GRASP 1.9.0

Learning GRASP

• The new user manual teaches the essential drawing, measuring, labelling, saving, and sharing workflows with illustrated examples.
• The Help menu opens the manual from the desktop and mobile web apps.

Landing Page

• Interactive demonstrations show geometric construction, measurement, and scripting in action.
• The demonstrations and controls fit narrow mobile screens without horizontal scrolling.

GRASP 1.8.0

Hover previews

• Preview palette styling, visibility controls, marking and measurement settings, and menu transforms before clicking.
• New constructions appear as translucent ghosts, and drawing tools preview snapped points, side marks, and full rays or lines.

Captions and calculations

• Format caption text and linked measurements together, insert common notation directly from the palette, and navigate growing fractions with Tab and arrow keys.
• Set independent units and rounding for measurements and caption links, and show a calculation link as its answer or full equation.
• Insert geometry-based measurement references into Calculate by clicking the figure.

Selection and angles

• Toggle objects and labels independently, select both with a box, and move selected labels together.
• Trace between straight arms at an existing vertex to choose the smaller or reflex angle, including rays, lines, and constructed paths.

GRASP 1.7.1

Changes

• Added macOS support for Apple Silicon and Intel Macs, plus Linux AppImage and Debian packages
• Added installation guidance for Windows and macOS security prompts
• Improved script errors with the failed line, command, and guidance on how to fix them

GRASP 1.7.0

Desktop platforms

• GRASP now runs on macOS, with one app for Apple Silicon and Intel Macs, and on Linux through AppImage and Debian packages.
• The installation guide explains first-open security prompts on Windows and macOS.

Script feedback

• Script errors identify the failed line and command, with guidance on how to fix them.

Dialog layout

• Dialogs stay within the window, including on smaller screens.

GRASP 1.6.0

Cursors

• Every tool's cursor is an arrow in that tool's colour, with the tool's own glyph beside it, and it clicks at the arrow's tip.
• The cursor is no longer cut off near the edge of the sheet.
• In an embedded sketch, the cursor no longer sticks in place when the page around it is scrolled.

Toolbox

• The Arrow's Points, Paths, Markings and Text keys show the cursor each one gives you.
• The relabel key shows the letters a run hands out.

Website

• The landing page opens with a triangle's incircle being constructed. Where a reader has asked their system for less motion, it shows a still instead.

GRASP 1.5.0

Cursors and tooltips

• Each tool has its own cursor, its icon in its colour, visible on any paper or figure.
• The Arrow's cursor shows a badge for what it will pick up.
• Tooltips appear instantly, name the shortcut, and show on greyed out keys.

Drawing and measuring

• New Regular polygon tool: pick the shape or type the number of sides, and say whether it stays regular when dragged.
• A measurement's number can be linked to the figure it reads, so it moves with the drawing.
• Dragging a point on a path pulls the path's loose end along. Dragging the path leaves the point where it was.

Naming

• A figure stays unnamed until you ask for labels. The labels panel lists only what is named.
• Use the new relabel tool to label vertices with consecutive alphabets starting with your choice.
