Rebuild errors in SolidWorks can halt your design process, but they are often fixable. This guide will walk you through the common methods to diagnose and resolve these errors, helping you get your model back on track.
Look for a red 'x' or a yellow warning symbol next to a feature in the FeatureManager Design Tree on the left side of the screen. This indicates the source of the rebuild error.
Right-click on the feature with the error and select What's Wrong? from the context menu. This will open a dialog box providing a description of the error, which can help you understand the root cause.
Right-click the feature again and choose Edit Feature. This will open its PropertyManager, allowing you to inspect its settings, references, and dimensions.
Analyze the feature's parameters based on the 'What's Wrong?' description. Common issues include dangling references (geometry that was deleted), missing sketch entities, or invalid dimensions. Adjust the settings to resolve the conflict.
Once you've made your corrections, click the Rebuild icon (it looks like a traffic light) at the top of the screen, or press Ctrl + B. If the correction was successful, the error icon will disappear.
Tips for Preventing and Managing Rebuild Errors
Drag the rollback bar up the FeatureManager tree to a point before the error occurred. This allows you to isolate the problem and rebuild the model one feature at a time to pinpoint the exact cause.
Right-click any feature and select Parent/Child to see its dependencies. Errors in a 'parent' feature will often cause errors in its 'child' features.
Whenever possible, create relations and dimensions to primary planes (Front, Top, Right) or the origin. These references are stable and less likely to change or be deleted, preventing future errors.
For certain features like fillets and drafts, SolidWorks offers the FeatureXpert tool. It can automatically diagnose and propose solutions to common rebuild problems.
