Multiple Visibility

[tj6TCQ5]

I know this has been asked and answered but the only potential solutions (videos) have since been removed or are no longer authenticated. I am seeking to learn how to make a few objects be turned on and off within an existing dynamic block that already has visibilities for other objects within the block. Specifically I would like a video showing how to use the linear parameter with the scale action and a lookup to be able to turn the objects on and off. Each post I've found regarding this simply links their example block or the video shows many additional functions that are drawn concurrently and muddy up what I am trying to learn. 

A clear example would be to draw just the flag and circle portion of the weld symbol and turn off one or the other without using a visibility. I have tried to mimic the videos and/or use someone else's existing block to figure out how it was done but some of the actions and parameters that are created only have specific options available when they are created.

It would be greatly appreciated if someone could provide this video. Thank you.

POST THE BLOCK.

What you are describing doesn't actually turn an object off/on.  It scales it down so small that it becomes a dot.  Depending on the number of visibility states you already have, how the block is set up, and how you want it to behave that might be desirable or it might not.  

Anyway, here is the scaling method.

Thank you very much. I already understood everything you explained but what was never shown and is impossible to see after the block is created is the 0.001" part as Autocad only shows 0". I haven't programmed in years but that should have clicked for me much earlier.

Again, Thank You.
