Calculate Revit excavation using Dynamo!

Man... Thanks for existing 🙏🏼💪🏼 I love watching your content a learning along

Glad you liked it :)

I've been looking for this at some point! Thanks Gavin!

You're welcome!

I do have a question.. would you please help me out with it... I'm a landscape architect and need to have the fill and cut ... So far, I want to know if there is any way to create a building pad that follows the floors on the site( we use floors to create the slabs on the site and use Modify Sub Elements for creating the slabs which they have the calculated slope based on design and regulations!) So the floors are not flat ... but the building pads are .. If there is a way that we can use to have these building pads, they follow these floors that would be helpful for us to have the excavation amount on the site (these floors sloped in different directions) Please share your insight with me ... Thanks in advance, and I learned a lot from you

[@AussieBIMGuru]

Not that I am aware of, generally pads are flat in Revit. You could always assess excavation volume for modified floors with sub points though. Get the total volume of the floor as a solid, divide by its thickness and then multiply by the exacavation depth - this would return the volume of soil if the floor profile were extruded downwards without needing to.

@AussieBIMGuru thanks .. May I ask another question .... Is there any way that we can caculate the mass between floor and topo by Dynamo? The floor is on the topo and inside of the topo ... Is it possible to caculate the amount of this intersection between these two by Dynamo? Thanks in advance

Amazing workflow👍.

[@AussieBIMGuru]

Thanks Imran!

[@zagvot]

wow can i use this in some tie beam/column for excavation calculation purposes?

[@AussieBIMGuru]

Probably, as long as there is solid geometry that supports intersections it should work.

No matter what I do I can’t get my head wrapped around Dynamo ... any advice?

[@AussieBIMGuru]

It can take a few tries - I didn't really get it until my fourth attempt. Begin with a simple challenge you need to solve to make your work easier, having this context is the key to having the 'eureka' moment. A good workflow that helps nearly everyone is using Dynamo to make sheets from a document register, this tutorial I made might help; kzbin.info/www/bejne/q5OboqKZqpWtn7M Beware of common traps also when learning Dynamo, I wrote an article on them here; www.bimguru.com.au/post/dynamo-mistakes-to-avoid Most importantly, find a time where you can learn without interruption - I know this is hard during the working day. Take an hour or two after work, or on the weekend to try and learn more.

Thankyou so much for the Tutorial. really helpful channel and i already subscribed. I have one question regarding the excavation values. How can we export these values to the schedules? For example i have one site and on the same site i have two building (B1 and B2). How can i schedule the excavation for both the buildings separately. Thanks you so much again. which package can i use to do this? i am new to the revit and Dynamo.

[@AussieBIMGuru]

The best package for controlled exports to excel would be bumblebee. Unlike the standard excel nodes it preserves the original file layout so if you know the cell you wish to populate and the file you wish to target it can do this much better.

Thank you very much. You´re amazing!!!!!!

[@AussieBIMGuru]

You're welcome!

[@jevhid]

Amazing workflow, thank yuou for the video! I ran into challenge with calculating solid volumes myself. The issue I face is a difference between calculated volume in Dyanmo and imported solid in Revit. What can be the reason for it and which volume should I assume to be right?

[@AussieBIMGuru]

I would usually be inclined to believe dynamo over revit, depending on the scenario. These days I use Rhino for this workflow as it is faster and more effective. I made a tutorial for this about a month ago.

[@In-Equilibrium184]

Look! I found the hidden treasure.

[@AussieBIMGuru]

X marks the spot!

[@mohamadjouma]

amazing video but please slow down a bit for newbies like me to understand dynamo, loool

[@AussieBIMGuru]

50% video speed might help.
