How to Automatically Generate Drawings in SolidWorks

Introduction

Creating engineering drawings is one of the most important stages of the product design process. However, manually generating drawings for every part and assembly can be repetitive, time-consuming, and prone to errors—especially when working with large projects or product families.

With SolidWorks Automation, engineers can automatically generate drawings, insert standard views, add dimensions, create Bills of Materials (BOMs), and export files in just a few clicks. By using SolidWorks API, VBA, or C#, companies can significantly reduce design time while maintaining consistency across projects.

In this blog, we'll explore how automatic drawing generation works and why it's becoming an essential part of modern CAD automation.

What is Drawing Automation in SolidWorks?

Drawing automation is the process of using macros or the SolidWorks API to create engineering drawings automatically from 3D models.

Automation can perform tasks such as:

• Create new drawing files

• Insert standard drawing views

• Generate section and detail views

• Add dimensions and annotations

• Create Bills of Materials (BOMs)

• Insert balloons

• Apply drawing templates

• Export drawings as PDF, DXF, or DWG

This reduces manual work and ensures every drawing follows company standards.

Why Automate Drawing Creation?

Manual drawing creation often involves repeating the same steps for every design.

For example:

• Opening a drawing template

• Inserting model views

• Adding dimensions

• Creating BOMs

• Exporting PDFs

• Saving files with the correct names

When these tasks are automated, engineers save valuable time and reduce the chances of errors.

Benefits of Automatic Drawing Generation

Save Engineering Time

Generate complete drawings in minutes instead of spending hours on repetitive drafting tasks.

Improve Accuracy

Automation applies predefined templates, dimensions, and annotations consistently, reducing manual mistakes.

Standardize Documentation

Ensure every drawing follows company drafting standards, title blocks, and naming conventions.

Faster Design Updates

When the 3D model changes, automated drawings can be updated quickly without recreating documentation.

Increase Productivity

Engineers can focus on design improvements while automation handles repetitive documentation.

How Automatic Drawing Generation Works

A typical automation workflow includes:

Step 1: Open the 3D Model

The automation application opens the required part or assembly.

Step 2: Create a Drawing

A new drawing is generated using a predefined company template.

Step 3: Insert Drawing Views

Standard views such as Front, Top, Right, and Isometric are placed automatically.

Step 4: Add Annotations

Dimensions, notes, center marks, and balloons are inserted based on company standards.

Step 5: Generate BOM

For assemblies, a Bill of Materials is created automatically.

Step 6: Export the Drawing

The finished drawing is saved in formats such as PDF, DWG, or DXF for manufacturing and documentation.

Features That Can Be Automated

SolidWorks drawing automation supports:

• Drawing creation

• Standard view generation

• Section and detail views

• Automatic dimensions

• GD&T annotations

• BOM generation

• Balloon insertion

• Revision table updates

• PDF, DWG, and DXF export

• Batch drawing generation

Real-World Example

A manufacturing company produces over 200 custom machine components each month.

Before Automation

Engineers manually:

• Created drawings

• Inserted standard views

• Added dimensions

• Generated BOMs

• Exported PDFs

Average time per drawing: 25–30 minutes

After Automation

Using the SolidWorks API:

✔ Drawings are created automatically.
✔ Standard views are inserted instantly.
✔ BOMs and annotations are generated automatically.
✔ PDF and DWG files are exported with predefined naming conventions.

Average time per drawing: Less than 5 minutes

The company significantly reduced documentation time while improving consistency and accuracy.

Best Practices

To build efficient drawing automation solutions:

• Use standard drawing templates.

• Keep automation scripts modular and reusable.

• Validate model data before generating drawings.

• Implement proper error handling.

• Follow company naming conventions.

• Test automation with different part and assembly types.

• Document your code for easier maintenance.

These practices help create reliable and scalable automation tools.
