How to Fit Text Inside a Polyline?

[santhoshr151194]

I need to place text inside a closed polyline while ensuring the following:

1. The text always remains inside the polyline, regardless of its shape and size.
2. The text size adjusts dynamically based on the polyline dimensions and text length.
3. The text is optimally positioned within the polyline (centered or best fit, I have attached a few images for reference).

Is there any existing AutoCAD API method or utility to achieve this?

Any sample code or guidance on handling this efficiently would be greatly appreciated.

Your example has similarities in that they are polygons that have opposing sides that are parallel and are connected by short sides, almost like Road lines. How easily you can do this depends on how many assumptions you can make about the shapes. The solution to The more General problem description is not trivial, meaning that if the shape can have any number of sides, identifying the optimal position or placement of text is a bit more complicated.
