This week in FreeCAD development:

Sketcher:

• PaddleStroke created a ConstraintLineByAngle helper.
• FlachyJoe cleaned up planegcs/Geo code.
• theo-vt patched the workbench to update multiple geometry IDs at a time rather than just one when scaling is applied.

PartDesign: theo-vt patched the code to allow open wires for profile normal detection. This fixes a bug where holes from arcs would have the wrong orientation.

TechDraw:

• WandererFan fixed a regression that caused v1.1 files to become unreadable in v1.0.
• Syres916 fixed the automatic sizing of the TaskFillTemplate’s dialog and a regression where equal tolerances would display an additional incorrect symbol.

**FEM: **NewJoker added two new properties to FEM Constraint contact: one to enable thermal contact and one to define its properties-a list of gap conductance values optionally paired with contact pressure and temperature. He also added a unitless Offset property to shell sections.

GUI:

• Rexbas increased the focal distance in the orthographic view as a workaround for the missing clipping offset in the Coin library (he also contributed the real fix to Coin, review is pending).
• kadet1090 and MisterMakerNL contributed numerous fixes to the default stylesheet.

I/O:

• baidakovil contributed a patch that allows users to customize WebGL exports with their own templates.
• furgo16 updated the DXF C++ importer to support nested block definitions and allow users to choose parametric or flattened importing of blocks and assemblies.

Among other changes:

• Roy-043 and paullee0 contributed several fixes to BIM and Draft.
• theo-vt fixed a regression in Part code that affected Assembly and TechDraw.
• captain0xff refactored SoRotationDragger as part of his GSoC work on implementing interactive controls in the 3D View.
• z0r0 fixed the Fanuc post-processor (in CAM), which will now search for tool attributes that actually exist.

Additional improvements and fixes were contributed by chennes, oursland, mosfet80, Syres916, hyarion, and theo-vt.

PR stats: since the previous report, 31 pull requests have been merged, and 39 new pull requests have been opened.

Issue stats: overall, there are 2906 open issues in the tracker, down by 2 from last week.

Elsewhere in the community, Federico Rosa began working on a new workbench called Solar, which uses LadyBug tools for solar positioning and animating it over a specified period.

Alex Sadowski will be representing FreeCAD at FrOSCon in Sankt Augustin (Germany) this August, with a talk and a stand.
