Wedges and Multi-Shape Building in Scrap Mechanic

The Physics & Wedge Update

Axolot shipped the Physics & Wedge Update in December 2024, months before Scrap Mechanic 1.0 launched on July 24, 2026. That patch introduced wedge blocks for every standard building material — wood, metal, concrete, plastic and the full block palette. Wedges survived the Drilling Thunder overhaul unchanged and remain essential in the current 1.0.4 build.

Before wedges, builders stacked full cubes and accepted boxy silhouettes. Now you can taper noses, round corners, slope roofs and trim aerodynamic shells without modding or glitch-stacking half blocks.

Every material has wedge variants

The wedge system mirrors the cube catalog: if a material exists as a full block, it exists as a wedge in the same tier. Wood wedges craft at the Craftbot from the start. Metal and refined-material wedges unlock with their cube counterparts through quests and Schematics.

Practical implications:

• Wood wedges — cheap prototyping for first vehicle shapes before you commit metal.
• Metal wedges — durable noses for mining rigs and warehouse ram bars.
• Plastic wedges — lightweight fairings on hovercraft and racing builds.

In Creative Mode, every wedge variant spawns instantly. In Survival, check the live Craftbot menu — pre-1.0 wiki lists often miss plastic and concrete wedge entries added in late patches.

Vehicle shaping with wedges

Wedges change how vehicles handle terrain and collisions:

1. Nose taper — a metal wedge nose deflects Haybot hay bales and reduces front-face collision area on high-speed runs.
2. Underbelly slope — wedges under the chassis clear rocks on Mining Island causeways without lifting the whole frame.
3. Wheel arches — quarter wedges around wheels prevent block-snagging on 45-degree slopes.
4. Roof fairings — wedge stacks above the driver seat lower the centre of mass compared to cube towers.

For full chassis philosophy — wheel placement, mass balance and engine tuning — read vehicle design. Wedges are the cosmetic and collision layer on top of those fundamentals.

Base aerodynamics and aesthetics

Bases benefit from wedges as much as vehicles:

• Sloped raid walls — Haybot projectiles glance off angled faces better than flat vertical stacks.
• Roof drainage — wedge roofs shed rain visually in 1.0 weather and reduce flat surfaces where Tapebots line up shots.
• Interior trim — wedge corners in watchtowers widen sightlines without sacrificing wall thickness.
• Garage ramps — combine wedges with Sticky wheels for smooth Scrap City blueprint imports.

None of this replaces proper defensive base geometry, but wedges make the same defence layout look intentional instead of Early Access boxy.

Multi-shape parts in 1.0

Drilling Thunder extended the wedge concept into multi-shape part families. Several 1.0 blocks ship in corner, slope and half-length variants alongside wedges — ladders, pipe covers, decorative panels and refined-metal trim from the new 1.0 parts roster.

When planning a build:

• Open the Craftbot category filter and scroll the Shapes sub-tab.
• Match wedge material to adjacent cube material — mixed wood/metal wedge transitions stress joints in physics-heavy vehicles.
• Use the Lift tool rotate mode to flip wedges into inverted slopes for ceiling trim.

Multi-shape parts connect with the same F attach rules as cubes. Bearing mounts on wedge faces work normally; just confirm the bearing arrow points along your intended rotation axis.

Connect Tool tips with wedges

Wedges do not change Connect Tool wiring, but they change where you can hide logic:

• Concealed sensor lines — run Connect Tool links through wedge tunnels built into chassis rails instead of exposed overhead beams.
• Compact engine bays — wedge side panels leave room for a Battery and Controller beside the Driver Seat on small tractors.
• Turret cowlings — wedge shells around Turret Seat mounts protect bearings from Tapebot tape without blocking arc fire.

When linking bearings on wedge-heavy builds, test rotation in an empty flat world first. Long wedge noses shift the centre of mass forward — compensate with a counterweight block or rear engine placement before you wire throttle logic.

Recommended learning path

1. Build a wood wedge nose on your first vehicle and drive the Mechanic Station loop.
2. Rebuild the nose in metal before your first warehouse trip.
3. Experiment with wedge roof lines on a raid wall using the protect farm choke layout.
4. Import a wedge-heavy blueprint through the Scrap City Garage once you reach mid-campaign.

Common wedge mistakes

• Mixing materials on load-bearing wedge seams — wood wedges bolted to metal cubes fail first in collisions.
• Over-wedging the nose — extreme taper reduces attach points for headlights and Spud Gun mounts.
• Ignoring mass — wedge stacks add the same mass as cubes; aerodynamic looks do not reduce weight.
• Forgetting inverted wedges — many builders only place default-orientation slopes and miss ceiling and undercarriage options.
