# Hi jmvillar, Commenting post [339](/?blog/2013-339): Hi jmvillar, Unfortunately I'm not familiar with frenet and transition items.. If you want to transform object following math defined curves, I'm afraid this is still not implemented in FreeCAD... But in any case, you'd better head to the FreeCAD forum at , there you'll be able to get help from people more into that area than me...
