Named variables. View → Variables, then type #thickness in any dimension. Change it once and everything that uses it moves.
Section view. View → Section View clips the preview through the origin so a shelled interior is visible.
Weight painting. Rig workspace → Weights → Paint Weights. Pick a bone and drag. Heat map is a texture, not vertex colour.
A first rigging tutorial. Help → Start Rigging Tutorial: post, sign, a bone from each, pose, compile.
Pose the rig in-tool. Press Pose, drag a bone, the mesh bends. Reset Pose puts it back. Nothing is saved.
Make a bone from a part. Right-click a part (or press Bone from Part): it measures the long axis and pins the part to it.
Same from the feature tree — one click for every part that feature made.
The bone takes the part’s name. Select a bone first and new ones hang off it. Cubes and spheres are skipped (no long axis).
Assign a part to a bone from the Parts list. Right-click → Assign to bone. The row shows which bone it is on.
Paint Falloff and an Erase button on the paint bar. Ctrl still inverts for one stroke.
Hold Ctrl to erase paint. The ring turns red. Same size, strength and falloff as the brush.
Drag a box to select in a sketch. Left-to-right is fully inside; right-to-left is anything the box touches.
A sketch Mirror tool. Select geometry, arm Mirror, click the line. The copy stays symmetric.
Revolve can spin about a line you drew in the sketch, including construction lines. Move the line and the axis follows.

Bone from Part is on the Rig bar, not only the right-click menu. In Rig, right-clicking the solid opens the same part menu.
The tool row scrolls left and right when the buttons no longer fit. Wheel pans; Shift jumps further.
Unpainted paint bakes over grey, not white. Preview and compile match, and one dab no longer makes a white brick.
The material brush works on more than one body. It paints whichever is nearest.

Assign Body stayed grey after you picked a part. Select a bone, select a part, press Assign — that pins them. With no part selected it still arms click-to-assign.
Compile no longer binds the paint atlas to slot 0 blindly. It binds the slots the painted faces actually wear.
Paint on two bodies at once is an error with a remedy, not a silent no-op.
The dead Blend combo is off the paint bar. Old files still load; it does not change the fallback any more.

Variables, weight paint, and a first-rig loop
