I’m running Dynamo 1.2.1 on Revit 2017 Two questions here, the first a little more intuitive than the last… First, I have not been able to find a way to interrupt a run of a Dynamo execution once it begins, is there some simple keyboard command or button I can click to stop a run? – for clarificati…

I believe the consensus is that code is faster than nodes. DesignScript and Python are the way to go for faster computing. Also, break up major tasks into multiple graphs. Running multiple manageable graphs seems to be faster than running one big all-encompassing graph.

I dont think you can stop running. I’ve tried it hard once and did not found nothing. About the speed, see this topic: [image] 1.3 speed FAQ Is it just me or 1.3 seems insanely slow compare to 1.2?

Thanks for the response. Would you mind explaining what you mean by running multiple manageable graphs is faster than one big one? For your reference - My code is reading from Revit, reading anywhere from 10 - 150 sheets from on Excel file, (the number of referenced sheets changes dynamically based …

That might not be something you want to break up. But I believe I’ve heard that splitting up tasks makes Dynamo run faster as the computations tend to build on each other. Dynamo keeps track of all changes at all times. So the more individual functions in a graph, the slower the graph runs. For exa…

Agh. I think I’m tracking now… this is my first time I’ve used Dynamo so I’m only slightly familiar with its terminology; to clarify, when you say “it would be better to split each task to its own graph”, is a graph a new .dyn project? or is “its own graph” refereeing to a .dyf custom node file?

Sorry, a graph refers to a new dyn file. Custom nodes really don’t speed things up at all I don’t think. They just make complex node functions prettier to look at.

Thanks, I’ve stumbled across the “graph” terminology a few times throughout other forums and my understanding has been a bit hazy until now. So how exactly would one go about linking an output of one graph to the input of another? Would the Dynamo Player be the key to bridge the gap? I have only see…

Not a stupid question - a very important one actually. You can’t really connect the the inputs/outputs. You have to break your graph at reasonable points. Usually this involves exporting to Excel or committing changes to Revit. Then the next graph in the process reads the information again from eith…

I see… That seems to be a pretty big flaw in the Dynamo system… with a database as large Revit being such a big aspect of Dynamo, you’d think they would get some run time optimizing features in the out of box capabilities… The ability to link up multiple different Dynamo projects without having to o…

You have to remember this isn’t all Dynamo’s fault. Running that many computations in any program is going to take time. Just think of if you were doing all of this manually in Revit… how long would it take? Revit still has to do all the work in the model.
