Why does registration fail?

If registration or activation fails, please check the following: - Make sure antivirus software is disabled during installation. - If you are using a company-managed computer, IT security policies may restrict installation or activation. Please contact your IT administrator. - If the installation folder is protected by encryption software, decrypt the folder before installation. If the issue persists, please contact technical support for assistance.

What should I do if the plugin does not appear or cannot be enabled after installation?

Please try the following troubleshooting steps: - Avoid installing JLCCAN on the C: drive, as system permission restrictions may affect loading. - Make sure the installation path does not contain special characters (such as # or @). - Temporarily disable antivirus software and reinstall the plugin. - If you are using Windows 7, ensure that .NET Framework 4.8 is installed. If the issue persists, please contact technical support for remote assistance.

Does JLCCAN support SOLIDWORKS drawing automation? How can I create a drawing for a single part?

Yes. JLCCAN includes a SOLIDWORKS drawing automation tool that helps engineers automatically generate engineering drawings for individual parts and assemblies, reducing repetitive drafting work and improving efficiency. You can select a part and run the drawing generation command to create a drawing based on predefined template settings. The feature also supports generating drawings for selected components within assemblies.

How can I batch rename files in SOLIDWORKS? Will drawing names be updated automatically?

Yes. JLCCAN provides a SOLIDWORKS batch rename tool that allows you to rename part numbers, parts, assemblies, and file names in bulk. When a part or assembly file is renamed, the associated drawing file name is updated automatically, helping maintain consistency across related files and reducing manual work.

Can I filter BOM data by multiple conditions?

Yes. JLCCAN's SOLIDWORKS BOM management tools support filtering by multiple conditions. To apply multiple filters, combine the criteria using the '+' symbol. For example: Machined Parts + Sheet Metal Parts The BOM tools also help engineers organize bill of materials data, review component information, and prepare BOM data for export and manufacturing processes.

Core Tools for SOLIDWORKS Productivity

Auto Hole Generation
- 5 Hole Types
- 10× Faster
Five hole types, counterbore, countersink, tapped, drilled, and threaded, are placed in one click. Up to 10× faster than the native Hole Wizard workflow.
Hole Inspection
- Fast Hole Validation
Detect missing, misaligned, or inconsistent holes across assemblies instantly.
Auto Fastener Assembly
- Automatic Spec Recognition
Detects mating geometry and assembles common fasteners, screws, washers, and nuts, with the correct specification automatically applied.
Drawing Automation & Auto-Dimensioning
- One-Click Drawings
- Auto-Applied Dimensions
Generates three-view drawings instantly. Applies linear dimensions and dimension chains automatically — especially powerful for plate components.
Advanced BOM
- Flat & Hierarchical BOMs
- Bulk Data Editing
Supports flat BOMs and multi-level hierarchical BOMs. Quickly edit BOM data in bulk and export BOM to Excel with one click.
Quick Features
- Complex Geometry in One Click
Snap-ring grooves, retraction grooves, edge fillets, holes on cylindrical faces, features that normally take five sketches, generated instantly.
Batch Manager
- Format Conversion
- Bulk Renaming
- Property Edits
Rename files in bulk with smart rules. Convert to PDF, DXF. Edit properties, separate drawing numbers, swap title blocks, merge CAD drawings, all in batch.
Duplicate Detector
- One-Click Part Replacement
Finds parts with identical geometry but different filenames, and replaces every instance with one click. Cleans up years of file drift in minutes.
Smart Design Library
- Instant Library Access
Save standard parts to your design library. When inserted into assemblies, library links are automatically detached to protect the original files.
