CADmep Fabrication

This page introduces the basics of CADmep fabrication workflows. It is designed for users who need to understand how fabrication content, services, reports, numbering, and outputs fit together in a controlled MEP detailing process.

1. What CADmep fabrication is

Start here

CADmep fabrication is a workflow used to create fabrication-intent MEP content for ductwork, pipework, and related systems. It is not only drawing geometry — it is working with controlled items, services, and data so that the model can support reporting, numbering, spooling, and downstream manufacture.

Item-based

CADmep uses fabrication items rather than only generic drafting objects.

Database-driven

The quality of the database and content strongly affects the workflow.

Output-focused

The model supports reports, numbering, spools, and other fabrication deliverables.

2. Profile and database basics

Before modelling starts

Good fabrication work starts with the correct environment. If the wrong profile or wrong database is active, the rest of the workflow becomes less reliable very quickly.

Check these first
  • Correct CADmep profile
  • Correct fabrication database path
  • Correct project content source
  • Correct setup for the intended workflow
Why this matters
  • Reduces content inconsistency
  • Improves report quality
  • Supports repeatable modelling
  • Reduces downstream rework
Warning: Users often try to model around poor setup. That usually creates bigger problems later in reports, numbering, and outputs.

3. Services and ITM content

Core content structure

Services and ITM content are central to CADmep. Services control what users can place, and ITM files control the behaviour of the fabrication items being used.

Services

  • Control available item selections
  • Support consistency across users
  • Should follow project standards

Service templates

  • Should be controlled and approved
  • Need to reflect the intended workflow
  • Should not be changed casually

ITM files

  • Define fabrication items
  • Influence reports and outputs
  • Need to be organised and maintained

4. Fabrication modelling basics

Model with purpose

Fabrication modelling in CADmep should be done with downstream outputs in mind. The user should think about consistency, connectivity, and how the selected items will behave in reports and spools.

Good modelling practice
  • Use approved services
  • Use consistent items for similar conditions
  • Maintain clear connectivity
  • Think about report and spool behaviour as you model
What strong modelling supports
  • Cleaner reports
  • Better numbering
  • Clearer spool output
  • Better communication to manufacture and installation

5. Numbering and reports

Data and outputs

Numbering and reports are some of the most important downstream functions in CADmep. They depend on consistent modelling and a clear understanding of what makes one item the same as or different from another.

Numbering logic

  • Should be agreed early
  • Should reflect consistent item use
  • Should avoid unnecessary variation

Reports

  • Support delivery information
  • Can also be used as QA tools
  • Need checking before issue

Output quality

  • Depends on content quality
  • Depends on model consistency
  • Should not be assumed correct without review

6. Spooling and outputs

Downstream deliverables

Spooling and export outputs should happen at the right point in the workflow. If the model is still unstable, releasing spool or export information too early can create unnecessary rework.

Before spooling or export
  • Check content consistency
  • Confirm numbering logic
  • Review coordination status
  • Check the intended scope carefully
Do not rush outputs
  • If the model is still changing heavily
  • If content is inconsistent
  • If numbering rules are unclear
  • If scope boundaries are not agreed

7. QA basics

Check before issue

QA in CADmep is not only about checking a finished report. It should begin with the profile, database, services, and content before the user moves on to modelling, numbering, and outputs.

Setup QA

  • Correct profile
  • Correct database
  • Correct services

Model QA

  • Consistent items
  • Clear connectivity
  • Stable enough for outputs

Output QA

  • Reports reviewed
  • Spools reviewed
  • Exports validated

8. Common beginner mistakes

Avoid these early
  • Starting with the wrong profile or database
  • Using uncontrolled services or content
  • Mixing inconsistent items for similar conditions
  • Ignoring numbering logic until late in the workflow
  • Spooling unstable information too early
  • Assuming report problems are only report-command problems
  • Trying to work around setup problems manually
Important: In CADmep, many workflow problems begin upstream in content and setup, even if they only become obvious at output stage.

9. Do / Don’t guidance

Quick reference

Do

  • Use the approved profile and database
  • Use controlled services and ITM content
  • Model consistently
  • Think about numbering and reports early
  • Check outputs before issue

Don’t

  • Let users create their own uncontrolled workflows
  • Ignore content problems until report stage
  • Use inconsistent items casually
  • Spool unstable content too early
  • Assume automation will fix poor modelling
Final takeaway: CADmep fabrication basics are really about controlled content, consistent modelling, and understanding how the model drives the outputs. If the setup and standards are right, the workflow becomes much more reliable.
