NB Engineering Tools v6.0

Structural & Engineering Design Tools for AutoCAD

Connect AutoCAD for online activation and token refillsNB Credit prices & payment guide

A professional AutoCAD automation suite for footing, combined footing, pile cap, beam, slab, column, grid and geotechnical workflows. Works from the Ribbon and the classic pull-down menu alike.

Compatibility: Per the published product document, the current commercial build targets on Windows 10/11 64-bit.

Compatibility with other AutoCAD versions must be confirmed separately. No version is called tested without evidence of a runtime test.

One AutoCAD workflow for structural engineering

NB Engineering Tools brings structural drawing, reinforcement detailing, foundation workflows, quantity estimation and layout preparation into AutoCAD. It is designed for civil and structural engineers, consultants, drafting professionals and design offices. A dedicated ribbon and pull-down menu provide access to the compiled tools without loading individual LSP files.

Footing design, reinforcement, drawing and estimate

NBFooting combines footing selection, unique design grouping, structural inputs, design summaries, reinforcement, plan and section drawings, and estimates. Repeated identical footings can be organised as a unique design group. For example, 24 selected footings representing two unique designs are charged according to the successful unique-design policy, rather than as 24 separate designs. NBCombinedFooting provides a separate combined-footing workflow.

Pile cap geometry and reinforcement

NBPileCap organises pile-cap geometry, loads and reinforcement inputs. Depending on the module version, workflows include compression and tension inputs, concrete and steel properties, thickness and shear checks, moment reinforcement, development/STM review, estimates, and plan/section drawings. Compact interfaces help organise these inputs on laptop displays.

Slab, beam, grid and room measurement

NBSlabDraw helps automate main, crank and extra reinforcement, support detection, block reading, hooks, bends and legend dimensions. Beam, grade-beam, column and grid modules support related drawing and layout tasks. NBRM adds room names and architectural feet-and-inch measurements, such as a bedroom measuring 15′-10″ × 8′-11″.

Licensing, Machine ID and tokens

Machine activation

Each supported computer generates a Machine ID, and the licence is bound to it.

NBM-XXXX-XXXX-XXXX-XXXX-XXXX-XXXX

Token / credit

Activation grants the right to use the software; a token is credit for running a specific paid operation. An active licence still needs enough tokens for a paid operation.

How tokens are spent

  • Token cost is not the same for every tool.
  • Some tools charge per successful command session.
  • Some design tools charge per successful unique design — selecting 24 footings that resolve to 2 unique designs is charged as 2.
  • A cancelled or failed operation may not be charged, depending on the tool.

Windows reinstall or format: Local licence and token data may be erased. If the balance reaches zero there is no guarantee the previous tokens return automatically.

A clear screenshot taken no more than 30 minutes before the Windows setup may, after vendor verification, allow the remaining balance to be reissued. For the full conditions and exceptions see the licence recovery page.

Activation, credits and updates

Activation permits use on the licensed machine. Tokens are separate usage credits for paid operations; an active licence may still require a token refill. Custom refill amounts are subject to vendor approval.

Check your Machine ID and License ID before purchasing a refill. Under the product policy, a valid refill that has been issued and successfully applied is generally non-refundable. Replacing a refill issued against incorrect information requires vendor verification.

Moving to another computer or changing major hardware may change the Machine ID. Activation and remaining-credit transfers require verification of identity, the previous licence and purchase records; they are not automatic.

Updates may improve the interface, engineering workflows, security and compatibility. Major releases, additional AutoCAD version support or significant new modules may require a paid upgrade.

Frequently asked questions

Can NB Engineering Tools be used without AutoCAD?
No. The current version is an AutoCAD-based engineering productivity suite.
Which AutoCAD versions does it support?
The current commercial build is made for AutoCAD 2024, 2025, 2026 and 2027, in a Windows 10/11 64-bit environment. AutoCAD 2020–2023 and earlier are not supported. Which releases have completed runtime testing is stated separately.
Does the software run on Windows 11?
Yes. The current target environment is Windows 10/11 64-bit.
Is there footing design?
Yes. NBFooting supports an isolated footing design/drawing workflow, and there is a separate module for combined footings.
Is there pile cap design?
Yes. The NBPileCap module supports a pile-cap design/drawing and reinforcement workflow.
Can it draw slab reinforcement?
Yes. NBSlabDraw is made for slab reinforcement automation.
What is a token?
A token is credit for using a specific paid operation in the software.
Can I buy a custom number of tokens?
Yes. A vendor-approved custom token refill can be issued.
Do tokens survive a Windows reinstall?
Reinstalling or formatting Windows can lose the local token data. If the token count reaches 0, standard policy is that new tokens have to be bought.
What if I have a screenshot of the token balance from before the reinstall?
If you have a clear, verifiable screenshot taken no more than 30 minutes before the Windows setup, the remaining balance shown in it may be reissued after vendor verification.
And without a screenshot?
Tokens are not restored free of charge; new tokens have to be bought.
What if I only uninstall AutoCAD?
If only AutoCAD is uninstalled and the NB licensing data in Windows is left intact, the activation and the tokens usually remain.
Does an engineer have to check the software’s output?
Absolutely. NB Engineering Tools is an automation and productivity aid; the final engineering responsibility rests with the qualified engineer.

Engineering responsibility: The software provides design and drawing automation, but the final engineering decision, design verification, code compliance, structural safety and drawing accuracy remain the responsibility of a qualified engineer. No automated result should be used as a final construction decision without independent engineering review.
