Happy New Year everyone! I’ve just put out a minor demo update with a new selection menu, optimised intersection testing when aligning parts together, and several bug fixes.
Selection menu
This is a new menu that provides more ways to add and remove parts to / from the selection. It’s accessible by holding the Right Mouse Button, deletion has now been moved to Left Shift + RMB by default. Of course the key bindings can be changed (in the controls options menu) if you prefer.

With the selection menu you can:-
- Toggle targeted part selected (shortcut key: Left Ctrl + LMB).
- Select all parts in targeted construction, deselecting anything previously selected (shortcut key: Left Ctrl + A).
- Add targeted construction to the selection, without deselecting anything.
- Grow the selection, adds parts neighbouring those already selected (shortcut key: Left Ctrl + Up Arrow).
- Shrink the selection, removes parts with unselected neighbours (shortcut key: Left Ctrl + Down Arrow).
- Invert the selection, selects parts in targeted construction other than those already selected (shortcut key: Left Ctrl + I).
- Deselect all parts (same as left clicking while not targeting anything).
- An option to enable selecting both highlighted parts when targeting an attachment.
- Destroy all selected parts.
I hope to expand this menu eventually to include things like: the ability to hide selected parts, save & recall selections, and filter selection by part type, material, paint colour etc.
