you are a beginner right? ^^ if you are holding control while you rotate a object. it can snap in 15 degree.
load an old house from other people made. and have a look for it. than you can see, what you can edit.

thanks so much ive tried it out and it works ill make another one in a couple of days. oh and im not that much of a begginer

Hmmm...
Well, you certainly have patience. That's a good virtue for anyone building stuff in Phun. Still, if you want breakable, stiff connections, I'm afraid Phun doesn't have a 'strength' thingy for fixate, so try putting very small chains between blocks and weakening the hinges. Make sure to have as small gaps as possible though, or your house will bend a lot. As an added bonus, when it does break, you should have some extra shrapnel in there. Yay!

Whoops, I forgot. That method doesn't work. I tried it some time ago, but for some reason I remember setting it up more than actually testing it. I forgot that it sucked.
Lol...

Just put two hinges in, not one.
