How to specify an object is to work as a ground surface

When I try to walk on a Civil 3D corridor, I fall through unless I have also created a surface model of the corridor. Is there a way to specify that the corridor itself is an object that can be walked on?

Hello tcorey,

 

Navisworks needs to have a surface mass of some sort for collision to interact with. If you have gravity turned on, you will fall until you interact with an object. So, if you have a corridor with no mass to walk on, you would fall as there is nothing to interact with. If you turn off gravity, you will not fall.

 

I am not sure what your end goal is in this particular situation, if you are just walking around, turning off gravity after you reach the desired height is probably the way to go. If you were looking to try and make a walkthough of some type, I would make a viewpoint animation and let Navisworks take care of the camera movement.   

 

Thank you for participating in our community!

So now we have the ability to incorporate Recap scan data into Navisworks. Even though Recap can identify a group of points as a plane this is not transferred to Navisworks nor would it exhibit any sort of mass I believe. Does anyone have a suggestion for the quickest way to create a surface with mass so the gravity capability in Navisworks can be used? Make a floor or surface in Revit to possibly match the scan plane?
