Selecting Nested attribute text enity to remove hatch over it

October 21, 2013

Hi all,

I need help on selecting a nested object which is attributed text from the block to be able to remove hatch over it. Below is the code that I'm using currently (not mine originaly, I tweaked it a bit for my application). This code just works for the whole block but doesnt allow me to select just the text.

 
(defun Fixhatch (/ Hatchfix objct)
(while
     (setq Hatchfix (entsel "\nSelect Hatch to fix (or Enter to close):"))
            (redraw (car Hatchfix) 3)
            (Alert "\n***Select object(s) to clear/skip hatch:***")
     (setq objct (ssget))
        
     (if (eq (cdr (assoc 0 (entget (setq Hatchfix (car Hatchfix))))) "HATCH")
    
     (command "_.-hatchedit" Hatchfix "Ad" "s" objct "" "")
  (princ "\nSelected entity is not a hatch.")
      );end if
);end while
     
);end defun

As you can see the text TB6 is an attribute text of the rectangle block and I want to remove hatch just from the text.

Can this be done?

Thanks in advance.

As far as I know, even if the attribute subentity is supplied to the HATCHEDIT command (using an nentsel selection), the command will only process the primary block reference entity, hence creating the hatch boundary around the block.

Hi Tharwat,

I tried using your code but it just deletes the hatch. This is not how I intended. May be I did not explain it well.

Below image shows my lisp does the "INCORRECT" version. If somehow I could get the "CORRECT" version so that the hatch skips the attribute text only (not the whole block).

I see what Lee is saying using nentsel but limited to only select the upper level entity (which is block).

Is there a way around this?

October 22, 2013

Is the hatch part of the block? or a separate entity?

Hatch is a separate entity. And its added by a lisp utility which adds hatch to multiple clouding in one go.

Here's how i would approach the problem:

Select the attribute entity

Copy selected nested entity

Create a TEXT matching the ATTRIBUTE properties

Run your FIXHATCH thingy

Remove associative property of hatch

Delete copied TEXT string

EDIT: YES in one go.

Thanks pBe for your suggestion.

But this is exactly what I have been doing as a work around so far. But then it requires more work to be done.

I was thinking AutoLISP may have a different method to tackle this. Also, the remove hatching is not just limited to text only. Sometimes, I have to select other-than-text entities as well from the block.

Well, not really shailujp, Hang on i'll write a short code for ATTRIBUTES...

I'm must commend both of you (Lee & pBe). Great stuff. Now, I have to find a way to incorporate it in my master lisp.

Just one more thing. What if I have a large area with multiple attributes to select to clear hatch?

Other than the attribute text, is it too much to ask if I have only text inside a block to be holed in hatch (not the attribute). Can this work for both?

(Sorry to alter the path but things started to click once I saw this happening).

Thank you shailujp. Yes it can be done, Lets wait for LM to modify the code he posted, It's more complete than the one i wrote

I'm pretty sure its easy

Hi Lee,

Could you please help me on this?

Lee's superior coding has made him a busy man, but I would wager he will get back to this in due time. Sorry, he's just helped me with a completely separate issue on another forum. It's downright amazing, frankly, to keep all the codes separate but accurate regardless...

Code modified to work on either TEXT or ATTRIBUTE, also for selected entity types [CIRCLE, LINE, LWPOLYLINE]

ps. Yes, also MULTIPLE selection

Nice work pBe. Works perfectly fine for attribute texts. Just few minor hick-ups for other type of text. I have attached the .dwg file so that you can see what happens. Cyan color text are plain text outside of block. Top block is attribute block so no issues with that. Other remaining entities are text but inside a block (BANNER, LT OP, BN, NU WH etc.).

1) When I click on Cyan plain text (not inside block), it gives me error bad transformation matrix and terminates. Also it creates a copy of the text but since programm terminates, it leave the 2nd copy and doesnt get erased.

2) Text within blocks do not seem to be selected (although they are). This is display thing which make me doubt whether or not they are really selected. Can anything be done.

3) Did you also attempt to add other type of entities (circle, ellipse, arc, lines)? It seems that it also gives me bad transformation matrix error and creates a duplicate copy of it.

....Cyan color text are plain text outside of block.....

*** I wasn't counting on entities outside the block. but i have an idea how to distinguish the selected enity. i'll work on this later.

Hi pBe, I tried your updated code. It highlights hatch and then for attribute text since it creates a temporary duplicate text, it make me sure about a valid selection. The only issue is with the text which are in the block but not attributes. They dont seem to get highlighted since they dont create a ghost.

Did this work for you?

Clarification regarding other types of entities (lines/arc/circles etc...): I do not want to select other types of objects. This utility is needed only for text objects. For the other objects, my utility works fine and I do not want to combine two. I had to scratch my head a bit on how I want to use this but finally I'm clear.

And please take your time....I can definately wait.

Hi pBe,

Have you had time to resolve last few hurdles on this routine?
