VDC Modeler – Convert your 2D data into 3D

VDC Modeler is a parametric modeling engine that helps you convert your 2D data into 3D and produce combined, multi-disciplinary BIM models from various input sources. VDC Modeler is an extremely useful add-on to your VDC Explorer whenever you are dealing with multiple sketches and various data sources!

Easy integration and data import

VDC Modeler integrates smoothly to your existing tools such as Autodesk® AutoCAD®, Civil 3D® and Map3D®. You can import data in various formats such as open BIM formats (LandXML, IFC, CityGML) as well as generic CAD and 3D model formats.

Parametric modeling

With VDC Modeler you can produce 3D data out of 2D and GIS material. Convert CAD symbols to 3D objects and visualize your models automatically.

VDC Explorer - Combine all your BIM models into one

VDC Explorer is a stand-alone, easy-to-use BIM model management, design analysis and simulation software suitable for even the most demanding construction projects where multiple design disciplines need to be handled as one.

Multi-disciplinary model management

The work of each stakeholder is simplified with a combined engineered model, clear project structure (Groups) and easy navigation.


Collaboration tools inside the model include topics, topics attributes, commenting, cloud synchronisation and Collaboration Server.

Design analysis

VDC Explorer includes a set of functionality for design analysis, such as Object Info, Measurement, Value based clash detection and Sun shadows and sky.

Design simulation

With 5D simulation and Driving Simulation you can review and visualize the design.

Sharing of models

An easy to use export functionality enables the use of your BIM model in different environments. You can publish models with the help of the VDC Live model sharing platform or import them to other advanced visualization tools.

VDC Live - Share your models effortlessly

VDC Live model sharing platform allows you to share your combined BIM models and generic 3D models with an unlimited number of viewers. Publish models for private review or embed them to your website. Insert comments and control model functionalities and take the model with you on site whenever needed!

Easy and quick sharing of BIM models

VDC Live helps you publish your models to an unlimited number of viewers as generic 3D models or as more complex combined BIM models. You control all of the model functionality, and there is also a sophisticated comment sharing feature.
VDC Live utilizes WebGL technology which enables the viewing of models with any browser. Features such as Model browser, Navigation and Web viewer make sharing quick and easy.

You only pay for publishing. Viewing of published BIM models is completely free!

VDC Live app helps you view BIM models on site
