Layer Locking

[Maurice.148748]

Hi,
Is there any way a layer can be locked so that nothing can be erased or drawn on that layer?
thanks for your help.

Well you can lock a layer so that nothing can be erased but you can still select the layer as current and draw entities on that layer.

What are you trying to do? You may want to look at creating blocks or inserting x-refs instead.

Hi,
Thanks for the reply. Personally, I would go down the xref route, but my client - for his own good reasons - wants one drawing containing all the elements and is looking for a way to protect certain layers against accidental modification.

I not surprised there is not facility for this. It seems users would like a secure layer locking feature (particularly the 'smaller' user) but its not high enough on any wish list.

Thanks for your help.

Look into using either Object, or Editor Reactors (Visual LISP) for this.

You won't be able to stop someone from deleting any objects, but the reactor can copy the entity data, and rebuild the object someone deletes seemingly instantaneously. The user, if unaware that the reactor is being used, will simply see that they cannot delete an object.

Edit:
Similarly, you could have your reactor set such that if any layer in your predefined layer list is unlocked, the reactor would in turn re-lock said layer. Again, seemingly instantaneously. You have several options, despite being unable to use XREFs.

Check out the AutoLISP Programming forum for help.

Well, you could use blocks instead of xrefs - they do much the same thing but are contained within the single DWG. Basically it's like a bound xref.

Hi,
Thanks for all your help, I'll look into the editor reactor option.
