Here in Taiwan "Block" general called as Tu Kuai
"template" called as Yang Pang
If you mens : although"Block"is inserted already, But didn't appear ?
I guess this block is a Drawing frame.and the block size is too big compare
with the current drawing objects.
I suggest :
When you insert the Block(frame), Zoom All or Zoom Extend first.
If the size isn't proper, delete it and reinsert with different X or Y
direction again
