> Now convert Points to Control Points is the new challenge!

Use SavePointFile to write the point objects to a text file (use the OSX version even for Windows):

Then use ImportPointFile to read in the points, it has an option to make a curve out of them:

again use the updated version that works with OSX, the original versions of these only work with MoI v2, the ones updated to use MoI's built in cross platform functions for reading and writing text files will work on MoI v3/v4 on both Mac and Windows.

One thing to note though is that the ordering of the points is significant when making a curve out them.
