Changelog

2.x

Bug fixes:

  • Do not crash when changing an unconstrained lathe group between union and difference modes.

2.3

Bug fixes:

  • Do not crash when applying a symmetry constraint to two points.
  • Fix TTF font metrics again (properly this time).
  • Fix the "draw back faces in red" option.
  • Fix export of wireframe as 3D DXF.
  • Various minor crashes.

2.2

Other new features:

  • OS X: support 3Dconnexion devices (SpaceMouse, SpaceNavigator, etc).
  • GTK: files with uppercase extensions can be opened.

Bug fixes:

  • Do not remove autosaves after successfully opening a file, preventing data loss in case of two abnormal terminations in a row.
  • Do not crash when changing autosave interval.
  • Unbreak the "Show degrees of freedom" command.
  • Three.js: correctly respond to controls when browser zoom is used.
  • OS X: do not completely hide main window when defocused.
  • GTK: unbreak 3Dconnexion support.
  • When pasting transformed entities, multiply constraint values by scale.
  • Fix TTF font metrics (restore the behavior from version 2.0).
  • Forcibly show the current group once we start a drawing operation.
  • DXF export: always declare layers before using them.
  • Do not truncate operations on selections to first 32 selected entities.
  • Translate and rotate groups inherit the "suppress solid model" setting.
  • DXF: files with paths containing non-ASCII or spaces can be exported or imported.
  • Significantly improved performance when dragging an entity.
  • Various crashes and minor glitches.

2.1

New sketch features:

  • Lathe groups create circle and face entities.
  • New toolbar button for creating lathe groups.
  • Chord tolerance is separated into two: display chord tolerance (specified in percents, relative to model bounding box), and export chord tolerance (specified in millimeters as absolute value).
  • Bezier spline points can be added and removed after the spline is created.
  • When an unconstrained extrusion is switched between "union" and "difference", its normal is flipped.
  • Groups can be added in the middle of the stack. Note that this results in files incompatible with version 2.0.
  • Active group can be removed.
  • Removing an imported group does not cause all subsequent groups to also be removed.
  • When a new group with a solid is created, the color is taken from a previous group with a solid, if any.
  • Entities in a newly active group do not become visible.
  • When entities are selected, "Zoom to fit" zooms to fit only these entities and not the entire sketch.
  • Zero-length edges are reported with a "zero-length error", not "points not all coplanar".

New constraint features:

  • Height of the font used for drawing constraint labels can be changed.
  • New constraint, length difference, placed with J. (Patch by Peter Ruevski)
  • Horizontal/vertical constraints are automatically added if a line segment is close enough to being horizontal/vertical. This can be disabled by holding Ctrl.
  • Reference dimensions and angles can be placed with Shift+D and Shift+N.
  • Copying and pasting entities duplicates any constraints that only involve entities in the clipboard, as well as selected comments.
  • Diameter constraints can be shown as radius.
  • The "pi" identifier can be used in expressions.
  • Constraint labels can be snapped to grid.
  • Integer angles are displayed without trailing zeroes.
  • Angle constraints have proper reference lines and arrowheads.
  • Extension lines are drawn for point-line distance constraints.

New solver features:

  • Sketches with redundant and unsolvable constraints are distinguished.
  • New group setting, "allow redundant constraints". Note that it makes the solver less stable.

New rendering and styling features:

  • New line style parameter: stippling, based on ISO 128.
  • Outlines of solids can be drawn in a particular style (by default, thick lines) controlled by the "Show outline of solid model" button.
  • Occluded edges can be drawn in a particular style (by default, stippled with short dashes) controlled by the "Show hidden lines" button.
  • Solids can be made transparent.

New export/import features:

  • The old "import" command (for .slvs files) is renamed to "link".
  • If a linked .slvs file is not found, first the relative path recorded in the .slvs file is checked and then the absolute path; this is an inversion of the previously used order. If it is still not found, a dialog appears offering to locate it.
  • DXF and DWG files can be imported, with point-coincident, horizontal and vertical constraints automatically inferred from geometry, and distance and angle constraints created when a dimension placed against geometry exists.
  • Triangle mesh can be exported for viewing in the browser through WebGL.
  • Export dialogs remember the last file format used, and preselect it.
  • Exported DXF files have exact circles, arcs and splines instead of a piecewise linear approximation (unless hidden line removal was needed).
  • Exported DXF files preserve color and line thickness.
  • In exported DXF files, constraints are represented as DXF dimensions, instead of piecewise linear geometry.
  • When exporting 2d views, overlapping lines are removed.

Other new features:

  • Native Linux (GTK 2 and GTK 3) and Mac OS X ports.
  • Automatically save and then restore sketches if SolveSpace crashes. (Patch by Marc Britten)
  • Unicode is supported everywhere (filenames, group names, TTF text, comments), although RTL scripts and scripts making heavy use of ligatures are not rendered correctly.
  • The vector font is grid-fitted when rendered on screen to make it easier to read regardless of its size.

2.0

Initial public release.
