Bottom Cap
Closes the bottom opening of the mesh with a solid flat disc and vertical walls. Creates a watertight base for the object — essential for functional prints like containers, cups, and boxes that need to hold contents.
Unlike other effects, Bottom Cap does not displace vertex positions. Instead, the pipeline generates additional cap geometry (disc and walls) that is merged with the main mesh.
Parameters
Thickness (mm)- Height of the solid cap region from the bottom (0.2–20 mm). Controls how many millimeters of the mesh are used for the floor and its vertical walls. Thicker caps provide more structural strength.
Central Hole- 0 = solid closed bottom. 1 = adds a circular hole in the center of the cap. Useful for drainage, cable pass-through, or decorative purposes.
Hole \u00D8 (mm)- Diameter of the central hole in mm (0–100). Only active when Central Hole is enabled. The hole is centered on the cap disc.
How It Works
When Bottom Cap is enabled, the mesh sculptor pipeline generates cap geometry separately from the displacement effects:
- A flat disc is created at the bottom of the mesh, matching the cross-section shape at the base radius.
- Vertical walls connect the disc perimeter to the main mesh wall at the cap thickness height.
- If Central Hole is enabled, the disc is generated as an annular ring with the hole cut out, and an additional inner wall ring connects the hole edge through the cap thickness.
The cap creates hard 90-degree edges where the flat disc meets the vertical walls and where the walls meet the main mesh surface. These hard edges are preserved in the normal computation for correct shading.
