Often we must number a whole bunch of Revit elements in sequence; rooms, areas, parking spaces, doors etc. A great way to automate this using Dynamo is by using a spline as an input to determine the sequence for these items. I show you two methods you can use in this video to automatically number rooms/parking spaces respectively; intersection and proximity to spline.

Turns out you might need to use a 'minimum item' node after you use boolean masks - the intersections don't always come back in order of parameter!

@IshiFrenchy 2 года назад

Hey ! I'm having trouble. Even after I use the minimum Item after one or both boolean masks I didn't get the right order...

@AussieBIMGuru 2 года назад

@@IshiFrenchy try running it @L2 so you work across sublists/objects. This is only for a workflow where you intersect a surface or solid object.

@mercurator6131 2 года назад

Hi, thanks for another really helpful video! One question though: why go through the (seeming) trouble of getting all elements in the active view, filtering them for Rooms (via object to string) with a boolean mask, if you can also Get All elements of Category and choose Rooms in the dropdown? Is that less reliable maybe?

@AussieBIMGuru 2 года назад

You could obtain elements in a variety of ways, usually I use the 'all elements of category in view' node these days, but I worked with a filtering down process in this tutorial to teach people how to isolate elements by a property as most people aren't familiar with this fundamental concept. I avoid dropdowns unless they are needed for Dynamo player because they change between Dynamo builds when more or less categories are available to choose from, usually I use category by name where it suits.

@PauloFerreiradyn 4 года назад

Great video, as always. I really like the second method, cause we don't need to get all the elements geometry so, in theory, it runs faster, right?

@AussieBIMGuru 4 года назад

It would be about the same speed I think, as we're using i intersect or closest point.

@mawjaldarraji5590 3 года назад

Hi, Thanks for sharing, just a small question. I have a high-rise tower and i want to apply this numbering to all floors not just the ones in the view. Also I'm trying to get to renumber them as 1, 2, etc.. at each level, like they restart counting at each level. Any idea how can I incorporate this in this script?

@AussieBIMGuru 3 года назад

Given each floor is probably different I'd suggest a circular numbering rule instead. Otherwise you'd need to draw many splines. If your rooms are all in the same order, you could pull their geometry down to the XY plane and the spline and run them all as sublists using the same logic as I use with one level here. You could then append a list of prefixes to each sublist per floor. Alternatively, circular numbering may be a better alternative approach which is more automatic: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-2H6BPi9gsQE.html

Try sorting with levels set to @L2 and longest lacing applied. I believe that might be necessary in some Dynamo builds due to changes since I made this video.

@julienzabala365 Год назад

Hello community, I am turning to you today because I have a problem. I would like to make a numbering of the parts thanks to a script but when I launch it, it numbers everything, no problem, but it does not follow the spline that I have set up. What did I forget in my script? Thanks again :)

@AussieBIMGuru Год назад

My guess is that maybe the spline is not at the same plane as the points, check in 3D in Dynamo. Also test a smaller model to see if in principle it is working.

@0letii 3 года назад

Thank you for the video! I am trying to apply to Areas instead of Rooms and it does not work. I have replace the word Rooms for areas in the Code Block and I applying it to a view of area plan. Is this correct? Should I do anything else?

@AussieBIMGuru 3 года назад

Not quite so simple unfortunately. Areas don't typically yield their geometry in the same way as rooms. Check out the area boundaries node in Rhythm though as an alternative for getting their boundary curves.

@0letii 3 года назад

Thank you! It worked!! But sometimes it missed some areas (even though the spline is cutting the boundaries) and other times it changes the order and does not follow the path of the spline. Why could it be?

@AussieBIMGuru 3 года назад

@@0letii hrm im not quite sure. Could be a variey of reasons. Make sure to join the area boundaries as polycurves so they are only intersected once per area, and also pull the curves to the same plane as the spline curve in dynamo.

Hi mate, I'm trying to make it work for assemblies; however, since the moment I have to place Room, the finish boundary doesn't work anymore with assemblies. Is there any way to adapt this to assemblies?

In my case rooms are having opening in between them, how to avoid double polycurves for such rooms, this is causing error at sorting due to difference in count of rooms and intersection points lists

@AussieBIMGuru 2 месяца назад

To solve this one, get the list of intersection points/parameters for each room vs the spline and get the lowest number from each list. This way you only get the value the first time the spline intersects each room vs every time.

@fernandogarciadonoso4695 2 года назад

Hi! First at all thanks for the video! is super helpfull and you explain it great, I´m trying to aply that to my project and i get an error in the Intersection Node, "Warning: Geometry.Intersect operation failed. Unable to make wire from edge body : WIRE_SELF_INTERSECTS2 -- Wire has self-intersection" i have no Idea why is that happening, so the scrip runs great by simple rooms geometry but in my case the rooms boundary has almost 50 points... i dont know if that could be the problem.. Thanks in advance for any help :)

@AussieBIMGuru 2 года назад

Yes unfortunately dynamo can sometimes fail on complex forms. In my experience there sometimes isn't a good solution for this, substituting the room with a bounding box or trying to get the room's 3d geometry might be an alternative.

@alexrafie7805 4 года назад

in the first method, what if you have a column in the room. that will create a curve within a curve. that will lead to a null index when converting to closed polycurve. how do you solve this?

@AussieBIMGuru 4 года назад

Hi Alex, you could collect the polycurves of each room, sort by function (area) @level 2, then return the last curve of each list. This would return the outer curve only.

@alexrafie7805 4 года назад

@@AussieBIMGuru thanks for the quick reply.. I trying this method on Spaces and I couldn't create a polycurve from the list that contains two curves. so I intersected the separated curves with the spline and kept the list structured based on the spaces surfaces. the only problem here (and I think in the case of rooms) is when you have the spline runs across a room separator. in this case you will get two points in the same location and that might lead to incorrect numbering. so to avoid that, I added a note to the users not cross a room or space separator.

@AussieBIMGuru 4 года назад

@@alexrafie7805 I did some testing and I see what you mean - space boundaries aren't easy to turn into polycurves like room boundaries are. I'll send my approach by LinkedIn PM, I think using the solid geometry of the room is the best way, and it should be able to work around space boundary lines.

Great as always man! There is something wrong i am doing Gavin . Just followed your example and my corridor do not get number 1 ..

@Iosconvolto 4 года назад

at 9:26 if I type 1 (rather than 0) i get corridor as n.1 . In this case as the last room (top right of your plan) has just one intersection, by typing 1 (so actually selecting the second intersection point) I get an error because the last room (top right of your floorplan) has just one intersection. SO I extend my spline outside my drawing in order to achieve the second intersection point of the last room. But maybe i am doing it complicate. PLease let me know your thoughts ;-) cheers

@AussieBIMGuru 4 года назад

@@Iosconvolto Hrm strange... the way I've done it should yield the first time the spline enters or leaves a room's geometry, so it should pick up the first time it 'leaves' the corridor this way. The range is built to be adjustable, so the numbering is determined by the range plus the offset later on. If your corridor is coming out as 0, adjust the range properties instead of the list level logic I'd say. The reason your last room doesn't get detected when set to index 1 @ level 2 is because it only has one intersection as you've identified. Feel free to send files to me for review if you like.

@AussieBIMGuru 15 дней назад

If you're using list.firstitem, try lastitem instead for the intersections (or vice versa). If you're not sorting the sublists by their value, do that also so you get the lowest value from each list of parameter values only.

would the second method work on ac units?

@AussieBIMGuru 4 года назад

Yes you could get the bounding box of the element, to cuboid, centroid. Then map that a common plane (pull to plane) - this lets them be measured only in XY plane. From there it's the same workflow essentially.

I am having issues when the spline crosses over a corridor multiple times it is not ordering the rooms in the desired sequence.

@AussieBIMGuru 3 месяца назад

This would require you to take the first intersection per room only, so that it only gets counted once in the spline path. This can be achieved if you get the intersections per room, sort them with their parameter by key in sublists, then take first item from each sublist.

Main thing would be to double check that it definitely gets intersected first (check on the graphical output in dynamo), and that only the first intersection is considered if it crosses back over the room afterwards or as it leaves it.
