Phase Tool?

Hello, im trying to make some figures on garrys mod but I am having some problems making the models hold things as the boundry seems to be further away from the hand. Is there any tool which alows you to make an item go through other items? It would be like phase on halo: Reach. This would alow me to make things quite easy, It would be good if it worked with the physics gun
Thanks for your help.

No-collide tool

You genius…

Is there a way, once you have the object in the place you want, to make it solid again?

If you right clicked, just right click on it again. If you did it with another prop, just click on both of them again
