Hi Sharif, also you asked:

So if you want to draw it directly in place then a cplane would be what you want for that.

Maybe you could try to show me a file where you are having a problem setting the cplane so I could give you some tips on it, but by default when you locate the cplane on a point on a freeform curve it should get aligned to the curve tangent automatically.

Another option is to draw the curve initially on a world plane, and then use the Transform > Orient command to relocate it to a plane normal to the curve tangent.

There are 4 steps to the orient command, you first pick a starting base point, and then the second pick is to adjust the base axis rotation or you will probably just right-click for the second step to accept the current default rotation. Then you do 2 more similar steps for placing the target location. It looks like this (note there are 2 right clicks happening here as well):
