I'm trying to create a sloping wall as a roof curb that attaches to a sloping roof. I can create the slope by editing the profile but, alas, they cannot join together cleanly with other walls. Creating a mass is also fruitless, because, lets be honest, this tool just doesn't cut it compared to more sophisticated modeling software like rhino. I'm just wondering when this is going to be resolved? It seems like we run into this problem far too often and it makes revit look like it is falling farther and farther behind in the design category (not that design should be done in it). Does anyone have a method to work with this without a) modeling a mass, b) editing the profile or c) modeiling another program?

I don't know why you would compare Revit to Rhino to begin with... it's apples and oranges. No pun intended. I have used refence planes to achieve your desire affect. Slope your roof, draw parapet, draw reference planes. then attach base to roof and top to reference plane

I formerly start 3dmodelling with rhino. There is no point of comparation. Check this link to do complex forms. The answer to your question is just above, you just have to think with the tools revit has the "how to".

Thank you for your responses. The condition I'm working with, however, is slighlty more complicated and will require more flexible modeling. I do make the comparison to rhino because of the ability to model masses and the fact that these can be read and converted into revit geometry (the addition of importing .sat files). Though they are different animals, they ultimately can combine their geometry in meaningful ways and thus warrent comparison. My concern is that the increased complexity necessary to acheive not so complicated tasks in revit is dissillusioning when seen in the light of revit's incredible potential towards realizing the ambitions of creating true BIM. I guess I wish you had more flexibility to design within the software to maintain more consistancy, but I suppose no one program shall ever hold the title of a complete design and documentation package and perhaps its simply okay for it to be that way. It just continues to be a point of friction and frustration. Thanks again for all your help.

So I have been trying to work through some of the suggestions that you all have offered and attached are some of the issues that I'm having: -Attaching the bottom of the wall to my sloping roof has a problem that I'm not sure what to do about, plus my name reference plane for the top does not show as an option in my properties dialogue. -If I edit the profile I get the desired slope, with warnings, but I can't join to adjacent walls. -The best luck that I have had has been with the in-place families created as a wall, but alas, I have no options to add to the structure or to create a coping profile. I would have the same functionality with imported rhino geometry. Any other suggestions? I'm really trying to not resort to doing my modeling in rhino or some other program just to do a roof parapet. Thanks.

if you have a very specific form, and it doesnt repeat too much you can use a model in place (place component/model in place) There you assign a category, probably roofs or sumthin, then model your specific needs. You can use simple extrusion.

That's what I did for the rest of the parapet. It works okay, it's just limited by the amount of reference planes you have to use in order for all the slopes to cleanup with eachother. I was hoping to have a coping profile attache to them, but I can't do this with inplace familes? Or I guess I would have to use sweeps within the family?

You could use a profile sweep along the edge of your in-place families. I didn't really follow this post from the beginning but I don't understand why you just didn't use walls, attach the base to the sloping roof and edit the profile for the top. No need for tons of ref. planes

I can't attach to roof. See previous with attached images.

I looked at your previous posts but I don't understand. You can and I do attach the bottoms of walls to roofs. I just did it yesterday where I had a wall that had to sit on a metal roof deck - modeled as a roof.

I don't understand either. It has a problem attaching to my roof, that's what I was trying to show in those images. As far as I can tell, all of the objects and constraints are modeled and set up properly; roof modeled as a roof, wall drawn on view associated with a level corressponding to the top of the roof, etc. It has a problem with the slope or something (it does slope in two directions in some instances). I want to keep it a wall so I can easily attached my coping profile without excerbating the problem with in-place family sweeps ontop of extruded masses and such.

If your roof is warped (sub-points edited), then that may be a problem. I would have to check that out. But if the deck is flat and slopes in two directions, that should not be a problem. In order to attach the bottom of the wall to the roof, the roof has to be under the wall and the wall may have to physically start above the roof.

I'll try a few more things and see if that is the case.

It turns out I can't attach any of my curbs to the roof let alone the ones I want to slope. I'm attaching a copy of my file if anyone wants to see whats wrong. It's 2011.
