Answer:
If you have a version higher than 6.02.0027, simply right-click on the block(s) you want to delete, then select the “Delete” option in the shortcut menu.
Otherwise, if you are using version 6.02.0027 or earlier, you cannot delete blocks directly from the Dlubal Center.
However, if you enter the wrong input data for a block template, you can delete the template and create a new one.
To do this, go directly to the directory created automatically for the blocks:
C:\Users\User Name\AppData\Local\Dlubal\Dlubal Center\Blocks\user_blocks
