You're welcome! Yeah you would need to isolate the reference elements using Revit API. There are a few nodes in genius loci for extracting references but I haven't tried them with curtain grids yet, see how you go though.
Yes it may be difficult in awkwardly shaped rooms though. There is nodes in Clockwork to get the walls around a room, then you'd need to filter them down to the left/rightmost walls at a specific angle. You can get their reference dimensions using Genius loci.
i have a problem, in false ceiling we generally provide gypsum border and then calcium silicate tile of 600x600 size such that no cutting of tile is needed. can we model it in revit and schedule area of gypsum and calcium silicate separately. Any help would be appreciated. i have already got polycurves showing room perimter. thereafter we need to calculate distance between opposite sides and check whether it is multiple of 600 or not.
An easy way to check the offcut distance will be using the modulo operator (%) which returns a remainder. Automated modelling is much harder as the room might not be square or rotated against the bounding box, in which case using the room edges would be a better approach then developing an algorithm to estimate room orientation and work across that direction instead.
Hey pertaining to this method, is there a way we could add "Remainder Dimensions" and "Typical Dimensions: to a floor? by inputting specific values for the remainder and typical numbers?
Yes you could format the parameter if its a string, or divide the whole value and remainder into two parameters for each direction. Just some simple maths really, divide the size by the increment, round down/floor that and multiply by the increment to get the rounded size, and then use remainder/modulo node to find the remainder of that division.
I came up with an alternate graph that doesnt use bounding boxes and isnt restricted to N-S orientations. I used your Crumple nodes for this. I got Room Boundaries, then line.direction, then your node VectorGroupByParalell, then grabbed the longest length of each group (indexed), then I created shared parameters in my project and tag that were length and rounded to the nearest 1/2". I suspect you developed these nodes for this very reason actually :D the graph isnt great for rooms that jog around a lot unfortunately, and doesnt do good with polygons. Its like a 90% then spot check type thing. I wonder if you could just use dynamo lines to draw a rectangle around the points of the room curves and then grab those values.
Hello, this is very interesting!! you are really great. I had a question, what if we want for that "width - length" to become the "sum of the areas" of specific rooms, could you please show us? Let's say we have a building with 2 apartments per floor, apartment 1 and apartment 2, can we have 1 room tag that gives us the sum of the area of each apartment? I think it the same steps you did in this video but with some modifications: to filter the areas by a specific parameter for each apartment (i already created a shared parameter for that), then make the sum of these filtred areas. I would be very grateful if you can help, Best of luck
Yes in this case you could collect rooms, obtain a common value that connects then as rooms and then use the 'group by key' function, with the keys being the common value for each. Of each group, obtain the room areas (still as lists), then run a sum node @l2 to get combined area per group of rooms. Finally, apply a set parameter by name to set this area value to each group of rooms before you obtained the area. Levels would be @l2, nil, @l1 with longest lacing.
Hi ABG, I¨ve been looking for a way to tag rooms in section views with dynamo... any ideas? I´m able to get the rooms and desired tag position ,but none of the place tag nodes i´ve tried seems to do the job... i think they are intended for plan views only or for annotation tags, but not for room tags in section views... please your advice!
Try getting the view's sketch plane (clockwork/genius loci) can do this, convert to plane, and get the closest points on that plane instead using geometry.closestpoint. i think that should hopefully work.
Hi, Thank you so much for sharing! I built this graph, it works great, but I get negative values... is there a way to write in the formula that they will always be positive? (like absolute value in math)
Negative values are a bit odd, but if you trust the absolute values you can use the Abs node under the math area of the browser. This should convert to absolute values.
@@AussieBIMGuru Thanks, I used it and it worked. Does make you think though - if a room is around the area of the origin, then the math calculation might not represent the length, in case min is negative and max is positive?
Thanks for this handy workflow! After running this graph my 3D view shows blue rectangles with blue points at both the minimum and maximum corners. When I closed the Revit file then re-opened it, these blue lines and points had vanished. It seems these are not part of the model but only visual aids connected to Dynamo's geometry. Could you explain what these are?
Typically when inside Dynamo itself, you can enable both background preview in Revit and Dynamo. In Revit, blue preview geometry is essentially any Dynamo geometry with an enabled preview in Dynamo itself. You can disable this setting under View > Background 3D Preview > Available Previews > Revit Background Preview. I usually suggest turning this off, as the preview objects sometimes persist undesirably after closing Dynamo or reopening into a new script.
Unfortunately I'vd only built this for a cliebt so am unable to share it. It involves finding room orientation using longest average edge lengths and then running a similar study in a rotated coordinate system.
Hard to say, but my guess is you are feeding an empty list in from the boolean mask node. Make sure the out list has elements in it and if not go back a step and see why.
The first "category.byName" node fails on "Warning: Category.ByName operation failed. The category assigned to the map is already set as a different handle." error. I'm not experienced enough to know what that might mean.
Unfortunately I'm not familiar with that warning. Maybe make a thread on dynamo forums about it and see if one of the developers can assist. Alternatively try using a categories dropdown node instead.
Then you will need to analyze the edges of the rooms and find the edge orientation that is most common. From there you rotate the room geometry back by that amount, bound it, then rerotate it the other way. It's complex
Not quite sure what you mean - families are taggable in any orthographic view (plan, elevation, section etc.). A keynote or multicategory tag should be able to annotate them the same way in all cases.
@@kentmengchan6846 annotations only show in the view type they are placed in. If you want to see them in elevation you need to place them in the left/right or front/back elevation views also.
@@AussieBIMGuru appreciate your reply. Thankyou. But in the host family, the annotation only placeable on the reference plane. not the elevation plane. Once i load the family into the project. it will show the family annotation on plan view when i place the generic family on the slab (vertically). If i place the family on the wall(horizontally), the annotation will disappear on the elevation view.
Hi thanks is for sharing. Does anybody know why when I connect list.filterbyboolmask to element boundingbox turns into a warning. Warning says expects argument types
I'd recommend cross checking the inputs to the node are a list of rooms and a list of true/false outcomes. These are required in order for the node to function properly.
Nice & handy script to apply the dimensions to all rooms at once! Great work Gavin! 👍👏
You're welcome Alan!
I'm sorry you're not a mechanical engineer. You're telling great. Thank you.
Check out Sean Fruin's work maybe, he's a strong Dynamo user and HVAC engineer. His new package 'Sparrow' might be of interest also.
Thank you for this!
No worries!
this is a very great video thanks for sharing. Is there any way to auto dimension curtain grids and strong reference plane from the family.
You're welcome! Yeah you would need to isolate the reference elements using Revit API. There are a few nodes in genius loci for extracting references but I haven't tried them with curtain grids yet, see how you go though.

How did you got your width and depth parameters in your room tag. ?.
These are shared parameters, so i have added them via a shared parameters file.

i need tutorial Tag Area Dimensions please help thank you
because i can't take area surface with Element.BoundingBox
maybe i do something wrong..
Use the Rhythm package to collect the area boundaries, they are different to rooms as they have no volume
Would it be possible to see the script for the way you can make it more accurate that you talked about in the end by using the centre of the room?
Unfortunately I'vd only built this for a cliebt so am unable to share it. It involves finding room orientation using longest average edge lengths and then running a similar study in a rotated coordinate system.

Hard to say, but my guess is you are feeding an empty list in from the boolean mask node. Make sure the out list has elements in it and if not go back a step and see why.
For the corridor problem, can't we use a room separator and hide it?
You could, but you'd need to make more rooms to cover the area, otherwise you'll have building area that isn't accounted for.
