Grasshopper to Etabs Import- Loads fail to load

Speckle Help Help (Legacy V2)

Hey everyone,
I am very new to speckle and was struggling to apply frame loads to a truss model I developed. The model geometry works fine but the load component seems to be not working. I am importing to Etabs 2021 but have also tried importing to Etabs 2018, unfortunately it didn’t work in either versions.
Thanks

Hey @Aprasai,

Welcome to Speckle and the community! Feel free to introduce yourself to the rest of the community here.

Thanks for posting your question! We’ve made some updates to get this working better (see below for a little preview :partying_spockle:).

Once this is available for you to test I will let you know (should be this next week). I will also provide you with a little GH script showcasing the best way to approach the frame load application. Stay tuned!

Hey @Aprasai,

Update all installed connector versions to the latest please and give that a go. To get loads to work effectively please ensure the following:

Grasshopper Definition:

  • Give all your CSIElement1D’s a name attribute. This way we can know which frame elements are which and that we have a correct load application

  • Define your load component in Grasshopper similarly to below. The name of the LoadCase should match a predefined load pattern in your ETABS model. The positions are relative positions (0 = start, 1 = end). For the elements, provide the CSIElement1D you defined.

  • Order of information: LoadBeam should be the last component you wire into the send component.

ETABS Definition:

  • As mentioned, make sure that the load pattern is predefined in ETABS before trying to receive.

The sample script is also attached below. Give me a shout if you have and difficulties!
