Hi there,
I'm replicating an r/c building model with Robot 2013 to see how well program performs. I successfully meshed and run analysis however the generation of calculation model takes way too much time.
I'm meshing the model in an horizontal elements first and vertical members afterwards fashion and local meshing is done in a snap. Model generation reaches %50 in 15 minutes but takes additional 2.5 hours to reach %65 and finishes overnight. The time consuming step is "Attribute assigning (panels, solids)"
Model is originated from revit and I put many arbitrarily placed line loads on floors... can this be the reason? Or is it just normal at that step to spend such amount of time (> 5 hours) to produce the final model?
I've attached the model file, may be you can check that to find an erroneous thingy inside.
Thanks for your helps

These can be the reasonso my suggestion is to replace 3D loads by linear on egdes (example : http://screencast.com/t/EEON097e).
I am checking model because after 10 minutes I have 94% of model generation.

Yes, FE linear 2p(3D) loads cause the problem -> case 4 in this model

Maybe not exaclty they but maybe their number (number of records in loads table) 961.
Using API I have convetred and compacted them into 4 records of linear loads on egdes.

Hi Rafal,
thanks for your in-depth analysis of the problem. After your first post I revised the model and eliminated those line loads and issue disappeared. However in Revit I find it a breeze to place and manage line loads. I didn't understand why it’s got messed up...
If I would have created those line loads in robot, would I have the chance to take them back to revit as editable load elements?

It is not messed up. Just every load is created as a separate record.
Also try to avoid using non-hosted loads in revit.

They will not be lost if you import model to revit but these loads will not be visible in it. If you export model later to robot you will see them in robot.
Macro attached
Due yo small bug in program the list of object is not automatically assigned to load records so it mast be done like on this example movie (of course for all these records): http://screencast.com/t/YhQkwjV9
Hello.
I don't understand how I should use the macro to get edge loads from 2p loads. Can you explain this to me please?
Thank you.
