Assistance Needed with Lisp Routine in AutoCAD2025

[mruPRQUJ]

Hi there,

A Lisp routine that previously worked is no longer functioning. I’m using the same version of AutoCAD, and even when I use the original Lisp file, it still fails to run.

The error message I receive is:

error: AutoCAD.Application: Key not found

Please see the attached Lisp for your reference.

Could you please advise on how to resolve this issue?

Thank you very much in advance for your help!

Best regards,

When I load & run your lisp function I immediately get this:

Can you provide these linetype definitions & a sample dwg to run this function on?

[mruPRQUJ]

Please see attached line type file and a sample dwg, thank you very much for your immediate response!

[mruPRQUJ]

sorry,  linetype definition is not correct, please see attached linetype definition, many thanks.

missing xref:

I enter LINETYPE command and attempted to Load your acad.lin file & I receive the following linetype definition errors:

Then I successfully loaded the linetypes that are good into the dwg:

Then I run your lisp function and receive no errors:

I followed your instructions, it works now. It could miss some linetypes in the drawings. Thank you very much for your great support!

Have a great weekend! 🙂

Make a DWT and load your linetypes into that, a DWT is just that a template dwg that has everything you would normally use in it, its easy to do a purge and remove stuff compared to getting errors like you experienced. a last comment you can set your DWT as the default to be used when you open cad or point to a directory where you have multiple dwt's and pick correct one to use when you type "new". Our DWt had 220+ layers, similar number of blocks and acad & custom linetypes. Look under "OPTIONS"
