You have created some sketch blocks or solid bodies in your part file.
You want to create assemblies and parts out of them with the command Make Components, but you want to set some different from the Standard ones default templates for them.
You can change these settings in the Make Components Options dialog accessible from the Part Document Settings, Modeling tab.
From this dialog you can change also other default settings as you can see from the image above and read in more details in the WikiHelp under “Make components options”.
Of course, if you want, you can save these settings in your part template.
