Dear Max98t,
The PASTECLIP command inserts the AutoCAD objects in clipboard as simple objects. To insert as a block you should use the PASTEBLOCK command. To change the default settings for inserting as block, follow the bellow instructions:
1- Append the following expression in a separate line at the end of file acaddoc.lsp in the "support" folder of AutoCAD. If there is no file named acaddoc.lsp, you can create it using Notepad.
2- Open the file acad.pgp and add the following line to define an alias for the command PASTECLIP.
PASTECLIP, *PASTEBLOCK
3- Run AutoCAD, and everything will be OK. The "Ctrl+V" shortcut key and also the relevant button in the "Standard" toolbar will run the PASTEBLOCK instead of PASTECLIP.
