This week in FreeCAD development:

Draft:

• tetektoza patched the Polygon tool to show a real shape preview rather than a generic circle when adding a polygon to the draft.

• Various fixes from Roy_043, tetektoza, and furgo16.

CAM:

• tarman3 made the new CAM simulator to show the document name in the window title. They also added a button to decrease simulation speed, changed the list of speed values from [1, 10, 40] to [1, 5, 10, 25, 40], and improved camera zoom limits.

• Various fixes from jffmichi, dbtayl, LarryWoestman, tarman3, davidgilkaufman, and otwieracz.

BIM:

• paullee0 continued adding support for the ArchSketch add-on.

• tetektoza added a button for the BIM Views submenu to activate a working plane of the selected item. He also made it possible to change the Sill parameter once a Window object has already been created.

• Various fixes by furgo16, marcuspollio, Roy_043, tetektoza, and paullee0.

FEM:

• marioalexis84 implemented solving electrostatic systems with CalculiX by analogy with the steady-state heat equation.

• NewJoker and ickby fixed several issues.

TechDraw:

• chennes fixed a hatch size constraint introduced by an earlier patch.

• WandererFan made it possible for non-shape views (Symbols, DraftView, BIMView, etc.) to have children.

Materials: triato and chennes fixed a couple of issues.
