Shaping a surface

Choose an initial surface form, then refine a supported face with Volume Points or Sculpt.

A surface can start flat or use an available shaped preset. Volume Points and Sculpt provide further editing of supported faces. These are surface-shaping controls, not a guarantee that every object or every face has the same editable representation.

Select the object or face

Select a supported shape in 3D. Use Top Surface where the object's Inspector offers surface presets, or open Reshape and select the face to edit.

Choose the starting form

Choose an available preset and edit the fields shown for that preset. Some changes replace existing custom surface data; read Replace Existing Terrain? when it appears and confirm only if you want the replacement. Undo restores the prior surface data.

Use points for controlled heights

Choose Volume Points on an eligible face. Set point Height, Radius and Falloff, and choose the surface Interpolation. Raise by and Set level to distinguish a relative height change from an absolute level.

Use a brush for local shaping

Choose Sculpt where offered. Select Add, Dig, Smooth or Flatten and set the brush radius, strength, shape and edge softness. Apply strokes to the selected surface and inspect their effect.

Finish and set appearance

Finish the point or sculpt edit using its Done action. Assign appearance through the relevant object or face Fill controls. Check other objects placed near the surface; do not assume every placement workflow automatically attaches them to it.
