My quick answer is yes. Could you post an example of what your looking for?
To the best of my knowledge NX does not have a "Plasma" or " Laser" cutting operation.
I have see people use Planar Mill and Wire - EDM operations to create a tool path for this and other 2 axis cutting equipment. The truly important thing will be a post processor to format the NC code.
My question are : What should I do so that laser template can be used? - Contact GTAC
Is it the similar between plasma cutting with laser cutting program? - Without an example of what the NC code looks like it would not be possible for me to answer.
If you have an example of he NC code your looking to create then post it here.
The Laser Template you see was an early attempt by Siemens in developing 5 axis laser functionality. It never even made it to the preview stage.
For plasma cutting ( I am assumimng 2 1/2 axis ), I would start by using planar profile operations and letting the post with some custom UDEs to controll all specific commands.
