Entering numbers - that get projected

http://docs.mcneel.com/rhino/5/help/en-us/index.htm#user_interface/unit_systems.htm

i am an intense user of keyboard input, i do a lot with for example wr0,0,1 to get a world z-Axis while constructing in a custom cplane.

can i somehow force a numeric input / coordinate to get projected ?
being in a custom c-plane i would love to do a (pseudo-code)
wr0,1,0p
would mean: world relative x=0, y=1, z=0 projected to current cplane

any idea without additional construction lines ?
kind regards -tom

Hi Tom - I do not see how to do this in the current scheme of things. A script can find those points of course but not transparently, I don’t think, as you’d need.

Dear Pascal - thanks for having a look at it… i am also satisfied with drawing a line first then snap the endpoint with project turned on… kind regards -tom
