*UXX Block Name

[jkg]

I just ran into a block named *U28. It is not editable. What does this type of naming signify and how did it get created? It was from the OOTB callouts.

Thanks for any help!

The "name" signifies that it is actually an "unnamed" block. Such are usually created by applications, and are often not directly editable. Dynamic block instances are typically unnamed blocks (why?) as hatches in early versions Autocad used to be.

I'm not sure if it's important to what I'm doing but I don't really know. It is actually just one small question in my whole scheme of confusion of trying to figure out how callouts work.

I'm trying to create a custom callout and the OOTB label tag has a pline that is an unnamed block. I wanted to make the line dynamic but I cannot (because it's not named) and when I try to recreate a callout from scratch - the tool and other things seem not to work right - certainly not the way I would like.

Thanks for your help!!! Can you point me in the right direction for some callout and tag block help?

you are wrong when you say the unnamed block is uneditable. They can be edited using the block editor.

and the *U28 appears to be a block created by Eagle Point

Anssi I think I must apologize. I may have to eat some crow here. I done some more checking. some unnamed blocks can be edited and some can't. I believe the ones that can be edited are made by programs that use AutoCAD as a base drafting program such as Eagle Point or Foresight. The ones that can't are made by other programs. the for curve numbers in Eagle Point are similar block name *UXX.

What makes you think that? The numerical portion of an unnamed block name is generated by AutoCAD at the time of the blocks creation.
