1. Change a panel input
An engineer changes control load, voltage, motor horsepower, motor count, or a panel option on a placed block instance.
Control panel design software for configurable, logic-driven panel drawings
LogiDraft is for engineering teams that build repeatable control panel systems: control power sections, motor starters, schematic variants, panel outputs, and BOMs that need to change together when requirements change.
Control panel workflows LogiDraft supports
The strongest fit is repeatable panel work where one engineering input affects sizing, schematic visibility, labels, nested assemblies, and structured output data.
| Workflow | Inputs | Resolved Logic | Drawing and Output Result |
|---|---|---|---|
| Control power sections | Control load, incoming voltage, control voltage | Transformer VA, primary fuse, secondary fuse, transformer group count | Control power drawing variants and BOM-style rows update from the evaluated instance |
| Motor starter assemblies | Motor horsepower, voltage, starter options | FLC lookup, breaker selection, contactor sizing, overload range | Starter schematic labels, selected components, and output fields stay coordinated |
| Motor control panels | Motor count, shared voltage, control power needs, pilot/control options | Nested starter assemblies, shared protection, control power sizing | A composed panel can generate coordinated schematic sections and structured outputs |
From input change to drawing and BOM update
A panel variant is evaluated as a system, so the drawing and BOM-style data are not maintained as separate follow-up tasks.
2. Resolve formulas and lookup tables
Local Definitions and Global Blocks evaluate parameters, variables, formulas, lookup rows, states, and nested assemblies.
3. Realize drawing geometry
The evaluated result controls schematic visibility, repeated transformer groups, labels, component geometry, and panel-specific variants.
4. Expose structured outputs
Artifacts and BOM-style rows read from the same evaluated instances that produced the visible panel result.
Where LogiDraft fits in control panel design
LogiDraft is strongest when a team already knows the control panel logic it repeats and wants that logic to live in reusable definitions instead of copied drawings and side spreadsheets.
It is not positioned as a complete replacement for every mature electrical CAD workflow. It is a product-led fit for configurable panel families, reusable assemblies, generated schematics, and outputs that need to follow the same evaluated state.
Panel logic that should not be copied by hand
Control power panel
Control load and voltage can resolve transformer VA, primary and secondary fuse selection, schematic visibility, transformer group count, and BOM output.
Motor starter assemblies
Horsepower and voltage inputs can drive FLC lookup, breaker selection, contactor sizing, overload range, and starter drawing updates.
Nested panel systems
A larger panel can compose multiple starter assemblies with shared voltage, control power, protection, pilot/control options, and structured BOM output.
Local and global reuse
Local Definitions and Global Blocks let teams keep proven panel behavior reusable while still evaluating each placed instance with its own inputs.
Control panel drafting versus evaluated panel systems
Traditional control panel CAD
The drawing is edited first, then notes, spreadsheets, schedules, and BOM rows are checked afterward. That process can work, but repeated variants create drift risk.
LogiDraft control panel model
Parameters, formulas, lookup tables, reusable definitions, nested assemblies, drawings, and artifacts participate in one evaluated panel result.

Questions about this LogiDraft workflow
Is LogiDraft general-purpose control panel design software?
LogiDraft is strongest for repeatable, configurable control panel drawings where inputs and reusable logic can drive schematic variants, component selection, and structured outputs. It is not positioned as a complete replacement for every mature electrical CAD workflow.
How does LogiDraft keep panel drawings and BOMs aligned?
Drawings and BOM-style outputs are generated from evaluated block instances. When inputs change, formulas and lookup tables resolve new values, and both geometry and structured output data read from that evaluated panel state.
Can LogiDraft model reusable panel assemblies?
Yes. Local Definitions and Global Blocks can capture reusable behavior such as starter assemblies, control power sections, or configurable layout pieces, then execute that behavior with different inputs in different projects.
What control panel example should I start with?
Start with the Control Power Panel example if you want to see load and voltage affect transformer VA, fuse selection, drawing geometry, and BOM output. Use the Motor Control Panel example for a larger nested assembly.
Try a control panel system that changes with inputs
Start with the control power demo or inspect the panel examples to see sizing logic, drawing updates, and BOM-style output working from evaluated panel instances.
