This question is already on here from 2006, but it was never answered satisfactorily.  I am wondering if this ability has ever been added (now using Arch 2014)?I run into this from time to time, but this is my most typical situation:  the dimension between a stair tread, and the bottom of the stair stringer over it.  See attached image.  This is a building code required dimension, so it seems like it should be possible to generate without faking it out.To currently make this happen, I have to make two little nubs of a line at each end of the dimension string to "fake" the dimension.  The interesting thing is, I can use the Measure Tool to display a temporary (light blue) dimension in the exact same place, without the fakey lines.  Then it leaves me a dashed line, further confirming that Revit knows what the distance is right there.  But then the next time you click anything it goes away.  Is there any way to make this temporary dimension a permanent one without faking the dimension?

Thanks!

Use an aligned dimension and have your pick set to individual references. Then use this tip: You can cycle through the different reference points by pressing Tab. A blue dot reference displays at intersections of geometry. A gray square reference displays at any intersection of internal wall layers.

That's right from the help file under "Aligned Dimensions": http://help.autodesk.com/view/RVT/2014/ENU/?guid=GUID-E0FB313E-CE57-4741-9EF5-6747BBA3BDDB

HKicsak,  The aligned dimension will not give the poster what he wants.  Try it out for yourself then come back with how your answer works.

I did try it- but again just now with stairs. The objects I used the first time apparantly weren't "non-parallel enough".

What we do in this situation is either:

1. draw a symbolic line (Centerline) from the tip of the nosing to the underside of the obstruction.  Then dimension from each end of the centerlines
2. place two "centerpoints" and dimension from those instead.

I noted your using the midpoint of the tread, we have to use the tip of nosing.  but the principal is the same.

It's our only workaround.
