You can try the GRASS command v.in.dxf in Processing or in the Grass plugin (look at GRASS GIS: import DXF). Some results in GRASS GIS with 3D dxf files: from Vector support in GRASS GIS: Möbius strip visualization to show the 3D vector capabilities of GRASS 6 - imported from 3D DXF (screenshot: M. Neteler) or geological layers (3D dxf) (my work ...
Grass GIS v.to.3d function is one solution. Based on a height values it makes 3D vectors. Than you can use Grass Nvis to view the data. Other option is to script a rendering pipeline. whose the first steep is to transform 2d vetors to 3d objects. The complex way is to use a software like Blender 3d. The easy way is to make a script that extrude the ...
Take a look at OSM Buildings. It's works with Leaflet and Openlayers. Here you'll find a short introduction of a implementation with building data stored in PostGIS. There also exist some 3D-Mapping libraries based on WebGL: OpenWebGlobe Cesium WebGL Earth
There is a Google SketchUp to ArcGIS tutorial available on YouTube which may help you do this in ArcScene if using ArcGlobe is not a mandatory requirement.
You can import the models from sketch up or a cad file that is designed in 3d. The key for models in ArcGIS is multi patch. If going from sketchup export to kml. What you're after is the colada (.dae) file. A kml can be renamed to .zip and you will find the dae inside. If importing from cad just make sure the file has 3d units, and dwg will work fine. ArcGIS ...
This is not as easy as with ArcGIS but you can use; Nviz from the GRASS plugin (cf. Micha comment) but you need to know GRASS GIS (look at the illustrations in GRASS-Wiki: Vector 3D polygons indicated by Micha). Some geological examples: 2 polygonZ layers and a raster (2D) draped over DEM (3D) extruded volume from the two layers Boreholes ...
A quick Google search turned up: Spar Point Group has a nice writeup on several web-based point cloud viewers at http://www.sparpointgroup.com/blogPost.aspx?id=3879 This viewer is just too cool: http://lidarview.com/ PointCloud looks promising, and supposedly is free: http://pointcloud.io/
You could look at Cesium. A local city GIS office showed a demo of an LiDAR point cloud using Cesium at a recent conference. I don't recall if you could measure in it, but you could at least zoom, pan and rotate around.
