Changelog

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

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
