I own Sonar X3 Producer which includes already Dimension Pro and Rapture.
Is there already a good way to Emulate a Rpck or Metal guitar via a Synth or better a Sampler?
I know that Dimension Pro already has some Rock-Guitar Patches but how can i emulate palm muting?

That's a toughie and the reason why guitarists are a loooong way off from being replaced by softsynths unlike other things like drums and bass.
 
The most realistic sounding guitar synth in Sonar X3 is the AAS Strum thing which is mostly an acoustic sound AFAIK but maybe you could try that and run it through TH2 to see what happens. I don't think you're really gonna get a really good "djent" sound out of anything in Sonar though. Maybe there are third party applications dedicated to metal guit.
 
Good news is us guitarists are a dime a dozen so it'd probably be a lot easier to just ask someone to do it for you. Just compose it with one of the synths and get them to duplicate it.

Feed the dim-pro through a gate with a short hold/release time to chop off the end of the notes, turn down the high frequencies.

That said you may be able to mimic the "djent" sound with some fancy EQ, Compression and or gating. Like let the attack be semi wide open with a quick level and high frequency decay. Sounds like a total pain to set up though but would be an interesting experiment.

Ha! Nice.

IMO, Trying to emulate a guitar can be more tedious than actually learning to play one.   
 
Consider getting a guitar and start by playing/recording simple things in short bits.
As you get better, you'll be able to play more consistent and more complicated parts.
Otherwise, I'd take Beep's advice and collaborate with a real guitar player.
 
 
 

+1-- Being mainly a guitar player, that's been my approach to keyboards and drums. I just started playing them and over time I've gotten good enough to make music in real time,,, I hate the idea of "constructing music... to me that's not enjoyable and can never sound like real music...then use Sonars tools to make me sound even better. 
 

I think it's important to find a balance between afforded capability and not letting things get overly complicated/tedious.
 
Technology can be a great enabler... or it can be a great stifle(r)
 
I enjoy the challenge of tedious things (ie: creating sample libraries where I'm trying to write scripts - not having a programmer's background)... but too much tediousness and (for me) the process is no longer enjoyable.
I'm a terrible guitar player (limited ability), but at this point in my life, I'd rather spend my time trying to play an actual guitar... than to try and simulate playing one.  The process is more enjoyable/rewarding... and my guitar playing is the best it's ever been.  

One thing when planning a guitar emulation with synths is to remember and accept that you're faking.
Don't expect to get realistic and impressive sounds, settle with somewhat impressive and very usable.  Pick a decent guitar sound, even a dry one, from some synth, and start playing with amp simulators and FX. Don't put it too much on the top, because it's weaknesses are then too audible. When the part sounds at its worst, hide it a little into the accompaniment or distract the listener with a cymbal or something, and push the best parts gently forefront.

Almost anything that goes through the Overloud TH2 effect sounds like a rock guitar IMHO. Find the right guitar patch and off you go. As far as performance is concerned, well that's another matter :). I tend to wear a wig when playing...
