Use the new link topography command revit 2019 1 and later.
Civil 3d solid to revit floor.
You can export the surface data into an xml file and import that into revit or you can link the autocad data from civil 3d as background information in revit.
In the extract solid from surface dialog box select a tin surface to use as the basis for the solid.
If 3d solids do not display as desired in revit.
A combination of published surfaces and linked cad files containing extracted corridor solids provides both surface information and detailed geometry.
For export solids as select one of the following values.
For example if you create a level at the elevation of a typical.
Linked cad file of corridor solids in revit.
This also transfers into revit when the link cad option is used providing a more detailed representation of the curb island inside of the revit model.
However there are two approaches you can take to bring these surfaces from civil into revit.
Back in civil 3d use masselement to convert the 3d solids to one or multiple mass elements.
We sometimes try to link import 3d cad model into revit file but we face the issue.
While inside the 3d view from step 2 use the convertto3dsolids to convert the pipe network s objects into 3d solids.
Revit is not able to read civil surfaces directly.
Click file tab export options export setups dwg dxf.
Use the solids tab of the modify dwg dxf export setup dialog to specify how solid geometry in 3d views is exported.
Export the civil 3d drawing to standard autocad format exporttoautocad.
First of all geometry in a 3d dwg file imported or linked directly into a revit project has no category assigned and therefore will not be cut.
Alternatively you can select the pipe network and explode it twice.
Sharing topography between revit and civil 3d revit help topic simplify the civil topography to autocad standard data and import.
Click the solids tab.
Exports all visible revit geometry as polymeshes.
The extracted solids are generated per subassembly shape providing the ability to set a different material or style to each piece.
Click surface contextual tab surface tools panel extract from surface drop down extract solids from surface find.
That it comes as a giant block doesn t obey any view range or any other revit concepts.
To export the data and import it into revit select export to landxml from the output tab and choose exactly what data you want to export and then import into your revit project from the site designer tab.
Tin surfaces and tin volume surfaces can be selected.
