Search all blocks and make a list of dynamic blocks with a linear parameter present

[Billibong]

Hi,

 

I'd like to search all of my blocks using autolisp to find any with linear parameters. I can get a list of blocks but don't know how to specifically search for linear parameter.

 

thanks

Hi Commandobill,

 

Thanks for the quick reply.

 

I'm using the Lee Mac code shown below and it returns a list of the parameter names and the values set for each one, which is great but I need to know which ones are "Linear parameters". Is there an assoc code for linear parameters?

 

Thanks-

 

 

 

 

 

(setq obj (vlax-ename->vla-object (car (entsel))))

 

 

(defun GetDynProps (obj)

 

(mapcar

(function

(lambda (x / v)

(list (vla-get-PropertyName x)

(if (= 8192 (logand 8192 (vlax-variant-type (setq v (vla-get-value x)))))

(vlax-safearray->list (vlax-variant-value v))

(vlax-variant-value v))

)

)

)

 

(vlax-invoke obj 'GetDynamicBlockProperties)

);end mapcar

)

yes, however, it's not so easy. see here.
