DWG 3D Points to Topo - Help, Urgent!

[barrie.sharp]

I've been asked to create a 3D file showing site levels and apparently it's urgent! I have been sent a DWG with 3D points but Revit ignores them in 3D! Can this be converted into a CSV text file or made so that Revit will see it? If this requires specialist software, can anyone convert the file for me?

Create a table of the points in AutoCAD, export them out to excel, then put them in x,y,z rows and save them out as csv files.

if they are far away from the origin I would them them closer note the original poitn of the original then update the co-ordinates in Revit.

I would only do this if you don't want to import the cad files or the cad file is large lots of layers and very messy easier jus to extract your selection of points from cad then trying to carve up the model,contours,drawing.


However it should be working fine with the standard import system in Revit.

What sort of point objects are appearing in cad?

Standard nodes I believe. How do you create the table of points?

Are you using the Toposurface>Create From Points File command? I'm really surprised that's not working.

I have tried that but no joy. I attached the dwg if you want to try. It might be something I missed.

These should work!

That really is helpful. Thanks. How did you go about preparing the DWG? Or do you use third party software for the task?

Revit doesn't create the cleanest topo does it. Wish topo was better developed.

It was imported in the wrong units. When in meters, Revit provides a decent topo

It was done with a 3rd party app called Foresight. It can create contours from a .dwg file.

I do most of our construction layout to help the supers out in the field. Pretty neat as soon as it is created I can tell them everything in location northing & easting where stuff is at. Center of grids, footing corners, pile cap locations, parking lot radius, if we can get the civil .dwg it helps us a bunch.

Thanks for the link. Looks expensive It is a shame that Revit can't read dwg points. Surely that suits the software as much as a txt survey. Sites are definately a big part of architecture.
