2D Drawing production with missing lineword

Hello All, I am having an issue with the “Produce 2D drawing” function in Rhino 6. For some 3dm files, when I use this tool, the 2D drawing is produced but is missing the bulk of the linework. Any suggestions on a fix?

Can you send some capture screens to understand better what you obtain from make2d ?
Increasing or decreasing the meshing parameters could help to obtain a better result.
