penpixel-maya does not have anything like the modo pen tool but has several similar work flows. One is as stwert mentions extrude along a path, or you can just do a series of edge extrusions manually to create a ribbon of polygons, or you can repeat the append to polygon tool.
Those are your options.
I can see you are continuing to try a force a modo workflow in Maya and you are going to get frustrated. You need to seriously watch some tutorials in Maya, that demonstrate a Maya workflow.
Modo and the Modo workflow is more like ligthwave and as Daverave can probably attest as he successfully transitioned from lightwave to Maya the tools and workflows are different and you just have to let go of what you know in Modo.
Pick a subset of tools that work in Maya and learn the basic Maya workflows. The good news about Maya having a smaller set of tools there is less to learn. You just have to be willing to work with a smaller set of tools and some consistent Maya workflows.
