When should I delete local Teamwork data in Archicad?

Description 

If you are working on Teamwork projects in Archicad, deleting local cache data can resolve various issues related to synchronization, performance, or file corruption. However, this action should be used with caution, as unsent changes will be permanently lost. 

Solution

Below are the scenarios when it is appropriate to delete local Teamwork data:

1. When Facing Teamwork Synchronization Issues

• Changes made by you or others are not visible after Send & Receive.
• Elements appear locked or reserved by another user, even when they shouldn’t be.

2. When Experiencing Performance Issues

• The Teamwork project is slow to load or navigate.
• Unexpected lag or freezes during Teamwork operations.

3. When Changes Are Not Saved Correctly

• Changes revert after performing Send & Receive.
• Elements or views you modified disappear or fail to update on the server.

4. When Display or Graphic Issues Occur

• Library objects appear as black dots.
• Elements are misrepresented or missing in your views but not for other users.

5. When Receiving Cache-Related Error Messages

Such as:

• "Incompatible or corrupted cache file."
• "Error during last Teamwork operation."
• "Cannot open ARCHICAD cache."

6. After Upgrading Archicad

When switching to a newer Archicad version and migrating the Teamwork project, clear any remaining cache from the previous version to avoid compatibility issues.
