Start a new schematic using an electrical template (.dwg) and place catalog components from the symbol library.
Use wire numbering, cross-references, and the PLC I/O tools to connect and document circuits.
Generate BOM / Reports (parts list, wire list) from Project > Reports.
Create panel layouts using component data and place terminal strips, enclosures, and DIN mounting.
Export/print to DWG, PDF or produce fabrication reports.

Full step-by-step tutorial

Prerequisites and installation

Ensure your system meets AutoCAD Electrical 2018 system requirements (Windows, RAM, disk).
Install AutoCAD Electrical 2018 from Autodesk media or download, then run the installation including the symbol and catalog content (content library).
Sign in and activate your Autodesk license (or use a Network license server if provided).
If your company uses standards, copy or configure your project templates, title blocks, and layer standards.

Start a project and set standards

Open Project Manager (AEC Project Manager panel).
Click New Project → choose Standard Project → set project folder and default template.
Set drawing standards (units, lineweights, layers) by opening the template and adjusting settings.
Save the template as your company standard.

Creating a schematic drawing

From Project Manager, right-click → New drawing → select electrical template.
Use the Schematic ribbon: Insert Component, Insert Wire, Insert Connection.
Place components using the Catalog Browser: search by part number or function, then drag a symbol into the drawing.
Use Insert Wire to draw energized wires; AutoCAD Electrical can auto-assign colors and layer based on wire type.
Use Connections tools to create jumpers, splices, and terminals.

Component insertion and catalog

Open Catalog Browser (Library panel) to choose symbols and manufacturer parts.
When you place a component, AutoCAD Electrical associates the drawing symbol with a catalog record (part number, description).
Edit catalog mappings if symbols differ from your database: right-click component → Edit Component → Catalog database mapping.

Wire numbering and cross-references

Use Wire Numbering (Project tab → Edit Wire Numbers) to auto-number wires according to your rules.
Configure wire numbering format (prefix, suffix, starting number) in Project Properties.
Use Cross Reference tools to create automatic references between contacts, coils, and terminal strips.
Run Update Cross-References to refresh all links after edits.

Ladder diagrams and PLC programming support

Use the Ladder Diagram tools for control logic schematics.
Insert PLC modules and use PLC I/O mapping to assign I/O addresses automatically.
Generate I/O lists for the PLC from the PLC I/O Manager.

Panel layout and terminal strips

Create a new drawing for panel layout and import component footprints using Create/Edit Panel Layout.
Use Terminal Strip Editor to arrange terminal blocks and generate terminal drawings and wiring lists.
Place DIN rails, enclosures, and check clearances.

Reports, BOMs and documentation

Open Project → Reports → Generate Report.
Choose report type: BOM (Bill of materials), Wire List, Cable List, Terminal Plan, etc.
Configure report templates (CSV, Excel, HTML) and export for procurement or manufacturing.

Printing and exporting

Use Page Setup Manager to configure paper size, plot styles, title blocks.
Plot to PDF for documentation; export to DWG for sharing with AutoCAD users.
Use eTransmit to bundle all referenced files and reports.

Alternative methods and workflows

Using plain AutoCAD with Electrical symbols

If you don’t have AutoCAD Electrical, you can use standard AutoCAD + third-party symbol libraries, but you’ll lose automated wire numbering, cross-references, and built-in reports.

Upgrading or using a newer version

Consider AutoCAD Electrical 2019+ for improved features and compatibility with newer Windows releases. Migration of projects is usually straightforward but test first.

Using scripts and LISP for repetitive tasks

For bulk repetitive edits (naming, layer changes), use AutoCAD scripts or LISP routines to accelerate work.

Integrating with Inventor or EPLAN

For combined mechanical/electrical workflows, export models to Inventor or use EPLAN for advanced electrical engineering if your project needs specialized features.

Common errors and fixes

Error: “Cannot find Catalog Database”
Fix: Verify the Content Library path in the Options > Content. Reinstall the content or point the software to the correct folder.
Error: Missing Tool Palettes or palettes not loading
Fix: Reset the workspace to default (workspace switching → Reset). Re-enable palettes via View → Palettes.
Error: Cross-references not updating
Fix: Run Update Cross-References and ensure the project database is current. Save all drawings and rebuild the project database.
Error: Wire numbers not consistent
Fix: Check Project Properties → Wire Numbering format and re-run the Wire Numbering utility. Remove manual wire labels before running auto-number.
Error: Symbols display incorrectly or at wrong scale
Fix: Confirm the block insertion scale and your drawing units. Use SCALELISTEDIT and REDEFINE blocks if necessary.
Error: License or activation problem
Fix: Verify internet connection and Autodesk account credentials. If using network license, check the license server and port.
Slow performance in large projects
Fix: Use XREFs, purge unused objects (PURGE), run AUDIT, and consider splitting very large projects into subprojects.
Error exporting reports / BOM missing items
Fix: Check that all components are mapped to catalog records and that Report template filters include the desired component types.

Practical tips and best practices

Always start with a project so drawings share the same database and reports are accurate.
Use company templates for title blocks, layers, and plot styles to ensure consistency.
Keep the symbol library and catalog up to date; match symbols with real part numbers.
Use XREFs for repetitive hardware like enclosures and panel outlines to save file size.
Regularly run PURGE and AUDIT to keep files clean and reduce corruption risk.
Use Incremental Save and maintain backups—store copies in versioned folders or a source control system.
Use layer naming conventions (e.g., E-WIRE, E-SYMB) so visibility can be controlled easily.
Document your wiring rules in a project README for consistent wire numbering and cross-reference rules.
Learn and use keyboard shortcuts for frequent commands (INSERT, WIRE, PLCIO, REPORTS).
Test report templates with sample projects to ensure the generated CSV/Excel matches procurement needs.

FAQ

How do I migrate projects from AutoCAD Electrical 2018 to a newer version?

Use the newer version to open the project; it will prompt to upgrade. Backup your project first. Check custom templates and symbol mappings after migration.

Can I use AutoCAD Electrical 2018 on Windows 10/11?

AutoCAD Electrical 2018 runs on Windows 10 (check Autodesk compatibility notes). For Windows 11, verify compatibility or use newer AutoCAD Electrical versions recommended by Autodesk.

Why aren’t my wire numbers updating automatically?

Make sure the wires are not manually labeled. Configure wire numbering rules in Project Properties and run the Wire Numbering utility on the project.

How do I add a custom symbol and link it to the catalog?

Create the block in the symbol library, then open the Catalog Browser and add an entry mapping the block name to the catalog record (part number & description).

How do I generate a Bill of Materials (BOM) with manufacturer part numbers?

Ensure every component placed has a catalog entry with manufacturer part number populated. Then use Project → Reports → BOM and Export to Excel or CSV.

My cross-references show broken links after moving files — how to repair?

Use Project Manager to re-path drawings or use Reference Manager to correct XREF paths. Then run Update Cross-References.

Is it possible to automate repetitive tasks in AutoCAD Electrical 2018?

Yes — use scripts, AutoCAD LISP, or the Action Recorder for repetitive sequences. Some tasks can also be automated via the Reporting tools and batch processes.

Can I share drawings with users who only have standard AutoCAD?

Yes. Export or save as DWG. Standard AutoCAD users will see the drawing geometry but will not have AutoCAD Electrical’s metadata-driven features (wire lists, BOM generation) unless the metadata is preserved in layers/attributes and compatible reports are exported.

What is the best way to maintain symbol and catalog consistency across a team?

Keep a central content library on a shared network location and standardize templates. Use controlled updates and versioning for symbols and catalog databases.
