VASA - How to make pathfinding tool read other traversable elements

[ingrid_fr]

Hello,

I’ve been using VASA for Dynamo Revit because I am trying to simulate the distance that a firefighter will walk from any of the rooms in a fire station to the Apparatus bays in case of an emergency call. VASA works perfectly in understanding stairs and creating the path using the stairs. However, there are situations that the shortest path in real life would be through the use of a Fire Pole (sliding), and this what I’m trying to figure it out (see image to understand). Even if I put the fire pole in the “stairs” category, the pathfinding will read it as an obstacle and ignore it. Do you have any suggestions on how I could make this work?

I cannot attach the revit/dynamo file here so I am sharing a link for the drive in case anybody wants to download it. Dynamo Forum - Google Drive

Thank you

I think you have to create a “connection” to the floor elements so that VASA knows it can go through that path., so while it seems counterintuitive I would fill that hole around the fire pole with a piece of floor to simulate that.

With the floor it didnt work, however, your comment gave me the idea of creating a spiral ramp (wiith a very weird slope, obviously) and a small floor to give access to this ramp, and now it works! I just need to see how I can improve the visualization of this ramp in the model now, maybe hide it in all views

No need to put it in the model - you can create the solids in Dynamo from the curve of the pole directly, add that geometry into the voxel model before you start the path finding.
