Update changelog for 2.2.
2016-06-23 02:52:47 +00:00
3.0
---
Allow combining extrude, lathe, translate and rotate group as assemblies. This significantly improves performance e.g. in case of a sketch containing a multitude of wooden panels, as the meshes can be merely transformed instead of being joined.
2016-05-03 07:44:10 +00:00
New sketch features:
* Extrude, lathe, translate and rotate groups can now use the "assembly"
boolean operation, to increase performance.
Allow creating n-dimensional arrays with translate and rotate groups. Before this commit, a translate group based on another translate group would always use the "union" boolean operation, which does not work at all if one wants an array with a difference operation, and results in degraded performance if one wants an array with an assemble operation.
2016-10-11 16:46:42 +00:00
* Translate and rotate groups can create n-dimensional arrays using
the "difference" and "assembly" boolean operations.
Add an ability to create a workplane with another workplane. This is useful in case one wants to create a workplane based on one of the reference ones, to be explicit, or to avoid fishing out again the line segments used to create a workplane at an angle.
2016-11-17 04:30:54 +00:00
* A new sketch in workplane group can be created based on existing workplane.
Add two more points to the TTF text request. These points can be used for constraining the width of the text (or to the width of the text). The main parts of the commit are: * TtfFont is restructured to be able to return the aspect ratio for a given string. * This aspect ratio is written to the savefile, such that even if the font is missing, the sketch would still be solved correctly. * The two additional points are constrained via perpendicularly to the two main points (which form a v vector). The compatibility features are as follows: * When the font is missing in old files, 1:1 aspect ratio is used, which works for the replacement symbol anyhow. * When the two additional points are missing in old files, their would-be positions are calculated and they are moved there, avoiding 'jumping' of underconstrained sketches.
2016-10-11 01:58:04 +00:00
* TTF text request has two additional points on the right side, which allow
constraining the width of text.
Don't consider arc center point for bounding box calculation.
2016-10-30 10:26:31 +00:00
* Irrelevant points (e.g. arc center point) are not counted when estimating
the bounding box used to compute chord tolerance.
Choose entities to select in a way appropriate for the operation. Before this commit, when an entity is clicked at or dragged, and it shares a place with other entities, which of them is selected is decided more or less at random. This is particularly annoying when dragging. After this commit, when clicking, an entity from the current group is given preference, and when dragging, an entity from a request is given preference. This allows e.g. dragging points of a sketch even when an extrusion of that sketch is active.
2016-07-21 17:58:18 +00:00
* 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.
Allow combining extrude, lathe, translate and rotate group as assemblies. This significantly improves performance e.g. in case of a sketch containing a multitude of wooden panels, as the meshes can be merely transformed instead of being joined.

Update changelog for 2.2.
2016-06-23 02:52:47 +00:00
New export/import features:
* Three.js: allow configuring projection for exported model, and initially
use the current viewport projection.
Wavefront OBJ: export mesh color as well.
2016-07-04 06:02:30 +00:00
* Wavefront OBJ: a material file is exported alongside the model, containing
mesh color information.
DXF: Import Z coordinate from DXF/DWG files.
2016-11-19 10:19:08 +00:00
* DXF/DWG: 3D DXF files are imported as construction entities, in 3d.
Update changelog for 2.2.
2016-06-23 02:52:47 +00:00
Allow displaying outlines without any other edges. As usual, what's displayed is what's exported.
2016-08-14 00:55:27 +00:00
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".
Implement Analyze → Measure Perimeter.
2016-08-01 13:18:58 +00:00
Other new features:
Implement a command-line interface. This commit adds a basic command-line interface. This interface allows rendering thumbnails and exporting data in batch mode.
2016-11-29 02:57:41 +00:00
* New command-line interface, for batch exporting and more.
Implement Analyze → Measure Perimeter.
2016-08-01 13:18:58 +00:00
* New command for measuring total length of selected entities,
"Analyze → Measure Perimeter".
Implement "view → set to full scale" text window command.
2016-08-01 13:44:38 +00:00
* New link to match the on-screen size of the sketch with its actual size,
"view → set to full scale".
Also consider constraints when zooming to fit. Before this commit, when working on convex sketches, zooming to fit was guaranteed to clip most or even all constraints, making it quite useless.
2016-08-01 14:00:00 +00:00
* When zooming to fit, constraints are also considered.
Update CHANGELOG.
2016-10-10 23:43:09 +00:00
* When selecting a point and a line, projected distance to to current
workplane is displayed.
Allow the digit group separator, "_", in expressions.
2017-01-02 23:34:36 +00:00
* In expressions, numbers can contain the digit group separator, "_".
Update CHANGELOG.
2016-10-10 23:43:09 +00:00
* The "=" key is bound to "Zoom In", like "+" key.
GTK, Win32: always map keypad decimal separator to dot. We only accept dot as a decimal separator, but the OS locale may use a comma there.
2017-01-02 23:16:09 +00:00
* The numpad decimal separator key is bound to "." regardless of locale.
Implement Analyze → Measure Perimeter.
2016-08-01 13:18:58 +00:00
Rewrite equations generated for pt-on-line constraints. Before this commit, pt-on-line constraints are buggy. To reproduce, extrude a circle, then add a datum point and constrain it to the axis of the circle, then move it. The cylinder will collapse. To quote Jonathan: > On investigation, I (a) confirm that the problem is > the unconstrained extrusion depth going to zero, and (b) retract > my earlier statement blaming extrude and other similar non-entity > parameter treatment for this problem; you can easily reproduce it > with a point in 3d constrained to lie on any line whose length > is free. > > PT_ON_LINE is written using VectorsParallel, for no obvious reason. > Rewriting that constraint to work on two projected distances (using > any two basis vectors perpendicular to the line) should fix that > problem, since replacing the "point on line in 3d" constraint with > two "point on line in 2d" constraints works. That still has > the hairy ball problem of choosing the basis vectors, which you > can't do with a continuous function; you'd need Vector::Normal() > or equivalent. > > You could write three equations and make the constraint itself > introduce one new parameter for t. I don't know how well that > would work numerically, but it would avoid the hairy ball problem, > perhaps elegant at the cost of speed. Indeed, this commit implements the latter solution: it introduces an additional free parameter. The point being coincident with the start of the line corresponds to the parameter being zero, and point being coincident with the end corresponds to one). In effect, instead of constraining two of three degrees of freedom (for which the equations do not exist because of the hairy ball theorem), it constrains three and adds one more.
2016-11-01 16:06:57 +00:00
Bugs fixed:
* A point in 3d constrained to any line whose length is free no longer
causes the line length to collapse.
Rewrite equations generated for same-orientation constraints. This has the same motivations and implementation as in 3d6d873.
2016-11-27 08:43:21 +00:00
* Curve-line constraints (in 3d), parallel constraints (in 3d), and
same orientation constraints are more robust.
Force DOF check every time a constraint is added. Before this commit, it was possible to add some redundant constraints (e.g. vertical, horizontal or midpoint) without failing the sketch, because SolveBySubstitution() removed the redundant equations. However, this could result in the solve failing later because the system didn't converge, without any pointers as to the true cause of the failure.
2016-10-22 15:08:41 +00:00
* Adding some constraints (vertical, midpoint, etc) twice will now error out
immediately, instead of later and in a confusing way.

2.3
---
Bug fixes:
* Do not crash when applying a symmetry constraint to two points.
* Fix TTF font metrics again (properly this time).
Fix detection of transparent meshes. SSurface::TriangulateInto first populates the mesh with triangles that have no color, and then paints them, which confused the code that detects if a mesh is transparent into thinking that all of them are; and that broke the "draw back faces in red" feature, since it is disabled for transparent meshes.
2016-11-18 11:00:55 +00:00
* Fix the "draw back faces in red" option.
DXF: Fix export of wireframe as 3D DXF. Before this commit, polylines got flattened but all other entities got exported with the proper Z coordinate. After this commit, all entities are exported with proper Z coordinate. Also, instead of exporting LWPOLYLINE (2d only), POLYLINE (2d/3d) is exported; as a bonus it is more compatible with 3rd party software, since it is older.
2016-11-26 08:17:20 +00:00
* Fix export of wireframe as 3D DXF.
OS X: fix another out-of-bounds TW.META access. See also f5a37ae.
2016-11-05 17:04:34 +00:00
* Various minor crashes.
Update CHANGELOG.

Update changelog for 2.2.
2016-06-23 02:52:47 +00:00
2.2
---
Other new features:
* OS X: support 3Dconnexion devices (SpaceMouse, SpaceNavigator, etc).
Update CHANGELOG.
2016-10-10 23:43:09 +00:00
* GTK: files with uppercase extensions can be opened.
Update changelog for 2.2.
2016-06-23 02:52:47 +00:00
Bug fixes:
Do not remove autosave after successfully opening file. If SolveSpace crashes after the open, or hangs and is forcibly killed, data would be lost. (I lost my data.) Instead, remove autosave only in two cases: right after a successful save, or right after a save is declined. This should be completely safe.
2016-06-23 02:50:25 +00:00
* Do not remove autosaves after successfully opening a file, preventing
data loss in case of two abnormal terminations in a row.
Don't crash when changing the autosave interval.
2016-06-23 11:55:15 +00:00
* Do not crash when changing autosave interval.
Fix the "Show degrees of freedom" command. Before this commit, it never highlighted anything at all. It was broken when chord tolerance calculation was overhauled.
2016-06-27 15:25:41 +00:00
* Unbreak the "Show degrees of freedom" command.
Update changelog for 2.2.
2016-06-23 02:52:47 +00:00
* Three.js: correctly respond to controls when browser zoom is used.
* OS X: do not completely hide main window when defocused.
GTK: make Space Navigator actually work. Before this commit, no events would actually be received.
2016-06-27 10:35:17 +00:00
* GTK: unbreak 3Dconnexion support.
Multiply constraint values by scale when pasting with transformation.
2016-07-19 12:12:01 +00:00
* When pasting transformed entities, multiply constraint values by scale.
Unbreak TTF metrics. In 2.0, the distance between the points in the TTF request specified cap height. In 2.1, that was accidentally changed to some arbitrary value near cap height instead, due to a 72pt factor mess-up. This commit restores the old behavior.
2016-08-01 12:27:29 +00:00
* Fix TTF font metrics (restore the behavior from version 2.0).
Update CHANGELOG.
2016-08-13 05:08:34 +00:00
* Forcibly show the current group once we start a drawing operation.
* DXF export: always declare layers before using them.
Get rid of the MAX_SELECTED restriction in GroupSelection().
2016-08-13 05:20:43 +00:00
* Do not truncate operations on selections to first 32 selected entities.
Make translate/rotate groups inherit the "suppress solid model" option.
2016-10-09 13:26:58 +00:00
* Translate and rotate groups inherit the "suppress solid model" setting.
Update CHANGELOG.
2016-10-10 23:43:09 +00:00
* 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.
Update changelog for 2.2.
2016-06-23 02:52:47 +00:00
Add CHANGELOG.md.
2016-06-11 22:30:26 +00:00
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.
