If you have a DWG template with a block inside with the same name as the DWG file, and you try to insert it into another DWG file, then you often get the error:

"Block references itself"

To fix this you can on the command line run this command by adding an asterix (*) before the filename with the extension “.dwg”:

Example inserting MyBlock.dwg with a block inside called MyBlock should be specified as below.

-INSERT Enter block name or [?]: *C:\MyFolder\MyBlock

Thereafter, is just specify insertion point, scale etc.

If there already is a block specified inside the current called MyBlock then you will have to purge this block before the above.
