How to split a large file loaded from XML to load them in PowerCivil?

The file is 800MB, I am editing the boundary of the imported XML in OpenRoads but I would like to split this model in at least 5 models, is it possible to create square/rectangular boundaries manually? PowerCivil is v8 series 4.

Thanks.

So you are able to import the 800MB xml file into a Terrain in OpenRoads.  So you should be able to create a clipped terrain.  You could draw a grid system of shapes and use those shapes as the clip boundary.

Yes, thank you for your answer. How can I make the system of shapes and use them as boundaries?

BR Pedro.

Create a shape and then copy it as to make a grid of shapes.  Then use the create clip terrain tool that prompts you to pick a clip element..

EDIT: SOLVED, it was with EXTERNAL CLIPPING.

I created few shapes and 'Clipped Terrain Model (Element)', when extracting each Clipped Terrain Model (internal clipping) to XML, it is considering all the model or the sections taken are not well represented when importing XML terrains in PowerCivil.

I would like to split the model, so I can load the content of every shape as separate Terrain Model in PowerCivil.

Any ideas? Thanks!
