Here is my complete work through to get near perfect results
from MOI importing IGES and exporting .lwo from SW 2008 to modo 301.
Open assembly in SW"Save as" IGES .igsUnder Options - Solid Surface features - Output as - "CHANGE TO" - Manifold Solid B-rep Object type 186.
Surface representation/system preference - standardcheck box next to Export 3d curve featuresUse High Trim curve accuracy
IGES asembly structurecheckSave all components of an assembly in one file Flatten assembly heirarchy
close / minimize SW
Open MOISet - options - general - to metersSelect UNIT OPTIONSSet Default Unit system - to Meters
Select all and rotate 90 around origin - This sets my model flat and centered on the work planes - you may or may not have to do this.
SAVE AS - .LWO
I use the following settingsAngle 12Divide larger than .25 curvedAvoid smaller than .01 which is around 2" on my meshAspect Ratio Limit 2
Oen .LWO in modo
Model should be near perfect geometry in Modo , with each part individually selectable for materials.
I will (probably) post some renders in the next few hours.
