modeling of rays together

[darcy]

good day to all, from some time I've been practicing with modeling of rays for mechanical processes of assemblies, with no result. Could you help me someone or exist some immersed tutorials?

the radius command does not exist in combination mode, as well as others where you add material, you can only remove material and to do so you have to use a cutting sweep.
