Hiding/Unlocking Layers (including Block)

k005 — Sat, 18 May 2024 19:33:21 GMT

Hello friends;

We can hide the layer with the LAYOFF command. However, in case of Block, this does not work. I use the LAYFRZ command instead.

What I want to do is to use layoff if the selected object layer is block and not layfrz.,..

example command name: defun C:LayhidView . If it is closed, it can be opened with a single command. If it is open, close it...

Thanks in advance to the helpful friend.

LAYOFF just like LAYFRZ should be able to turn off objects inside blocks.

Make sure you select Settings > Block selection > Block is selected

I asked for a routine that turns it on/off with the same command. Thank you.

From what I'm understanding by reading your OP, LayOff & LayFrz both do let you pick an object even inside a Block to turn off or freeze. But if you want to pick an object to turn back on inside a Block that would not be possible since you cannot see an object that is turned off or frozen. Please clarify your request.

No . We will not select anything to open. It will open all closed layers or frozen ones... the choice will be only when closing.

Download my free LayerApps that includes two new commands called DDLyrOn and DDLyrTh that will show all Off or Frozen layers in a dialog box for you to select from to turn On or Thaw

To thaw and turn on a Layer that's frozen or off, I have a routine that does it for top-level objects but not nested ones [LayerThawOnSelect.lsp, >here<]. But I don't understand how you would use a single command to either do that or turn the Layer off. Thawing/turning-on requires turning everything on temporarily so that you can pick something on a Layer you want on. But surely if your intent is sometimes to turn off the Layer of something, you don't need everything turned on -- the Layer you want to turn off is already available for the picking.

So you invoke the command you're looking for, and everything comes on [because it must if you're going for turning something on that's currently off] and then you pick something. How do you imagine the command would be able to know whether that's on a Layer you want on or off?

I think this way:

Open: If there is any closed or frozen layer in the layer list, open it. Otherwise, do not take any action and exit...

Closing: If the selected layer is a block, freeze it. If not, close the layer.
