Hiya, In C3D you have a couple of options. the easy option I use most of the time is to switch off GeoReferencing so that you can move the data away from it’s locked coordinates. I then do a save as and shift the whole model so that 0,0,0 sits roughly central to my model. Open 3dsMAX and Import the dwg file. You can then export as datasmith or fbx into Twinmotion. Other option is to keep the GeoReferencing on in C3D and go to Output and then choose Export to 3ds MAX. This saves it as a VSP3D file. You can then go to your Civil View pull down in 3dsMAX and use Geometry Import, Civil 3D (VSP 3D) file and then choose what you want to Import. 3dsMAX will then look for the centre of mass of your data and use that as 0,0,0 for object importing. It will also give you a read out of the shift it has applied. Same principal then for the export to Twinmotion. Good Luck
