Lisp Routine to change Blocks Line Type

Irreb — Fri, 16 Apr 2021 18:56:29 GMT

Hi Everyone, i recently found online (i guess) the most useful LISP Routine ever.

This one allows to change the color of selected blocks to a specific color from 1 to 255 or ByLayer or ByBlock, for all objects inside the block regardless of weather it is a static or dynamic block.

(I have attached it to this post)

All i want to ask is this:

as i don't know how to write these LISP routines myself, can anyone help me modify this attached LISP so it does a very similar job with line type instead?
what i need it to do is:
- changing the line type to a specific one i chose or ByLayer or ByBlock
- change the scale of the new line type

one cool thing that would make it very good is if it can get the line type and scale data from a selected object and apply it to one or more selected blocks.

You can also try CHZ20.

It can change the block subentities' linetype to ByLayer or ByBlock, also change the Linetype Scale etc.

Thanks for the software.
Although the software is free it appears it need a "free" subscription for one year, after which you have to subscribe to something else etc etc.

I trust you that this program works, though i much prefer something from the community and free and that can be modified easily if necessary (just like the lisp routine i shared)

thanks for the advice anyways

This should do the thing. Possibly you can comment in/out other properties -- see the semicolons.

Hi,

thanks for the routine. not sure it is working..or maybe i am not doing it correctly.

I loaded the lisp and run the command:

-> "BFIXLT+S"

-> select the block reference

-> hit enter

-> select the line of reference with the the line type and scale i am looing for

-> the model regenerate automatically and nothing has changed..

am i doing something wrong?

edit:
only the line scale has changed, line type stays the same as the original.

Yeah, I can imagine. It takes object properties, not layer properties.

I don't think i understand your answer.
Maybe i didn't explain properly what i am looking for.

what I would like is something that works like this:

-> insert command in command line

-> select the line or other object which has the line type and scale i want to match the block reference to

-> hit enter

-> select one or more block references of which i want to change all line type and scales of all objects in it

-> done

basically the "MATCHPROP" command, but that works toward any block reference instead of single elements.
