Re: Revit dimensions suck

I've attached a PDF detail at 1 1/2" = 1'-0" that will hopefully help illustrate my issues. Pleae forgive the lack of detail and graphics. This is still in progress, and I'm still learning to detail in Revit. 


This shows that Revit will not dimension to the intersection of rafter and stud wall- which is the top of wall plate. That point is 9'-0" above the level dimensioned to. The roof is offset at 9'-0" from the level and is located correctly. 


This is where I have to unjoin the wall, place the dimension to the rafter-stud wall intersection, and then rejoin to the wall to the other elements. 


Thanks very much for taking the time to have a look at this. mpp

If you zoom into that intersection, hover over that point, and hit tab, does the selection point change?

No the selection point does not change. If I zoom in an d click on that point, Revit will exit the command.

You're right. I'm not either able to dimension to that intersection after attaching the wall to the roof (rvt 2014).


I have a workaround though; detach the wall, draw a ref.plane through the intersection point, strech the top of the wall to the ref.plane level, remove ref.plane, dimension to top of wall, attach wall to roof. Well, I don't actually know to what the dim.line is connected to.

I've experience something similar, in that when two overlapping walls that run parallel to one another are joined, the faces that lie within the overlapping area can't be dimensioned to or even aligned to.  It's as if they cease to exist, and I imagine something similar is happening here, since you mention that you can't dimension to the point you want until you unjoin the two objects.  I'm not sure why Revit stops recognizing faces/intersections for joined objects, but I can confirm the issue.


I'd recommend submitting it to product support.  Perhaps it will be addressed in a release update or a future version.  For the time being, you'll have to continue unjoining, then dimensioning, then rejoining.

Thanks for the response guys. It's releiving to know it's not jsut me and something I did in my building model, and it's also frsutrating to have to do yet ANOTHER work aorund in Revit. 


How do I submit this to product support? Does Autodesk even bother to respond to issues like this? 


Cheers! mpp

One work around that I use when I can't dimension to a particular point is to add a reference plane and dimension to that. You may have to adjust the length of the dimension leader/line.  The reference planes don't print.

Furthermore, I've discovered that when trying to detail a wall section, not only will Revit not dimension to the intersection of wall and rafter, it will not snap to that point at all. I can't draw a line from that intersection, or place a detail componenet snapped to that point. 


Revit seems to ingore that point all together. 


The work arounds are to either: 1) set two reference planes - one for the top of plate from top of plywood, and the other for the inside face of stud; or 2) unjoin the wall, drawn the lines/place components, and then re-join the wall to all other elements.

roof cut.pngI don't want to tell you how you should do your detail, but looking at the PDF you attached:  wouldn't the top of the wall stop at a double top plate, which would be flat (not sloped as the top of the wall in the PDF is) and then the rafter would be bird-mouth cut to sit on top of the top plate?  If thats the case, then the dimension you are trying to draw would be easy, as it would dimension to the flat part of the top of the wall. I've never seen a framing condition with the sloped topped wall you are showing.

Scott, that's what I thought looking at this specific example.


There is, however, still a problem when trying to dimension to an angle as shown in the eg. here. I've come across it a few times and have had to resort to ref planes to create the intersection to which i can place a dimension. It's a work around, but frustrating as it feels as though the snaps should be able to pick up intersections within wall/roof assemblies.
