I propose to offer the user a input form for coordinates of geometry points. By
this it would be easy to create exact geometry, especially at free form curves
or bezier curves and other relevant points of geometry or help-geometry.

Shape
The input form could either be integrated in the status bar on the bottom of the
window, or use a separate window.
additional to the coordinates, further information as angles of
bezierpoint-lines or kind of connection (smooth, corner, symmetric, etd.) could
be filled in this form, whis is secundary important, compared with coordinates.

Reasons
Open Office has increased the quality of the Draw-Module by far and near to
products as Corel Draw, which has such an feature in the status bar.
Furthermore a good vectorized drawing software can substitute a CAD-software
(computer aided drawing). By giving a few tools for exact handling, the
performance can be rised. I know, that some professional pattent attourneys use
Corel Draw for producing technical ilustrations.
