Trouble to get precise measurements in 3D space!

I have reall trouble to draw lines and splines with precise measures in moi 3d. I somehow cant get a grip on which plane I am or what dimension ...
I am normally not all thumbs. ... but this 3D space aligning is just to much I think ...

So my question is will there be an oldschool draw on one plane and make dimensioning on that plane and then exit it (like Solidworks , Pro/E) kinda way some day?

By the way the export to cinema with N-Gons is the best I've seen so far .... I 'll just consider buying Moi3d solley for this purpose ...

ps. I am currently moddeling in Solidworks (yes surfaces heavy stuff) and render in Cinema 4D
