This week in FreeCAD development, the most actively worked-on parts of FreeCAD have been the toponaming project, Sketcher, FEM, and UI/UX.

Toponaming:

• CalligaroV imported and improved the WireJoiner class.

• bgbsww fixed a few issues, made minor improvements, and added Python implementations for CompSolid, Face, Shell, Solid, as well as missing entries in TopoShape.

Sketcher:

• Roy-043 renamed “Map sketch to face…” in the main menu to “Attach sketch…” for clarity.

• PaddleStroke implemented a midpoint autoconstraint, fixed a bug in Chamfer tool code, as well as a bug with a B-Spline icon in construction line mode.

• FlachyJoe added an arc length constraint.

FEM:

• marioalexis84 improved post-processing object style.

• NewJoker changed 2D element thickness from 20 to 1 by default.

• lyphrowny fixed and typo in FEM code and removed calculix from solvers tab in examples.

• davesrocketshop added the property ‘Thermal Expansion Reference Temperature’ to the Thermal properties in the new materials editor.

UI/UX:

• Roy-043 made “View Left” the last option in the “Individual views” toolbar.

• maxwxyz updated FEM and Part Design icons for better consistency and added a missing “View Top” option. He also added missing commands to the tree context menu.

• PaddleStroke added an opt-in Tab-Bar workbench selector (enabled in Preferences). He also fixed the toggling of objects’ transparency in some scenarios and improved the double-click behavior for spreadsheet objects to switch to the Spreadsheet WB.

• NomAnor made it possible to allow adding transformations to MultiTransform if there is no active Body.

Among other changes:

• wwmayer fixed a lot of bugs and developed a new function to approximate B-Spline from points.

• Roy-043 added a new Fuse property to patharray and pathtwistedarray in Draft. This fixes a problem when applying union/intersect to a point array and other objects.

• tomate44 enabled multi-threading to distToShape following a change in OCCT (starting with v7.6.0). This brings an ×3 to ×6 performance boost on a rather complex 20MB STEP file.

• adrianinsaval fixed building new material code on Windows with debugging enabled.

• NomAnor patched FreeCAD to ignore suppressed features in patterns (Part Design).

• furgo16 fixed WebGL exporting

• paullee0 made a few fixes and improvements in Arch.

• jamwaffles added feed retract option to drilling op settings for reaming/boring heads in CAM.

• yorikvanhavre made it possible to unset modified state with Python code.

• chennes fixed some minor bugs.

• WandererFan fixed a failure on corrupt dimension reference in TechDraw.
