Hi guys,

Is anybody have experience same issue as mine?

however same member that i previously update from robot I need to update it again in revit as the member change in size bringing it back to robot using add in update model from revit structure.

I got an error like:

object reference not set to an Instance of an object.

Could you attach the original Revit model and describe step by step actions to follow in order to reproduce this situation and tell which versions of both programs you use?

hi Arthur,

in Revit what ever additional elements we did. sending it to Robot we use the plug in in analyze tab and RSA->RSA link send send only current selection.

whatever the changes in size in Robot, in Revit we need to do is to use same plug in but now is the update whether whole project or just part of it.

same procedure in Robot, what ever changes in revit in size or location of the same element. I use Add in-> integration->Autodesk Revit Structure to capture the updates done in revit. and used the plugin to send new elements created in robot.

hi Arthur,

thank you for the response.

1st time export from Revit to robot will not be a problem. i dont have any problem either.

after you export the file to robot. try to change 1 of the element in revit and from Robot, could you use the add in to update the element.

that will error happen.

cheers,

mark
