I am looking for a tool that will plot all of my objects and properties into an ERD format which can be edited in real-time to build out my HubSpot portal. I understand that there used to be a "data model overview" which seems to be similar to what I'm looking for. I've found a third party app called "Schema Grid" but it seems to be low quality and also is unable to connect to HubSpot as of now.
For mapping the objects you can use 3d party tools like Lucidchaart, Miro, Mindmap... Schema Grid exists in the HubSpot App marketplace and can be connected to HubSpot easily to display all the Objects information with the help of schemas if a standard HubSpot Data Model is not enough for you.
We generally build our ERDs in Miro (which is manual - but helps us learn the data model intimately), and I think it's not a great idea to map every single property on every single object.
What is the use case here? Documentation?
There is a HubSpot Data Model Tool as well, would be a good idea to explore that 👇🏻
