Lisp Won't Stay Loaded

[erin0karr]

I'm new to installing and using Lisps, I don't know what took me so long as I've been getting my CAD on since hs, I'm now 30. Anyway, I have noticed I will load it and a few minutes later have to re-load it as it's not recognizing the command anymore.

 

Thoughts? I'm sure it's user error.

Read that. It might help.

That just confirmed I have it loaded correctly. I guess my next question is, why do I have to re-load all the routines every time I close and re-open a drawing? I also noticed if I load a lisp in one drawing, it doesn't load it throughout CAD. I still have to load it in every open drawing.

I'm only on AutoCAD LT so I don't know much about LISP. Sorry if I cant help very much. Just look for the "Overview of AutoLISP automatic loading" in the link.

It's all good, any help is appreciated Tuns. Hulk, I'll give that link a look at over my lunch break. Duty calls.

Would it be alright if I asked... are you on a job for A&M regarding the stadium they're building? Or adding to I should say.

[erin0karr]

Nope, the architect isn't local.. I could completely be making this up but I want to say they're out of CA.

[Tuns]

Ah that's good. That job is going to be a huge cluster ****. We didn't bother bidding it because of that reason. The architect is Populous.. and they look to be a global company.

This is because AutoLISP (& Visual LISP) runs within the Document Namespace, i.e. for every open drawing, there is an allocation of memory set aside for AutoLISP in which every defined function, variable & symbol is stored.

 

In this way, the same variable or function can hold different values in each drawing (namespace), without any inteference since the symbols cannot interact between namespaces.

 

For information on how to automatically load a program when a drawing is opened, see my tutorial here.

Perfect! Thank you Lee Mac.

Ah, TAMU...what wonderful memories of College Station, and a girl named Veronica who took me to the creamery on campus for out of this world ice cream.

I don't go there, I work for an architectural precast company so I was just aware that they were adding to the stadium. I just noticed that he is from College Station so I thought I'd ask.

Go to Options -> Files -> Support File Search Path

 

Then add and link to the location of your LISP. I moved mine to the 3rd one down from the top because we have our main support path and then custom hatches.

Personally i load them in the CUI file under lisp and also add it in the option search path.

And it never fails it always loads everytime i open cad and call for them.

The position of a path entry in Support File Search Path list will matter only if there were resources (auto-loaders, AutoLISP routines, linetype libraries, hatch patterns, blocks, etc.) with the same name in two or more folders from said list. This is due to the fact that first encountered will be the one used.
