Скачать или смотреть Save Hours! From PDF to Pathfinder in a few clicks

Importing building geometry for an evacuation model doesn’t need to be slow or painful. In this tutorial, I show you how to go from a PDF floor plan to a BIM/IFC file and then into Pathfinder to run a complete evacuation simulation—all in just a few clicks.

You’ll see how to:
Convert a PDF drawing into a 3D BIM/IFC model
Export and import geometry directly into Pathfinder
Check scale, walls, doors, and exits for accuracy
Populate the model with occupants and run the simulation
Visualize results in 3D and adjust assumptions (pre-evacuation times, walking speeds, exits)
