What’s new in Altium Designer 25.8.1 Build 18?

(Released on 16-07-2025)

Schematic:

• In some cases when annotating schematics, an Access Violation (at address 00000001403B6B00 in module “WorkspaceManager.DLL”) would be encountered.
• In some cases, attempting to move a placed component off of a schematic sheet (beyond the sheet’s border) was not possible, depending on the rotation of the component.
• When attempting to multi-select a placed sheet symbol’s designator and file name, the error “Exception has been thrown by the target of an invocation…” would be encountered.

PCB:

• The violation overlay was not being displayed over solid polygon pours detected to be in violation of a ‘Modified Polygon’ design rule.
• When attempting to copy and paste formatted text from Microsoft Outlook/Word into a PCB document, an Access Violation (in module ‘ADVPCB.DLL’) would be encountered.
• When copying and pasting a via (without keeping the same net), the subsequent dialog with which to choose a net (to apply to the via) would freeze for a considerable length of time.
• When entering an expression into the Filter region of the PCB/PCBLIB Filter panel, the sorting of entries in a pop-up listing is now correctly sequential “1, 2, 3, 4, 5,…” instead of “1, 10, 2, 20, 21,…”.
• As part of the PCB.Performance.InteractivePropertyPanel.Optimization option (Advanced Settings), the Properties panel has been further enhanced when working with a selected Embedded Board Array object, to increase performance and optimize access to object properties, especially with larger designs.
• When generating IPC-2581 (revision B) fabrication output from a PCB, polygon cutouts placed on power plane layers were incorrectly interpreted and exported as solid copper regions.
• When generating IPC-2581 (revision B) fabrication output from a PCB, keepout regions placed on the Top and Bottom layers were incorrectly interpreted and exported as solid copper regions.
• Export of a PCB document to ‘Protel PCB 2.8 ASCII’ format was not working. The exported file contained no board data.
• As part of the PCB.Performance.InteractivePropertyPanel.Optimization option (Advanced Settings), the Properties panel has been further enhanced when working with PCB library properties (when no objects are selected), to increase performance and optimize access to properties, especially with larger designs.
• As part of the PCB.Performance.InteractivePropertyPanel.Optimization option (Advanced Settings), the Properties region of the Polygon Pour Manager dialog has been enhanced when working with a selected polygon pour, to increase performance and optimize access to properties, especially with larger designs.
• As part of the PCB.Performance.InteractivePropertyPanel.Optimization option (Advanced Settings), the Properties panel has been further enhanced when working with a selected OLE/connection line object, to increase performance and optimize access to object properties, especially with larger designs.
• The relative Delay for each type of primitive is now calculated and stored to cache, facilitating a performance boost in Delay calculation when reopening a design and selecting a primitive for the first time.
• When interactively routing a differential pair and switching from the current pad/track to the target pad/track (using the ‘9’ keyboard shortcut), an infinite-looping error “Second differential pair primitive could not be found” would be encountered.
• With the Trace Loop Removal feature enabled, routing from an existing track to an unconnected pad (of the same net) would incorrectly remove existing track-to-pad routing.
• The ‘QR and Data Matrix Code Support’ feature, delivered by the PCB.QRCodes option (Advanced Settings), is now officially made Public with this release (ON by default).
• The ‘Optimized Online DRC Processing’ feature, delivered by the PCB.DRC.OnlineOptimization option (Advanced Settings), is now officially made Public with this release (ON by default).
• Nets were not being included when exporting a PCB as a Specctra Design file.
• When attempting to fix a micro-segment issue through the PCB Health Check Monitor and the micro-segment has already been manually removed, the error “Object accessed after being destroyed…” would be encountered.
• Pads with different countersink and counterbore hole sizes were incorrectly assigned the same diameter tool in the PCB panel (in its Hole Size Editor mode) and in generated NC Drill output.
• With a Net Antennae rule scoping a specific net, the PCB Rules and Constraints Editor dialog’s ‘Test Queries’ feature erroneously reported zero applicable objects.

Constraint Manager:

• When defining constraints for a clearance rule, clearance values for Top Layer and Bottom Layer were incorrectly being inherited from Inner Layers instead of Outer Layers.
• When defining constraints for a clearance rule, custom clearance values set for Outer Layers were being reset to defaults when changes to values for Inner Layers were reset to their defaults.
• In some cases while working with the Constraint Manager, the error “System.NullReferenceException: Object reference not set to an instance of an object” would be encountered.
• In the All Rules view of the Constraint Manager (when accessed from the PCB), a warning and related highlighting has been added for a rule that contains a syntactically incorrect custom query expression and is therefore deemed invalid.
• After switching from the ‘Default Stack’ to a specific PCB and defining a clearance set, it was not possible to subsequently remove any assigned constraint sets. While they could be removed in-session, saving-closing-accessing the Constraint Manager would show them still present.

Draftsman:

• In some cases when working with a Draftsman document, the error “EOleException: Board not found” would be encountered.
• Row visibility settings for a placed transmission line table were incorrectly being changed when importing changes from the linked PCB document and also when generating PDF output through an OutJob file.

CAMtastic:

• For ODB++ fabrication output generated from a specific panelized board, some drill drawing data for the panel was not being presented in the CAMtastic document.

3D-MID Design:

• After initially importing components into a 3D-MID document (via ECO), attempting to move multiple selected components from free space onto the 3D substrate would result in an Access Violation (in module ‘A3dEntry.dll’) being encountered and, in some cases, forced closure of Altium Designer.
• The commands to ‘Show All’ and ‘Hide All’ net connection lines (on the View » Connections menu) were no longer working.

Multi-board Design:

• Added the ability to define an ‘Inline Harness Connector’ on a multi-board schematic, splitting an existing harness connection into two.
• In a specific case, attempting to remove an entry connected to a harness on a multi-board schematic document would result in the error “Object reference not set to an instance of an object” being encountered.

Harness Design:

• When placing a linear dimension between connection points on a layout drawing view placed in a Harness manufacturing drawing (*.HarDwf), the value used for the ‘Value’ field (the length of the dimension) is now automatically filled with the corresponding bundle length.
• In some cases after freely positioning/rotating designators and parameters in the layout drawing (with their ‘Autoposition’ option disabled), they would be rotated/moved after importing changes from the wiring diagram.
• In some cases when working with a harness design’s wiring diagram, the error “EOleException: One or more errors occurred. (Object reference not set to an instance of an object.)” would be encountered.
• Added full support for using Harness Wiring Templates (in a harness wiring diagram) and Harness Layout Templates (in a harness layout drawing), both local and Workspace-based, using the commands available from the respective editor’s main Design » Sheet Templates menu.

Platform:

• The command to access the Storage Manager was not always available from the right-click context menu for project documents in the Projects panel.
• When configuring synchronization options between schematics and PCB in the Differences between dialog, the ‘Update Same Kind in…’ commands were no longer functional.

Data Management:

• Where a reuse block placed on a schematic contained a component where a pin had been mapped to multiple footprint model pins (pads), the block was not transferred correctly from the schematic to the PCB.
• For a variant of a design using an alternate component, when attempting to update that alternate component to its latest revision, through the Item Manager, the wrong component (base, non-varied component) would be updated.
• When editing a Workspace component as a user with view-only permissions, the Component editor will now always open, giving you the ability to access component details and make local edits, but with the inability to save/release any changes back to the connected Workspace.
• When using a control to rename an entity anywhere in the software (e.g., a project or one of its documents), a couple of improvements have been made to the subsequent Rename dialog. Firstly, clicking OK without making a change to the current name will behave as though having clicked the Cancel button. The error “<Name> already exists” will no longer be encountered. Secondly, you can now change the case of characters in a name (e.g., renaming from ‘Myexamplepcb.PcbDoc’ to ‘MyExamplePCB.PcbDoc’).
• After renaming a Workspace project’s PCB document and at some later stage reverting back to a revision of the document prior to the renaming, a subsequent attempt to compare the local document against the head revision in the remote (Workspace’s Git) repository, would result in the error “Cannot find the common ancestor…” being encountered and data being lost.
• Added a notification for any issues relating to the WebSocket notification channel, when connected to a Workspace. Note that this notification appears only if the EDMS.ConnectivityMonitor option (Advanced Settings) is disabled. When this option is enabled, Altium Designer just disconnects from the Workspace when there is no Internet connection.
• With a variant selected in the Projects panel it was not possible, from the project’s ActiveBOM, to update an alternate part to its latest revision using the ‘Operations » Update to the Latest Revision’ command from the right-click context menu.

Import/Export:

• When importing a specific Allegro design, the solder and paste masks were missing for a few pads in the generated PCB document. (Requires the Importer.Allegro.ReadPadLayers advanced settings option to be enabled).
• When importing an OrCAD design with the ‘Convert Orcad Off-Page connectors as Altium Ports’ option enabled, a bidirectional off-sheet connector would be incorrectly imported as an ‘Unspecified’ port.
• In some cases when importing an OrCAD design, port names were being placed incorrectly on a generated schematic document.
• When exporting a PCB into Ansys EDB format, resistor values specified in MOhm were being incorrectly exported in mOhm.

Circuit Simulation:

• In some cases when working with the Mixed-signal Circuit Simulation feature, the error “EOleException: Could not find a part of the path “C:\ProgramData\Altium\Altium Designer {0E86C1C9-72CF-4BA0-A887-5B3AC0C1E1D4}\Extensions\Mixed Simulation\Library\SPICE models”” would be encountered.

SI Analyzer by Keysight:

• The SI Analyzer was not considering the Solder Mask in its calculations, when the ‘Use Solder Mask’ option was enabled as part of the Transmission Line properties for the Layer Stack Manager, leading to an incorrect impedance value when compared to that returned by the Layer Stack Manager (simulated by the Simbeor software).

System Requirements:

• Operating System: Windows 7/8/10
• RAM: 2 GB (4 GB recommended)
• Hard Disk Space: 200 MB or more
