Selecting and editing

Editing levels

Rivet works like ZModeler: pick a part first, then edit its points or faces.

Key	Level	You select
`1`	Object	Whole parts
`2`	Vertex	Points
(tool header)	Edge	Edges
`3`	Polygon	Faces

At Object level, click a part in a view (or Alt+click its box in the tree).
Press 2 or 3 to edit that part's vertices or faces.

Selecting

Click selects. Ctrl adds, Shift removes, Ctrl+Shift toggles.
Drag on empty space draws a box.
Ctrl+A all, Ctrl+D none, Ctrl+I invert. Grow / Expand (tool shelf) widen the selection.
At vertex or polygon level, L adds the connected piece under the cursor; at edge level it picks the edge loop.
Ignore backfaces (on by default) stops clicks grabbing the far side of a part.

Move, rotate, scale

Pick the tool: W move, E rotate, R scale (press it again to switch between World and Local axes).
Drag a handle of the gizmo. Alt while dragging snaps (5 cm, 15°, 0.1x). Right click or Esc cancels.
The X Y Z buttons in the tool header (or the letters on a view's tripod) limit the axes.

Handy extras:

Arrow keys nudge with the Move tool: 1 cm, Shift 10 cm, Ctrl 1 mm.
Shift+D duplicates the selection and picks the copy up: move the mouse, click to put it down.
On surface (Move options): drag a part over the body and it sits on it, turning with the curve. Good for badges.
Custom pivot (each view's Pivot helper menu): rotate, scale and mirror about a point of your own.

Modelling tools

Find them on the Modify tab and the tool shelf. Each is one undo step.

Tool	Level	What it does
Extrude (`T`)	Polygon	Pull the selected faces out; drag up or down
Bevel / Inset	Polygon	Shrink the faces inwards and raise them, with a ring of new faces
Insert	Edge	A new point in the middle of each edge
Bridge	Edge	Join two open edge chains with a strip of faces
Weld	Vertex	Move the selected points to one spot
Break	Vertex / Polygon	Split points or faces loose
Slice / Knife	Any	Cut across an axis / along a line you drag
Mirror	Any	Mirror across the axes that are on
Flip (`F`)	Object / Polygon	Turn faces round
Smooth	Any	Smooth normals by angle; sharper edges stay hard
Calculate normals (`Shift+N`)	Any	Recompute normals
Clone / Duplicate	Object	Copies, with an offset
Rename	Object	Rename many parts at once (find / replace, `{n}` numbers)

Deleting: Del deletes straight away, X asks first. To delete a badge and patch the hole, see Repairing geometry.

The right-click menu

Right-click (without dragging) in a view for: Edit (what fits the level), UV Mapping, Axes (move a part's pivot), Find in views, Linking, Rename and Properties. It never changes the selection.
