Using multiple visibility parameters in a dynamic block

[mehdi-guida]

Hi

Is there any way to use multiple visibility parameters in a dynamic block by Lisp routine(without using lookup)?

[j.palmeL29YX]

No. 

(AutoCAD doesn't allow more than one Vis. Parameter. This limitation cannot be overcome even with Lisp).

Thank You for reply.

I remembered previous posts.

But I've heard about some routines and hope someone can give me more information.

There are certainly several ways to control the visibility of objects within a dynamic block, including via LISP.

But you asked explicitely how "to use multiple visibility parameters". And as long as a block definition can include only one visibility parameter at a time you never can use multiple of them. 

Perhaps you should describe more detailed what you want to achieve ... mybe we find a solution. 

[mehdi-guida]

you are right, I meant finding any possible way to use visibility parameter more than one time in a dynamic block.

I've heard some it is possible by lisp routines and downloaded some of them, but I couldn't work with them.

Cheat using double lookups. See the pinned topic about them

He knows this way (>>click<<)  but for some reason @mehdi-guida doesn't want to or can't take this suggestion. [cit from post #1: "Is there any way ... (without using lookup)?"]

How does this work. I can't figure it out. looks like it has 3

That block was created using the Visibility-Add-Eng LISP routine that has not worked for any version of AutoCAD since ~2010.  My understanding is that it exploited a flaw in the code that has consequently been patched and there is not a way to make that LISP routine work with any later versions.

Thank you again 

[mike_collinsAA9YL]

Thank you.   Could I install that version of acad to do this again 

[Libbya]

Yes, you can and as far as I know the blocks will still work with later versions of AutoCAD.  That said, I've used it and IMO it is not worth doing.  The Visibility-Add-Eng was glitchy, unintuitive and editing existing blocks that were created using it was an absolute pita.  For simple blocks it could work, but in that case I definitely prefer using the double lookup method which is easier to use, and much easier to edit later on with changes.

does anyone have this lisp?

After less than 1 min searching in the web I found this:

If the change in visibility state is a simple matter of changing text values, you could try using formulas for text values that will look at a table reference within the block.  Or if it's as simple as a number change, a formula which looks at the value of a block attribute.  You can change the block attribute per block.
