unity-ifcengine's Introduction

Unity-IFCEngine

Import scripts for IFC files.

Features working:

Geometry
Project scale in Milli, Deci and Centimeters
Assign materials according to material definitions in Unity component
Get georeference latitude, longitude, elevation from IFC file

Feature ToDo:

Read IFC materials and create Unity ones accordingly
Read IFC properties and make them usable

Note: Implementation is based on my IfcEngineWrapper project, which is currently not available as OSS, and IFCEngine http://rdf.bg/ifc-engine-dll.html?page=products Please see the license terms of IFCEngine DLL before trying to use this project.

Installation

Create a new Unity 2017.2 project
Import CielaSpike's ThreadNinja from the Unity Asset Store: https://www.assetstore.unity3d.com/en/#!/content/15717
Download this repository as ZIP file and extract it to the project root OR
Download a release package from "Releases" and import it using Assets -> Import Package -> Custom Package
If you've used a release package, copy the contents of IFCImporter/IFCDefines to the Unity project root directory
Open the IFCImporter/ExampleImport map to see how it's used!

Usage

The import scripts basically consist of the files ImportIFC.cs and MaterialAssignment.cs.

Create an empty game object
Attach the ImportIFC component to the game object
Attach the MaterialAssignment component to the game object
Assign the MaterialAssignment component to the ImportIFC component
Change the length of the material array and add defines for "IFCClass"->"Material" (case sensitive)

Create your own scripting class, calling the component and using the Init() and ImportFile() function
Use the callback function to do further stuff, when the import is finished.

Note: Objects created in play mode are not persistant to the game world. However, prefabs will be created upon initial import, so you can then drag and drop them in editor (or write your own serialization method). This may be needed to change texture scaling because of auto-generated UV coordinates.

Import some IFC files!
Access common IFC properties via the IFCVariables component attached to the child gameobjects

Release

Be sure to include the IFC2X3-Settings.xml +.exp and IFC4-Settings.xml + .exp, IFCEngine.dll and IfcEngineWrapper.dll into your binary directory!

Windows Build - Error parsing IFC File

Hi, Thanks for the Great Work

Can you help with Error parsing IFC File on Windows platform?
It works fine in the Editor.
Fixed a couple of small issues during the build.
But this one is related to dll which is closed for editiong.

I've tried both builds 86_64, 86.
And Dot .Net 2.0 instead of Subset.
Any Ideas?

Bellow you can see full log from the app which is pretty obvious.

Thank you very much!
