🧰 Kayser's Blueprint Designer's Toolkit

Formerly known as Kayser's Designer's Toolkit.

Kayser's Blueprint Designer's Toolkit (BDT) is a quality-of-life mod for Captain of Industry blueprint creators.

It is built around one rule: designer-only, consumer-free. Players who download and use your blueprints do not need this mod installed. BDT helps with creating, documenting, updating, inspecting, and cleaning up blueprints, but the output remains normal vanilla-compatible blueprint data.

🆕 New in 0.6.0: Throughput monitoring

BDT 0.6.0 turns throughput from a single limiter control into a full inspection workflow for blueprint testing.

You can now display live items/min flow rates directly over transports, sources, sinks, and ports; make entities glow as a throughput heat map; switch values to percent of maximum capacity; and configure whole selected areas at once with the new Throughput Area Tool.

🔁 Update blueprint

Select a blueprint in your blueprint book and click Update to replace its contents with a fresh area selection.

BDT keeps the blueprint's existing:

• name
• description
• overlap settings
• position in the current folder

This is meant for the usual blueprint-authoring loop: find a small mistake, fix it in-world, update the existing blueprint, and keep the book organized.

📂 Remembered blueprint folder

BDT remembers the last blueprint book folder you opened and restores it the next time the blueprint window is created. The folder path is stored in the vanilla save file. This allows you to store different currently open blueprint book page in different save games.

📊 Blueprint operational stats

The blueprint detail panel now also shows Operational cost.

When a selected blueprint contains relevant entities, BDT adds a compact operational summary row showing:

• workers
• electricity
• computing
• maintenance by tier

Only non-zero stats are shown, so small blueprints stay clean and large builds get the extra planning information where it belongs. Operational costs assume 100% utilization on all entities.

📝 Copy as Markdown

BDT adds a Copy as Markdown button to both the blueprint detail panel and the blueprint folder detail panel.

The language used for table headers and product/entity names is controlled by the Markdown table language setting in Mod Settings (see below). The default is English.

Single blueprint - clicking the button copies a Markdown-formatted summary to the clipboard:

• Blueprint heading and description
• Components table - all major entity types and their counts, sorted A-Z
• Construction table - all required products and quantities, sorted A-Z
• Operational table - entities, workers, electricity, computing, and maintenance products per month

Blueprint folder - clicking the button copies a wide Markdown table listing every blueprint in the folder, including blueprints in sub-folders. Each blueprint is a row. Columns include Blueprint name, Folder (relative path within the exported root), Entities, and any workers / electricity / computing / maintenance / construction product columns present across the folder, sorted A-Z. Rows are sorted by folder path, then by blueprint name within each folder.

🧩 Symmetric entity normalization

Mitigation/Fix for: https://discord.com/channels/803508556325584926/1405800905646805093/1405800905646805093

BDT normalizes rotationally-symmetric entities in captured blueprints, such as balancers/zippers and mini-zippers/connectors.

Captain of Industry can treat a functionally identical connector at e.g. rotation 0° and rotation 90° as different, which can block paste-over updates. BDT fixes that at blueprint capture time by resetting symmetric entities' rotation and flip-state to a canonical orientation.

The normalization pass focuses on the known paste-over problem cases:

• resets supported symmetric entities to a consistent stored orientation
• keeps their blueprint position unchanged
• preserves balancer priority settings
• skips entities that do not match the supported symmetric layouts

The result is still normal blueprint data with all (normalized) entities at rotation 0° and non-flipped. This does not patch blueprint placement and does not require blueprint users to install BDT.

This is a passive feature that allows you to freely place connectors, balancers, and lifts in multi-tier blueprints without worrying about their orientation.

⚡ Instant build mode

BDT includes an Instant Build mode (configurable in Mod Settings) that automatically and instantly completes construction, deconstruction, upgrades, and downgrades without consuming materials, workers, or unity. The benefit over the vanilla insta-build toggle is that you don't need to unpause the game and risk having products end up in the wrong places when your build is being modified.

Enabling this feature turns off the game's built-in insta-build toggle.

🧹 Transport cleanup tool

BDT adds a transport cleanup tool with a default hotkey of Alt+Del. This tool allows you to detect and demolish useless belts and pipes via an area selection drag, before capturing your blueprint. To avoid capturing input and output transports, terminate them properly with a source or sink.

The hotkey can be changed in BDT's mod settings under TRANSPORT CLEANUP.

👁️ Height filter

BDT features a Height Filter rendering system that allows players to filter the visibility of transports, transport pillars, and layout entities (such as sorters, zippers, mini-zippers, and lifts) in the world.

Adjusting the visible height levels makes it significantly easier to inspect and manage multi-tier pipe stacks, layered belt paths, or dense underground logistics without visual clutter. Transports that span multiple levels are hidden/shown based on the majority of their nodes.

• PageUp: increases the maximum visible level (up to level 6, which shows all heights).
• PageDown: decreases the maximum visible level (down to level 0, which shows underground entities only).

These hotkeys can be customized in BDT's mod settings under HEIGHT FILTER. Hidden entities are protected from selection to prevent accidental demolition or interaction.

🚦 Throughput tools

BDT adds a unified Throughput inspector panel for transport entities: belts, pipes, channels, sources, sinks, lifts, balancers, sorters, and connectors. It combines live monitoring with the existing sandbox-only limiter controls, so you can see what a design is actually moving and, in sandbox mode, test how it behaves under custom capacity limits, or measure its output precisely.

The throughput monitor can display averaged flow rates in the world as either:

• absolute throughput in items/min
• percent of the entity's maximum capacity

You can choose how many days each entity should average over, making it easier to smooth out short production bursts or inspect a design's recent behavior.

The in-world overlay can also turn the selected entities themselves into a glowing Throughput coloring (heat map). Instead of only tinting the numbers, BDT lights up the belts, pipes, ports, and layout entities underneath them, so busy lanes and starving lines are visible at a glance even in a dense blueprint test rig.

• Capacity mode colors the entity glow by the entity's maximum transport capacity.
• Relative mode colors the entity glow by how heavily the entity is being used.
• A colorblind-friendly blue/yellow/red palette is available in Mod Settings.
• Near-saturated entities get a stronger pulsing bottleneck glow, making cramped parts of a design easier to spot.

For larger designs, the new Throughput Area Tool lets you drag-select a region and configure throughput display settings in bulk. The default hotkey is Shift+Alt+T.

The area window groups selected entities by type, lets you toggle display visibility per group, and can apply a shared averaging period without closing the window. This is useful when you want to light up a full bus, production block, or testing rig without clicking every belt and pipe one by one.

Throughput limiting remains available in sandbox mode. Limits are saved per entity but are not preserved in blueprints.

This allows you to test your designs thoroughly before capturing the blueprint.

🚧 Legacy Belt Configurations

The Mod Settings menu now features an option to enable Update 1 style transport construction. Turning on "Allow curvy incline belts" permits transports to turn and incline/decline on the exact same tile, restoring the ability to build tight, curvy vertical belts.

Before, U1-style belts were only possible to integrate in modern designs through tedious copy-pasting from an older blueprint or save file.

⚙️ Mod settings

BDT adds a Mod Settings panel, accessible from the top-right M button in the mod menu or with the keyboard shortcut Alt+M.

Markdown table language controls which language is used for table headers and product/entity names when copying Markdown:

Mode	Behavior
English	English headers and names (default)
Local	Current game language
Both	English tables first, followed by local-language tables
Hybrid	Local text first, with English in parentheses where strings differ

Markdown number format controls decimal and thousands separators in copied Markdown:

Mode	Behavior
Auto	English tables use English separators; local and hybrid tables use the current game locale
English separators	Force English separators everywhere
Local separators	Force current-language separators everywhere

Settings are stored per save file. The markdown_table_language and markdown_number_format keys in config.json set the initial values for saves that have no stored settings yet.

The Throughput settings control the global overlay, overlay hotkey, heat-map mode, colorblind-friendly colors, percent display, and the Throughput Area Tool hotkey.
