SOLIDWORKS PDM Copy Tree: Challenges and How Cloud PDM Can Offer a Better Solution

‍

Introduction

What is SOLIDWORKS PDM Copy Tree and Why is it Important?

The SOLIDWORKS PDM Copy Tree feature is a powerful tool that allows users to copy complete projects, including all referenced files, while maintaining crucial dependencies between parts, assemblies, and drawings. Unlike a simple file copy operation, Copy Tree ensures that all relationships between components remain intact, preventing broken references and streamlining project duplication.

For engineers and product designers working with large SOLIDWORKS assemblies, Copy Tree is an essential tool when creating variations of a product, making design modifications, or duplicating files for a new project.

‍

How Copy Tree Differs from Pack and Go (And Why PDM Users Prefer It)

While SOLIDWORKS Pack and Go is often used for copying assemblies in standard SOLIDWORKS environments, it lacks the advanced reference-tracking capabilities of Copy Tree. Here’s how they compare:

While Pack and Go is useful for local projects, PDM users prefer Copy Tree because it keeps files linked, structured, and correctly referenced within a controlled vault environment.

Why Maintaining File References is Critical

One of the biggest challenges when copying SOLIDWORKS assemblies is ensuring that all related files—parts, sub-assemblies, drawings, and additional linked documents—are correctly referenced in the new project.

Without proper reference management, common issues include:

• Broken references, where copied parts no longer link to their parent assemblies.
• Duplicate file names, leading to conflicts in the PDM vault.
• Accidental overwrites, where copied files replace existing versions.

The Copy Tree feature helps mitigate these risks, but it’s not without its challenges, especially in complex multi-user PDM environments.

‍

1. Understanding SOLIDWORKS PDM Copy Tree

1.1 How Copy Tree Works in SOLIDWORKS PDM

The Copy Tree function is accessed directly from the SOLIDWORKS PDM vault interface. Here’s a step-by-step guide:

Step 1: Accessing Copy Tree

1. Open SOLIDWORKS PDM Vault.
2. Navigate to the assembly or file you want to copy.
3. Right-click and select Tools → Copy Tree from the menu.

Step 2: Choosing Copy Settings

Once the Copy Tree dialog box opens, users can configure various options:

• Version to Use:
  
  • Latest – Copies the most recent version of each file.
  • Referenced – Copies the version referenced by the top-level file.
• Copy Type:
  
  • Files – Copies the selected files into the destination.
  • Compressed Archive – Creates a .zip file for easy transfer.
• Additional Options:
  
  • Include Drawings – Ensures that related 2D drawings are copied.

• Include Simulation Results – Keeps associated FEA or CFD files.
• Regenerate Serial Numbers – Assigns new PDM serial numbers to copied files.

Step 3: Transforming File Names

To prevent duplicate file names and conflicts, Copy Tree allows:

• Adding Prefixes/Suffixes – Helps distinguish copied files from originals.
• Renaming with Serial Numbers – Ensures new files follow an automated naming scheme.
• Replacing Text in File Names – Useful for updating project codes or version numbers.

Step 4: Selecting the Destination and Executing the Copy

• Users browse to the new folder location and ensure that all paths update correctly.
• Once everything is set, clicking "Copy" begins the duplication process.

1.2 Common Use Cases for Copy Tree

1. Duplicating Projects for New Versions

• When a new product revision is needed, engineers can copy an existing project while keeping previous versions intact.
• Copy Tree ensures that all dependencies and file structures remain correct.

2. Reusing Assemblies with Minor Modifications

• If a company wants to create a new variant of an existing product, Copy Tree allows for efficient duplication without disrupting the original design.

3. Creating Variations of a Standard Design

• Standard parts or assemblies often need small adjustments for different configurations.
• Copy Tree preserves the core structure while allowing custom modifications.

4. Using Copy Tree Across Multiple Vault Locations

• When teams work in different geographic locations, Copy Tree helps replicate files between PDM vaults.
• However, vault replication can be slow, leading to delays (covered in the next section).

2. Issues and Challenges with SOLIDWORKS PDM Copy Tree

2.1 Performance Bottlenecks and File Management Challenges

While Copy Tree is a useful feature, it can become slow and inefficient, especially for large assemblies or multi-user environments.

Problem 1: Slow Copy Operations for Large Assemblies

• When copying assemblies with hundreds of components, PDM must scan and update all references, which can take time.
• Solution:
  
  • Run Copy Tree during off-peak hours to reduce server load.
  • Use local caching to improve speed.

Problem 2: Issues with Vault Replication in Multi-Site Setups

• When using Copy Tree across different PDM vault locations, file synchronization delays may occur.
• Solution:
  
  • Ensure that vault replication settings are optimized for large transfers.
  • Use PDM workflows to track file movements and avoid duplication.

Problem 3: Network Dependency Affects Performance

• Copy Tree relies on stable network connections to access files from the PDM server.
• Slow networks lead to long copy times and failed operations.
• Solution:
  
  • Use a 1 Gbps LAN or fiber connection for optimal speed.
  • Avoid copying large assemblies over VPNs with high latency.

2.2 Reference Management Issues

Problem 1: Broken References After Copying Files

• If Copy Tree isn’t configured correctly, assemblies may lose their file dependencies.
• This leads to errors when opening projects, requiring manual reference fixing.
• Solution:
  
  • Use Preserve Relative Paths to keep file structures intact.
  • Double-check references before completing the copy process.

Problem 2: Maintaining Correct File Dependencies

• Some projects include linked files like:
  
  • Excel BOM sheets
  • External simulation results
  • Library components
• If Copy Tree does not copy these correctly, the new project may be incomplete.
• Solution:
  
  • Manually verify that all linked files are included in the copy.
  • Use PDM reference search tools to locate missing files.

Problem 3: Unexpected Reference Duplication

• Copy Tree may accidentally duplicate parts or assemblies, causing file conflicts in the vault.
• Solution:
  
  • Use PDM Search to check for duplicate file names.
  • Enable serial number automation to ensure unique identifiers.

2.3 File Naming and Serial Number Challenges

One of the most common and frustrating challenges when using Copy Tree in SOLIDWORKS PDM is ensuring that file names remain unique, structured, and easy to track. In large design teams and multi-user environments, improper naming can lead to duplication conflicts, loss of reference integrity, and delays in project setup.

Confusion When Renaming Multiple Files Using Prefixes or Serial Numbers

When copying large assemblies, designers often need to rename files to differentiate them from the originals. Copy Tree provides transformation options such as:

• Adding Prefixes or Suffixes (e.g., "RevB_" or "_Prototype")
• Renaming with Serial Numbers (automated unique identifiers)
• Replacing Text in File Names (changing project numbers, part IDs, or version tags)

Common Issues Encountered

• Unintended Duplicate File Names – If a prefix or suffix is not added properly, files may be copied with the same name as existing files, leading to conflicts when checking them into the vault.
• Loss of Reference Tracking – If serial numbers or custom renaming fail to follow a structured format, it becomes difficult to trace copied files back to the original designs.
• Overwritten Naming Conventions – Copy Tree might apply serial numbers in an unexpected order, leading to naming conflicts or making it difficult to find files in the vault.

Solution & Best Practices

• Standardized Naming Conventions – Establish company-wide rules for file renaming to avoid inconsistent prefixes and serial numbers.
• Pre-Copy Tree Validation – Use PDM Search to check for existing file names before copying and renaming to avoid duplication.
• Use PDM Variables for Automated Naming – Configure custom PDM data card fields to automatically generate logical names based on project, part type, and date.

Difficulty in Tracking and Verifying Renamed Copies in a Large Vault

With hundreds or thousands of files copied in a large PDM vault, users often struggle to:

• Find and verify renamed copies
• Ensure correct serial number assignment
• Validate that the correct drawings and parts were copied

Common Issues

• Misplaced files after renaming – If file names are not correctly referenced in assemblies or drawings, they may not appear where expected.
• PDM Search Complexity – Searching for files in the vault becomes difficult when serial numbers don’t follow a predictable pattern.

Solution & Best Practices

• Use Check-In Comments – Add detailed descriptions when checking in copies, making them easier to track.
• Leverage Custom Columns in PDM – Display original vs. renamed file names in the vault to compare copies quickly.
• Automate Serial Numbering with a Defined Format – Define fixed-length serial numbers and include prefixes related to project numbers or design revisions.

Automated Renaming Conflicts, Causing Delays in Project Setup

When renaming files during Copy Tree, PDM automatically applies serial numbers and transformations. However, errors occur when:

• The PDM database generates duplicate serial numbers due to misconfiguration.
• Users override automatic renaming, leading to inconsistencies.
• Copy Tree fails to apply serial numbers in the intended sequence.

Solution & Best Practices

• Check Serial Number Settings Before Running Copy Tree – Ensure that PDM is correctly configured to generate unique values.
• Manually Review Renaming in the Copy Tree Preview – Check for unintended duplicates before executing the copy process.
• Use Controlled Naming Schemes – Define serial number groups for different departments or projects to avoid conflicts.

2.4 PDM Vault Check-In/Check-Out Issues

Problems Where Copied Files Remain Checked Out to the Original User

A major frustration occurs when copied files remain checked out to the original owner, preventing other team members from editing them.

Why Does This Happen?

• Copy Tree does not automatically check in new files after copying.
• If the original files were checked out, their copies may inherit the same status.
• Users forget to manually check in files, leading to workflow delays.

Solution & Best Practices

• Enable "Check-in on Copy" in Copy Tree Options – This forces an automatic check-in after the copy process.
• Train Users to Manually Check-In Files Immediately After Copying – This prevents unintentional file locks.
• PDM Administrators Should Regularly Review Checked-Out Files – If necessary, force check-in of unused files.

Accidental Overwriting of Existing Versions If Naming Conventions Are Incorrect

If a copied file shares the same name as an existing file, it may overwrite the existing version without warning.

Solution & Best Practices

• Use Unique Prefixes or Suffixes to avoid name collisions.
• Configure PDM to Warn Users Before Overwriting Files.
• Enable Version History to Recover Overwritten Files if necessary.

Access Permission Errors Preventing Proper Check-In After Copy

• If a user lacks the correct folder permissions, they cannot check-in copied files.
• PDM might not recognize the copied files as new versions, preventing check-in.

Solution & Best Practices

• Ensure users have the right access levels in PDM before using Copy Tree.
• Use PDM Permission Reports to track who can check in files.

2.5 Network and Storage Issues

Copying Large Assemblies to a New Location Can Lead to Network Overload

Copying large datasets across a slow network can result in:

• Long wait times
• Failed copy operations
• Data corruption risks

Solution & Best Practices

• Use a 1 Gbps network or higher.
• Copy files during off-peak hours to reduce network congestion.
• Use PDM archive replication for multi-site vault setups.

Limited Storage Availability Can Cause Errors During Copy Tree Execution

• If the destination vault runs out of space, the copy process may fail.
• Some users may not have sufficient quota to store copies.

Solution & Best Practices

• Check available storage space before copying large files.
• Set up automated PDM alerts to monitor storage usage.

Firewall Restrictions Affecting File Transfers Between Vaults

• Firewalls may block Copy Tree from accessing remote PDM vaults.
• Network security policies may restrict file transfer speeds.

Solution & Best Practices

• Open required PDM network ports (3030, 1433, 1434, etc.) in the firewall.
• Use VPN tunneling to ensure secure data transfers.

2.6 Version Control and Audit Trail Challenges

Copy Tree Does Not Always Preserve Version History, Leading to Confusion

• When copying files, original version history is often lost.
• Users may mistakenly assume new copies contain previous revisions.

Solution & Best Practices

• Use PDM Labels to mark original files before copying.
• Enable PDM workflows to track file duplication events.

Issues with Tracking Modifications When Multiple Engineers Work on Copies

• If different engineers modify copied files, tracking changes becomes difficult.
• PDM’s history might not properly associate copies with the original project.

Solution & Best Practices

• Use "Where Used" in PDM to track copied file dependencies.
• Require users to log change notes in the check-in comments.

Compliance Risks If Previous Versions Are Lost or Not Properly Archived

• Some industries require traceability of all modifications.
• If Copy Tree does not preserve previous design iterations, companies may fail compliance audits.

Solution & Best Practices

• Enable PDM version rollback features.
• Maintain separate "historical archives" of key project files.

3.1 Optimizing Performance

Ensuring PDM Server Resources (RAM, CPU, Disk Space) Are Optimized

• Allocate sufficient memory to SQL Server for indexing operations.
• Use SSDs instead of HDDs for the PDM archive.

Running Copy Tree During Non-Peak Hours to Avoid Server Overload

• Schedule large copy operations for evenings or weekends.

Using Local Caching to Improve Copy Speed for Large Assemblies

• Enable PDM caching to reduce network transfer times.

3.2 Avoiding Reference Breaks

One of the most critical challenges when using Copy Tree in SOLIDWORKS PDM is ensuring that assembly references remain intact. If references break, it can lead to missing parts, misplaced drawings, or incorrect dependencies, causing major delays in project workflows.

Using Preserve Relative Paths to Maintain Assembly Structure

Preserve Relative Paths is a crucial setting in Copy Tree that ensures all file locations remain consistent relative to the top-level assembly. Without this, the copied assembly may fail to locate its referenced components, resulting in broken links.

How to Use Preserve Relative Paths in Copy Tree

1. Enable Preserve Relative Paths in the Copy Tree dialog.
2. Ensure that the copied files follow the same subfolder structure as the original project.
3. Verify that references update correctly within PDM before finalizing the copy process.

Common Issues Without Preserve Relative Paths

• Parts and subassemblies become unlinked, requiring manual reference fixing.

• Drawings lose their link to the models, causing missing views.
• BOM inconsistencies, leading to incorrect manufacturing data.

Best Practice: Always preview the reference structure in Copy Tree before executing the copy operation.

Checking Dependencies Before Copying to Avoid Missing Files

Before copying a project, it is essential to review all file dependencies to ensure nothing is left behind.

How to Check Dependencies in PDM

1. Open the SOLIDWORKS PDM Vault and navigate to the file.
2. Use the "Where Used" feature to see all linked dependencies.
3. Run a Reference Search in PDM to identify external file links.
4. Check for standard library components or shared parts that need to be included.

Why This is Important

• Prevents missing part files, reducing errors when opening assemblies.
• Ensures that external references are maintained properly.
• Avoids unexpected duplication of commonly used parts.

Best Practice: Use PDM Reference Search before copying files to confirm all required components are included.

Keeping a Backup of Original References in Case of Accidental Changes

Even with proper settings, accidental modifications can occur during Copy Tree operations. To avoid irreversible errors, maintaining a backup of the original references is crucial.

How to Create a Backup Before Using Copy Tree

1. Create a ZIP archive of the project folder before making copies.
2. Use PDM Version History to restore previous versions if needed.
3. Store a snapshot of file dependencies to compare post-copy reference integrity.

Best Practice: Always verify copied file references immediately after copying to catch any errors early.

3.3 Proper File Naming and Serial Number Strategies

Proper file naming is essential for maintaining an organized PDM vault and preventing conflicts when using Copy Tree.

Establishing Clear Naming Conventions Before Copying

A structured naming convention ensures consistency and prevents duplicate file conflicts.

Key Naming Rules for PDM

• Use standardized prefixes/suffixes (e.g., “RevA_” for revisions).
• Include project numbers in filenames for easy tracking.
• Ensure names do not exceed SOLIDWORKS character limits.

Using PDM Variables to Automate Serial Number Assignment

PDM can automatically generate serial numbers for copied files, eliminating manual renaming errors.

How to Automate Serial Numbering

1. Configure Serial Number Schemes in PDM Administration.
2. Assign unique number sequences based on part type (Assemblies, Drawings, etc.).
3. Enable automatic serial number regeneration in Copy Tree settings.

Benefits of Automated Serial Numbering

• Reduces human errors in file renaming.
• Prevents duplicate file names across the vault.
• Ensures unique identification for copied assemblies.

Running a Post-Copy Validation Check to Ensure Consistency

After copying files, perform a final validation check to confirm all files are correctly named and structured.

Key Steps in Post-Copy Validation

1. Use PDM Search to verify all renamed files.
2. Open the copied assembly in SOLIDWORKS to confirm references.
3. Check serial number integrity in the PDM Vault.

3.4 Managing Permissions and Vault Check-Ins

Proper user permissions and check-in procedures ensure that copied files do not cause conflicts in the vault.

Ensuring Proper User Access Settings Before Copying Files

PDM Admins must configure access permissions to ensure users can copy files without issues.

Best Practices for Managing Permissions

• Use Role-Based Access Control (RBAC) to assign permissions.
• Restrict unauthorized users from copying or renaming files.
• Enable logging for all Copy Tree operations.

Forcing Check-In Upon Copy to Prevent Lingering File Locks

A major issue in PDM is that copied files often remain checked out, preventing others from modifying them.

Solution: Enable Automatic Check-In

1. Select “Check-in on Copy” in Copy Tree settings.
2. Ensure users manually check in files immediately after copying.
3. Set up PDM notifications for pending check-ins.

Using PDM Logs and Audit Trails to Track Copied File Usage

Tracking copied files is essential for version control and compliance.

How to Use PDM Logs for Tracking

• Enable audit logging for all Copy Tree actions.
