Surface Analysis Grids using Dynamo (Feasibility Part 7)

[@MrDrenahmeti]

Hi Gavin, thank you for the tutorial. Your included adaptive point family, at least the one I got from your git, doesn't have the parameters ABG... included so they won't be populated. Just a heads up. Thank you!

[@AussieBIMGuru]

Yes generally I'd assume people are adding or adjusting their own parameters at that step hopefully. I just made these as an example in this video. Glad the tutorial was helpful!

[@MrDrenahmeti]

@@AussieBIMGuru thank you, I assumed it would be the case. Also, when I am selecting the different faces of the mass instead of adding them throughout I am having the previous face adaptive point either deleted or for example only 1 row of adaptive family remains others get deleted. So as I rotate selecting each face the previous face gets changed, having it's point removed all or only 1 row remains! Of course, I have different size building that I did to follow the tutorial. All the best!

[@AussieBIMGuru]

@@MrDrenahmeti yes generally that is due to a thing in dynamo called element binding. I call it a bug but the developers call it a feature. Generally you will need to add a fresh node for creating adaptives a second time around, or run via dynamo player.

[@MrDrenahmeti]

They seem to work now! I made the massing bigger maybe it was small scale initially!

Hi Gavin, I’ve been benefitting from your channel for a couple of weeks now, since I’ve just started to learn Revit and Dynamo (coming from Vectorworks). Do you mind sharing with me your detector family? Keep the good work going!

[@AussieBIMGuru]

Update: i've added them to my github under the families repo

​@@AussieBIMGuru Hi Gavin thanks for this great learning source, I wasn't able to find Detector Family would mind put the link?

Is it possible to have Dynamo generate buildings with different shapes based on a fixed number of floors and floor plan area?

[@AussieBIMGuru]

It depends on the building shape really. If it's a box where the user specifies the width then yes it's just basic mathematics (area / width = depth)*floor count. Dynamo doesn't know what a building is by default, we have to build a script to tell it that. All it is is a program that tells Revit to follow instructions - we write these. It also depends what you mean by 'a building'. Is it just some floors and walls, or does it include a curtain facade? Maybe it needs a lift core, if so how does Dynamo know where to put it? Each step and requirement needs an extra part of a script - eventually it gets quite complex. If you're asking dynamo to make intelligent decisions based on site setbacks then it gets more complicated. At that point I'd be looking into Grasshopper or third party tools like TestFit - geometry isn't Dynamo's strong suit.

[@tiagos.8301]

@@AussieBIMGuru first of all, thanks a lot for the reply!!! So, I was thinking about using dynamos generative design to test some shapes using solar analysis as a parameter, so it wouldn't necessarily need to be a building, the shapes would be fine already

[@AussieBIMGuru]

@@tiagos.8301 I would suggest Grasshopper in that case. Ladybug doesn't work in Revit 2020+ unless you use Rhino Inside and is really required for detailed solar analysis.

[@tiagos.8301]

@@AussieBIMGuru I see. And would it be possible to then use Dynamo's refinery to try some different geometrys to optimize sun hours?

[@AussieBIMGuru]

@@tiagos.8301 not that I've found so far. Dynamo relies on the packages it has access to, and Ladybug isn't one of them. I usually use Galapagos or Wallacei in Grasshopper/Rhino for solar optimisation.

Hello Guru. I'm trying to follow your tutorial, but it seems like Lunch box is not available on the package manager in Dynamo anymore, and the one clic installer isn't working for me because I don't have Rhyno or Grasshopper. The problem is I tried to copy paste the content of the Lunchbox folder I found on the Internet into the Dynamo folder, but it seems like the Panel.PanelQuad node isn't available anymore. I tried to find a similar node on the package manager, but they always seems to lack an output or to have one more output than the original node you used in your video. I'm talking about the Grid.FromFace from the Clockwork package. Do you have any idea where I could find an identical node, or Can I make it work with the node I have? Thanks for your insight and your amazing videos, keep on feeding us knowledge!

[@AussieBIMGuru]

Yes unfortunately it is no longer supported. No simar alternatives as far as I know. Most users seem to have luck if they install it via package manager in revit 2018 where its still the old one, or via the source which can be found here: dynamopackages.com/download/528038ad3f7315936f000058/2018.7.7 Otherwise you'll need to ask the author.

[@karldal1961]

Hi Gavin ​@Aussie BIM Guru Thanks for your enriching tutorials I have question, I am trying to link these detectors with parametric pastern in dynamo in order to create generative design any suggestion how this might be? as parametric pattern working only in conceptual mass files?

[@AussieBIMGuru]

I would suggest you use the Lunchbox package to tesselate and measure at the centre of the divided panels as opposed to use the detector families. The families are only needed if you want to 'bake' the results to Revit. Also I'd consider using Rhino Inside and grasshopper as there are more advanced and quick workflows available for this type of thing. I have a video here showing an example workflow using galapagos in Revit; kzbin.info/www/bejne/bYDInXahoJKfj80

[@karldal1961]

@@AussieBIMGuru But as we created those Detectores and harvested the data showing sun hour, any way to assign those numbers to (reference points) ?! which get along with parametric pattern panels I see u mentioned Rhino unfortunately i am stuck with Revit and dynamo :)

[@AussieBIMGuru]

@@karldal1961 the reference points are what we used to place them, so to work generatively just do everything but place the families - use these test points in dynamo instead. Ladybug doesnt work in Revit 2021 unfortunately so you may find issues using this workflow in dynamo/gen design.

Hi Gavin I have a question regarding that if we have no.of points on a surface but if i want to exclude the perimeter points then how can we do it by filter by boolean mask or by any other method apart from just setting a offset to the points. And your videos are a real gem for the whole industry.

[@AussieBIMGuru]

There are a few ways this could be done. I'd suggest getting all 4 corners of each grid cell instead, and clashing them against the surface as a sublist. Count the number of true results in each sublist, and if any have less than 4 then they must go beyond the edge of the face and the corresponding cell can be filtered out based on this.

[@pratyakshshrivastava965]

@@AussieBIMGuru Thanks I did try with boolean mask but not getting the satisfied result instead I applied list.set difference node to achieve that.

[@MrDrenahmeti]

FYI for those who couldn't install LunchBoxe's latest version, try installing previous versions. It worked for me.

[@AussieBIMGuru]

They also uploaded the last supported version here: bitbucket.org/provingground-io/lunchbox-for-dynamo/src

[@MrDrenahmeti]

@@AussieBIMGuru That is great, I was about to give up until I tried the previous versions since the one in their website was for Grasshopper I think.

[@jessedellemann2939]

I can't get the package lunchbox, can you send it to me?

[@AussieBIMGuru]

It will need to be installed via exe; provingground.io/tools/lunchbox/download-lunchbox-for-grasshopper/ It should boot up an installer for dynamo and/or grasshopper.

Hi, is it possible to create toposurface by using dynamo? I mean choosing a map area location, generate a toposurface in dynamo and export to Revit?

[@AussieBIMGuru]

Hi Moe! It definitely is possible! Check out the package 'Dynamaps' by the company Data-Shapes. This is able to generate a surface to work with; dynamobim.org/dynamaps/ This uses the same source as Open Street Map, which is also used by a tool called 'CADMapper'; cadmapper.com/ I've got a tutorial on my channel where I show how to get this information and turn it into a topography (without even needing Dynamo). kzbin.info/www/bejne/jGi9ameliNaqmM0 Key points to watch (in the other video); 4:10 - CADMapper 6:15 - Clean up DXF in AutoCAD 19:25 - Create topography in Revit You may also find another video I have on my channel useful for site creation. You can convert OSM files into linework in Revit then export to DWG to essentially get a rough building/road map using Dynamo; kzbin.info/www/bejne/jHSXoWNqmsujpJI Dynamaps has also developed some nodes to do this more easily straight out of Dynamo to Revit. Hope that helps!

Hi Gavin, thank you so much for all these great videos! I have a question related to the sensors. I'm stuck in the final part of the video. When I try to generate my sensors, instead of following the list of points, Revit puts all the sensors at the origin. I'm not able to figure which part is wrong. Maybe my adaptive components are incorrect? Can you help me pls? I really appreciate that. Thanks again for your work!

[@AussieBIMGuru]

Maybe try with the family I keep on my repo here; github.com/aussieBIMguru/Revit-Files/tree/master/Families ABG_GEN_DetectorSphere_R19.rfa is the family I used. As long as the preview points you can see in Dynamo/Revit before you place the components are in the right place, it should work.
