Thank you for your attempt to help, I appreciate this method and recognize it as being suggested above by others. However it seems you may have missed my part about workflow, this is significantly slower than the way I can do it on Illustrator. In order to do it on Illustrator, I click Line Tool, click where I want (can use snapping), then type the length, hit tab, type the angle and enter I'm done. When doing a full blown design piece with 100's if not 1000's of lines based on this workflow, understandably the transform tool is comparatively non-viable. I understand my design workflow is not common as such, but the point others have made stands where the transform method is not a viable solution to their workflow either (I think some say they do CAD like design work in it).
To break it down a bit further, the reason the suggested workflow is not necessarily viable is in the sense that you're doing unnecessary work. Why should one have to create an arbitrary line with one tool, move to another tool, to modify it, and then leverage another section to modify it, and then again start the process of again. It's magnitudes of length longer when scaled out over a typical design. Compared to the simplicity that is one tool (Illustrator) and immediate results, no doubling up of work of having to refine or review the next step.
For now, I have to decide whether I continue investing in Illustrator, or whether I utilize a CAD tool in my workflow.
