It is now possible to create a "New Group | Sketch in New Workplane" from
an existing workplane defined using a point and a nowmal. Before we used to
hit the `ssassert(false, "Unexpected workplane subtype");`.
This makes 4308dc136b more complete and
is related to #1120, #1048 and
https://github.com/solvespace/solvespace/pull/1054
By making IsForcedToMesh() always return true for STL link groups,
rather than trying to set forceToMesh=true during the import phase.
STL link groups are now always shown as "model already forced to
triangle mesh" in the details screen, but also (unlike when the model
is forced to mesh by a parent group) show the '∆' icon in the group
list.
Where each entity in the active workplane sketch is projected a
different amount normal to the workplane, to allow inspection and
easier selection of entities that entirely overlap each other and are
thus otherwise difficult to see or select.
The distance between the exploded "layers" can be controlled in the
configuration page. Negative distances mean the layers are projected in
the opposite direction, relative to the workplane normal.
Create a new copy type for faces that includes the translation aspect of helical extrusions. Also swap the end remappings when the shell is inside out - this was also affecting some Revolve extrusions.
Allows distancing users from the internal "elem" member.
Add Get() and operator[].
Replace direct references to elem.
Make elem and elemsAllocated private in IdList/List.
This commit removes Platform::Window::Redraw function, and rewrites
its uses to run on timer events. Most UI toolkits have obscure issues
with recursive event handling loops, and Emscripten is purely event-
driven and cannot handle imperative redraws at all.
As a part of this change, the Platform::Timer::WindUp function
is split into three to make the interpretation of its argument
less magical. The new functions are RunAfter (a regular timeout,
setTimeout in browser terms), RunAfterNextFrame (an animation
request, requestAnimationFrame in browser terms), and
RunAfterProcessingEvents (a request to run something after all
events for the current frame are processed, used for coalescing
expensive operations in face of input event queues).
This commit changes two uses of Redraw(): the AnimateOnto() and
ScreenStepDimGo() functions. The latter was actually broken in that
on small sketches, it would run very quickly and not animate
the dimension change at all; this has been fixed.
While we're at it, get rid of unused Platform::Window::NativePtr
function as well.
This commit merges all ad-hoc file dialog code, such as the feature
where dialogs remember last location and format, and exposes it
through a common interface.
This commit also significantly improves Gtk dialog handling code.
This commit removes a large amount of redundant code that needed
to be kept in sync between platforms and also makes it much easier
to add new menu-related functionality since little to no platform
code needs to be altered anymore.
This commit also greatly improves code locality in context menu
handling by allowing context menu click handlers to be closures.
This commit temporarily introduces a SetMainMenu API, which is rather
hacky but only necessary until an abstraction for windows is added.
Before this commit, if the source group of a step rotate/translate
group is forced to triangle mesh, the UI would show that the step
rotate/translate group is also forced to triangle mesh, but the group
would in fact contain NURBS surfaces.
This commit updates a *lot* of rather questionable path handling
logic to be robust. Specifically:
* All path operations go through Platform::Path.
* All ad-hoc path handling functions are removed, together with
PATH_SEP. This removes code that was in platform-independent
parts, but had platform-dependent behavior.
* Group::linkFileRel is removed; only an absolute path is stored
in Group::linkFile. However, only Group::linkFileRel is saved,
with the relative path calculated on the fly, from the filename
passed into SaveToFile. This eliminates dependence on global
state, and makes it unnecessary to have separare code paths
for saved and not yet saved files.
* In a departure from previous practice, functions with
platform-independent code but platform-dependent behavior
are all grouped under platform/. This makes it easy to grep
for functions with platform-dependent behavior.
* Similarly, new (GUI-independent) code for all platforms is added
in the same platform.cpp file, guarded with #ifs. It turns out
that implementations for different platforms had a lot of shared
code that tended to go out of sync.
Extrustion top and bottom faces require a normal to be present.
Before this commit, the normal is always taken from the assembled
loop; if the loop could not be assembled (i.e. the loop is broken
or not coplanar) the normal will be (0,0,0), which breaks the sketch.
Also, loops are not generated when generating the sketch
to determine its bounding box.
This may result in spuriously broken sketches when e.g. undoing
a change that has broken a loop.
After this commit, loops are generated when generating for bounding
box, and if the loop could not be assembled, then the workplane
normal is used. This still results in failures when there is
no workplane, but those cases should be quite pathological.
Before this commit, lathe groups had three DOFs, which of course
could not actually move. After this commit, lathe groups have
zero DOFs, as expected.
This bug was introduced in commit 6dced80.
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.
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.
