I would like to create a function that finds characters or labels within the boundaries of a slab.
In Autolisp, there is a function called ssget that allows you to find characters by selecting something within the boundary in the form of a window.
Then how should I do it in archicad API?
What should I study?
I would appreciate it if you could let me know.

Otherwise, it has the insertion point and angle of the text or label. Can you find Slavs with this?
(What I want is to find the slab based on information about the insertion point and angle of the letter or label.)

Let me ask the question differently.
Can I select a slab based only on coordinate values (ex 3,3)?
