Mate 2 mesh items

Rhino Rhino for Windows

i imported some stl files (parts) and i would like to put them together to make an assembly. what command would use to mate/lineup the 2 parts and would they be constrained or is that a separate command?

Without a specific example file, it will be impossible to guess what needs to be done.

Thanks

Hi David - most likely Orient3Pt with some careful snapping to mesh vertices. Best to post a simple example file. Constraining is a differfent question - depends what that means in this context - you can Join or Group the meshes however.

thanks, sorry for the vague question. I try to get the align or the orient to mate but i haven’t got the hang of yet. here is an example, i can’t mate the cylinder on top of the box.

Hi David - here the objects’ faces to be mated are aligned so plain old Move will do it = point to move from is the center of the bottom face of the box (Between osnap with snaps to opposite corners) , say, and point to move to is the center of the top face of the cylinder (Cen OSnap) . There are other ways - for example an OnSrf snap at each end of the Move operation.
Note there is no such thing as a mate in Rhino - you’ll just get the objects located in a matey kind of way.

thanks that will give me something to work with.
