The value of msg is We are sorry, results for these parameter values can not be exported, which means that the export request timed out. Likely this is related to size of the mesh you want to export.
Which type of account are you using (i.e. how much computation time may your model use)?
@snabela
We are using PRO account. In terms of computation time, our model in ShapeDiver is updated about 10 seconds, in Grasshopper is about 1sec, the delay is quite significant in ShapeDiver.
The to-be-downloaded model is 32mb in stl format, I manually checked the model size in Rhino.
Do you have any guidelines that what is the maximum model size that can be downloaded in shapeDiver?
