What’s New

LinkCAD 11.1.8 (build 5101, 2026-10-26)

• FixCommand line: A session file passed with --config that names the input and output files and both formats now runs the conversion without a window when --quit is given. LinkCAD stopped at the format selection page instead.
• FixCommand line: LcApplyLayerMap=true and LcExitWhenFinished=true in a session file take effect. Unless the same option was also given on the command line, they were reset to false.
• FixCommand line: LinkCAD 10 session files whose LcSkipSteps lists every step run unattended and exit when done, as they did in LinkCAD 10. LinkCAD 11 converted the file but then stayed open.
• FixCommand line: LinkCAD 10 command lines work unchanged, including a value given as a separate argument (-LcApplyLayerMap true, -AnfOutMerge false), -i=file, and options LinkCAD 11 renamed (-LcCropX0).
• FixSessions: LcLoadDefaults=true, which every saved session starts with, resets the conversion settings to their defaults before the session is applied, as in LinkCAD 10, so a session reproduces the conversion it recorded; settings saved on exit keep the reset. The license, window layout, language and other application settings are kept. It did nothing before.
• FixSessions: Plugin options in a session file, such as PyPlugin.AsciiWriter.flatten, take effect. They were dropped, because the plugins had not registered them when the file was read.
• FixSessions: A session file that includes itself is reported as an error instead of crashing LinkCAD. A --config file that cannot be read is reported as an error instead of being ignored.
• FixBatch conversion: Converts the selected files again. After the export options, a batch ran on as a single-file conversion and never reached the batch tools or the conversion of the selected files.
• FixBatch conversion: A session with LcConvertBatch=true that skips the file selection (LcSkipSteps=all, or a list naming SelectImportFile) takes its files from LcImportFile, a folder or a pattern such as C:\layouts\*.gds, and runs unattended, as in LinkCAD 10. With Combine files and a format that reads several files into one drawing, they are converted together. A batch that finds no file, or fails to convert one, ends with an error; cancelling waits for the file being converted to stop, and so does closing the window.
• FixBatch conversion: Ticking Batch mode on the format page takes effect at once. Next went on to a single-file conversion until the page was left and entered again.
• FixBatch conversion: The batch is converted once. Two conversions of the same files ran side by side and could end LinkCAD.
• FixBatch conversion: File paths are shown with the separators of the operating system, \ on Windows.
• FixBatch conversion: The Batch Tools page has the same white background as the other wizard pages.
• FixBatch conversion: The Combine files setting is kept between runs. Every start of LinkCAD reset it.
• EnhancementANSYS ANF export: Job name, title and subtitle share one row of the options page.
• FixLinux: Session files written on Windows are read. Their Windows line endings made LinkCAD ignore the whole file.
• FixANSYS ANF and TETIN export: The default model units are micron again. With a new profile and no units given, the export failed with "Invalid Unit".

LinkCAD 11.1.7 (build 5100, 2026-10-20)

• FixLicense server: LinkCAD takes a network license when it starts, keeps it renewed while it runs, and returns it when it closes. It used to take one only when Test connection was pressed, and never renewed or returned it.
• EnhancementLicense server: When the server cannot be reached, LinkCAD keeps working through the grace period and takes a license again as soon as the server is back. The window and the License dialog show active, grace period and expired as they happen.
• FixLicense server: Test connection no longer takes a license of its own; it checks the license this computer already uses.
• EnhancementLicense server: A borrowed license replaces the network license while it lasts, and the network license is taken again when the borrow is returned or runs out. The server cannot be changed while a borrowed license is in use.
• FixLicense server: LinkCAD can use an on-premises license server. Test connection shows the server's ID and key fingerprint, to compare with the server's Settings page; once confirmed, LinkCAD trusts the server's licenses and its certificate, including the self-signed one a new server starts with. Before, every license from the server was refused, and a server with its first certificate could not be reached.
• EnhancementLicense server: Save for All Users stores the confirmed server key with the address, so every user of the computer trusts the same server without confirming it again.
• FixLicense server: A server that answers with a refusal, such as no license free or this computer not allowed, is reported as a refusal. It was reported as a network problem.

LinkCAD 11.1.6 (build 5099, 2026-10-20)

• EnhancementHelp menu: Shorter, with eight entries. Contact Support replaces Send Diagnostic Report and Email Support: it attaches a diagnostic snapshot, can save that snapshot to a file, and offers to email support instead, keeping the description you typed. Legal Notices is a button in the About box, and Getting Started is on the first-run card.
• EnhancementCommand line: --license-info reports the days left of a trial as trial_days_remaining.
• FixWindows: A program started from an administrator account with reduced rights, for example with runas /trustlevel, is offered the elevation prompt to save the trial license. It failed to save the trial without asking.

LinkCAD 11.1.5 (build 5098, 2026-10-19)

• FixWindows: The installer creates the trial license again. A user without administrator rights who started LinkCAD 11 for the first time got no trial and every module reported as not licensed.
• FixWindows: When the trial license cannot be saved, the license dialog says so and how to fix it, instead of reporting an expired license.

LinkCAD 11.1.4 (build 5096, 2026-10-09)

• EnhancementFirst-run card: The guided tour is now the primary choice, and trying the sample file on your own is the secondary one.

LinkCAD 11.1.3 (build 5095, 2026-10-04)

• FixLinux: Text in a font that is not installed, including the default TXT font and SHX fonts such as roman or simplex, is drawn in the TXT stroke font, as on Windows. It was drawn in whatever system font Linux offered for the name.
• FixLinux: The TXT stroke font is installed with LinkCAD.

LinkCAD 11.1.2 (build 5094, 2026-10-03)

• FixViewer: Click anywhere on a text to select it, between its letters included. Only a click on a stroke selected it before, and a rotated text is now picked by its own outline rather than the larger box around it.
• FixViewer: Text in a TrueType font, such as Arial, is drawn as filled letters with open counters. It was drawn as hollow, doubled outlines.
• FixViewer: The Bounds Width and Bounds Height in the properties panel follow an edit at once. They kept their old values until the selection changed.
• FixLinux: The letters of a TrueType text are spaced as the font defines. They were all drawn on top of the first letter.
• EnhancementExport: Formats without text of their own, such as CIF and Gerber, write TrueType text as filled letter shapes instead of outlined strokes.
• IE3D: The IE3D (.geo) import and export formats are no longer included.
• FixWindows: The installer's signature includes the SSL.com intermediate certificate, so Windows can verify the publisher without fetching it.

LinkCAD 11.1.1 (build 5093, 2026-10-01)

• EnhancementFirst run: A "New to LinkCAD?" card on the first page offers a sample conversion, the Getting Started guide and the documentation, and each later step shows a short hint the first time it appears. Tools > Options > General turns the hints off, or shows them all again.
• EnhancementA sample drawing, an SRAM macro from the GlobalFoundries 180nm open source PDK, is installed in the samples folder. "Try with a sample file" converts it from GDSII to DXF without asking for an input file.
• EnhancementHelp > Getting Started opens the guide that walks through a first conversion.
• EnhancementGuided tour: Help > Guided Tour, or Guided tour on the first-run card, converts the sample with each step pointed out on screen. It moves on only when you do what the step asks, and Escape or Skip tour ends it.
• FixTools > Options > General > Show tooltips now turns tooltips off. The setting was saved but had no effect.
• FixThe Structure and Viewer buttons on the File Structure page are shown in the selected language.

LinkCAD 11.0.39 (build 5090, 2026-09-25)

• FixLinux: Install and run on RHEL, Rocky and AlmaLinux 8 and later, Ubuntu 20.04 and later, and Debian 11 and later. The 11.0.38 packages required glibc 2.39 and installed only on the newest distributions.
• FixLinux: Python scripts run from the installed package. The embedded interpreter looked for its standard library on the build machine and failed to start.
• FixLinux: Command-line and scripted conversions run on a machine with no display, using the offscreen platform when no X11 or Wayland display is available.
• EnhancementLinux: The .tar.gz archive lists the system packages it needs and includes check-runtime-deps.sh, which names any that are missing. The .deb and .rpm packages depend on CA certificates.
• FixGerber Import: Import Gerber files on Linux, where every import failed. File names with non-ASCII characters are matched to their aperture lists on every platform.
• FixPolygons: Report the correct area for very large polygons, which came out as a large negative number.
• EnhancementLicensing: An expired trial or lease opens and displays files. Saving, exporting and batch conversion stay unavailable until the licence is renewed.
• FixLicensing: A computer keeps one identity whichever user runs LinkCAD, and a normal user on a virtual machine can use a trial or licence.
• FixLicensing: A time-limited licence or trial is not revived by setting the system clock back.
• FixLicensing: The trial request and the licence dialog tell a connection problem apart from a refused request, and a licence server error from both.
• FixLicensing: --license-info shows the licence's real expiry instead of PERMANENT when no usable licence is held, and reports the licence as blocked when the licence client cannot start.
• FixLicensing: Python scripts follow the same licence rules as command-line conversions.

LinkCAD 11.0.38 (build 5089, 2026-09-24)

• Version numbering: the LinkCAD 11 line remains in beta and continues at 11.0.x. Version 11.2.1, released on 10 August 2026, was numbered in error; its download remains available and nothing after it uses the 11.1 or 11.2 numbers. Version 11.0.37 was not released; its changes are listed here.
• Plug-in API: layer and data type numbers are now 64-bit. Native C++ plug-ins built for an earlier version must be rebuilt; Rust plug-ins are not affected.
• EnhancementOASIS: Keep layer and data type numbers up to 64 bits wide. Numbers above 2147483647 were refused, and some larger ones were imported onto layer 0.
• FixLayers: Report an out-of-range data type with the data type's own limits, instead of the layer number's.
• FixLicensing: Accept a legacy registration code installed from the command line. A valid code was rejected as invalid.
• FixLicensing: Reach the elevated licence storage service on every launch, and from the command-line licence commands. Both fell back to the non-elevated writer after an error.
• FixLicensing: Write the backup licence file under its proper name. It could be written to a file named after an error message, leaving stray files in the program data folder.
• EnhancementLicensing: --license-info reports the machine's serial number and legacy serial number, gives the licence expiry as a date, and exits with an error on an unlicensed machine under either licence system.
• EnhancementLinux: .deb, .rpm and .tar.gz packages are published with this release. They include every library LinkCAD needs, and the .deb and .rpm install a linkcad command on the PATH.
• FixInstaller: Sign LinkCAD's Python modules. They were installed unsigned.
• FixFrench: The GDS-TXT scaling field's keyboard shortcut no longer opens the Edition menu.
• FixOASIS Import: Read the database unit declared in the file. Drawings previously imported at the wrong size unless the file used the default grid.
• FixOASIS Import: Correct the decoding of signed integers, point lists, deltas and repetitions, so files written by other tools are read faithfully.
• FixOASIS Import: Correct placement mirroring, trapezoid and 45-degree trapezoid shapes, and path end caps.
• FixOASIS Import: Report a malformed file instead of continuing with partial data.
• FixOASIS Export: Produce files other tools accept. The end record, the database unit and the validation signature were all written incorrectly.
• FixOASIS Export: Keep shapes that were silently dropped, including paths and cells reachable only by reference.
• EnhancementOASIS Export: Add compressed blocks, validation signatures, repetitions for arrays, and strict mode.
• EnhancementOASIS: Expose every import and export option on the command line.
• EnhancementExport: Write every top-level cell for formats that can hold more than one. Only the main cell was written before.
• EnhancementLayer Map: Match a bare layer number against every data type of that layer.
• FixGDSII: Keep an empty text label, and keep layer numbers above 32767 on both import and export.
• FixLayers: Keep a layer's numbers when it is renamed. Renaming a layer could renumber it.
• FixMessages: Substitute values that were left out of several diagnostics, which showed a placeholder or another value in their place.
• FixConversion: Say when a file contained only empty cells and which option removed them, instead of reporting that it had no cells.

LinkCAD 10.4.1 (build 5049, 2026-09-03)

• FixODB++ Import: Restore the Gerber import options the nested Gerber read borrows. "Apply layer polarities" was left holding whatever "support D99" was set to, and D99 itself was never restored; both are remembered between sessions
• FixODB++ Export: Put back the GDSII Cadista compatibility setting rather than turning it off, so a later GDSII export in the same session is written as the user asked

LinkCAD 10.4.0 (build 5048, 2026-09-03)

• FixGerber Import: Apply level polarity when reading a file, so a clear level erases what the levels before it drew instead of coming in as an ordinary positive layer. Levels stay separate unless "merge all layers on import" is selected
• FixGerber Import: Compose the polarity runs of a file as one chain rather than one chain per level, so a clearance erases the material it covers even when it was declared under a different level name
• FixGerber Import: Skip the composition when the export format carries layer polarity within a single image, which is Gerber written as one file. The levels and their polarity commands then reach the output as they stood, and the drawing keeps the step-and-repeat blocks that the composition would have flattened
• FixGerber Import: Reduce the polarity runs in one indexed pass instead of a Boolean per run over the whole accumulated layer; the chained form is quadratic in the number of runs and a large photomask did not finish in four hours
• FixGerber Import: Carry the flash and fill-polygon flags onto the composed layer, which had none of them, so the Gerber writer stroked the composed contours instead of filling them
• FixGerber Import: Invert a negative image once for the whole file rather than once per level. Two levels of a negative image each inverted against the drawing bounds left the bounds whole
• FixGerber Export: Clear only the part of a polygon's hole that the polygons already written do not cover. A hole is written as a clear region, so where two polygons on one layer overlapped and the lower one had a hole, the hole took material out of the covering polygon as well
• FixGerber Export: Write a clearance whole and report how many, rather than abandoning the export, when the Boolean that trims it fails
• FixGerber Export: Erase a polygon's holes with clear polarity instead of splitting the polygon into abutting pieces; the splits ran straight through solid areas and left lines that viewers draw across the image. Polygons are now written largest first, so a clearance never erases a shape lying inside it
• FixGerber Export: Write every flash, stroke and arc after the region clearances rather than as it arrives. Only the polygons were held back, so anything else lying inside a hole was written first and then erased by the clearance
• FixGerber Export: Keep filtering degenerate region contours when the region also contains a circular arc; an arc used to flush the buffer and switch the filter off for the rest of the region

LinkCAD 11.0.34 (build 5086, 2026-09-02)

• FixGerber Export: Clear only the part of a polygon's hole that the polygons already written do not cover. A hole is written as a clear region, so where two polygons on one layer overlapped and the lower one had a hole, the hole took material out of the covering polygon as well
• FixGerber Export: Write a clearance whole and report it when the Boolean that trims it fails, rather than abandoning the export

LinkCAD 11.0.33 (build 5086, 2026-08-25)

• FixGerber Import: Apply level polarity when reading a file, so a clear level erases what the levels before it drew instead of coming in as an ordinary positive layer. Each %LN% level still becomes its own layer
• FixGerber Import: Compose the polarity of a file as one chain rather than one chain per level, so a clearance erases the material it covers even when it was declared under a different level name. Composing each level on its own dropped any such clearance
• FixGerber Import: Keep the level polarity for export only when the output can express it. Polarity is relative to one image, so writing every layer to a file of its own cannot carry it: a clear layer alone in a file erases nothing, and the clearance was lost
• FixGerber Import: Fixed a crash when reading a set of Gerber files in which one holds nothing but a clear level
• FixGerber Import: Invert a negative image once for the whole file rather than once per level. Two levels of a negative image each inverted against the drawing bounds left the bounds whole, because what one level did not paint the other one did not either
• FixGerber Import: Carry the flash and fill-polygon settings onto the composed layer, which had none of them, so the Gerber writer stroked the composed contours instead of filling them
• FixGerber Import: Removed the "merge all levels into one layer" option. Level polarity is now always applied, so the option no longer changed the image, and the layer map already merges layers
• FixGerber Import: Compose the level polarities of a large file in minutes rather than tens of minutes. A photomask that took over 45 minutes and 2.4 GB now imports in under 4 minutes and 1.5 GB
• FixGerber Export: Erase a polygon's holes with clear polarity instead of splitting the polygon into abutting pieces; the splits ran straight through solid areas and left lines that viewers draw across the image. Polygons are now written largest first, so a clearance never erases a shape lying inside it
• FixGerber Export: Write every flash, stroke and arc after the region clearances rather than as it arrives. Only the polygons were held back, so anything else lying inside a hole was written first and then erased by the clearance, and the output lost material the source has

LinkCAD 11.0.32 (build 5085, 2026-08-14)

• FixGerber Export: Always open region contours with an explicit D02; the move was dropped when a contour started at the previous region's end point, producing invalid Gerber that some viewers stroke as stray lines

LinkCAD 10.3.9 (build 5047, 2026-08-14)

• FixGerber Export: Always open region contours with an explicit D02; the move was dropped when a contour started at the previous region's end point, producing invalid Gerber that some viewers stroke as stray lines

LinkCAD 11.0.31 (build 5083, 2026-08-10)

• EnhancementEditor: Interactive drawing tools in the viewer — rectangle, polygon, polyline, circle and text, with rubber-band previews, vertex snapping and orthogonal (Shift) constraints
• EnhancementEditor: Cell authoring — create empty cells, convert the selection into a new cell, and place cell references with rotation, mirroring, magnification and array parameters

• EnhancementEditor: New Draw menu and viewer toolbar buttons with a current-layer selector for new geometry (requires Edit license)
• FixGerber Export: Stop writing stray hairlines where geometry finer than the coordinate format collapsed onto the output grid, and warn when such features are dropped

• FixTools: Fix arc detection for fully circular arcs
• FixTools: Fix QuasiCircleToCircleTask incorrectly converting elongated rectangles to circles by adding edge midpoint uniformity check; rejects polygons whose edge midpoints are not equidistant from the fitted center

LinkCAD 10.3.6 (build 5044, 2026-06-02)

• FixTools: Fix QuasiCircleToCircleTask producing wildly incorrect circles from arc-fragment polygons after de-embedding; add angular span check to reject polygons not covering at least 270° of the fitted circle, and fix dead-code maxError tolerance calculation
• FixGDSII Export: Fix potential dead-lock when splitting large polygons

LinkCAD 11.0.12 (build 5065, 2026-05-20)

• FixViewer: Fixed UI freeze when opening or processing large drawings with many polygon shapes
• EnhancementODB++: Implement ODB++ font support, step and layer selection, faster compression
• FixODB++: Resolve layer polarity by Boolean-composing positive and negative feature runs in source order
