Properties for attaching analysis results to a DataObject

alex-d-richards · 16 September 2025 19:48

Hi, experimenting more with the grasshopper nodes.

we have a workflow where we were extracting structural analysis results in this case from Robot structural analysis using the BHoM for columns and to share them with our third party designer through speckle.

there are ~904 columns, each with 62 load-cases and each with 15 properties that we were looking to capture so in total

904 x 62 x 15 = 840,720 data points

Initially i tried to use the properties to create effectively nested object/ properties to combine but ran into two issue:

im not able to attach a list of properties only base types
very long compute time ~1hr

as an alternative i did a bit of data manipulation to store lists of each property.

this resolves the two issues before but im not sure this is the most useful way to store the data?

And filters don’t work as filters in the viewer dont work as on the list of values, instead of the specific values, possible to be expected?

just wanted to check if there were better ways to achive this?

Thanks

Hey @alex-d-richards,

Nice use case and test for properties! Your initial setup is more intuitive and should work. Let me have a look and see if I can address issues 1 and 2.

Cheers,
Björn

Thanks for looking at this @bjoern i will dm you the sample file of above with data internalised.

@bjorn thanks for your time earlier. I was able to replicate the nested analysisResults structure you presented for Etabs using the pass through nodes and without the need for Lists.

In general the pass through component seem much more performant, with each calculations <0.5s for the same dataset as above!

Will be good to see how the Property component compares following your updates.

Hey @alex-d-richards,

We released v.3.9.2 today which includes that speed improvement for the Create Speckle Properties . Give it a shot and let me know!

Interesting that the passthrough component was much more performant! When I tested the Create Speckle Properties on your dataset, I was getting solve times of about 1s, which is still double the passthrough component’s time.
