Hi Olivier, I'll wait when you're ready to TRY to help with (if you are interested in):

• Inquirying (coordinates of the points / vertices, lengths, areas, etc.)
• Diagnostic (points too close, etc ...)
• Building (points at known distances from other points, under angles known from a base, intersections, fillet, trim, etc. ..)
• Linear interpolation (points at absolute or percentage distance along a straight line)
• Quadratic interpolation (arcs, circles, ellipses, partabole)
• Cubic interpolation (Hermite, Bezier, spline, polynomial)
• Editing (coordinates updating by the keyboard, line simplification with the RDP, VW and my own algorithm)
• Transformation (collimation 1, 2 + or 3 points); It will need to clean some things already exposed in your plugin or in native functions of qgis;

all the best giuliano curti
