Snap to point cloud and Point cloud Color

Hi there. I’m new to the community and to blender.
I have a question for you. How i make a curve create it point to point (cvs maya user) and snap the cvs to Point cloud and how topology a point cloud. I need the point cloud in viewport not create a mesh and snap to it.
Really sorry for this newbie question but really i dont able to find the answer.
I have also another question, is possible to see the point cloud color in viewport? i don’t need to render it, only see in viewport.
P.S. Point cloud from ply


Thank you very much for the answer/help. Also is there a way to modelling from point cloud in blender? Something like modelling curve snappping on point cloud and extrude, loft or something like that?
Is there a tutorial?
