SOLIDWORKS PDM

What is SOLIDWORKS PDM?

SOLIDWORKS PDM (Product Data Management) is a system used to securely store, organize, manage, and control engineering files such as CAD models, assemblies, drawings, and related documents. It helps teams maintain the correct version of designs and manage the entire design workflow.

Key Features of SOLIDWORKS PDM:

SOLIDWORKS PDM provides version control, file check-in/check-out, revision management, user permissions, file search, workflow management, and automatic file references. It also prevents multiple users from accidentally overwriting each other’s work.

Benefits of SOLIDWORKS PDM:

PDM improves data security, collaboration, design organization, and productivity while reducing duplicate files, incorrect revisions, and accidental data loss.

How SOLIDWORKS PDM Works:

Design files are stored in a centralized PDM vault. Users check out files to work on them and check them in when finished. The system records file versions and controls who can access, modify, approve, or release each file.

Key Takeaway

PDM Vault → Check Out → Modify → Check In → Version Control → Approval → Release

SOLIDWORKS PDM

Introduction

SOLIDWORKS PDM (Product Data Management) is a data-management system designed to help engineering teams store, organize, control, and manage CAD files and related documents.

Instead of keeping SOLIDWORKS parts, assemblies, drawings, and documents scattered across individual computers or network folders, PDM provides a controlled environment where teams can manage files, revisions, approvals, and access permissions.

SOLIDWORKS PDM is especially useful for organizations working with large numbers of CAD files and multiple engineers or designers.

What is SOLIDWORKS PDM?

SOLIDWORKS PDM is a product data management solution used to control engineering files throughout their lifecycle.

It can manage:

SOLIDWORKS parts
SOLIDWORKS assemblies
SOLIDWORKS drawings
CAD references
PDFs
Office documents
Manufacturing documents
Specifications
Revision information

Key Features of SOLIDWORKS PDM

1. Centralized File Management

SOLIDWORKS PDM stores engineering data in a controlled PDM vault.

2. Check-In and Check-Out

One of the core PDM features is check-in/check-out.

Check Out

A user checks out a file when they need to modify it.

Edit

The user makes changes to the CAD model.

Check In

The updated file is checked back into the vault.

This helps prevent multiple users from accidentally overwriting each other’s changes.

3. Version and Revision Control

SOLIDWORKS PDM maintains information about file versions and revisions.

4. File References

SOLIDWORKS assemblies often contain references to many parts and subassemblies.

PDM helps maintain these relationships.

For example:

Assembly

→ Part A

→ Part B

→ Part C

→ Subassembly

→ Drawing

This is particularly important for large assemblies.

5. Workflow Management

PDM can be configured to control the movement of files through engineering processes.

A typical workflow might be:

Work in Progress

↓

Engineering Review

↓

Approved

↓

Released

↓

Obsolete

Different users can be given permission to move files between these states.

6. User Permissions

Administrators can control who can:

View files
Edit files
Check out files
Check in files
Change states
Approve designs
Release revisions

This helps protect important engineering data.

7. Search

SOLIDWORKS PDM provides tools for finding files and engineering information.

Users can search based on information such as:

File name
Description
Part number
Revision
Author
Custom properties
File status

This is much more efficient than manually searching through large folder structures.

8. Bill of Materials (BOM) Management

PDM can work with SOLIDWORKS assemblies and provide access to Bill of Materials (BOM) information.

For example:

Product Assembly

→ 1 × Housing

→ 4 × Bolts

→ 2 × Bearings

→ 1 × Shaft

This can help engineering and manufacturing teams work from consistent product information.

9. Audit Trail

PDM can maintain information about changes made to files.

Organizations can track information such as:

Who modified a file
When it was changed
Which revision was created
Which workflow state it entered

This improves traceability.

10. Automatic File References

When CAD files are moved or managed through PDM, their references can be maintained more reliably.

This is particularly valuable for assemblies containing many dependent files.

Benefits of SOLIDWORKS PDM

1. Prevents Data Loss

Controlled file management reduces the risk of accidentally deleting or overwriting important engineering files.

2. Prevents Duplicate Work

Team members can see whether a file is already being edited.

This reduces the possibility of two engineers unknowingly working on conflicting versions.

3. Improves Revision Control

Teams can clearly distinguish between different versions and released revisions.

4. Improves Collaboration

Engineers, designers, manufacturing teams, and managers can work from a controlled source of engineering data.

5. Saves Engineering Time

Instead of manually searching through folders, users can search the PDM vault for the required design or document.

6. Protects Design Data

Permissions and controlled workflows help restrict unauthorized modifications.

7. Improves Traceability

Teams can determine:

Who changed it?

When was it changed?

Which version was used?

Was it approved?

This is especially useful in regulated or quality-controlled engineering environments.

8. Supports Engineering Change Processes

PDM can help organizations manage design changes through controlled workflows.

How SOLIDWORKS PDM Works

A simplified PDM workflow looks like this:

Step 1: Create a CAD File

An engineer creates a SOLIDWORKS part, assembly, or drawing.

Step 2: Add It to the PDM Vault

The file is stored and managed within the PDM system.

Step 3: Check Out

The engineer checks out the file before modifying it.

Step 4: Edit

The engineer makes the required design changes.

Step 5: Check In

The updated file is checked back into the vault.

Step 6: Review

The file can move through an engineering review workflow.

Step 7: Approve

An authorized person approves the design.

Step 8: Release

The approved revision becomes available for downstream users such as manufacturing or purchasing.

Example: SOLIDWORKS PDM Workflow

Imagine a company designing a pump assembly.

Engineer

Creates:

Pump housing
Shaft
Impeller
Cover
Assembly
Manufacturing drawing

PDM

Manages the relationships between these files.

Engineering Review

The assembly is checked by another engineer.

Approval

The design is approved.

Release

The manufacturing department receives the released revision.

If the pump housing is later modified, PDM can manage the new version/revision and maintain the history of the previous design.

SOLIDWORKS PDM vs. PLM

These terms are related but not identical.

PDM

Focuses primarily on engineering/product data management.

Examples:

CAD files
Revisions
File workflows
Engineering documents
Access control

PLM

Product Lifecycle Management generally covers a broader product lifecycle, potentially including:

Product planning
Engineering
Manufacturing
Supply chain
Quality
Service
Product lifecycle information

In simple terms:

PDM = Manage product data

PLM = Manage the broader product lifecycle
