The following settings are recommended up to CoCreate Modeling 16.5 and SolidWorks 2016.

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.

SolidWorks - STEP Postprocessor

• To import a STEP file go to File -> Open… and select the file.
• Click on Options and the Import Options dialog box appears. Under General options following can be selected:
• Surface/solid entities: import surface and solid entities.
• B-Rep mapping: import the model using boundary representation. If not selected, SolidWorks attempts to knit surfaces into solids.
• Knit surfaces: imports as surfaces and tries to knit imported surfaces.
• Do not knit: imports as surfaces without knitting them.
• Free point/curve entities: imports free points and curve entities.
• Import as sketches
• Import as 3D curves
• Import multiple bodies as parts: Imports a multibody part as an assembly document. The multiple bodies are imported as part documents contained in the assembly. With this option cleared the multibody part imports as a part document that contains multiple imported bodies.
• Perform full entity check and repair errors: default is selected
• Customize curve tolerance: needed tolerance for the import can be entered here.
• Map configuration data (for STEP only): Imports STEP file configuration data plus geometric data. To import only the geometry this option must be left unchecked.
• The other available options are not applicable for the STEP import.
• Recommended options are to check Surface/solid entities, Try forming solids and Perform full entity check and repair errors.

SolidWorks – System

• Import errors are indicated in the history tree. By mouse right click over the model and choosing What’s wrong?, a detailed information will be displayed.
• Doing a Geometry check, the errors will be indicated in the model.
