Make component faces always parallel?

[Anonymous]

In Inventor 2016, (in an assembly) how do I make the faces of two or more parts always parallel with one another but without restricting their faces with being always being flush.

To illustrate (see attached pic) say if I wanted the "A" faces of both parts to always face the same direction (parallel with one another) but be able to move the blue box back away from the green box's face (as illustrated)--what is the assembly constraints method for this?  Solid Works has a simple "parallel" feature but it's not so clear in Inventor...  

Currently, I'm having to use a flush solution but then deleting it so that I can move the component's faces away from flush... which I have to be very careful not to sping the component accidentally.

Please help!  This is driving me nuts!

You can give a desired offset in the constraint tool window.

How about a 0 Degree angle constraint?

I would like a way to perform this without pre-setting a distance offset right off.  Any way to do this?

Attach your assembly here and end all doubt.

As Paul stated above.. Use angle constraint.. set to 0 degrees.. Same as being parallel..
