Since we are on this topic, how would I make an agent that does this job:

I am writing an automation software that interfaces with a legacy windows CAD program. Depending on the automation, I just need a picture of the part. Sometimes I need part thickness. Sometimes I need to delete parts. Etc... Its very much interacting with the CAD system and checking the CAD file or output for desired results.

I was considering something that would take screenshots and send it back for checks. Not sure what platforms can do this. I am stumped how Visual Studio works with this, there are a bunch of pieces like servers, agents, etc...

Even a how-to link would work for me. I imagine this would be extremely custom.

No joke you should ask one of the latest thinking models to plan this out with you.

What controls the legacy CAD app? Are you using AutoLISP? or VB scripting? Or something else?
