Variant drawing automation

A thousand drawing variants.
Not one hour of redrawing.

A new order lands: same conveyor, 400 mm longer, motor on the opposite side. Someone opens last month's DWG and starts editing — 4–8 hours per variant, order after order. Those edits follow rules that never change. We build the rules into parametric master templates, and the next variant generates itself in minutes.

The problem

Your engineers are redrawing decisions they already made

Every new order restates the same engineering — same rules, new dimensions. Restating it by hand is slow, it invites errors, and it's what your most experienced people spend their week on.

Drafting by hand

The routine never changes: copy the last job, edit, check, hope.

  • 4–8 hours per variant. An afternoon of senior time spent moving dimensions a rule could move.
  • Mistakes hide until it's expensive. A stale dimension slips past review and turns up on the shop floor as rework.
  • Your best people are typing, not thinking. The engineer who could design your next product is updating title blocks instead.
Rules doing the drafting
  • Decide once, run forever. The if-this-then-that in your engineer's head becomes explicit rules inside a master template — no one re-derives it per order.
  • The CAD edits itself. Geometry, dimensions, views, and annotations update inside Inventor, SolidWorks, or AutoCAD — no parallel system to babysit.
  • The whole package ships together. Drawings, BOM, and PDFs fall out of a single run, already in your title blocks and standards.

ONE TEMPLATE · EVERY VARIANT · NO REDRAWING

Results

What changes when rules do the drafting

90%

Faster turnaround

Generation drops from hours to minutes per order — same-day drawing packages become the norm.

ZERO

Drafting errors downstream

Rule validation catches bad configurations before a drawing exists, not after it ships.

10×

Volume, same headcount

Variants scale with compute, not with people. 100 orders or 1,000 — the effort is the same.

Process

How variant drawing automation works

Three moving parts, built in this order: your models, your rules, your outputs.

STEP 1

Master templates

We convert the models you already have into parametric masters that carry the geometry, dimension, and view logic for the whole product family. No remodeling from scratch.

STEP 2

Rule engine

Your selection, validation, and calculation rules run against every configuration before anything is drawn — invalid combinations never reach CAD.

STEP 3

Output generation

Each variant generates its full manufacturing package — in your title blocks, to your standards, ready for the shop floor.

Platforms

Built inside the CAD you already run

Nothing new to buy, nothing new to learn. The automation lives in your existing seats and speaks each platform's native API.

Use cases

Where drawing variants pile up

Products that come in sizes

  • Fabricated products cut and welded to order
  • Machinery sold with modular options
  • Sheet-metal parts and assemblies
  • Industrial equipment in fixed configurations

Documents owed on every order

  • Sales and proposal drawings
  • Order-specific manufacturing prints

Who it's for

Is drawing automation a fit for your team?

The strongest candidates share one trait: their drawings differ in numbers, not in kind.

Engineering & drafting teams

Every request on the board reads "same as last time, but…" — a new size, a new option, a new customer spec, drafted by hand.

Steel & building products

Hundreds of sizes of the same profile, bracket, or panel, all governed by the same span tables and rules.

Industrial equipment manufacturers

Standard machines with parametric options — and every sale means another full GA package.

Teams quoting late

Manufacturing waits on drawings, drawings wait on engineers, and the backlog has become the schedule.

FAQ

The questions we get on every first call

Does this work with my existing CAD models?
Usually, yes. If your models are already parametric and reasonably clean, we convert them into master templates rather than remodeling from scratch. Where a model is too tangled to drive reliably, we rebuild just that part — not your whole library.
What software do I need?
One licensed seat of your CAD platform (Inventor, SolidWorks, AutoCAD) running as the generation machine is usually enough. The people requesting drawings don't need CAD licenses at all. We advise on the exact mix during the audit.
Can I connect this to my ERP?
Yes. Generated BOMs can push straight into SAP, NetSuite, Odoo, or Microsoft Dynamics — so the same run that produces the drawings also creates the data purchasing and production work from.
How long does implementation take?
Plan on 3–6 weeks for a pilot covering one product family. Wider rollout depends on how many families and rule sets you have, but most clients see the system pay for itself within 6 months.
