Problem

After upgrading to a new year version of CAMworks or SOLIDWORKS CAM, users may experience the following error: "Problem in notification of part sel change".

There are 3 common causes for this issue:

1. TechDB.cwdb file selected is not compatible.
2. TechDB.cwdb file is inaccessible.
3. TechDB.cwdb file is corrupted.

Solution 1: File not compatible

In every new year version new parameters and entries are added to the Technology Database application and database file. Because of this, the previously used TechDB.CWDB file should not be linked immediately in the Technology Database application. Instead, we will need to Import it. The import process will update the database file with the additional entries and make it compatible with the current software version. If the TechDB.cwdb file is stored on a on a network shared drive for other users to access then the file must be imported first to update it before putting that file back on the network shared drive. Follow the steps below to import the TechDB:

1. Open the SQLite version of SOLIDWORKS CAM 20XX Technology Database or CAMWorks 20XX Technology Database.
2. Go to the Settings tab
3. Select "Import Database"
4. Select "Browse" to select the techdb.mdb file
5. Choose the Data to import and select "Import"

Solution 2: File inaccessible

If a TechDB.CWDB file is known to be up to date and compatible with the current software version, but we receive the error message then the file path for the database should be verified and updated if necessary. Reselecting the correct TechDB.CWDB in the Link Database section in the Settings menu of the Technology database application will update the file path. If the file is functional, then we will see a green box appear in the upper right hand corner of the Technology database application indicating that the link was successfully updated.

Solution 3: File corrupted

If both linking and importing a TechDB.CWDB file results in a RED message window in the upper right corner of the Technology database application then the file selected is either incorrect or damaged. To confirm the integrity of the file, test the file on a different machine or submit a support ticket with Hawk Ridge Systems so we can inspect the file.

For additional support, existing customers can submit a ticket or new customers can contact Hawk Ridge Systems.
