Set attribute tags to blank blocks

Hi everyone,

 

I have a library containing various dwg files, which themselves contain one block. All these blocks have no attributes. 

 

Is it possible to create a lisp routine that allows me to select a block and set attribute tags defined in advance in a list? (list "WEIGHT" "ELEMENT_CATEGORY" ""....).

 

The values will be written by hand but if i can avoid setting attribute tags manually it would be great.

 

Thank you for your answers or suggestion, i am aware of any ideas.

 

Have a nice day.

@pierre_costeS8GW8  hi,

 

check this ADDTAGS command.

 

Note:

adding attributes to a block with such command could be messy cause we need to specify the tag position, tag height and other properties. have you thought what would would happen if the block already have attributes?

what if the added attribute will overlap?  does the size will appropriate? some question have to be answer here  😀

 

for start what i did is define some constant variables for you to set:

 

line 15: (setq TAGSCL 1) ; this set the tag\text scale. if it comes small, increase this value.
line 16: (setq TAGHGT 0.25) ; this set the tag\text base height. change it if needed
line 17: (setq DATATAGS '("WEIGHT" "ELEMENT_CATEGORY")) ; define the attributes to add

 

if you select a block that already contain one of DATATAGS tag, the attributes is skipped.

attributes will be positioned from 0,0,0 and above. will it be overlapped? could be, that on you 😀

 

enjoy

Moshe

Hi,

 

First, Thank you very much for your time and your very clear answer.

 

It's 100% sure that my blocks have no attributes. I don't care about their positioning or size because i don't have tested your code but i will try to set them as invisible state.

 

I will try the code.

@pierre_costeS8GW8 

 

Glade to see you find it working, it is a little inefficient version so i will send you an update tonight

i will set them to be invisible plus if you have other requests like text style, font file, justification.... shoot now 😀

 

have a nice day

Moshe

If you could show me how to set them in invisible state it would be incredible.
Thank you so much.

here it is

 

 

change this:

(setq AcDbAttdef (vla-addAttribute AcDbBlkTblRec hgt acAttributeModeLockPosition (strcase tag t)
			  					 (vlax-3d-point (list 0.0 ypos 0.0)) tag (strcase tag t)))

 

to this:

(setq AcDbAttdef (vla-addAttribute AcDbBlkTblRec hgt acAttributeModeLockPosition+acAttributeModeInvisible (strcase tag t) (vlax-3d-point (list 0.0 ypos 0.0)) tag (strcase tag t)))

you reset (all) DATATAGS? why is that?

 

do me a faviour, correct this code line to be 😀

 

(setq AcDbAttdef (vla-addAttribute AcDbBlkTblRec hgt acAttributeModeLockPosition+acAttributeModeInvisible (strcase tag t) (vlax-3d-point (list 0.0 ypos 0.0)) tag (strcase tag t)))

I just clear the list DATATAGS for those who might want to set their own attribute tags

Thank you so much for this @Moshe-A. I have made minor tweaks and its been speeding things up for a few months now.  I wonder if you would mind making a tweak that is a bit beyond me?  Could it be made to delete any attribute definitions that do not show up in DATATAGS and any attributes that are in both DATATAGS and TAGLST (att's in the exist block) get put in the order they show in DATATAGS?
