Isovist on Dynamo

Hi everyone, I’ve been googling and struggling to make isovist script on Dynamo.
Realized its much easier to do it on Grasshopper but want to make my own for Dynamo since I have few models that are in Revit. Rhino.Inside is currently not working / error on updating.

Space planning toolkit has a node for this: RefineryToolkits/README.md at master · DynamoDS/RefineryToolkits · GitHub

Hello everyone thank you for the replies.
Space planning toolkits is a dynamo package right? or is it something that’s included in Revit 2021? I heard Revit 2021 will have isovist function built in.

Space planning toolkit is a package. Not sure what the requirements are but they likely are listed in the package description, and are almost certainly on the GitHub.
