Hi Sophie,

You need to create ObstacleCurves out of ClosedCrvs in Rhino. These are assigned via BReps to here:

Use Merge if you've got a ton to collect.

As Peng mentioned below, the quickest way to learn is to begin with his example scripts and build on them.

Could someone help me with a problem I have please. I have set up a simulation using the tutorial however my situation is different from the example and the pedestrians seem to go over the buildings as they can't tell that there is a plan made in rhino.How do I make them avoid the buildings and stick to the roads. If you need any more information to help please ask.

Hi, All,

There is an example package available for PedSim on Food4Rhino or here:

If you supported PedSim on BuyMeACoffee before, you will get an email with this package.

Hi, Mohamed, 

I think a good way to learn PedSim is by studying the example scenes and create your own scene in Rhino and GH. If you have any questions please feel free to ask here.

Hi Wang is there any tutorial about the using of PedSim please?

Hi, chrisk,

Thank you for the feedback. Unfortunately I don't think the current version can extract FanVision geometry or collect objects in people's field of view. I'll think about it.

Great plugin, thanks for sharing

I want to use the Persons' FanVision to define what objects are within a persons view. For this it is useful to have an option to extract the FanVision geometry as an option in DeconstructPerson. Any thoughts if this is possible, or how to use a work-around for this 0.07 version
