Wire Types Missing - But not the layers

[drathak]

I had just added several wire types in my drawing, then added a wire or two.  Then changed an existing wire to another type.  Went back to the Create/Edit Wire Type dialog and now I see no wire types.  The layers still exist in the layers pallette though.

Any ideas on what could have cause this and/or how to fix it?

Do you think you might have clicked "cancel" by mistake?

I have done that myself a few times...

No, because even the previously existing wire types are gone.  And like I said, the layers were created.

I'm not sure what caused this, but the information about what layers that are "wire layers" is stored in the invisible WD_M block, in the attribute WIRELAYS (Use the attdisp command to make the attributes visible).

What does this attribute say?

To FIX this, you can use

a) IN the create/edit wire types dialog, press "Add Existing Layer.."

b) If the layers are correct in one drawing you have and you are running AcadE 2011 or later, use the Import Wire Types function in the Project Utilities dialog.
