ShapeCraft 0.5.3-alpha

Fixed:

• A sketch drawn on the ground over a part's top face, then pulled into the part, made a separate body. A shape
  that lies wholly on a face now cuts when pushed in and joins when pulled out, just like one sketched on that
  face. Only partly on the face still makes a new body. The Result badge and the step's card show the same choice.
• Escape inside a sketch now steps back one layer at a time: it puts down the tool, then clears the selection,
  then leaves the sketch. With nothing drawn yet, Escape leaves right away.
• New projects opened a bit too close and slightly turned, so the same clicks made smaller parts than people
  expect. The starting view now looks straight down the diagonal from a little farther back.
• Clicking the middle of a cylinder's wall could select the far side of its bottom edge, hidden behind the wall.
• Selecting a round face (a cylinder's wall, a hole) shows its radius at the bottom, next to "1 face".

Also in 0.5.2-alpha

Fixed:

• While the first-run questions (device, navigation style) were open, keyboard shortcuts still reached the model
  behind them, so ⌘V or a tool key changed a project you couldn't see. They now wait until you answer or skip.
• The Help menu follows the familiar order: Help, then shortcuts and search, then Get Started and Tutorials (which
  now open those pages of the home screen), then reporting a problem, release notes and updates.

Also in 0.5.1-alpha

New:

• Edit ▸ Copy and Paste (⌘C / ⌘V): copy bodies or construction planes and paste them in place as separate,
  selected copies, ready to move. Text fields still copy and paste text as before.
• Export ▸ Slicer lists the slicers you actually have installed (Bambu Studio, OrcaSlicer, PrusaSlicer, Snapmaker
  Orca, UltiMaker Cura, Creality Print, ElegooSlicer), plus your default app for 3MF files, and remembers your pick.
• The Help menu has the three tutorials, the website, release notes and a link for reporting a problem or idea.
• Tool types you pick (Rectangle ▸ 3 Points, Fillet ▸ G2 and the rest) stay picked in your next project and after
  a restart.

Fixed:

• Pulling a round profile showed a fence of thin lines up its side while the preview caught up; it now shows a
  smooth tinted wall, with lines only up real corners.

For scripts and agents:

• ui.edit {action: copy|paste} runs Edit ▸ Copy / Paste.

Alpha: keep copies of anything important. ShapeCraft updates itself from here on: it downloads new
versions in the background and installs them when you close it.

First launch: macOS asks once: System Settings ▸ Privacy & Security ▸ Open Anyway.
Windows SmartScreen: More info ▸ Run anyway. Linux: make the AppImage executable, then double-click it.

Check a download against SHA256SUMS.txt: shasum -a 256 FILE (macOS, Linux) or Get-FileHash FILE (Windows).
