3D Model of Network Dataset

AmanArora

Hello

I have a complete network dataset in 2D and now I want to make a 3D model of that dataset, is it possible to create a 3D model or visualization of 2D network dataset in ArcGIS 10.0? And if is it possible then please give me a solution to complete that task.

Your small help will be appreciated. 🙂

Please do not add true "z" data from a DEM to a building data as it will destroy the existing artificial Z's one may have to make a building with different floors offset from ground.

At a minimum, you need is a building line feature class with polylineZ for the hallway centerlines for you to route on and in addition, the stairs, elevator lines connected for the movement between the floors. You can have more as needed for restricted doors,etc. For visualization you may need other polygon feature classes to show offices, building, etc.

Does your data have Z values? Try running "Add Surface Information" using a USGS NED or a LiDAR DEM and then add to ArcGIS Pro or maybe ArcScene.

Thank you, george!!!!!

it is reaaaally useful the workflow you send!!!.

What I still don't get is the prerequisite my layers should have. I only have one layer, "building", and I don't really understand the requirements it needs.

thank you in advance!!!!

Hi Lidia,

We actually just recently released a sample workflow including tools to do just this. Check out the following link: http://www.arcgis.com/home/item.html?id=66cd6ea44302402c9eaad7ae0ad2bf72. In particular, see the pdf file inside the "Indoor Network Creation" folder. We're still actively developing the workflow and tools, so we welcome comments and questions.

Lidia,

You can have all the features in one feature class.You can use ArcGIS Pro's 3D editing capabilities to create and maintain such 3D building data.

Hi everyone!

I'm trying to construct a 3D network for building interiors (I'm absolutely new on 3D!!!), and maybe my question is so obvious, but:

do I need to draw on a separate feature class elevators and stairs??? In the example here: http://www.arcgis.com/home/item.html?id=d6bd91b2fddc483b8ccbc66942db84cb every floor is on a separate feature as floor transitions (elevators and stairs) and I would like to know if it is the only way to obtain routes inside buildings.

Thank you in advance!!!!!!!

ArcGIS 10 supports 3D networks. You need to have Z coordinates in addition to x,y on your line data.

You can read more about it here:
http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//00470000005q000000.htm

It also has location of the 3D sample network included with the Network Analyst tutorial.

Regards,
Jay Sandhu
