I completed the conversion of three medieval relics at WooodMarvels.com to DXF format, they are both Mangonel Siege Weapons and Medieval Castle Bank. You can find them easily by going to Theme / Medieval / Relics, the models were not changed other than the new file format being made available.
Medieval Castle Bank: 3D Assembly Animation
Mangonel Siege Weapon: 3D Assembly Animation
Mangonel Siege Weapon B: 3D Assembly Animation
