Block Editor and UCS

I can't seem to change the UCS when working in Block Editor. Is this a bug or a severe limitation within the software?

start UCS command and read what ACAD says.. [F2]

So it is designed and not a bug.

BEDIT came with parametric / dynamic Block feature,

dynamic blocks feature is not designed for 3D Blocks, i guess this was the thought to disable UCS.

For non-dynamic blocks, use REFEDIT command

Does refedit change the source block, or just the instances within the current drawing?

I am not sure what you asking for , but

The Story of Blocks

1. A Block is a named object, like a container, without graphical display

2. A Block is saved in your active drawing file. Yo you can have 3 files, all with a block "TEST", but in each file the block looks differently. a line, a circle, just a text.

If you need a central source, use XREF technlogy

3. Inside the block container you can create geometric objects, like a circle

4. Another object type is the block reference, also without graphical display, except you have attributes attached

These "block reference" objects displaying the content of the referenced block container, in my sample the circle.

You can not edit the "content" of a block reference because a block reference have no content.

(Attributes are special and another topic)

Note: REFEDIT is able to edit the source file of DWG Xrefs!

But if you are talking about Blocks.. There is no linked source file, just the block defintion (container) inside the active file.

Thanks for the explanation.

I always assumed refedit was purely for dealing with xrefs, which I have never used.

I shall use it to edit blocks now instead of the block editor.
