Cad lisp help

[ROBP]

Hi to all experts,

 

Need to get a feedback on this lisp i found that draws pipes ,elbows and tee's.

 

The problem i have is that once the lisp loaded in a new drawing, i get an error message that the center_lines when running it is missing therefore can it be fixed and get the lisp to create the green layer default cad center line created automatically.

 

Thank you for for your precious help and posting back the corrected version.

 

Best

In addition to being very poorly written, there are functions missing ( layercenter_lines layer0 layercenter )

 

The pipedata appears to be only valuable snippet and it needs to be rewritten and verified.

 

I would think that there are much better 2d pipe routines out there.

 

Unless that is you want to invest the energy into the rewrite. -David

Robp,

 

Here it should work more or less.

 

I went the lazy way and replace the call to the missing routine

with a (setvar 'CLAYER "Center Lines") or a (setvar 'CLAYER "0")

 

I agree with David that there are much better routine out there.

 

There is one here on Afralisp DDPIPE by Kenny Ramage

However it is a VLX and is for metric pipe.

 

Also this, as an early work by Lee Mac PIPE & FLANGE DRAUGHTSMAN

 

At least you'll be able to run it and make your own opinion.
