Split a dynamic block into a single block for each state

[woodman78]

I am looking to split a dynamic block with visibility states into a series of blocks with a block for each visibility state. Can anyone help with this?

[samifox]

you can use Lee's lisp to rename viability state as a new block quickly,

some clean up should be done later on

[pBe]

Its quite easy. This would be fun to code

 

Grab all Visibility names via GetDynamicBlockProperties

 

Create one block for each via ConvertToStaticBlock

 

Did i not say its easy and fun to code?

No, I don't think you did.

[woodman78]

Anyone care to give it a shot?

[samifox]

No, I don't think you did.

 

im afraid we didnt got the joke:cry:

[woodman78]

Thanks guys I already use Lee's RB command but does anyone have a way to make a block static on a certain visibility state?

Have you tried the CB option in Lee's lisp, from the description, it sounds like it may be able to do it?

[woodman78]

Thanks for your help guys that Lee's lisp doesn't make the static block. Any other ideas?

[woodman78]

Thanks guys. I found this link from a LeeMac reply:

When in doubt, check Lee Mac out.

Many thanks for all the recommendations guys

 

It was indeed quite fun to code - here's a quick draft:

Brilliant as usual LeeMac. Stunning stuff. It is exactly what I was after even down to the naming of the blocks. Thanks.

[Lee Mac]

Thank you woodman, it was an interesting one to write - I'm glad you are pleased with the result

[pBe]

Yup. indeed its.

[chico1201]

Thanks for your help the lisp doesn't displayed in an AutoCAD Table. Any other ideas?

[hagra]

The lisp stops at 8 visibility states and stops running. What have I missed? there are about 20 states in the block

[gozzix85]

Anyone has a way to keep each block's dynamic properties? Should be an easy fix to the code above. Thanks
