I have created block and that block I have use as a insert block. For insert block I prefer CUIX.File and VLSIP.
Through CUIX I have set symbol in Autocad ribbon and the same block used through LISP for shortcut command.
When I used through CUIX I got correct block layer properties. I mean I have created in "xyz" layer. Using through CUIX I got the same layer in my new drawing. If even my current layer is 0 but they still put "xyz" layer in my new drawing. This is correct for me.
When I use LISP shortcut command for the same insert block. If my current layer is "ABCD" then block properties has changed automatically. The layer of blocks has changed into current layer.

Dear master, is any command available to get the name of lisp command. That is,

I have created above program without using if and progn functions it worked and got the same results of coordinates on vertices of polyline. Can you please explain why you used both functions if and progn in your program?

In the program, sublist is the defined function or variable.... I am not seeing sublist declared as variable anywhere in the program.... Your method of teaching is very good...

[mesuttasar]

"sublist" word is function or variable which used in lisp?
