Yes. Insert the views in the drawing and set the sketches to show in drawing.
Just ran some tests.
a. I can sketch on a drawing just like I can in the 3D window
b. I can copy a sketch from 3D paste it into a drawing then manipulate it
I cannot create a drawing of a sketch done from a 3d window unless that window has a solid component in it.
I created a dummy solid feature in the 3d window containing the sketch which then allowed me to create a drawing.
1. I could not figure out how to turn on the sketch imported from the 3d window.
2. I apparently cannot create a drawing without having a 3d object.
Your terminology is a little inconsistent with what is typically used in a 3D modeling environment. That is probably where some of the confusion is occuring.
Regarding your issue. You can create a model (.sldprt) with all of your sketches in it. You can then create a drawing (.slddrw) of that sketch. You will have to do as Deepak mentioned and turn on sketches in the drawing. Do this by going to view>sketches from within the drawing file.
You can definitely create a drawing of a model that has only sketches in it. I just tried.
oh hell yes you can!!!! in a part file, make the sketch you want, close the sketch, select the scetch from the tree, control c, open a drawing, cancel the part import, then control v and wahla your sketch is there.
but here is my question to you WHY, it's so much faster to do a solid than a complicated sketch? but too each his own, use the power of windows copy and paste, you just get more control over your sketching in the part file over trying to do the same thing in the drawing file.
