So... I am working on a site plan and puttin in curbs... I want them to follow the contous of the site - I know there is a way but i can't think of it... How do i do this.
Thanks -

Solved! Go to Solution.
The only way I know is this: create profiles, load them into project. Create model lines that follow the edge that you want to convert into a curb (because you can't use "pick lines" on the site), then use "pick path" > "pick 3d edges" and select the model lines that you created, finish the path, select profile, pick a profile from the list.
Oops, it seems that you posted in the wrong thread? Surface patterns?
Okay Maybe i am missing something or it is just too early to think Alfredo - but i am having trouble getting in the model line to follow the contours... Any thoughts?

As I said in my previous reply, "pick lines" does not work with contours, you have to create model lines on top of them, without the help of pick lines, unfortunately.
I made the roadway in plan first, then edited the sub elements to roughly follow the countours, then added a sweep blend with the curb profile. Unfortunately it's a PITA and sometimes wouldn't let me create the sweep, leaving gaps in the curb.
This is my first job where I tried to model the site, if anyone has a more humane way of doing this i'm all ears.
There is a limitation about using "pick lines" on the topography. To overcome this limitation, we could try this: export the topography, and import or link it back. Now we should be able to create a sweep using "pick 3d edges" on the contours imported from the topography (note: be aware that using pick lines on dwg files might create some issues or inaccuracies). If I remember correctly, that is the same technique that Marcello Sgambelluri has demonstrated in his classes on topography. If it is not, I am pretty sure he will come to this thread and help us.
All of us agree that Autodesk should come up with a specific tool to do this in a simple way. There are already some third party tools to make these curbs. I have seen them in conferences.
If it helps, here's a link to a video I did in April 2012, that could still be an alternative. The points in the video go around a curvy shape, which is flat, but since the points are adaptive, they could have different elevations as well. This is a family that is created with the generic model adaptive template, with a profile that was made with a flat generic model family :
Alfredo, Marcello,
Thank you both for your responses.
Alfredo:
I saw your video a while back, very informative, thanks. I started working with the adaptive families but have gotten away from them. I think it's time to go back and revisit.
Marcello, fantastic job! Unfortunately I haven't been able to attend AU in several years so I was not able to attend your class. This should lower my frustration level significantly. Perhaps Autodesk will incorporate some of your processes into Revit.
A couple of questions/issues.
1. When I import the drawing back in to Revit the spline will not allow me to pick the points on the DWG to set the nodes. I do not have much familiarity with massing as we don't have a great deal of need for it other than very simple shapes. So I know it's something I'm missing. I appears to be drawing the spline in on whatever plane is being used as a reference. It will allow me to pick the edges of the drawing but nothing else. I also tried it with the sample file you provided to see if it was something I had set wrong in my project but had the same result.
The beam method should work for now until I get the spline issue figured out.
2. What is your feeling on parking lots. I've used various methods. Typically I create a flat area, using either a floor or building pad and adjust the site but sometimes this takes a fair amount of manipulation as the parking lot slopes from one side of the building to the other. The issue isn't really the parking lot itself but the stripping that becomes an issue. I've even gone as far as subdividing the topo and for the stripping but this is EXTREMELY tedious and only used when I have no other choice.
3. Any ideas on the lousy text editor?
Update.
I created a mass and imported the DWG. I then created a second mass and was able toy use the first mass to pick the points for the spline. That may have been the process you used but I missed that. Works nicely after I figured that one out. The only problem I had was Revit kept telling me there was a serious error and wanting me to save a recovery file. That eventually went away. I'm not sure if it was a graphics issue.
One other question, when you used the splines to generate the fence along the side, did you copy those original splines for use later? It appears that when you create the form to use for the road it deletes the original splines. I'm assuming you made a copy but I wasn't sure if there was a setting that would keep the original defining edges.
Marcello,
I can't tell you how much I appreciate the information you provided. It's already proved to be invaluable. Using your techniques i was able to come up with parking striping that follows the contour.
Thanks again.
Marcello,
Thought this might interest you. Here's a macro for creating model lines from the topo edges.
