What is LogiDraft?
LogiDraft is a full 2D drafting workspace. It adds a parametric layer with Excel-style formulas and reusable blocks to automate repetitive work.
You can use it like normal CAD, or turn repetitive designs into systems.
Who it's for
- People who draft normally today but redraw repetitive designs
- Engineers who maintain templates and spec-driven drawings
- Anyone who wants drawings to stay consistent as requirements change
What problem does LogiDraft solve?
Traditional drafting requires repeated manual edits when requirements change. In electrical and automation projects, a single sizing update can ripple across dozens of schematics, schedules, and labels. Those changes are time consuming and error prone because the logic often lives in engineers' heads or in separate spreadsheets.
LogiDraft addresses that gap by treating drawings as computed outputs. Parameters and formulas become the source of truth, so updates propagate across the entire drawing set. This approach reduces duplicated logic, eliminates manual recalculation, and supports consistent CAD automation in engineering workflows.
How LogiDraft works (high-level)
LogiDraft stores parameters as structured data and lets you apply Excel style formulas in CAD to drive dimensions, symbols, and annotations. Blocks are defined with inputs and rules, so when a parameter changes the block recalculates its geometry and text.
The engine evaluates formulas, recalculates rule based CAD blocks, and updates dependent drawings. That means a change to a control voltage, transformer selection, component selection, or I/O count can cascade through panel schematics, wiring diagrams, layout sheets, and annotation schedules without manual redrafting.
- Parameters represent engineering inputs such as ratings, counts, and options.
- Excel style formulas compute derived values used in drawings and notes.
- Parametric blocks recalculate geometry, annotations, and symbols.
- Cascading updates keep drawing sets consistent as requirements change.
How LogiDraft is different from traditional 2D CAD
LogiDraft is an automation-first alternative to manual drafting workflows. Tools like AutoCAD are excellent for direct drawing, but they are optimized for manual edits rather than formula based automation. LogiDraft focuses on parametric logic, which makes it a practical AutoCAD alternative for automation-heavy engineering teams.
- Manual redraws versus formula recalculation for updates.
- Static blocks versus rule based CAD blocks that adapt to inputs.
- Geometry as lines versus geometry as data that can be validated.
Example automation use cases
Automated transformer sizing in electrical schematics
In LogiDraft, transformer sizing automation can be modeled as parameters and formulas tied to load, voltage, and utilization factors. When an engineer updates a load value, the transformer selection updates automatically and the schematic symbol reflects the new rating.
This workflow supports automated electrical schematics that stay aligned with calculation logic. Instead of rechecking multiple sheets, LogiDraft recalculates the sizing logic and updates the drawing outputs in one pass.
Parametric electrical control diagrams
Control diagrams often repeat patterns across panels and machines. LogiDraft lets teams build parametric 2D CAD symbols and panels that change with parameters like I/O counts, safety circuit options, or motor starter types.
Each control diagram becomes a structured template with Excel style formulas in CAD. When a parameter changes, the control drawing recalculates and updates across sheets, enabling consistent CAD automation without manual redrafting.
Reusable engineering block libraries
LogiDraft supports reusable block libraries where each block encodes engineering rules rather than static geometry. A block for a relay bank, for example, can expand or contract based on channel counts and wire labels.
This approach turns blocks into formula driven CAD modules that can be reused across projects. It accelerates engineering drawings automation because teams update parameters instead of recreating block layouts.
Rule-based drawing variants (options, configurations)
Many products ship in multiple configurations with slight variations in wiring, components, or labels. LogiDraft can encode those options as rules and parameters, then generate the correct drawing variant automatically.
This rule-based approach reduces manual variant management and ensures each configuration is derived from the same formula driven CAD logic. Engineers can trace how a parameter affects geometry, annotations, and symbols.
Configurable layouts and templates across disciplines
Engineering teams often maintain standardized drawing templates for layouts, equipment schedules, or interface sheets. LogiDraft can drive those templates from shared parameters so sheet content, labels, and callouts update from the same rule set.
This use case applies beyond electrical domains by treating drawings as configurable outputs. When options change, LogiDraft recalculates geometry and annotations automatically, ensuring consistent rule-based drawings across projects.
Fast iteration on engineering changes
When an engineering change order arrives, teams usually update many drawings and recheck references. LogiDraft treats those changes as parameter updates, so dependent drawings can be regenerated consistently.
This makes LogiDraft a cloud based CAD for engineers who need fast iteration and reliable updates. The formulas act as a single source of truth, reducing errors caused by mismatched revisions.
What LogiDraft is not
LogiDraft is not a 3D mechanical CAD tool. It focuses on parametric 2D CAD for engineering drawings rather than solid modeling or advanced 3D assembly workflows.
It is also not a generic drawing app. LogiDraft is purpose-built for formula driven CAD and CAD automation, which makes it a specialized tool for engineering workflows that benefit from rules and recalculation.
FAQ
Can I use LogiDraft for regular 2D drafting?
Yes. Manual drafting tools are fully supported.
Do I have to use parametrics?
No. Parametrics are optional, and you can adopt them gradually.
Can I export to standard formats?
Yes. DXF import and export are supported.
Is LogiDraft an AutoCAD alternative?
LogiDraft is an AutoCAD alternative for automation-first workflows. It is not a drop-in replacement for manual drafting, but it is built for teams that need formula-based updates, rule-driven blocks, and repeatable drawing logic.
Does it support formula-driven blocks?
Yes. LogiDraft uses rule based CAD blocks with parameters and Excel style formulas, so a block can recalculate its geometry and annotations when input values change.
Can I build automated electrical schematics?
Yes. LogiDraft is designed for automated electrical schematics where symbols, labels, and schedules update from formulas and shared parameters across drawings.
Does it handle transformer sizing automation?
It does. Transformer sizing automation can be encoded as formulas tied to load, voltage, and utilization factors so schematics update when sizing inputs change.
Is LogiDraft a 3D CAD tool?
No. LogiDraft focuses on parametric 2D CAD for engineering drawings and does not provide 3D solid modeling or mechanical assembly features.
Who is LogiDraft for?
It is for engineers and technical teams who rely on formula-driven CAD and need rule-based or configurable drawings with consistent updates. Electrical and automation teams are common examples, but the workflow applies to any group managing parameterized 2D drawing sets.
