ACAD.LSP

ACAD.LSP


ACAD.LSP is a special file of AutoCAD. It is automatically loaded as you start a new drawing. And what is in it, is performed.


Loading AutoLISP Files


Suppose you have a program, that you are using all the time. You can specify in the ACAD.LSP file that that program is loaded.


Add this line to the ACAD.LSP file:


(load “-/-----/-----.lsp”)


And the program is loaded as a new drawing is started. Just enter the name of the AutoLISP program, to start it.


You can even specify the complete AutoLISP program in ACAD.LSP. If you do, the AutoLISP program is load into AutoCAD automatically.


Global Variables


Maybe you are working with global variables. That could be variables of your own or AutoCAD. You can set their value here.


Giving Information


Or maybe you want to give information to the user at the start of a new drawing. Have a line that starts with PRINC.


You could add a line like this:


(princ “\n---------------------------”)


IntelliCAD


Maybe you are not working with AutoCAD. Maybe you are working with IntelliCAD. You will not find ACAD.LSP in IntelliCAD.


But IntelliCAD has got ICAD.LSP. In IntelliCAD that file has got the same function as the ACAD.LSP file in AutoCAD.


Other AutoCAD Alternatives


There are more alternatives for AutoCAD. And those alternatives do not have the ACAD.LSP file. But you can look for a similar file.



In Windows do a search for LSP. You will see the file that is used as ACAD.LSP is used. Open the file and see for yourself.
