not sure that is suitable for you...

You are hero! I do not know how to appreciate.
Solid edge works great. So i can export as STEP file and import into moi3d.

Thank you very much Frenchy!

Just to mention that i spent whole day yesterday to find a way to convert JT to STEP file.
I understand that JT file is a specific one and only few softwares can work with that and it cost thousands of dollars.
I tried FreeCad, JT2GO, CAD Assistant, MeshLab, Sketchup and so on.
Most of free softwares allow you to view JT files but not exporting.
So Thanks Again for everyone!

So the free version of Solid edge was working fine ?

yes it works fine. A little bit laggy but i guess it is due to graphic card.
