New and changed functionality

SOLIDWORKS Partner Program

• See ISwAddin, ISwPEManager, ISwPEClassFactory, and ISwPEToken.

Sheet Metal Features

• Create and modify sheet metal swept flange features, optionally using sheet metal gauge table parameters. See ISweptFlangeFeatureData and ISheetMetalGaugeTableParameters.
• Initialize a sheet metal gusset feature using a smaller set of parameters and extend the feature using its feature data object. See ISMGussetFeatureData.
• Initialize a sheet metal edge flange feature using a smaller set of parameters and extend the feature using its feature data object. See IEdgeFlangeFeatureData.
• Also see IFeatureManager::CreateDefinition, and IFeatureManager::CreateFeature.

Other major enhancements 

• Vary the dimensions and locations of pattern instances in linear and circular patterns of parts and assemblies. See IInstanceToVaryOptions, ICircularPatternFeatureData::InstancesToVary, ICircularPatternFeatureData::GetInstanceToVaryOptions, ICircularPatternFeatureData::SetInstanceToVaryOptions, ILinearPatternFeatureData::InstancesToVary, ILinearPatternFeatureData::GetInstanceToVaryOptions, ILinearPatternFeatureData::SetInstanceToVaryOptions, ILocalCircularPatternFeatureData::GetModifiedInstance, ILocalCircularPatternFeatureData::GetModifiedInstances, LocalCircularPatternFeatureData::ModifyInstance, ILocalLinearPatternFeatureData::GetModifiedInstance, ILocalLinearPatternFeatureData::GetModifiedInstances, and ILocalLinearPatternFeatureData::ModifyInstance.
• Get or set whether to synchronize the configurations of pattern components with the configuration of the seed component in an assembly component pattern. See IChainPatternFeatureData::ForceUseSeedConfiguration, IDerivedPatternFeatureData::ForceUseSeedConfiguration, ILocalCircularPatternFeatureData::ForceUseSeedConfiguration, ILocalCurvePatternFeatureData::ForceUseSeedConfiguration, ILocalLinearPatternFeatureData::ForceUseSeedConfiguration, ILocalSketchPatternFeatureData::ForceUseSeedConfiguration, and IMirrorComponentFeatureData::ForceUseSeedConfiguration.
• IView::GetDisplayData4 fixes the bug in which IView::GetDisplayData3 prevents information being returned in IDisplayData (e.g., line, arc, polyline, and text counts).
• IView::GetSMBoundaryBoxDisplayData2 fixes a bug in which IView::GetSMBoundaryBoxDisplayData returns nothing.
• Export interference detection results to a *.xlsx or *.csv file. See IInterferenceDetectionMgr::ExportResults.
• Insert chain dimensions in a drawing document. See IModelDocExtension::InsertChainDimensions.
• Set cosmetic thread display quality when setting a drawing view's display mode. See IView::SetDisplayMode4 and IView::GetCThreadQuality.
• Get or set whether to include the dimension prefix, suffix, and tolerance in a dimension note. See INote::IncludeDimPrefixSuffixTolerance.
• For assemblies, perform advanced component selection using Category1 and Category2 criteria and save queries in XML format. See IAdvancedSelectionCriteria::AddItem2 and IAdvancedSelectionCriteria::GetItem2.
• Get all of the unobscured drawing components in a drawing view of an assembly drawing. See IView::GetVisibleDrawingComponents.
• For SOLIDWORKS Connected only:
  • Synchronize system options, file locations, and customizations with those of SOLIDWORKS Desktop. See ISldWorks::DownloadFromMySolidWorksSettings and ISldWorks::UploadToMySolidWorksSettings.
  • Get the type of 3DEXPERIENCE application that owns a given model. See IModelDocExtension::Get3DExperienceModelType.
