There are several different types of files available for importing:



Images: jpg, png


Go to File > Import (Ctrl + I) and select the image. Images are placed on the ground as blueprints, giving you a framework to build your environment on.


    • Press I to show or hide the image.
    • Press PageUp/PageDown to change the size of the image.
    • Press Ctrl + PageUp/PageDown to move the image to a different level.
    • Press Ctrl + Arrow Keys to move the image.



Environments: dxf (currently beta)


Go to File > Import (Ctrl + I) and select the .dxf file.


    • AutoCAD 2000 and later versions are supported.
    • LwPolylines and Lines are supported.
    • When you import, you can choose whether the lines become walls or barricades.



BIM Models: ifc


Go to File > Import BIM (.ifc)... (Ctrl + Shift + I).


    • BIM (Building Information Model) files are loaded into a new Smart Crowd model. They can’t be loaded into an existing model.
    • When you import, you can optionally enter the ground dimensions of the new model and an X and Y offset for the converted BIM model.



3D Models: obj


Go to File > Import 3D and select the .obj file. If the .obj comes with a .mtl material file, keep the two in the same folder so the materials load.


While placing the model:


    • Press Left/Right to rotate the model 90° in either direction.
    • Press + / − to make the model bigger or smaller.
    • Press Up/Down to raise or lower the model.
    • Click to place the model.


Clicking a placed model opens the 3D Object dialog, where you can:


    • Enter X, Y, Z coordinates to move the model to an exact position. X and Y are the position on the site in metres, and Z is the height.
    • Click Add Texture to apply an image (jpg or png) to the model.
    • Click Color to change the model’s colour.
    • Click Wireframe to show the model as a wireframe, so you can see heatmaps, trajectories and avatars underneath it, for example under trees or covered walkways. To make every 3D model wireframe at once, go to View > Toggle Wireframe.
    • Click Delete to remove the model.


Note: 3D models are only for visual purposes. Avatars do not interact with them in any way.


Note: the model file saves a link to the .obj file rather than a copy of it. If you move or rename the .obj file, it won’t load the next time you open the model.
