I want to make a template for this model.
How can I do that?
You need to explain what you want.
Asking about a template here is generally how to set up the model space.
You are obviously after something else but its not clear what.
And note the Tutorial category is for actual tutorials and there is a separte sub category for requests, which your last two threads have been moved to.
Goto menu File > Save as template
I want to make a mold and convert to g-code and make the mold with cnc
No how to make a plastic mold injection
Sorry for that because I translate it in Google Translate
Can you tell me to how do that ?
You can make a solid block group as the die and a copy of your object as a pattern. Then use Subtract from the Solid Tools to subtract the pattern from the die.

Nice bro thanks
