Improvements now identify cases where selected faces create a closed loop that creates an internal closed wire to not be processed.
Remove unnecessary comments.
Add debug statements.
The 0.25 constant used might need to be modified later. Or, the entire `_makeIntersectionTags()` method might need to be improved if other micro-edge use cases cause failure.
Meshing tolerance settings for 3d surface operations were ignored since
switching to directly using facets from the view tesselation. On complex
3d shapes, this could cause serious meshing artifacts in the generated
paths, serious enough to show up even in path previews.
Additionally, there were occasionally segfaults when a model was not
viewed and thus implicitly tessellated before starting an OCL operation.
This patch switches from using view tessellations to explicitly calling
`tessellate()`. While this is usually more expensive than using the
existing view tessellation, recent changes to parallelize tessellation
have reduced this additional cost significantly.
Note that this diff only restores the use of LinearDeflection, since
that is the main thing we care about in OCL use cases. Angular
deflection is still ignored, but I think this is a good thing for this
case since a highly refined mesh in tiny but heavily curved areas below
the linear deflection threshold just adds unnecessary cost. If there is
agreement on this point, then we can remove the preference for
AngularDeflection from the UI in a follow-up.
This feature allows the user to import base geometry from an existing operation in the same Job. The imported geometry is still passed through the shape type filter as if it were manually selected in the viewport.
Path: Post-test updates
Avoid spurious diffs from inadvertent newline changes by letting git
normalize newlines in the path module as well, just as a list of other
modules including Draft already do.
This effectively standardizes all checked-in code to Unix newlines, but
checkouts might use CRLF if that is the user preference.
New option allows access to previously inaccessible faces.
Corrected property label names in UI panel, and added `Face Region` option to boundary shape list.
- Only apply aggressive optimizations to short horizontal moves within
cutter diameter. The safe model STL does not accurately reflect stock
state, so using it for determining long distance move safe heights is
not safe. There would be a high chance of hitting the stock at rapid
speeds.
Thankfully, the vast majority of step-overs tend to be short, so are
still optimized.
- For short moves, only allow completely lift-free transitions when
there is (almost) no Z change, and the min safe travel height does not
rise above the same level.
Otherwise, lift to the max of end points and min safe travel height
first, then move horizontally. A future optimization would be to
directly use the drop scan for transition path generation.
Improve `HandleMultipleFeatures` processing when set to `Collectively` by implementing new class to refine the processing area, attempting to remove common edges between connected face regions.
Open-edges will now work in simple cases where user selects bottom edge, without requiring adjustment to Final Depth. This will speed up procedural usage of the operation for open edges by re-enabling the `select-edge_create_OK` work flow.
The guessing procedure for Final Depth based on Base Geometry selected is fixed in `UpdateDepths()` method.
Improvements to user messages.
Remove unnecessary code and comments.
Improve debugging feedback.
- Do not show editor when gcode size exceeds 100kb. The poor editor
widget cannot handle that much output, and will hang FreeCAD.
- Avoid quadratic behavior in output accumulator. While Python greater
than 2.7 avoids quadratic behavior in string accumulators, this optimization
is defeated when the string is forced to be materialized to contiguous
memory, as was done by the `.trim()`. As a result, we got quadratic complexity,
ensuring that large jobs would never successfully be post-processed.
