You can rotate the object. From Import Object --> Move --> Rotate Bank or Rotate Pitch depending on where the true Up axis is on the model.
However, you are best to fix the axis from the export process in the source (ArchiCAD) modelling tool so that as you do further changes to the source model it is exported and re-imported correctly for the correct axis for Lumion to save time.
Check the ArchiCAD import forum topic and search, I think the answer for which axis is up in ArchiCAD is somewhere around, depending on what format you export to.
