At 19:00 when I get stuck on the cost technique, I had a mental blank but luckily one of the viewers reminds me we can simply replicate the cost field using a formula (=Cost) and just total that column separately.
Hi, Gavin! I would like to suggest a subject for a future video. I am finishing my first project done entirely in Revit (2000 square meters) and I had a LOT of trouble extracting quantities from stairs and ramps. I still haven't quite figured out how they behave in what concerns schedules. If you could do something on the subject, I guess it would help a lot of users. Thank you for the excellent content.
Good suggestion, added it to the video list to make. In this case my technique will be to isolate all upward facing surfaces (landing/tread) and get their total area using Dynamo, then write that as a value to the stair. Volume of concrete is another option as well, but not as common of a takeoff method.
Great video as usual btw count can't be in a formula, as you mentioned so you can create a formula and name it anything u want and it contains "1" then formatting --> calculate total so you can add it to the formula.
Unfortunately I don't believe length parameters are naturally available due to the range of fitting types - for example, the way a t fitting is measured vs an elbow. See this thread which discusses some computational methods of estimating fitting length by connector point extension and revit api; forums.autodesk.com/t5/revit-mep-forum/question-on-duct-fitting-s-length/td-p/3615972
Great presentation! A short question, which is the best workflow to quiantify formwork?, it is modeling its geometry with dynamo, painting surfaces, or just by the geometrycal dimensions of the cast in place concrete?
I would think that given you are working off exposed faces, combining relevant element geometry in Dynamo and obtaining face areas might be the best method. You can assess the normal of a face in order to isolate relevant faces, for example in the case of a column/wall, the only relevant faces would be sideways facing, and for a slab or beam downward/side facing. You could also just union all your concrete as one, and assuming your beams/columns and slabs are all touching you could take all faces with a normal lower than Z and this would give all side/down facing elements. The columns would need to connect to the floors however, otherwise you would have exposed faces in your union that would not be formworked technically. I actually really like this idea for Dynamo, and will add it to my list of videos to make.
@@AussieBIMGuru Yes it's like that, i've done my own research and find out that doing it its actually very difficult, so i prefer to wait untill a pro like you reach to a good result. It was difficult because of when you make all the concrete geometry as one, have to first get only the faces (get a void from the elements) and then erase de parts of the pieces that will not be formorked, like upper mid sideways faces of a beam, or the joint of a beam and a column, and then assign the values to the respective elements in revit (since they lose they order when you join all the geometrys). Was too much for me hahah. Thnks for your answer!
@@JorgeRodriguez-wt4gu i've queued up a tutorial in first week of october to show a workflow to join geometry and omit upward facing faces of the joined concrete. I believe dynamo wont be able to handle the reassigning of faces back go elements as this would require a lot of intersections to match the subfaces. Rhino Inside/Grasshopper is probably a more efficient workflow for this level of geometry processing. I'll explore the workflow at a later date for this part but doubt I can get Dynamo to to this part, at least for large models.
@@AussieBIMGuru FYI when scheduling structural steel, it's more common to have weight reported. I use a genericaly named Shared Parameter (Type) that has a value for weight per length (kg/m'). This is a number parameter, that in schedules is multiplied with CutLength (or similar) to show element weight. Alsow I use this in rebar schedules (kg/m2 as well). It's much more practical and acurate then relying on Revit to calculate these things by using volume, and allsorts of mumbo jumbo withing the schedule itself. One more thing... Reacently I found out that you can create a Shared Parameter for Materials, and am curently working on some elaborate Wall (material QT) schedules. I'm realy interested to see how others do their Wall QT.
@@vukvukanic1095 ah this is super handy to know, thanks! My main client I do QT with typically uses wall QT for stud framing area, wet/dry lined area (we put parameters for dry/wet sheet count in wall type properties to multiply the area) and brick face area to determine brick count (50/sqm).
Just spent another hour watching another great video. Thanks Gavin. I know in UK QS uses NRM2 as measurement standard. My firm uses ASMM 6 (Australian standard methods of measurement of building works). What other QS standards have you encountered?
So far I've only properly used the standard methods as well when it comes to universally used ones. I've had some specific client systems for commercial private clients in the past however that differ slightly due to their procurement and estimation processes. Glad you liked the video Lee, and hope business is going well for NexSmart3d!
High level really, webinars dont tend to get in the reeds... i have a more in depth video which covers data and schedule setups for 5D here: ruclips.net/video/Ll9JvkUiGoA/видео.htmlsi=tiLeL98ReRdYqDZ6 If you want a general schedule tutorial, the webinar over at Revit Pure is decent: ruclips.net/user/livetiVbQfiy23I?si=SuzBcvFmTIlOMFDx
@@AussieBIMGuru great channel, I haven't seen those "time" and other dimensions here though. have you made any video about how revit models are handeled by other parties (contractors, construction managers) by any chance?
@@danielkrajnik3817 i will likely touch on these at some point, hoping to bring some guests to the channel eventually which might help give more immediate context to these fields.

Before I even watch this. Lemme say a Big Thank you for creating this Content
You're most welcome!
finally get time to watch. worth it. again great work.👍
Glad you enjoyed it Imran!

Haha indeed!
Great stuff. Cant wait for online courses
Thanks!
My Dynamo course is now available :)

How do we get the length for duct, duct fitting? There is only length show in duct but not in fitting
Unfortunately I don't believe length parameters are naturally available due to the range of fitting types - for example, the way a t fitting is measured vs an elbow.
See this thread which discusses some computational methods of estimating fitting length by connector point extension and revit api;

Great Video, very interesting. do you have 5D on Revit MEP?
Same reply as on the other 5d video unfortunately!
