Re-topologising CAD data using modo: part deux (part one here)
An alternative to making curves and creating polygon patches with them has always been to draw polys directly over the existing model using Constrain to Background
The new Pen tool options allow you to quickly build strips of quad polygons to follow the shape of your target object.
You can the adjust the resulting vertices with the Element Move tool whilst using Constrain to Background to get a smooth poly flow.

However, in modo 401 there is an even easier way...
You can sketch out some honking big quads within the boundary of the surface that you are re-modelling.
The result is not particularly accurate but does at least follow the boundary of the surface
Using Loop Slice (or similar tool) you can then create some more evenly spaced polys
Subdivision on, you can see this grossly inaccurate.
modo 401's Constrain to Background is so good however that we can just Push the mesh into the underside of the existing data to get a very accurate new surface
The result is excellent as you can see. We can use all the tools as before to connect sections and finish edges etc., but the ability to create base surfaces really quickly will speed up this sort of work greatly in 401
