Summary0000014: Sketch object
DescriptionAn object which is dedicated to 2D CAD data.
Its derived from Part object and have additional like a
grid in the view. The local koordinates set up a plane where the 2D data
live in the 3D space.
TagsNo tags attached.

I think a grid is a very good idea, but are you sure it is necessary to
have a second coordinate set? I think 2D data are, in an app like FreeCAD,
just there as a starter point for building 3D from it, right? So, 2D shapes
should be freely moveable and "drawable" in the 3D space...

Or are you thinking of a kind of "temporary workplane" that follows you?
This would be cool... like, for example, your mouse is on top of an
existing face, and the work plane becomes the face. This would make many
operations easier... 2D works should only care about 2D coordinates, and
FreeCAD would place all this in the 3D space nicely.

Other interesting thing, that workplane could have cool helpers, like a
grid, but also things like alignment axis, etc...

I am thinking that such a workplane could be an easier space for
experimenting with constrain solving too.

One thing I wonder: would all 2D data belong to such an object? Or maybe
it should be considered a helper, only present when you draw. Because a
very interesting thing, in my opinion, is that everything you draw with
Part objects, is already 3D-ready... Once you draw shapes, you only need to
extrude and you have 3d solids. This is very easy...
