Wes McDermott (the 3d ninja) takes a look at using NEX tools in maya, specifically using surface constraints for modeling re-topology workflow. Wes notes that NEX is soon coming for both OS X and Linux platforms, something that has been long awaited for sure.
Check out the post for Using NEX Tools in Maya for Re-Topology Workflow here.
NEX is a unique plug-in for Maya that includes a set of tools designed to increase the speed, accurracy, and efficiency of your workflow. Frequent actions like of manipulating components within Maya become more natural due to the unique integration of all the NEX selection and transformation tools. Arduous jobs like resurfacing meshes can actually be fun using the NEX Quad Draw tool. Common polygon modeling tasks like Splitting faces, Connecting edges, or beveling have been reworked with maximum efficiency and interactivity in mind. Best of all, NEX does all this without leaving any custom nodes in your scene, or introducing any scene plug-in dependencies.
