Get block object from nested object

[SteveK]

Sorry I'm sure I've seen this question asked before, but now that I want to know it I can't find it.

The question is: if I have a nested object, what is the best way to get the block object that it is within?

 

thanks!

Hi Steve,

 

Try this:

 

   (vla-ObjectIdtoObject
     (vla-get-ActiveDocument
       (vlax-get-acad-object))
         (vla-get-OwnerId Obj))

Thanks! Ahh I knew it was that easy.

Also, if using nentselp to get the nested item, look at the last element in the list, after the transformation matrix :wink:

[SteveK]

I don't get that bit of nentselp; I use nentsel heaps, but have yet the need to use nentselp with a predetermined point, and when I try it anyway it just returns a similar output to nentsel, ie no matrix. (which is fine at the moment cause I've yet to find a need for it)

You use it a hell of a lot in GrRead loops :wink: -- it will only return the transformation matrix on nested objects :wink:

Yeah I learnt a lot from your usage of grread in Inc Num Suite - until I went through it I always thought you just got the text to attach itself to the crosshairs somehow.

 

Ahh I see the matrix now. I was only clicking attributes!

Hehe, glad I could be of service to your learning
