* \brief Basic 2D drawing tools and other generic tools
The Draft workbench provides many tools for building geometrical
objects in a two-dimensional space, normally supported by a working plane
that includes a grid.
The grid serves as visual feedback of the coordinates and dimensions
of the geometrical elements that are created. Moreover, the vertices
of the elements can be attached to the grid intersections to precisely
position them in the plane.
The Draft workbench also includes many "Modifier" tools that can be used
by most objects in the software because these tools work on the internal
Part::TopoShape property that most 2D and 3D objects have.
The Draft workbench is similar to the Sketcher workbench in that both
can be used to create 2D objects in a planar surface. However, there is
an important difference:
- The Sketcher defines a local coordinate system; all geometrical elements
created within it are referenced to this local origin. In addition,
the position of those elements, as well as various relationships,
are kept through the use of mathematical constraints (vertical, horizontal,
parallelism, etc.).
- On the other hand, the elements created with Draft are placed in the global
coordinate system. The elements in Draft don't have constraints, they are
freely placed in the 3D space.
The Sketcher Workbench is intended to be used together with the Part
and PartDesign workbenches to create very fine profiles that can be extruded
to create complex 3D solids.
The Draft Workbench is more intended to draw exclusively in a 2D plane
placing points in a grid. Often this behavior is better suited for
drawing architectural plans, or for quick "drafting" that doesn't need
to keep mathematical constraints between its elements.
Due to this reason, the Draft Workbench is the foundation on which
the Arch Workbench sits. All tools of the Draft Workbench are available
in the Arch Workbench.
