get Entity name , ( string )

[rodrigo_sjc_sp]

i have this code

 

 

(setq selpline (ssget '((0 . "INSERT"))))
  (setq m 0)
  (repeat (sslength selpline)
      (setq entbh (ssname selpline m))  
      (setq lentpl (entget entbh))      
      (setq tipo_l (cdr(assoc -1 (entget entbh))))  
)

 

 

Unable to collect the value of the variable entity in tipo_l

when I try to use it more of an error

Error: bad argument type: stringp

 

How can I work with this value as a string?

i have this code

 

 

      [color=darkorange](setq lentpl (entget entbh))      [/color]
      (setq tipo_l (cdr(assoc -1 [color=royalblue](entget entbh)[/color])))  
)

there is no need for the line in orange color since you have it with entget function or visa versa .

 

The entity you want can not be string , so what are you planning to do with it as a string ?

You can convert any data type to a string using the vl-princ-to-string or vl-prin1-to-string functions.

 

However, since an entity name is simply a pointer to the DXF data in the drawing database, it is useless when the pointer is lost through converting it to a string or when not assigned to a variable.

Hi! Is there a way to convert back the string to data type, making the inverse of vl-princ-to-string? Thanks for the help

How would you distinguish what the original type is? 12345 could be a string originally or a number for example?

"12345" (atof or (atoi

It depends on the target data type - for example, as noted in my previous post, you cannot convert a string representation of an entity name back to the entity pointer - you would instead need to derive the pointer from the handle or object ID.
