[@colinhutton9704]

The holy grail for me is getting the same exercise, but for Linked IFCs. More often than not we get vendor models created in something other than Revit, therefore, need to be using IFC. Being able to locate an opening based on linked IFCs this would be fantastic.

[@AussieBIMGuru]

Dynamo has the ability to interact with IFC to some degree (albeit limited, and dependent on class mapping), but unfortunately Revit is not a great program for handling IFC files, especially if not class mapped properly. I would suggest looking into Geometry Gym for Rhino, and forming workflows in Grasshopper instead (using either Rhino Inside or native Rhino modelling). Someone has built a workflow here though (but I suspect for a big IFC file it would struggle); learndynamo.com/mod7/

Super Amazing. I've made it work to me also. The only thing which doesn't seem to work well is the tolerance. It's always the same no matter what I choose.

[@AussieBIMGuru]

Hrm that's strange, it's really just there in increase the width/height of the final opening so cross check that the formulae it relates to receive the value and change when it changes also.

[@Vasoulinho]

@@AussieBIMGuru Tried the script on another, much larger project. The Geometry.Intersect node returns an empty list... Googled the thing, scaling down, intersecting and scaling back to normal size didn't work. Seems like Revit and Dynamo do not like huge coordinates... Any experience with a workaround? Cheers!

[@AussieBIMGuru]

@@Vasoulinho usually the only way to handle it is to enable large geometry scaling in dynamo. Short of that you could locally adjust the coordinates by a common xyz offset (using add point node or add as a vector) to get your elements closer to a workable location. Revit has a comfort window of about 14km, anything beyond that and it tends to be problematic.

[@digitalengineering1971]

Hello, thanks for posting. I am only just getting into Dynamo and this script supported a task I was looking at and was really helpful, Thank you. I developed it for my specific needs, however I have encountered a couple of challenges. 1 - using the centroid from the intersection geometry is different from the centroid from the combined bounding box geometry. I found this out when combining multiple penetrations through the wall, the bounding box option as the placement point seemed to work better for me. 2 - Also, for some reason the centroid seems to reset to Dynamo 0,0 if I select penetration geometry that totals less than 80mm which it seems odd, and I have not figured this one out... I thought you might like the feedback, I am probably using the script slightly differently so it might be how I have set it up.

[@AussieBIMGuru]

Hi there, good point - the bounding box centroid is probably the best placement location in all scenarios, I think I made an oversight if I used the geometry itself. The error sounds very weird, is it for the geometry specifically, or the bounding box as well?

[@digitalengineering1971]

Aussie BIM Guru It did it on both items. Really weird. I re-built the script and it seemed to solve it. I must have had something off in my script. I had re-worked it to adapt to the inclusion of Fabrication Parts in the elements selection option, as these come through as mesh not solids, so I need to adapt things to suit.

[@AussieBIMGuru]

[@AussieBIMGuru]

Yes if you add parameters to the opening family you can write these properties of the penetrating element to the opening upon creation.

[@Turamiar]

1:15 We also have a third option which is using Void. I want to learn your thoughts about that. Thanks.

[@AussieBIMGuru]

Generally voids require inplace massing which is not available to the revit API or dynamo. Wall openings would be the fallback in lieu of windows but require a fairly different approach to mine.

[@Turamiar]

@@AussieBIMGuru Thanks. This graph is fairly useful. If we work around would it be possible to select multiple walls stacked together and create a single or multiple (small depth) window openings.

[@AussieBIMGuru]

@@Turamiar most things are possible, comes down to your programming knowledge. Personally i always program this a while at a time so users review the outcome before moving on.

[@bigkieth23]

Great video again, can this script be modified so that it reads a linked model & gets the intersection of a pipe or duct element & place the void family you made to all the walls in the model in one go?

[@AussieBIMGuru]

It could be, but would require a lot more work. You'd need to get the linked element geometry ans filter it down to the walls you care about, then use a similar workflow to this, but set up to handle multiple walls/elements at once.

As long as the wall and the element have some sort of intersecting geometry it should be possible. This workflow relies on that in order to find the bounding box around that overlap.

[@theonetalal]

wonderful video!!! Thanks mate. But is there a way to create penos for Fabrication Parts? A Fabpart Duct for example is not a solid but a mesh. How would you do the intersect test on that? Would love to get an answer.. or even better a video on that. :D :D :D

[@AussieBIMGuru]

Generally I've found meshes to be very problematic in Dynamo, I'd likely switch to Rhino Inside Revit there if I had to work with more complex geometries as it's far more capable in Grasshopper/Rhino of working with mesh natively. In absence of that you could try mesh toolkit in Dynamo, but I suspect fab parts would give very inconsistent intersection geometries typically in Dynamo.

[@vrbaac1641]

very awesome tutorial ^^ but is this possible if the wall is in a linked file? thank you very much ^^

[@AussieBIMGuru]

Yes it would, it's a slightly different workflow though, you would need to be in the model with the wall(s), then select the elements from the linked model instead. There is a great node in the springnodes package called 'SelectLinkedElements' which can achieve this.

[@AussieBIMGuru]

Thanks! Unfortunately due to bounding boxes in revit always being axis aligned, we can only measure the zone of penetration by rotating our intersection to be lined up with the dynamo Y axis. If we measured a bounding box at an angle, the size would not be true and correct, as it isnt parallel to the wall.

Great workflow...!! Would that extraction of geometry for walls and other elements when you have a huge building project be costly..? I previously had an experience while tying to extract geometries of furniture inside rooms. My system with 16 GB ram and Core i7 7th Generation with 4GB Graphics just crashed. Tried three four times with no success. Since then I am afraid of extracting geometry...

[@AussieBIMGuru]

Yes for larger projects this could be taxing on system memory. Usually anything that gets all elements in active view or of a category in excess of 250 can be slow, same goes for geometry. Where possible I suggest narrowing the number of elements you get geometry for at once. This workflow is OK as it only needs two elements' geometry at once per run so project scale isn't really a factor.

[@eeennn2007]

1. if several services are selected at the same time, one large opening will be created. the issue is when the service are separated with some distance, the opening will be very strange and very large. How can we improve it at the dynamo? is there any demostration? 2. if the above item 1 is fixed, we can try to select multiple penetrating services and multiple host elements for creating wall openings.

[@AussieBIMGuru]

Hi Edward, you're correct in identifying that there are a lot of ways to improve and enhance the workflow - this video is just the start of something bigger and more complicated for most people I'm sure! This video was really made to show the concept of bounding box axis rotation and the general principle of creating a 1-off penetration. Another workflow to enhance the script is an 'update' to pre-placed penos, so dimensions aren't lost. Grouping services automatically can be quite complex, as it means the script needs to be built to recognise when something is 'close enough' to something else, but also to be able to run this on a mass basis (for each element, consider every other element). See this thread where someone 'solved' this challenge: forum.dynamobim.com/t/sort-lists-by-proximity/23031/6 From here, you would instead group each 'list' of elements as geometry, then union each sub-list, and run the same process as this workflow, but for each sub-list. This can be done by either working at levels, or by applying functions on a 'list map' basis. It's quite complex, but if I get around to solving it I'll let you know. I would suggest that instead of selecting all penetrating elements, you look into the clash nodes from the Bimorph nodes package, which can obtain all elements intersecting something such as a wall (without taking too long) and then continuing forward with all elements of a particular category(ies) only. From there you could also filter for minimum sizes (min. radius, or min.width/height) as we often ignore elements smaller than a certain size in peno generation (they just core hole instead on site). Hope that helps!

[@dusanodalovic3905]

Amazing work! GJ Does it work for MEP links?

[@AussieBIMGuru]

Thanks Dusan, this workflow doesn't support links, however with a few adjustments to the front of the script it can. Linked element geometry can be obtained using a clash check vs the selected wall from Bimorph nodes package, then carried forward from there. I"ll create a video at a later date to show how this is done!

Need your help how to solve this if I need the same script to run multiple times on same dynamo or revit session.

This behavior should only occur when the script is run from dynamo itself, due to what we call 'element binding'. There is no easy way to fix this behavior. This shouldn't happen when run from dynamo player. To be sure, try refreshing between runs of the script and see if that helps.

They all have nodes that do these functions - if it isnt resolved by this try using their version of these nodes instead anyway See a thread here with similar issue/solution: forum.dynamobim.com/t/familyinstance-byface/5993

@@ahmadsaid8594 unfortunately i am on holidays and changing jobs next year so have no access to dynamo until february. Suggest hitting up the dynamp forums in the meantime; lots of helpful people there. Also check lesson 1 of my dynamo series; i cover how to find/install packages there.

hello there, @Aussie BIM Guru I followed your instructions for creating a script, but the intersection of solids from MEP and WALLS geometry shows an empty list. Could you please assist me in resolving this issue? I'm a new Dynamo user.

[@AussieBIMGuru]

This workflow only works if the walls are in the same model, im guessing yours are linked. Linked models is a complex workflow, I suggest focusing on fundamentals first if you are a beginner.

I saw that the height and width parameters are of istance, but in windows family is type and built parameter. they are not editable as an instance. How to do?

[@AussieBIMGuru]

Assign the parameter to a dimension, select it and you can tick on/off instance from there.

[@marcofrancescofalbo287]

Thanks for answering me. Forgive me but I did not understand ... the Height and width parameter are a type parameter and you cannot change them as instance parameters. how do you change them?

[@AussieBIMGuru]

Maybe this thread will be easier to understand than my explanation: forums.autodesk.com/t5/revit-architecture-forum/can-i-make-window-height-width-into-an-instance-parameter/td-p/2001881

Just follow the process and edit the window family. I cover the video tutorial by @BIMGURU. you can watch it on my channel or do some cover yourself.

I encourage to share your scripts if you cover others. I use github usually for this myself.

Yeah you dont really help with somebody to get started.

[@AussieBIMGuru]

This isnt a getting started video. Maybe try out my dynamo learning series playlist. Learn fundamentals before taking on full workflows - dont rush.

[@cathychoi6959]

I started 2 months ago, to watch Gary's tutorials, some of his class I watched 3-5 times. Every time I see things new and important. 😀

[@AussieBIMGuru]

Thanks for the words of support! Can't please everyone, but always great to know it helps some people out there 😀

[@lennonsc77]

Another great post! Everything works great until I got to Springs.HostedInstance.ByPoints... this produces a null and I can't figure out why. Its causing an error in Element.SetParamterByName (dereferencing a non-pointer). I'm running Dynamo 2.16.1.2727 if that makes a difference. Can you help at all? 🙂

[@AussieBIMGuru]

Hrm I used an older version of Dynamo for this workflow, my best guess is maybe there's an API update that the node isn't able to account for. Double check you're using the latest package version, beyond there dynamo forums can be good for troubleshooting custom packages.

Hi Same issue for me did you find a solution
