Revit 2024 Tutorial - Analytical Modelling

- In this tutorial we take a look at producing an early analysis model prior to the creation of any physical structural elements. This is ideal for the engineering team when developing a structural frame.
I really hate the new workflow for analytical models since they only gave us a broken script for automating it.
Same for me
Thanks for the tutorial! Would you please also make a tutorial for analytical modeling of concrete structures where the beam members are connected with rigid links from the column face to the centroid of the column cross sections (rectancular, L-shaped and Z-shaped column sections etc). Also maybe include split level in slabs, with a 2D member for the Z-shaped deep beam connecting the two slabs at the split level.
If i have say a rectangular column 230x750 at a corner carrying 2 adjacent beams, how do i ensure the insertion point of the column coincides with that of the beams
The column will be a single 'stick' and your two beams will node into the top of the column
my revit not showing Analytical model option. how can it walk up?
Hi. I had drawn all the elements how i can convert the structural members to contain analytical Model ????
I don't use this capability. I find it better to model directly in Robot.
This is useful if you use multiple analysis tools. Also, it keeps the model coordinated with the physical model which is needed for more complex jobs.
@@RevitStructureBlog right
Can someone please tell me how to get analytical plans for each level? I create the same 2 level building in revit but theres no "Level 1 - Analytical" only the simple level 1 and 2 . How can i get this analyticals levels in my structural plans??? Thanks all.
Hi, basically, you generate new plans for each required level and then apply the analytical model template. The plans are not generated automatically.
Ok and how to apply analytical model template in a specific level? thanks @@RevitStructureBlog
@@felipelemes5843 you can select the view in the project browser, right click and select the apply template properties
I want to try to create ramp panel but i d'ont know how to use it with the extrusion tool. If you can show some examples with stairs.
You can create a section or elevation view and then create a panel by extrusion. Just make sure you are in an elevation or section view
@@RevitStructureBlog I will try it.
Would have been interesting to see you do it with different serial sizes. I'm currently trying to draw an analytical frame with varying sizes and all of the analytical lines are on the centroid of the geometry with no way of setting to a specific level - seems kinda useless.
It doesn't matter what the section size is with the analytical members. All the elements will be drawn on the same plane. When the physical model is created you control if the members are top of steel, bottom of steel etc.
@@RevitStructureBlog I blame frustration but I should have specified that I'm attempting to utilise the Autodesk 'generate analytical model' dynamo graph and it is very much is putting all of the analytical lines on the centroid - both in 23 and 24 irrespective of the tolerances and options picked in the graph. I could no doubt draw it manually on the correct plane, however then I'm in the realm of "why not just draw it natively in the analysis package". Okay it won't be dynamic, however in this case it's an existing building so that isn't an issue.
It just feels as if they've taken a massive leap backward. All it would take is the option to 'set line to level' and 'set line to grid' in the properties. I appreciate that theoretically their dynamo script has that option, but after hours of fiddling with it yesterday, it doesn't seem to work.
@@nicebikemate ah, thats a different case! Yes, the analytical model generation graph for 2023 & 2024 is not up to the job. Autodesk have rewritten this for 2025 which is a big improvement. However, to generate the analytical lines for the framing you can get the location line in Dynamo which will follow the physical model. For example, if all your steelwork is justified to top then the location lines will all be at the top as well.
@@RevitStructureBlog Yer that's what I ended up doing, frustration slightly subsided. Thanks for the responses.
For the analytical model you can't create the columns using the "AT GRIDS" option and for the beams use "ON GRIDS" option to make it faster instead of placing each one by one? All you have to do is draw a crossing selection across the grid lines.
I am sure all these extra features will come in future releases.
@@RevitStructureBlog What I mentioned on my comments regarding adding columns and beams by crossing selection the grid lines already exist in Revit. I'm not sure about analytical model.
@@arkinimation6394 Hi, yes, this is currently available for the physical members but not the analytical members at the moment.
