Screen Curving

LED.FYI supports curved screen configurations, allowing you to model concave and convex LED walls. Curving is configured per screen and affects the 3D preview, BOM calculations, and PDF export.

Enabling Curving

In the Screens sidebar panel, expand a screen and find the Curving section. Check Enable to activate curving for that screen.

When enabled, the screen defaults to Simple mode with a 5-degree angle per junction.

Curving Modes

Simple Mode

Applies a uniform angle at every vertical junction across the screen width. Controls:

• Angle per junction — The bend angle in degrees at each junction between adjacent panel columns. Accepts values from -45 to +45 in 0.5-degree increments.
  • Positive values = concave (curving toward the viewer)
  • Negative values = convex (curving away from the viewer)

The panel displays calculated values based on your angle and panel width:

• Radius — The curve radius in millimeters and meters
• Diameter — The full diameter of the implied circle
• Total curve — The cumulative angle across all junctions

Compound Mode

Allows different bend angles for different column ranges within the same screen. This is useful for screens that aren't uniformly curved — for example, a screen that's flat in the center with curved wings.

Each range definition specifies:

• Start column and end column (1-indexed, inclusive)
• Angle per junction within that range

Click + Add range to define additional curve segments. Ranges can overlap or leave gaps (gaps default to 0-degree / flat junctions).

Pivot Location

The Pivot on outside edge checkbox controls where panels rotate from:

• Unchecked (default) — Panels pivot on their inner (front-facing) edge
• Checked — Panels pivot on their outer (back-facing) edge

This affects the overall radius and how the physical panel depth impacts the curve geometry.

Panel Type Constraints

Some panel types in the equipment library have curving constraints:

• Max concave angle — The maximum positive angle the panel supports
• Max convex angle — The maximum negative angle the panel supports
• Curve increments — Specific allowed angles (e.g., 0, 2.5, 5, 7.5 degrees). When set, angles snap to the nearest allowed value.
• Built-in curving — Panels with built-in curving mechanisms don't require external curving blocks

Angles are automatically clamped to the panel's constraints when you adjust them.

BOM Impact

For panels without built-in curving mechanisms, the BOM calculates the curving hardware needed:

• 4-way blocks — Used at interior row boundaries between curved panels. Count: (rows - 1) per junction with a non-zero angle.
• 2-way blocks — Used at the top and bottom edges of curved junctions. Count: 2 per junction with a non-zero angle.

Block counts are broken down by angle value, since different angles may require different block sizes. The BOM and PDF export include a curving blocks summary table.

3D Preview

Curved screens render as true curved surfaces in the 3D View. The panels bend according to the configured junction angles, giving an accurate spatial preview of the installation. Content from linked surfaces renders correctly on the curved geometry.

PDF Export

The Paperwork Export includes a Curving Diagram section (toggleable) for each curved screen, showing:

• A top-down view of the panel layout with junction angles
• Curving block counts (4-way and 2-way) grouped by angle
• Radius and diameter measurements for simple mode curves

Curving Calculator

A standalone Curving Calculator tool is available from the Calculators page. It lets you experiment with curving parameters without creating a full project:

• Simple mode — Input panel width, count, angle, and depth to see radius/diameter/circumference
• Compound mode — Define a screen width with multiple curve ranges and visualize the resulting layout

This is useful for pre-planning curve geometry before committing to a project configuration.
