    Spot slope annotation for ramps

    For some reason that we don't know yet , the Spot Slope annotation tool does not work on ramps in plan views. It works on elevation, sections, and 3d views, though; however, it's on the plans where I need it most. Until this is fixed in the future, here's a solution that you might find useful:

    From a 3d view, create a model line with thin line style, aligned and locked to one of the slanted edges of the ramp. (That line is represented in heavy red in the image, for clarity). Then go to the plan view, and try again the Spot Slope annotation tool on the ramp, but this time use the tab key to find the model line. Now you have the slope of the ramp.

    If the slope of the ramp changes, the annotation will update, since the line is locked to the slope of the ramp. The ramp can be edited, shortened, lengthened, and moved, without affecting the slope annotation at all. Only issue I found is that when the ramp is rotated, the constraint is lost, but then it is very easy to align and lock the line to the ramp again, and the Slope annotation goes back in place again, updated.

    There is another way that might be even easier than this. You can darw an object in plan that WILL take a spot slope (i.e. a floor with a slope arrow), then use the spot slope tool on that object. Now select the spot slope annotation you just placed on the flooor object and move it to the ramp object. The slope will be reported correctly and change in response to changes made to the ramp object.

    P.S. This trick works for placing a spot elevation annotation on a ramp object in plan as well.

    In added and articel to the wikihelp on this process as well.

    Amazing, Jeff. The big question here is why does this task have to be a hidden workaround and not a simple feature?
    A ramp cannot take a spot slope annotation in a simple way, but it can, in an 'indirect' way...

    Yep--I agree with Alf. Sounds like a bug in the program.

    I don't know the "technical" reasons why it works the way I discovered, it just does. I just happened across this trick last week when a feedback e-mail was sent about adding the ability to place a spot elevation on a ramp in plan. I thought it had something to do with the way 3d geometry was being generated for the ramp object in plan. Turns out that is not the issue. I just stumbled across this "solution" while messing around with things.

    @Cliff - It is an issue that has been logged for some time now.

    Interesting, Jeff. Well, then, the Factory should fix it. I met with a group of architects some weeks ago, from one of the largest firms here in Miami, and they were very disappointed about Revit ramps. One of their reasons was the fact that they could not apply the spot slope annotation to their ramps in their floor plans; so they were using just text and arrows, with the risk of showing wrong information later if the slope of the ramp changes. Well, it's good to know now that there are at least 2 solutions.

    4 years later and it still hasn't been resolved...

    Yes. Just for the sake of it, every year, with every new release, I go ahead and check if they have fixed this. If they didn't, I do like the prisoners in the movies: I draw another vertical line on the wall to count another year, haha...

    But, don't worry. As Jeff says above "It is an issue that has been logged for some time now.".
