PDM-LITE · CATALOG · PROTOTYPE

Mechanical parts, from drawing to data.

Mech.TriD is a technical catalog with PDM functions for parts designed in SolidWorks and Inventor. Every part has its 3D model, drawing, data sheet and history; releases are checked, changes are controlled, and the design process is measured.

A two-minute tour of the working prototype, from log-in to the dashboard.

01

One place for every part, its data and its changes

The catalog covers the path a mechanical part follows in a small technical office: classified, modelled, drawn, assembled, checked, released and changed under control.

Catalog

ICS classification
Families and categories of ISO ICS 21 for mechanical components.
Search by code
Type a part number and press Enter: the part opens at once.
QR on every drawing
A QR code in the title block opens the part from a phone on the shop floor.

Engineering

3D viewer from STEP
Volume, mass from material density and envelope computed from the exact geometry.
Multi-level BOM
Assemblies inside assemblies, structured BOM with level codes, flattened BOM for ordering.
Cut list
Bars per profile with a cutting plan per bar, sheet parts and parts to buy.

Control

Lifecycle and release check
Draft, In review, Approved, Released: nothing is released while a component is not ready.
Check-out and check-in
One person edits a part at a time; everyone else sees it read only.
Engineering changes (ECR)
Reason, approval, new revision and closure, with a signable form.

Analysis

Lean dashboard
WIP, lead time, first pass yield, throughput and a cumulative flow diagram.
Change control with SPC
Pareto of change causes and an I-MR control chart of the ECR cycle time.
Data quality
Automatic checks and a completeness matrix of the technical data.

Platform

Log-in and roles
Viewer, designer, approver, administrator; hashed passwords; four-eyes approval.
Audit trail
Every change signed with user, date and comment; exportable for an ISO 9001 audit.
Five languages
Italian, English, French, German and Spanish, reports included.
02

Screens from the working app

Demo data: twelve example parts, two assemblies and a marked demo history. The example drawings carry a SAMPLE ONLY watermark.

A release you can trust, a change you can trace

Designers draft and send to review; only approvers can approve, release or mark a part obsolete. A released part is never edited in place: it changes through an ECR and a new revision.

Lifecycle: Draft, In review, Approved, Released; changes through an ECR create a new revision in Draft Draft In review Approved Released back to Draft · comment required ECR approved › new revision in Draft · old revision Change pending until the new one is released designerapproverapprover+ release check
Release checkEvery component of an assembly, at every level, must be ready: drawing, data, status.
Check-outOnly Draft, Prototype or On hold parts are edited, one person at a time.
Audit trailEach step is signed with user, date and comment, and can be exported.

About the project

More than a drawing.
More than a database.

Every part tells two stories: the one on the drawing and the one in the data. Mech.TriD keeps both in one place. It is a digital catalog that links every drawing to its 3D model, its revisions and its approvals, then turns that history into insight: where the design process slows down, why parts change and how complete the technical data really is.

What gets measured gets improved. Bottlenecks become visible, changes are traced back to their root cause, and every release is backed by evidence instead of memory.

Mech.TriD is a working prototype: every feature shown on this page runs in the app today, and development continues.

The name says it: Mech for mechanics, Tri-D for 3D and for the three D's of the work, Draft, Design and Data.
