Civil3D fbx size

[Anonymous]

I did a quick search and did not find the answer, so if you know of a previous post about this topic, I apologize!

Basic:  I am trying to import a very large fbx file developed from Infraworks surface contours to Civil3D about 89 MB, in an attempt to analyze & design an entire Town's Pressure Pipe Network.  I thought it best to gather surface data from Infraworks, and import it into C3D as my surface, prior to creating my network.

An attempt to Import the fbx file into Civil3D, it seems to just have the hour glass... for quite a while.

So my idea was that I should break the fbx into separate areas (not the most ideal situation, as the contours will then be broken apart), but that was my quick genius idea... lol.

So I really just want to know what the maximum size fbx Civil3D will be able to handle as an import.

Or, if there is some other workflow that you deem as a better way, please let me know!

Should the Infraworks fbx data (ground, buildings, corridor and all) be imported all together as one block?  My attempt above was only for the ground data separated out...

Export out as IMX instead. IMX works better between the 2.

I tried the IMX export, since my model is 135 MB, I don't think Civil3D wanted to import it, (assume it's because it's such a huge file).

My IMX file is 570 MB large.  Guess my next question is, what is the largest IMX file that Civil3D will handle?

Are you clicking the Refine Selection button and unchecking stuff you don't need?

Thank you, I will try that next.  Right now just bogged with cutting the pie into the largest size pieces as possible, in an attempt to see what's the largest size it will take! LOL
