Hi Frederik,

re:

You can use the Merge command for that:
https://moi3d.com/4.0/docs/moi_command_reference10.htm#merge

Select the whole object, type the Tab key to put focus in the bottom XYZ input, then type Merge <enter> and those fragmented edges will be combined.

A curve is its own separate object, it isn't connected to the solid.

To make a fillet on the solid you need to select edges which are part of the solid, not separate curve objects.
