Block's name to FIELD (ba

tomjas · 发表于 2022-7-5 20:17:43

Hi there,

Another idea

Can anybody help me to modify existing lisp (by Lee Mac- lisp is great, thank you), please?
Right now lisp is creating text field with area value of selected hatch...

I would like to modify it so user can create 'label'=field with name value of selected block (dynamic and not dynamic). I was trying to change this code, but once again without success...

Lisp attached.

Thank you in advance.

Cheers,
Tom

So you want user to select a block and the field to display the block name? Is this at all related to the hatch?

tomjas · 发表于 2022-7-5 20:24:30

Hi Lee Mac,

That was a quick replay

No is not related to the hatch, BUT. Before I managed to modify it so instead of hatch it was creating label with length value of selected pline...
I thought this will be similar as instead of referring to AcDbHatch Area- this will refer to something like AcDbBlock Name (I don't even know how to refer to blocks). I've tried that but is not working...

I have massive collection of blocks and I would like to create a 'label' next to each single one with name of the block... All blocks are in one cad file, that's why I need to see which block is which...
Of course there is no need to ask user about conversion factor or unit type here, only text height and pick block and pick point to create 'label=field'.

I'll really appreciate if you can help me!

Regards,
Tom

Try this:

I’m going to be honest with you Lee. You are GREAT!

  I have no idea how you are doing this, but this is absolutely fantastic!

  Thanks a lot again!
  Cheers,
  Tom

tomjas · 发表于 2022-7-5 20:36:20

I have a question. I’ve tried to understand your code...

I can’t see where you are referring to block (for picking object id). Before you were using AcDbHatch (for hatch id) but I can’t see this one now... Is it working for any object now and then depends what value you want to show, you are changing (i.e):

copy

(LM:GetObjectID doc (vlax-ename->vla-object e)) ">%).EffectiveName>%"

?

Please see screenshots below.

So my question is: if I would like to modify it so want to create label with coordinates of selected point, do I have to change only .EffectiveName to .Coordinates?

Sorry for problems, but I want to understand it rather than bother you every single time

Thanks a lot!

Lee Mac · 发表于 2022-7-5 20:39:34

Correct, you would just change the property that the field is pointing to. I check that the object is a block in the test statement for the WHILE function

tomjas · 发表于 2022-7-5 20:39:59

And is working

I've changed

copy

(eq "[color=Red][b]INSERT[/b][/color]" (cdr (assoc 0 (entget x))))

to

copy

(eq "[color=Red]POINT[/color]" (cdr (assoc 0 (entget x))))

and EffectiveName to Coordinates and is creating label with coordinates of selected point

Now...

as you know there are some 'parameters' in
AcObjProp Object(%%).coordinates \f "%lu2%pr1">%

responsible for units, precision and other stuff...

Is there any way (and by any way I mean simply to understand, edit, change for other type i.e. from %pr to %tu)
to add some options for user to sett, as you did for lisp about hatches on top of this post.
I've tried to copy some code to this lisp to ask user to declare units and precision... of course without success.

So as you did with this code- I was able to understand most of it and change it so is picking different object and returning different value...

So let say for point coordinates, I want user to declare units and precision, so %lu and %pr but later I'll create other lisp (copy) and ask user to declare suffix %ps for length value of selected pline. I would like to know what to change and where (do I have to declare different variable for different stuff?) to be able to do that.

Would it be possible to add this option to code, please?

I've done some programming in c++ years ago on uni, but I can't remember much. But at least I can understand some of your code instead of asking you every single time for new stuff.

Sorry for all those problems, but it's great to learn something from you!

Lee Mac · 发表于 2022-7-5 20:45:18

Certainly, I'm happy that you are willing learn from the code, rather than use it blindly.

I'll post a generic example in a bit

I have included quite a few 'adjustments' at the top of the code - obviously this doesn't include them all, but I wanted to give an idea..

Most error trapping regarding using the correct field code values is left to the user.
