Uneditable Attribute Definitions

[cgv]

Hi,

 

I was wondering if there was a way to create an attribute definition in a block that doesn't show up as editable. Sort of like making a read-only attribute definition. Is this possible?

 

Thanks.

In the attribute definition dialog, check the "Constant" check box. This will make the attribute uneditable.

 

Here's a listing of the different options and what they do: http://knowledge.autodesk.com/support/autocad/learn-explore/caas/CloudHelp/cloudhelp/2015/ENU/AutoCAD-Core/files/GUID-92A7CE9D-2E1C-415E-A1BF-5CB35D5E2D38-htm.html

Awesome! Thanks mate.

Another option would be to make it text instead of an attribute. That is unless it is necessary to have it be an attribute.

The problem is, I'm trying to use a field or attribute definition in a block to link to the contents of an already existing attribute definition within the block. So there will be 2 attribute definitions with the same contents within the block. One would act as a halo mask to the other. Bit hard to explain.

Thats another problem, could you post the block to show what you are trying to achieve, but as a general rule attributes donùt like refereing to other attributes within the block, especially if you need to make changes in one and want it to change in the second, for that you need to have a dynamic block and an action that does nothing except act. Again hard to explain.
