Hi Jacklin, probably making a flat pattern and using Transform > Deform > Flow
https://moi3d.com/4.0/docs/moi_command_reference8.htm#flow

That would look something like this:

Draw a line and use Construct > Revolve to make cone surface:



Make one element using loft between 2 rectangles:



Transform > Array > Grid to replicate the loft to make the initial flat pattern:



Draw a plane underneath the entire array and then use Transform > Deform > Flow to map the pattern from the base plane onto the cone:
