I am pretty new to Mastercam, and just getting started using the API. My company is trying to create a fully automated program using C# and .Net Hooks. The program will import a surface (assumed to be curved in X and Y), an artwork wireframe (DXF), and a text wireframe (AI). We want to roll all the wire frame geometry in X and Y then project it onto the surface. Using the Mastercam GUI we found this technique gave good results and minimized warping near the edges. So far we have been able to figure out how to import and select the wireframe geometry, as well as simple translations with the API. There are a few GUI functions that we have not been able to find out how to use through the .NET-Hook API. -Transform->Roll -Transform->project -Toolpaths->multiaxis curve Any direction or help is greatly appreciated. - Nick
