The following settings are recommended up to CoCreate Modeling 16.5 and Autodesk Inventor 2017.

OneSpace Designer – System

• Components of an assembly should have names no longer than 16 characters.
• System accuracy should be set prior to modelling.
• Recommended values are 10-6 mm, 10-5 mm, 10-4 mm.
• The smallest extent value (e.g. edge length) can be set under:
• SystemSetting ->Advisor/Check Setting -> min Edge
• All Advisor Checks (voids, nonmanifold, knife edge, min edge) should be active while modeling the part.
• Complete body checks should be done frequently during design and prior to export to STEP.

OneSpace Designer - STEP Preprocessor

• When invoking the STEP export choose as option target system e.g. (CATIA IBM) or CATIA (debis) or Pro/ENGINEER.
• If, in case of an assembly export, the option Assemblystructur/Shared Parts is set ON, individual colors of instances cannot be exported.
• If the target system cannot process assembly structure information or geometric transformation, then you should select NO to suppress this information.
• Hybrid models must be exported with multiple products. You can also use the Structure Browser to make your selection. If you try to specify a part by clicking in a viewpart, you will select only faces or edges instead of the whole part.

STEP File

• No adjustment is necessary.

Inventor - STEP Postprocessor

• To import a STEP File please choose File -> Open... and select STEP file
• It is recommended to import the STEP files first without any automatic healing (in options selectable).
• The import log file "filename.xli" gives further information.

Inventor – System

• Shaded view is helpful and gives a first impression of the model quality.
• A volume calculation of the imported model gives more information about a successful import of a solid.
