What's new in KulmanLab — shipped continuously, no restart required.

Seven ways to draw an arc, plus new Polygon and ArrayPolar commands

2026.10.11.9025e98 October 11, 2026

Arc can now be drawn from its start, center and end, angle or chord length; from its start, end and angle, tangent direction or radius; or from its center first — with a clear message when a value makes no arc.
New Polygon command draws a regular polygon of 3 to 1024 sides from its center and radius, or from one edge; the Inside setting is remembered between runs.
New ArrayPolar command copies the selection round a center with a chosen number of items, angle and fill, and copies that turn as they go round or keep their own orientation. Both new commands have buttons, and the array commands sit in a dropdown under Edit.
Option keys such as Edge and Inside now work while a number is being typed. Failed saves, failed opens and each kind of terminal error are also reported to Sentry as separate issues, still without drawing content.

Clearer import and clipboard messages; hatch and multileader fixes

2026.10.08.cd1bea9d October 8, 2026

Import now says in the terminal what it could not read: skipped entities and tables are listed by type with a count, and an invalid file is named. Cancelling the file dialog now does nothing.
Clipboard messages now say why a copy or paste was refused and what to do about it — allow the clipboard in the browser's site settings. Pasting into text warns when the clipboard is refused.
Hatch finds a region's wall past whatever stands in it, fills past a fillet that touches a line it does not end on, and a hatch with no boundary is left out instead of saved.
A multileader's arrowhead is now taken from its style. The terminal's error lines are also included in the anonymous error reports.

Trim and Extend work with splines; a reworked Export Manager

2026.10.06.21167efe October 6, 2026

Trim now cuts splines — including where a spline crosses itself — and splines act as cutting edges for other entities. Each piece is the same curve over less of itself, with no refitting.
Extend now stops at splines, and hatches fill inside splines that cross themselves. What a trim will remove and what an extend will leave are highlighted in a solid accent stroke with a faint glow.
Export Manager reworked: the lists show only what the drawing contains, rows toggle as a whole, a second table chooses which text, leader and dimension styles are exported, and the footer counts the objects to be exported.
Errors are now also reported anonymously to Sentry — stack trace, app version and the app's own recent actions, never drawing content or personal data. Selecting an entity with thousands of points no longer freezes the page.

Named dimension styles, DXF fidelity, and text selection

2026.10.01.a0e1b5eb October 1, 2026

New DimensionStyle manager creates, duplicates, renames, deletes, previews, and selects the current named style for new linear, aligned, radius, diameter, and angular dimensions.
Dimension styles cover separate arrowheads, extension lines, center marks, text style and formatting, attachment, alignment, frames, and separate linear and angular precision.
DIMSTYLE import and export now preserve named styles and per-entity overrides; exported STYLE records use variable height so they cannot override a dimension style's text height.
Fixed framed dimension text, center marks, radius and outside-diameter arrow behavior, style fallback after opening a drawing, and added Ctrl/Cmd+A in the active text editor.

Czech and Lithuanian app interfaces

2026.09.29.6614ca27 September 29, 2026

The complete CAD interface, command names, prompts, and dialogs are now available in Czech and Lithuanian.

Named text and leader styles, with stronger AutoCAD DXF compatibility

2026.09.28.94a59e1a September 28, 2026

New TextStyle and LeaderStyle managers create, duplicate, rename, delete, preview, and select the current named style for new annotations.
Text styles now include font, positive height, bold, italic, line spacing, horizontal alignment, and frame defaults; new text copies the current style without staying live-linked.
MLEADERSTYLE now imports and exports with matching text-style references, and text attachment is written consistently for leaders on either side.
Fixed AutoCAD MTEXT frame export and polished both style dialogs with real-renderer previews, inline renaming, fit zoom, and safer handling of annotative styles.

Everything exports to DXF; Export Manager picks what goes in

2026.09.07.dd8ce99 September 7, 2026

DXF export is no longer geometry-only. Text, dimensions, leaders and hatches all go into the file now, so an annotated drawing arrives annotated instead of stripped back to bare lines.
Text exports as MTEXT and keeps its per-run formatting — font, height, bold, italic, underline and strikethrough.
Dimensions export as standard DIMENSION entities: linear, aligned, continued, radius, diameter and angular.
Leaders export as MULTILEADER, with the landing segment and text attachment written where other tools expect to find them.
Hatches export as HATCH, carrying the pattern name, scale, angle and origin. The resolved pattern lines go inline as well, so a tool that has never heard of your pattern still draws it correctly.
Export Manager rebuilt as a single list: every entity type in the drawing with its count beside it and an Include checkbox, plus a select-all. Untick Text, the dimension rows, Leaders and Hatches and what downloads is cut geometry and nothing else.
New: KulmanLab can be installed from the browser as an app.
Fixed: exports that other tools refused to open at all — exponential floats, a bad Defpoints plot flag and an empty arrowhead block. A single malformed entity no longer aborts the whole export either.
Fixed: a long list of round-trip bugs — dimension text height, position and font overrides, angular measured angle and arrow styles, and ellipses and hatches being rejected when their axis ratio came out above 1.

Type an exact distance from a pin, in every command

2026.08.31.e1747c7 August 31, 2026

New: direct distance entry. Lock the direction from a pin, type the distance, and the point lands exactly there — no dragging and no arithmetic.
It now covers essentially every command that asks for a point: Line, Polyline, Arc, Circle, Ellipse, Rectangle, both Spline modes, Area, Distance, Angle, Move, Copy, Rotate, Scale, Mirror, Align, Text, every dimension, Leader and ChangePrintArea.
Grip editing came along too — grab a grip, lock the direction, and type the exact displacement.
The Pins dropdown is now a plain Dist toggle beside it, and the ANGL and Pins arrows flip when their menus open.
New: copy and paste entities between browser tabs.
New: unused layers can be deleted.
New: the properties panel can auto-hide to the edge and slide back when you reach for it.
Fixed: layout paper sizing — viewport scale is normalised to millimetres per model unit, plot rotation is honoured, an unconfigured layout defaults to landscape, and a layout with no viewport gets one synthesized.
Fixed: hairline and default-weight lines printed too thick at lower DPI, and Print Manager silently dropped an entity that was perfectly axis-aligned.

Fillet for arcs & polylines; Export Manager redesign

2026.08.19.23a9785 August 19, 2026

Fillet now works on Arc and Polyline segments, not just Line — pick two and the corner rounds in place.
Filleting two separate polylines, or a polyline and a loose Line/Arc, now merges them into a single polyline.
New: Rectangle gains a Dimensions option — type D, enter a width and height, and it remembers them next time.
Export Manager redesigned as side-by-side JSON and DXF columns, each listing the entity types it carries.
Font+, Hatch+, Leader+ and Leader- are now FontAdd, HatchAdd, LeaderAdd and LeaderRemove; Lwpolyline is now Polyline.
New LayerManager command; Import, Font Manager, Hatch Manager and Page Setup now run as real commands.
Fixed: DXF export wrote color, linetype and lineweight out of position, and dropped an explicit hairline lineweight.
Fixed: Fillet no longer rounds an already-tangent polyline corner or sweeps the long way around an arc.

Polyline: Arc segments & Explode; Print Manager fixes and Blueprint style

2026.08.16.ae2fea1 August 16, 2026

New: Polyline gains an Arc option for placing arc segments while drawing (tangent-continuation by default) — Trim, Extend, Offset, Chamfer, and intersection detection are all arc-aware now, so editing a polyline with arc segments works the same as a straight one.
New Explode command breaks a polyline into its individual Line and Arc entities.
New: Rotate gains a Copy option — press C to toggle it, and the rotation is applied to new copies instead of the original in place.
New: Print Manager's Style selector gains a third option, Blueprint, alongside Default and Monochrome — white ink on a deep Prussian-blue page with a faint reference grid sized to look the same density at any Quality setting.
Fixed: Print Manager's preview now renders at the exact same pixel size as the real export instead of approximating it, and changing Quality re-renders it immediately; line weights now scale with print DPI instead of a fixed pixel count, so a line keeps the same physical thickness on paper at any Quality setting (hairline / lineweight 0 stays a fixed 1px, per the conventional hairline definition).
Fixed: a selected print area now actually crops layout (paper-space) exports instead of always exporting the whole sheet, including on a layout whose units aren't real mm; monochrome rendering now forces black ink at the source instead of thresholding pixel brightness afterward, removing an artifact that could double a thin line's apparent width.
Fixed two polyline-arc bugs found while building the Arc option: Trim could compute the arc immediately next to a cut backwards, and a clockwise arc segment could report intersections on the wrong ~300° span, trimming away far more of the polyline than intended.
Fixed: Chamfer's second pick on a polyline now requires a true neighboring segment instead of silently chamfering a non-adjacent pair; extending a polyline's first segment now grows from the correct end and direction.
Fixed: Backspace no longer deletes a selection while you're still typing a command.
Tuned command-suggestion tie-breaking so Extend ranks above Export and FileManager/Delete rank lower when they share a prefix with another command.

Command suggestions, selection filtering & finish-with-Enter polish

2026.08.13.1df92de August 13, 2026

Command suggestions now match letters anywhere in a command's name, not just the start, ranked by match quality and then by how often you actually use each command; the list is mouse-clickable, scrolls to keep the selected suggestion in view while cycling with Tab, caps around 10 rows, and highlights just the matched letters in place instead of overlaying a full ghost word
New: selecting many entities shows a filter icon in the property panel header — opens a popup with live checklists for Type, Layer, Color, Lineweight, and Linetype built from what's actually in the selection, so a large mixed pick can be narrowed down before bulk-editing
Space/Enter now finishes Hatch, Spline (CV and Fit), Offset, Trim, Extend, Area, and Align, matching how the rest of the app already worked; fixed a Trim bug where a full ellipse/circle cut's rounded stored angle could sit just outside a hatch's boundary tolerance and leave the traced loop unclosed
Monochrome print and export rendering is dramatically faster on large plots — replaced a per-shape canvas filter with a single pass over the finished image; a 90,000-entity file that previously wouldn't finish in 30 seconds now renders in about 70ms

Hatch: pick-a-region fill, pattern library & grip editing

2026.08.11.fa6fa31 August 11, 2026

New Hatch command — click inside any closed region (Lines, Arcs, Circles, Ellipses, and Polylines meeting at their ends all enclose one, just like a closed Lwpolyline) and it fills with a pattern; anything closed sitting inside is left alone as an island
Hatch stays active after filling one area, so a single activation fills as many regions as you like; Escape ends it
Pick a fill pattern from a swatch grid in the new Hatch Pattern picker — the built-in ANSI/ISO library plus SOLID — and manage it from Hatch Manager, where you can upload your own .pat files
HATCH entities in imported DXF files now render with their real pattern, scale, and angle instead of being skipped
Hatches are fully grip-editable — drag a corner or an edge's midpoint to reshape the boundary and the fill follows live; works on straight, arced, elliptical, and now spline edges, including islands
Fixed: resizing a hatched circle by its rim no longer drags the whole circle, mirroring a hatch keeps its boundary joined up, and a hatch pick that finds nothing now explains why in the command prompt
Richer property panel for hatches — pattern, scale, angle, and origin are all editable directly

Extend: Arc, Ellipse & Polyline support; redesigned File Manager

2026.08.07.ab0f344 August 7, 2026

Extend now works on Arc, Ellipse, and Polyline, not just Line
Ellipse/Ellipse intersections now detected (needed by Extend and Trim); Polyline/Polyline intersection cost bounded with a bounding-box reject so large drawings stay fast
File Manager redesigned as a thumbnail grid — click a thumbnail to open the file, confirm before deleting one, see a placeholder icon for files with no thumbnail yet, and page through large libraries
Rename files in place and reorder them; the currently open file is highlighted and can't be deleted from the list; the panel now closes automatically whenever a command starts or a file finishes loading
Thumbnails are generated directly from a file's stored entities and are crash-proof — one malformed entity no longer breaks the whole thumbnail
Keyboard shortcuts added for text editor formatting; Space now finishes a line chain, not just Enter
Fixed lineweight parsing and serialization, and DXF parsing for files with bare LF line endings and unpadded group codes
Removed the unused Google AdSense wiring and the Help panel's "Cookie settings" button (ads were never live)

Trim: Arc, Circle, Ellipse & Polyline support

2026.07.26.70984c6 July 26, 2026

Trim now works on Arc, Circle, Ellipse, and Polyline, not just Line — hover the segment between two intersection points and click to cut it, exactly like Line trimming already worked
Circle, Ellipse, and a closed Polyline (including Rectangle) have no natural start or end, so trimming one now requires at least two intersection points; the piece between whichever pair the cursor is nearest becomes the removed segment, and a Circle trims down into an Arc
Fixed several intersection bugs surfaced while building this: Line trim no longer deletes the whole line on a touching (non-crossing) intersection, Circle/Ellipse intersections no longer miss a point that lands exactly on the other shape's endpoint or drift after repeated trims, and Circle/Arc no longer trims straight through an Ellipse without leaving the gap
Ellipse previews for Mirror, Rotate, and Trim now render at the correct orientation instead of resetting to the un-rotated axis
Legacy DXF POLYLINE entities (the format that predates LWPOLYLINE) now import correctly, including malformed or mesh-style data that previously failed to parse
Shapes toolbar reordered (Ellipse, stacked Splines, Arc last), markup toolbar icons grouped by tool family, the Array button restored, and the Dimension Linear icon's grip/arrow sizing fixed

Text editor: paragraph alignment, underline & rotated-text fixes

2026.07.23.49fac9a July 23, 2026

New paragraph alignment buttons in the text editor toolbar — Align Left, Align Center, Align Right, and Justify — layered on top of the attachment-point column; available for Text entities only, not Multileader or dimension labels
New underline toggle button next to Bold, Italic, and Strikethrough
The text cursor now slants to match italic text while editing, matching word-processor convention
Fixed click-to-place-caret resolving to the wrong character on text rotated to any angle other than 0°/180°
Fixed the text editor popup floating over the text instead of above it for Middle/Bottom-anchored attachment points, and overlapping rotated leader text on Multileaders
Fixed per-character height overrides (e.g. mixed font sizes imported from DXF) keeping their absolute size instead of scaling with the entity, on both Text and Multileader

How-to guides (25 languages) & responsive nav polish

2026.07.19.b22f372 July 19, 2026

How-to guides and the site header now render cleanly on phones and tablets — the mobile menu includes the new How-to link alongside Docs, Changelog, and FAQ
New How-to page with 9 step-by-step guides — opening DXF files, drawing with exact dimensions, organizing layers, dimensioning, measuring distance/angle/area, preparing files for laser cutting or CNC, paper layouts with viewports, printing, and backing up drawings — translated into all 25 site languages
Fixed language switching on English pages: with a language saved in the dropdown, pages like Privacy and About now redirect to the fully translated version instead of staying in English with only the navigation labels swapped
Shortened overly long page titles (homepage and About page) in 20+ languages so they display fully in search results

Privacy policy, About page & GDPR-compliant consent banner

2026.07.15.0c09002 July 15, 2026

New Privacy Policy page explains what data KulmanLab collects — local-only drawing storage, Google Analytics, and the advertising coming to the app via Google AdSense — translated into all 25 site languages
New About page tells the story behind KulmanLab — translated into all 25 site languages
Added a region-scoped cookie consent banner using Google Consent Mode v2: Analytics defaults to denied until accepted in the EEA, UK, and Switzerland, and to granted immediately everywhere else; a "Cookie settings" link in the footer reopens it at any time
Footer trimmed to About, Privacy, Cookie settings, GitHub, and Reddit — App, Docs, Changelog, and FAQ remain one click away in the header
Fixed Google Analytics silently not recording custom events (Launch App clicks, outbound link clicks, scroll depth) on the live site — the tracking script was being scoped by the bundler so window.gtag never actually existed

Vector pins: object snap tracking with angle-lock ray snapping

2026.07.12.16f6fe3 July 12, 2026

New Vector Pins toggle (Pins) in the control bar — hover a snap point or grip for 500ms to pin it, then track the cursor along dashed horizontal/vertical reference lines through the pinned point, with normal geometry snaps still taking priority
Angle-locked rays now snap to the intersection of the locked direction with pin reference lines in Line, Polyline, Arc, Circle, Move, Copy, Area, Leader, and ViewportCopy
Distance and Angle now keep their result on screen until Escape, with an accent-colored preview that is dashed while picking and solid once committed; Distance also shows grips at both endpoints
Fixed a bug where clicking model entities visible through a layout viewport selected phantom paper-space copies whose edits and deletes silently did nothing — viewport content is now display-only for selection (snapping through viewports is unaffected)
Intersection X markers now draw in the accent color instead of green, matching the rest of the snap and preview palette
Improved the ANGL control-bar dropdown layout

Align command: translate, rotate & scale with point pairs

2026.07.09.cecea22 July 9, 2026

New Align command repositions entities using one or two pairs of source/destination points — translate only with one pair, or translate + rotate + optional scale with two
One-point alignment (press Enter at the second source point) works exactly like Move — translate only, no rotation
Two-point alignment computes the rotation from the source and destination segment directions, then prompts Yes/No to also scale so the segment lengths match
Live canvas preview at every step: a ghost move preview while placing the first destination point, then a dashed rotated preview once both destination points are set
Accessible via the new Align button in the Edit toolbar panel, or by typing `align` (as few as `al` is enough) in the terminal
Fixed Align prompt wording to match the "pick" phrasing used by other commands

Area measure command & toolbar icon refresh

2026.07.07.dca1eff July 7, 2026

New Area command measures the enclosed area and perimeter of a polygon — click 3 or more points, then press Enter to close the shape
Area supports angle-locked directional entry: snap to the configured angle-tracking increment and type an exact edge length
The closed polygon — fill, outline, and vertex grips — stays highlighted on the canvas until you dismiss the result
Measure panel is now a 2×2 grid: Distance and Angle on the top row, Area on the row below
Distance and Angle toolbar icons redrawn with solid strokes and a filled wedge instead of dashed lines
Area toolbar icon simplified to a chamfered square with vertex snap points
Fixed terminal prompt text jumping when the key badge appears

Text editor copy/paste, feedback bar & theme-aware arrowheads

2026.07.01.41031df July 1, 2026

Text editor: Ctrl/Cmd+C, Ctrl/Cmd+X, and Ctrl/Cmd+V now copy, cut, and paste the selected text
Pasted text always takes on the formatting already at the cursor rather than the formatting it had when copied; rich mode keeps line breaks, simple mode (dimension labels) strips them
New feedback bar in the toolbar links to Reddit, GitHub Issues, and email — appears after 10 minutes of use and can be dismissed
Arrowhead previews in the Properties panel and arrowhead picker now render in a theme-aware color instead of always white
Improved contrast for toolbar panel captions (e.g. "STYLE", "LAYERS") in light theme
Coordinate and zoom readout in the toolbar now sit closer to their labels instead of a fixed-width right-aligned column

Text editor modes: rich and simple

2026.06.28.8f3519f June 28, 2026

Text editor header now shows a mode chip — "rich" (accent color) for Text and Multileader, "simple" (muted) for dimension entities
Double-click any linear, aligned, angular, radius, or diameter dimension to open its label in the text editor
Simple mode: editor is pre-seeded with the current rendered label so you can position the cursor with ← / → and edit the value directly
Simple mode: pressing Enter commits the value and closes the editor — no line break is inserted
Simple mode: bold, italic, font, and height changes apply to the entire dimension label at once
Rich mode (Text, Multileader): per-character formatting, multi-line Enter, and word-wrap remain fully supported
Blinking cursor now animates inside the dimension text editor popup
Text cursor offset corrected — was rendering up to 2× too high after certain font changes
