CAD plugin version: 25.11.0.0008

General

• Added support for PTC Creo 12 files in the Generic Plugin.
• Added records of raising and removing BOM edit locks on a parent item to the child item's history.
• Added a 'Cancel Checkout' record to the item history for drawing files.
• When viewing the Change Requests table, only the first 200 CRs in the table will show a thumbnail. For every CR, thumbnails will always be shown when selecting the CR to view its details.
• The eBOM section of an item's Where Used section now shows a maximum of 3000 elements. If there are more elements, you will see a warning.
• Fixed an issue where the Edit lock persisted after a check in on items with two drawings.
• Fixed an issue where documents with a custom specification type were not loaded in the item document section on the first attempt.

Plugins

CAD

• CAD plugin backup folders are now always created in the home folder.

October 6, 2025

CAD plugin version: 25.10.0.0004

Plugins

CAD

• Added support for Inventor 2026.
• Improved the check in process so that it stops if saving the file after updating custom properties fails.

General

• Optimized the Project management dashboard when loading on projects with large data.
• Added a Checkin without changes record to the item history to indicate when no changes were detected and therefore the CAD file version was not incremented during a check in of the parent item.
• Fixed an issue where an invalid sequence number was shown for the Effective Date of the item in the BOM tree.
• Fixed minor web application UI issues.
• Fixed performance issues related to the Project management dashboard.
• Fixed an issue where it was possible to modify published DMS documents.

API

• Implemented an API for deleting projects: /project/v2/projects/{projectId}/delete. This API is available to Tenant Admins and deletes project numbers, user-project relationships, and project business processes. Items and documents are no longer associated with the deleted project. This means they may be orphaned, or be associated with other projects.

September 24, 2025

Administration

• Tenant Admins may now export a history of all tenant property changes. On the Administration page, click your profile menu in the bottom-left corner and select Export history. Learn more.

September 8, 2025

CAD plugin version: 25.9.0.0006

Plugins

CAD

• You may now set the Release Type (Major or Minor) in the CAD plugin. This enables you to set this value prior to sending an item to a change request.

Administration

• Tenant Admins may now clear the edit lock on a change notice.
• Fixed an issue where exporting a workflow from one tenant and importing it into another resulted in errors when each tenant had teams of the same name.
• Fixed a number of issues related to clearing multiple locks on items.

General

• Fixed an issue where the Change Request Details Report was including the wrong division information.
• The 'Manufacturer Item Description' attribute is now included when exporting the BOM using the Export BOM and Export flat BOM functions.
• Security updates.

August 18, 2025

Administration

• Tenant Admins may now use the tenant property title.block.font.override to define a font to use when converting drawing attributes codes directly in the PDF. This property only works when the tenant property drawing.populate.original.pdf is enabled. Learn more.

August 11, 2025

CAD plugin version: v25.8.0.0003

General

• You are now able to see the lock-clearing actions in the item history.
• Custom attributes of types Integer and Decimal now support negative values.

Plugins

• Fixed an issue where it was possible to use 'Replace Component' on a child item when the parent item was locked by a different user. Now, the 'Replace component' action is no longer shown when the parent assembly is checked out by another user. Note that this only applies to the first-level children; deeper-level children are not in a direct eBOM relationship with the locked parent item and therefore can be replaced.

API

• Created a new API for changing item numbers /api/bom/v1/part_number/rename. This API checks if the new part number exists, and as long as it doesn't then it updates the part master and all part versions with the new part number. This change is recorded in the item history on each item version. This endpoint is available only to Tenant Admins.

Administration

• Added a new tenant property drawing.populate.original.pdf under drawing.populate.title.block.codes to manage how title blocks are updated on PFD translations. When enabled, the drawing codes are converted directly on the PDF, which means the released PDF is identical to the original PDF translation. When disabled, the drawing codes are converted on the DWG before saving it to a PDF, which means the released PDF may differ from the original PDF.
• Tenant Admins now have additional picklists to manage including: ITEM.BOM_UOM, ITEM.TYPE, and WORKODER.STATUS. You may add values to existing picklists but may not remove or modify existing values.

July 14, 2025

CAD plugin version: v25.7.0.0006

General

• Tenant Admins are now able to delete translations from item versions regardless of item status. Learn more.
• Introduced a security limit for generating BOM reports and creating projects. You are now restricted to generating a maximum of 30 BOM reports and 30 projects per minute.
• Fixed an issue where Published documents reverted unexpectedly to Draft.
• Fixed an issue where purchased parts could not be downloaded from the advanced search in the plugin.

Workflows

• Fixed an issue where the Discard button was not shown on change notices for Tenant Admins when the 'Allow Workflow Cancellation' field was unchecked in the CN workflow configuration.

July 10, 2025

• Restricted characters \/:*?\"<>| in item names are now replaced with an underscore ( _ ) in folder names created during bulk export.
• Tenant Admins may now delete item versions even if they do not have attached CAD files. This removes the previous limitation that required CAD files to be attached to delete items.
• Tenant admins are now able to delete items with configurations. Learn more.
• The API for deleting items DELETE /v1/items/{itemId} has been upgraded to support deleting items with configurations.

June 30, 2025

• You are now able to export a flat BOM of an item in an Excel file by selecting More Actions > Export > Export flat BOM. The report aggregates identical items into one row, where the quantity attribute is calculated based on the parent quantities. All item attributes are populated for each item, excluding any eBOM item properties. Learn more.
• Added a validation on the web application to check that you have the latest version of the eBOM loaded before you are able to modify eBOM attributes.
• Improved the error message so that it now clearly indicates when multiple ongoing change notices (CNs) involve the same item.
• Item BOM sequence in change notices now matches the BOM structure.

Administration

• Tenant Admins are now able to regenerate DWG and PDF translations on released items. This option is accessed for an item in More options > Admin > Regenerate Translation. To enable this option, the tenant property drawing.populate.title.block.code should be enabled. Learn more.
• Tenant properties previously hidden from Tenant Admins are now visible providing more control over your tenant without the need to contact Autodesk Support. Learn more.
• Tenant Admins are now able to clear eBOM structural locks in addition to the existing lock types, provided the item is not part of any active change request. Learn more.
• For security measures, the tenant property license.key.sw.doc.mgr has been removed from Administration, and cannot be fetched from API either.

APIs

• Enhanced permission checks for API endpoint api/division/v1/divisions. Now, only Tenant Admins can create new divisions using this API.

June 12 2025

General

• Updated the APIs /v1/items/{itemId}/files/{fileId}/versions and /v1/items/{itemId}/files/{fileId}/versions/{fileVersionId} to support deleting translations regardless of the item's status. This change can only be performed by Tenant Admins and is written to the item's history.

• Restricted users can no longer see projects they are not part of in the Where Used section of an item's details.
• Fixed an issue where the Reject button on investigation requests in the web app was missing, preventing you from rejecting IRs even though the "Allow Workflow Cancellation" option was enabled in the workflow settings.
• Documents that exist in categories marked as unchangeable on released items can no longer be moved.
• Fixed an issue that prevented you from setting the Out-Of-Office date to the following year.

Administration

This API can only be called by Tenant Admins and this action is documented in the activity stream.
• Added a new endpoint POST /api/bom/v1/parts/versions, which receives the part number parameter in the request body. That way, part numbers can now contain special characters. This endpoint functions the same as GET /api/bom/v1/parts/{partnumber}/versions, but the only difference is that it takes the part number from the request body.

General

• Enabled the option to sort by Creation Date for Quick Search results under the BOM section in the web app.
