Project: CAD Automation: Custom SolidWorks VBA Tools
I have developed a suite of custom VBA automation tools for SolidWorks to streamline engineering workflows, eliminate manual data entry, and enforce data consistency across design teams.
Tool 1: Configuration Property Manager

CHALLENGE
Each detail is identified in the following manner (designation, name, section, developer, etc.) during the design phase. This information is currently used to fill in the key letters in drawings and formulas. The interface makes these operations faster.
SOLUTION
Developed a custom VBA UserForm with:
Standardized input fields: Designation, Name, Section, Letter, etc.
Drop-down lists for some data lists that are edited in a txt file
One-click application of all properties specified in the form to the active configuration
Multi-configuration support – batch update of all configurations in a single run
ADVANCED FEATURE: Virtual Components Integration
Implemented support for SolidWorks Virtual Components — a powerful technique that allows engineers to add BOM items (documentation, paint, hardware kits, spare parts, consumables) without creating physical .sldprt files. This dramatically reduces file management overhead in PDM systems.
Use cases:
Documentation packages (manuals, certificates)
Paint and coating materials
Sets of kits
Spare parts sets
Lubricants and consumables
KEY ACHIEVEMENTS
✓ Reduced property entry time by 85% (from 10 min/part to 1.5 min)
✓ Eliminated data entry errors — 100% consistency across all drawings
✓ Reduced PDM database size by 30% (fewer virtual part files)
✓ Enforced company naming standards automatically



Tool 2: Automated BOM Generator & Excel Export



CHALLENGE
Manually generating bills of materials (BOMs) for complex assemblies took 2+ hours per project and was prone to human error, especially when working with a large number of assembly executions.
SOLUTION
Developed a VBA macro that:
Traverses the entire assembly tree and extracts all component properties
Reads data from the BOM table and generates a bill of materials (BOM) from the obtained information
Distributes elements into sections. Within the sections, the order is in accordance with the Unified System for Design Documentation (ESKD).
Exports structured data to Excel with custom formatting and formulas
Works with single and group BOMs. It is possible to select versions when generating a BOM
Creates an Excel file in the drawing folder with the correct name
If the number of versions in the standard BOM form is exceeded, an additional document with the remaining versions is created
KEY ACHIEVEMENTS
✓ Reduced BOM generation time from 2 hours to 5 minutes (96% time savings)
✓ Processed 10+ configurations simultaneously
✓ Zero manual data entry — eliminated transcription errors
✓ Exported Excel files ready for ERP integration (1C, SAP)
