2. Creating a complete VDC model

In this tutorial you will go through all the steps to create, analyze and simulate complete virtual design and construction (VDC) model created from geographic information system (GIS) maps, AutoCAD / AutoCAD Civil 3D objects, Autodesk Revit models, or using data from any other design package that can be exported into open data formats like LandXML / IFC (industry foundation classes). We use AutoCAD Civil 3D platform, because Modeler part is currently supported only on AutoCAD based products. Some examples can be also carried out with AutoCAD, as Modeler can be installed onto AutoCAD based product (or vertical).
Because this tutorial covers the whole range of Viasys VDC products, ensure that you have installed (or can access) the following products:
  • AutoCAD Civil 3D (AutoCAD);
  • MAGNET Modeler or VDC Design (includes MAGNET Explorer or VDC Explorer)*;
  • VDC Live (web-based service);
  • Any other design package that can export LandXML, IFC from legacy design formats.
*In the text the products are referred as Modeler or Explorer for simplicity.

Please refer to User Guide > Getting started to get more information about installation procedures/requirements.

In this tutorial you create the complete virtual design and construction (VDC) model that can be used for various analyses as well as collaboration workflows. The tutorial covers the following topics:
  • Modeling of existing situation:
    • Terrain with orthomapped images, buildings, forest areas, utility networks.
  • Modeling of proposed designs:
    • AutoCAD Civil 3D corridor and pipe network (water & sewer) models (or a design from other other package that has been exported into open standard format, LandXML);
    • Autodesk Revit structural models (or a design from any other package that has been exported into open standard format, IFC);
    • Converting 2D designs into 3D, like landscape objects, lighting, road signs, road markings.
  • Creating a combined data model from all existing and proposed disciplines
  • Collaborating using integrated collaboration tools
  • Clash detection analysis to detect overlapping design disciplines
  • 4D/5D simulation of construction phases
Based on tutorial content, it is divided into the following subtopics:
  • 01_Creating_submodels
  • 02_Combined_VDC_models
  • 03_Model_analysis
Tutorial files can be downloaded from: Creating a complete VDC model Tutorial files

If you download tutorial files and extract those to you hard drive, you should see the following main structure:

Note: In your daily projects you can use/define your own project structure that merges with local/national standards. This tutorial has a very basic folder structure, where each subfolder includes tutorial starting point and also a final version of the sub-task. MS Excel file ProjectStructure.xlsx is for general referencing purposes only.

It is important that before you start with current tutorials, you include a given separate Textures folder to your Modeler and Explorer texture path table.

In Modeler, select from the main toolpalette: Tools > Texture Paths...


In Explorer : View > Settings (double click on Textures link)

Texture Paths (VDC Explorer)

Once you have completed this tutorial, your VDC model should look like the image below:

Final VDC Model

Because each sub-folder has a starting point and a final version of the task, you can basically do those examples in any order. You can also move directly to the folder 02_Combined_VDC_model or 03_Model_analysis and see the VDC model in action.

Note: If you open up the final model from a folder 02_Combined_VDC_model or 03_Model_analysis, you may get a warning that some links can not be found. It is due to the fact that you have extracted those sub-folders to some other location. Therefore you need to fix those links only once. We look that later in the tutorial. If you are sharing a complete VDC model, you usually generating a model package, in which case such problems do not appear.
