I have created a new plugin editor for MCM 1. It allows you to copy an existing plugin and then edit/add pieces to it. You can lay tracks out in 3D and then save the compiled track for use in MCM 1.

The piece editor has options to let you create a profile of a jump and then apply it to the whole piece and smooth it in various ways. If the piece's shape works the same way in both directions then you can actually place two shapes. One for North/West and one for South/East.
