Stretch hatch boundary to "0"

[cadpoobah]

Since we can't have multiple visibility states in DB's (C'mon, man!), I am using a lookup table as a workaround (a-hem!)

I have a small panel indicating a 2" filler that I will need to show or hide. It has a dot hatch pattern in it. The block will (eventually) have other visibility states, so I can't use one for the show/hide. Instead, I'm attempting to "stretch" the rectangle (the hatch boundary) to a very small width (0.01"), essentially hiding the panel & its hatch pattern. I use a linear parameter (for the stretch) driven by a lookup (with "show" & "hide" options).

The hatch is associative, and will stretch properly, except when it gets that small. The hatch stays the original width (2"). Is there a limit to how "thin" a hatch boundary can be? In this case, I even adjusted the hatch origin so that there was just a row of dots still visible within the thin hatch boundary. No luck.

I left the linear grip on for testing. Once working, I'll turn it off.

Oh, for multiple visibility states......

BTW, this also seems to be effected by the current zoom! It works if you are zoomed in on the panel you are attempting to "hide".

It also doesn't appear to be effected by the type of hatch. I wondered if the Dot pattern was causing part of the issue. I switched it to plain ol' ansi31. No change.

Got Lisp?

Multi-Vis

Take your time, many enjoy this. For an example look here in the DynBlk Sharing for a Weld symbol I posted from the Autodesk DynBlk Forum.

I tried it (v1.5), but haven't had any luck. I've heard & read good things about it.

I get this:

Select point for placing Visibility Set:
> (It places a "Fantom" visibility state which appears for a second, then diappears.)

** Visibility parameter already exists in block definition. **Unknown command
"L". Press F1 for help.
Unknown command "VISIBILITY: 7FFFF0D3". Press F1 for help.

The error code varies. I've seen 7FFFF0AB, 7FFFF08F, etc.

Thoughts?

I am on LT and therefore do not have Lisp so no direct knowledge of how this works.
It may be good for you to post on the Autodesk site and get help from the several who use it there.
Jump the same thread and use it. You will get a response. I've not seen that one sit idle when someone poses a question.

BTW - Did you make it to the end of the thread? There are several version for different versions of CAD. The latest is at the end.
