Topic: Entity Locking, How to?

[Jim Yadon]

I have a challenge for you folks. I would have no idea how to do it myself so I wouldn't even know where to start.

Here are the criteria-

• Lock a single entity.
• The layer itself cannot be locked. You have to have freedom to modify anything else on that layer.
• Nothing about the object can be changed. Not a single attribute or property.
• It has to work with any geometry (including text) in AutoCAD

Kinda hard to lock an entity without being able to modify the entity. Please clarify, as even an object reactor may modify an entity.

I posted here the routine KEEP... it does basically what you want, do a search and if you can't find it, I'll posted here again.

Go to http://www.waun.org/
Post the request to Peter for the routine.

Works great.

Locking the layer is easy. i wrote one of those my self. I'm looking at locking only a single entity of any type. Locking all attributes or properties.

I guess you could get the atoms family for all the vlax-properties, and then test those to see which ones will apply to that object, and then make an associated list of the properties and the values.  Then set up a reactor for that object, and when anything is changed, change it back.

Those were great examples of locking it into the drawing but I still don't understand the logic enough (or maybe I'm missing something all together) to see how it would prevent the change of any properties or attributes of an object.

Jay;

Have a look also on the samples I uploaded about reactorswiz... on the show your stuff, in them I added some functions to lock the attributes heights, location, layer, etc...

I am busy right now with a dead line, I'll be back... to see if I can help...

Cheers...
