Need a tool for creating 2d outlines for complex 2d drawings

[Ankit Pandit]

Hi everyone,
Ankit here.

I’m currently looking for a reliable solution to generate 2D outer boundaries for complex drawings in AutoCAD. The solution should be:

Highly accurate (able to capture minute details)

Efficient in terms of performance (handling large/complex drawings smoothly)

Capable of working with imperfect geometry (small gaps, overlaps, etc.)

I’ve used tools like TotalBoundary earlier, but since it’s no longer purchasable/accessible, I’m exploring alternatives.

Does anyone know of any plugin, LISP, or workflow that can achieve similar or better results?

Any recommendations would be really helpful. Thanks in advance!
