Delete all non-referenced geometry and external reference.Indicated features are likely to cause problems in the target system. In Creo Parametric use File -> Prepare -> ModelCheck Geometry Check. Before export, check for highlighted menu option Info -> Geometry Checks for design problems.To reduce the neutral file size (save time at import) use "Shrinkwrap functionality" or "Simplified Representation".To export mixed model structures, each model type should be saved as one part and transferred in assembly mode.Components of an assembly should have names no longer than 16 characters.The setting enable_absolute_accuracy yes needs to be included in configuration file config.pro.From the view of data exchange it is recommended to create models in Pro/ENGINEER with absolute accuracy from the beginning.The following settings are recommended up to Pro/ENGINEER Wildfire 5.0 / Creo Parametric 3.0 and AutoCAD 2017/Mechanical Desktop 2017
