#au2013 #auinfra CI2848 New Civil BIM Workflows Using Autodesk® InfraWorks™, Autodesk® ReCap™, and the Autodesk® Infrastructure Design Suite

Room: Lido 3101
Type: Lecture

This class shows you how to use Autodesk InfraWorks software to create highly realistic and accurate context models for civil infrastructure projects that support a more efficient, productive, and collaborative design workflow. The class shows how to aggregate a variety of data sources in InfraWorks such as geospatial information, LiDAR data using Autodesk ReCap software, design data from Autodesk® AutoCAD® Civil 3D® software, and 3D models from Autodesk® Revit® and Autodesk® 3ds Max® software. Use ReCap to preprocess LiDAR data for other Autodesk applications. The class shows several real-world infrastructure projects where InfraWorks was used to support design and communication.

Geospatial data
Cadd data
Visualization models

Most models are easy to move with GIS data. Not so with texture mapped 3d models. 
Global mapper (blue marble)

Start with the GIS data. Drape aerial data onto terrain. Build a context model with good aerial and terrain data. 
Single precision systems and game engines prefer tiles of texture at specific size and precision. 
Project offset coordinate system (classic approach)
Scripts for moving geometry. 
Stops max artefacts and camera jumping. 
In navis. Units and transform. Numbers as negative!

New approach. Create custom projection using “prj” file
False Easting and false northing due to a square being projected onta an elipsoid. 
Custom projection. Civil 3d and map 3d
This shows up in all the other products. 

Application data workflows 
Tiles are 4096×4096 resolution. Not based on physical size. 
Render as video. Add text later and composite. 
3dsmax was used a lot. 
After affects or combustion used for compositing. 
Lidar into navis and recap optimised. 
Overlay planned model against scan
## Objects found in scan that were not on drawings. Stop surprises. 

Infraworks
Direct link to weogeo
Multiple coordinate system support. 
Good at blending multiple terrains. 
It can use shape files. Vector data for water areas and buildings. 
Supports many 3d data types. 

Manage surface layers. Define which coverages sit on top of the other. Stacks vertically. Likewise shape files for water need to be on top. 
Game strategy of having low Rez for context. 
Use images that have a prj associated as the header info can get destroyed in image editors. For aerial photos. 
Removal of shadows from aerial photos. Time allowing. 
Infraworks can then provide the lighting info. 
Save modelling by rendering plan views and apply as texture. 
Use shape data from 2d to make surface textures. 
Height from attribute and random colouring. 
Scripting within infraworks. 
Clipped/culled footprint file to remove existing buildings from proposed scheme. 
Created a palm tree in max and added them to style pallet
Tree survey shape file on a dot. 
On export check for “z up” in the configuration dialogue. 

Model extents. Model settings. Set interactively. Model settings tab. 

Custom styles for specific roadways. 

They have a workflow. Mark Kaufman for fbx coordinates 

Overpass scan too half a day 

Fbx with an image. Image then cleaned up with photoshop 
Use quick shapes as masks for unwanted image info. 

## Revit files are a problem but apparently the import respects view settings. But class on that here at au

Substation model captured in 8 scans. 

Just use the point cloud if things are not being touched. 

Using clouds in max and you can create clipping objects. 

It would appear that recap is single precision. When you first open. Click on advanced before you import. This allows you to point in current coordinate system and then set to project. 
Save clipping clouds as rcs not rcp
