Are these normal XYZ points, more or less?
Do you mean how to draw them in the Revit model?
I assume that you have exactly two options:
- In a planar view: using detail lines
- In a 3D view: using model lines
You can check out The Building Coder samples Creator class:

Maybe it does more or less what you need.
