|
3.0
|
|
---
|
|
|
|
New sketch features:
|
|
* Extrude, lathe, translate and rotate groups can use the "assembly"
|
|
boolean operation, to increase performance.
|
|
* The solid model of extrude and lathe groups can be suppressed,
|
|
for splitting a single model in multiple parts to export,
|
|
or if only the generated entities are desired, without the mesh.
|
|
* Translate and rotate groups can create n-dimensional arrays using
|
|
the "difference" and "assembly" boolean operations.
|
|
* A new sketch in workplane group can be created based on existing workplane.
|
|
* TTF text request has two additional points on the right side, which allow
|
|
constraining the width of text.
|
|
* Image requests can now be created, similar to TTF text requests.
|
|
This replaces the "style → background image" feature.
|
|
* Irrelevant points (e.g. arc center point) are not counted when estimating
|
|
the bounding box used to compute chord tolerance.
|
|
* When adding a constraint which has a label and is redundant with another
|
|
constraint, the constraint is added as a reference, avoiding an error.
|
|
* Datum points can be copied and pasted.
|
|
* "Split Curves at Intersection" can now split curves at point lying on curve,
|
|
not just at intersection of two curves.
|
|
* Property browser now shows amount of degrees of freedom in group list.
|
|
|
|
New constraint features:
|
|
* When dragging an arc or rectangle point, it will be automatically
|
|
constrained to other points with a click.
|
|
* When selecting a constraint, the requests it constraints can be selected
|
|
in the text window.
|
|
* When selecting an entity, the constraints applied to it can be selected
|
|
in the text window.
|
|
* It is now possible to turn off automatic creation of horizontal/vertical
|
|
constraints on line segments.
|
|
|
|
New export/import features:
|
|
* Three.js: allow configuring projection for exported model, and initially
|
|
use the current viewport projection.
|
|
* Wavefront OBJ: a material file is exported alongside the model, containing
|
|
mesh color information.
|
|
* DXF/DWG: 3D DXF files are imported as construction entities, in 3d.
|
|
* Q3D: [Q3D](https://github.com/q3k/q3d/) triangle meshes can now be
|
|
exported. This format allows to easily hack on triangle mesh data created
|
|
in SolveSpace, supports colour information and is more space efficient than
|
|
most other formats.
|
|
|
|
New rendering features:
|
|
* The "Show/hide hidden lines" button is now a tri-state button that allows
|
|
showing all lines (on top of shaded mesh), stippling occluded lines
|
|
or not drawing them at all.
|
|
* The "Show/hide outlines" button is now independent from "Show/hide edges".
|
|
|
|
New measurement/analysis features:
|
|
* New choice for base unit, meters.
|
|
* New command for measuring total length of selected entities,
|
|
"Analyze → Measure Perimeter".
|
|
* New command for measuring center of mass, with live updates as the sketch
|
|
changes, "Analyze → Center of Mass".
|
|
* New option for displaying areas of closed contours.
|
|
* When selecting a point and a line, projected distance to current
|
|
workplane is displayed.
|
|
|
|
Other new features:
|
|
* New command-line interface, for batch exporting and more.
|
|
* The graphical interface now supports HiDPI screens on every OS.
|
|
* New link to match the on-screen size of the sketch with its actual size,
|
|
"view → set to full scale".
|
|
* When zooming to fit, constraints are also considered.
|
|
* When clicking on an entity that shares a place with other entities,
|
|
the entity from the current group is selected.
|
|
* When dragging an entity that shares a place with other entities,
|
|
the entity from a request is selected. For example, dragging a point on
|
|
a face of an extrusion coincident with the source sketch plane will
|
|
drag the point from the source sketch.
|
|
* The default font for TTF text is now Bitstream Vera Sans, which is
|
|
included in the resources such that it is available on any OS.
|
|
* In expressions, numbers can contain the digit group separator, "_".
|
|
* The "=" key is bound to "Zoom In", like "+" key.
|
|
* The numpad decimal separator key is bound to "." regardless of locale.
|
|
* On Windows, full-screen mode is implemented.
|
|
* On Linux, native file chooser dialog can be used.
|
|
|
|
Bugs fixed:
|
|
* A point in 3d constrained to any line whose length is free no longer
|
|
causes the line length to collapse.
|
|
* Curve-line constraints (in 3d), parallel constraints (in 3d), and
|
|
same orientation constraints are more robust.
|
|
* Adding some constraints (vertical, midpoint, etc) twice errors out
|
|
immediately, instead of later and in a confusing way.
|
|
* Constraining a newly placed point to a hovered entity does not cause
|
|
spurious changes in the sketch.
|
|
* Points highlighted with "Analyze → Show Degrees of Freedom" are drawn
|
|
on top of all other geometry.
|
|
* A step rotate/translate group using a group forced to triangle mesh
|
|
as a source group also gets forced to triangle mesh.
|
|
* Paste Transformed with a negative scale does not invert arcs.
|
|
* The tangent arc now modifies the original entities instead of deleting
|
|
them, such that their constraints are retained.
|
|
* When linking a sketch file, missing custom styles are now imported from
|
|
the linked file.

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

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.
|
|

|
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.
