Guillaume FERRACHAT updates his Maya Curve on Mesh tool, which as the name suggests allows you to draw curves on selected meshes. Curve on Mesh 2.0 can now draw a curve on multiple selected objects without having to combine them.
A selection of more than one object works seamlessly as one when drawing a curve with the tool. Another new feature for the Maya tool is that you can now draw a mesh on the selected objects. This is similar to the quadraw function of Maya’s Modeling Toolkit.
The Curve on Mesh tool can be downloaded from CreativeCrash as freeware here: Maya Curve on Mesh Script.
Guillaume has also develop and released a new tool that is kind of parallel to Curve on Mesh. The Simplify Curve script for Maya offers a few different algorythms to simplify selected curves.
