.

Nothing is impossible....
You can dimension from the one wall, go to an endpoint or ref point on the opposite wall and press tab a few times. You will see a tiny dot that appears. Voila dimension.
We had a similar problem once, after tracing a dwg of a hospital.
We landed up redrawing the whole lot....after trying to reset the angular dimension units to have more than 12 decimal spaces.
Are these walls meant to be parrallel?

If you know what the dimension is meant to be, it can work best to offset a line or reference plane from the correctly located/angled wall and then align the incorrectly located wall to this line/ref plane. (then delete the line/ref plane.)

Indeed, the two walls are not parallel.
What I can make, is a dimension line between the two red points ...

We have run into the same problem. Walls not parallel to the view are not dimension-able. Also we cannot get many of them to be room bounding and we get erroneous areas from rooms that we know are the same size. It appears the area routine is affected by slight changes in the angle of the wall and the number is off. See attached image for an example of parallel walls that will not dimension. The tool will not even select the first one.

Surely the walls should be parallel (even though they never get build that wayimages/icons/icon10.gif )
Chris, see attached fig A….
Dimension from “point 1” go towards “point 2” press tab (don’t hold it down, just press once or twice) near the corner.
You will definitely get a dimension then. (Did you trace this from Cad?)
“Point A” Looks like the walls are not joining at all. Try a join geometry or trim to fix that (This might be where your room areas are going pear shaped)
Also make sure that all walls are room bounding (attached)

(ie not vertical) If this is the case then a dimension in plan is pretty much meaningless anyway. You should be able to dimension them in a section that is perpendicular to the walls.

Mike,

See Elrond's post below. The tab does not do anything since the walls are not parallel to my view. They are tilted. It looked to me that was what mark was trying to do as well. We have no problem dimensioning to an endpoint of a wall that is not parallel. Try dimension to a tilted wall even if it is parallel. Mine are parallel in plan and section but where would Revit determine the dimension point? I suspect that is the problem with the room tags as well.

Would a reference plane help you in this situation. See the attached image. I applied a reference plane where I wanted the dimension to go to, and then dimensioned from the wall to the reference plane.

Hope this helps.
