ConstructCAD v0.5.0

Added

• Arc walls: a selected arc wall shows a round handle at the middle of its arc; drag it to change the curvature (the arc passes through the cursor, its ends stay). While drawing an arc wall, after the start and the end, type a radius and press Enter: the arc takes the cursor's side, the shorter or the longer one, whichever middle is nearer the cursor. wall_create takes radius (signed by the turn) and major_arc.
• Traditional Chinese interface (繁體中文, zh-TW), contributed by @yoyomaimai. It is picked from the system language for zh-TW, zh-HK, zh-MO and zh-Hant.
• Chinese, Japanese and Korean text shows in the interface and in PNG export through the system's CJK fonts (Microsoft JhengHei, PingFang, Noto Sans CJK…). They used to show as boxes. No font is bundled. PDF export still writes such text as ?.
• Doors and windows can be placed in a 3D view: with the Door or Window tool active, click a wall. The opening is centered where you clicked, at the type's sill, facing that side.

Fixed

• Duplicate in the Type Properties dialog kept the default "(copy)" name unless Enter was pressed: clicking OK or another field dropped the typed name. The name is now kept either way.
• Snapping only knew wall axes, so clicks at the corner of a wall, as drawn, missed it (sketching a ceiling inside a room, moving an element). Wall faces and corners, column and stair outlines, sketch edges, railings, and grid lines and their crossings are now snap points in every tool.
• A door or window copied without its wall and pasted on another level stayed on the wall it was copied from. It now goes into the wall where it lands on the target level, and is skipped when there is no wall there.
• Elevations and sections of a project with nothing modelled yet showed no level lines. They now span the grids, or a few meters from the origin.
• The Filters and View Templates dialogs grew a little every frame until their header, list and buttons left the window, leaving a blank panel: the divider between the list and the details took the dialog's whole height. It now ends with the taller column.
• Floors, roofs and ceilings created from walls follow the outer boundary of the level's walls: interior walls meeting the outer corners no longer lead them around an inner loop (an L-shaped house got its old rectangle), and walls hanging off the outline (garden walls) are left out. With separate buildings on a level, the largest is taken.
• Zoom to fit in plans frames the model and its annotation, leaving out the elevation markers around it and the far clip lines of sections, so the building no longer looks small.
• View filters: a rule on a field that none of the filter's categories has (width on walls) matched nothing without a word. filter_create and filter_set now refuse it, naming the categories the field applies to, and the filter editor only offers the fields of the checked categories. Door schedules can show the sill height.
• Download in the update notice and the repository link in About did nothing: the app was built without opening links in the browser.
