5 Ways to Reduce Engineering Errors in SolidWorks with Automation

Engineering errors are expensive. A wrong part number on a BOM can trigger a procurement mistake that costs thousands. An incorrect export format can delay manufacturing by days. A missing drawing can halt an entire production run. The frustrating truth? Most of these errors are preventable. Here are 5 ways to reduce engineering errors in SolidWorks using automation—and how much each one can save your team.

1. BOM Mistakes: The Most Expensive Line Items

Bill of materials errors are the single most costly category of engineering mistakes. A study by the Aberdeen Group found that BOM errors account for up to 30% of all engineering change orders. Each ECO costs an average of $1,500–$3,000 in administrative overhead alone—before counting the impact on production schedules and material waste.

The root cause is almost always manual data entry. When engineers copy part numbers from SolidWorks into spreadsheets, transposition errors, missed components, and incorrect quantities are inevitable. The more complex the assembly, the higher the error rate.

2. Naming Inconsistencies: Death by a Thousand Variants

"BRACKET-001", "bracket_001", "Bracket 001 (rev2)", "MM-BKT-001-A". When file names don't follow a strict convention, everything downstream breaks. Suppliers can't match files to their purchase orders. PLM systems create duplicate records. Quality teams can't verify they have the right revision.

Naming inconsistencies compound over time. What starts as a minor annoyance becomes a significant source of confusion and rework as projects grow. Teams spend hours reconciling file names, and the risk of using the wrong file version is always present.

3. Wrong Export Formats: When Your Supplier Can't Open the File

Different suppliers and downstream processes require different file formats. Your laser cutter needs DXF. Your machining vendor wants STEP AP214. Your client requires IGES for their legacy CAM system. Sending the wrong format—or the right format with wrong settings (AP203 instead of AP214, inches instead of millimeters)—causes delays and frustration.

Manual exports are particularly error-prone here because format settings are buried in dialog boxes that engineers click through quickly. It's easy to forget to switch from AP203 to AP214, or to miss the unit setting when exporting DXF files for an international supplier.

4. Missing Drawings: The Ones You Didn't Know Were Missing

When preparing a drawing package for release, it's surprisingly easy to miss individual drawings—especially in large assemblies with 100+ components. A part might not have a drawing yet. A sub-assembly drawing might exist but reference an old configuration. A purchased component might need a specification sheet instead of a drawing.

Missing drawings are typically discovered at the worst possible time: when the manufacturer is ready to start production. The resulting scramble to create missing drawings under time pressure introduces additional quality risks—rushed drawings are more likely to contain errors.

5. Revision Confusion: Which Version Is Current?

Revision control in SolidWorks environments without PDM is notoriously difficult. Engineers save files with revision suffixes ("_RevB", "_v3", "_FINAL"), but there's no enforced system to ensure everyone is working with the latest version. Exported files compound the problem—when you manually export 50 STEP files, how do you verify that each one reflects the current revision?

Even teams with SolidWorks PDM face revision challenges during export. The PDM vault tracks revisions internally, but exported files for external distribution need explicit revision identification in filenames and metadata. Manual processes often lose this link between the vault revision and the exported file.

The Cumulative Impact of Error Reduction

Each of these five error types is manageable in isolation. The real damage comes from their cumulative effect. A team producing 10 assemblies per month with even a 5% error rate across these categories is dealing with dozens of corrections, ECOs, and delays annually.

SolidWorks quality automation isn't just about working faster—it's about working correctly the first time. Automation eliminates the categories of errors that manual processes inevitably produce. The result is fewer ECOs, faster releases, happier suppliers, and engineering teams that spend their time on design instead of damage control.
