It would be better to have Translational repeat for inclined planes too in addition to X/Y/Z with reference plane or nodes. It is good for adding members or frames from inclined plane to same inclination plane
That capability is available in the Physical Model workflow. Simply create a UCS that defines the plane that you wish to generate the model and then when using the Translational Repeat, then choose that as your coordinate system.
