Presentation by GIM at the FME World Tour 2019 in Leuven

1. Validation and
visualization of
Revit BIM Models
Aurélien Mairesse

2. What is Revit
Software used by architects,
engineers, … to create Building
Information Model (BIM).
“Revit BIM software includes features for architectural
design, MEP and structural engineering, and
construction. Revit supports a multidiscipline,
collaborative design process.”

5. RVZ
Direct Revit reading
with no intermediate files

6. The story
A nursing home building (BIM)
created with Revit.

7. The story
A city planner, an architect, an engineer or a
facility manager wants to visualize how the
nursing home building looks like in its
neighborhood, and share with the local
community.

8. The story
Luckily the building will
be implanted in Namur,
and the city has its own
3D model.

12. Convert Revit BIM to
Cesium 3D tiles

13. FME and 3D
● FME supports a growing range
of 3D formats:
IFC, REVIT, SketchUp, DWG, CityGML,
COLLADA, Wavefront OBJ, glTF, I3S, Cesium
3D Tiles, VRLM, 3DS, etc.
● In total 36 formats

14. FME and 3D
● Visualize 3D data
● Format translation
● Database loading
● Data transformation from 2D to 3D
● Integration of BIM, CAD, LiDAR and GIS
data
● Sharing and publishing 3D content
● BIM / GIS integration
● Geometry model conversion
● Build surface model from DTM or LiDAR
● Drape 2D features on surface
● Extract max height from DSM per
building
● Extrude from surface to height
● Coloring and texturing of surfaces
● Powerful xQuery options
● 3D validation + repairing
● …

17. What is Cesium 3D Tiles
• An open specification by AGI that allows
for efficiently streaming 3D geospatial data
on the Web
• Submitted as an OGC Community
Standard
• 3d syntax based on glTF
• Each tile is described by one JSON file
with CRS, attribute, and refinement
information

22. Validation of Revit file

23. Cesium viewer
It is a web application that uses the
cesium javascript to vizualise 3D tiles
combining ortho pictures and elevation
model.

25. Namur 3D CityGML to
Cesium 3D tiles

26. What is CityGML
● CityGML is an open data model and
XML-based format for the storage
and exchange of virtual 3D city
models.
● The aim of the development of
CityGML is to reach a common
definition of the basic entities,
attributes, and relations of a 3D city
model.
