Inventor iLogic Automation Development

We build robust iLogic master models, rules and forms, so engineers can configure parts and assemblies by choosing options instead of editing features, and still understand and maintain the logic themselves.

Rule-based design your team can own

iLogic is Inventor's built-in rules engine. Rules are written in VB.NET-based code and can drive parameters, suppress features, swap components, update iProperties, change drawings and export files. iLogic forms give engineers a simple input screen, so a new variant can be produced by entering sizes and choosing options.

The difference between an iLogic setup that lasts and one that breaks is structure. ENGIMANDI designs clean master models with stable references, separates rules by responsibility, stores shared logic in external rules, and documents what every parameter does. We avoid fragile tricks and test every combination of options, so the model does not fail when someone picks an unusual size.

Capabilities

iLogic automation we deliver

From single configurable parts to full product configurators.

Configurable Parts

Parameters, feature suppression and materials controlled by rules and tables.

Configurable Assemblies

Component swapping, patterns, constraints and visibility driven by options.

iLogic Forms

Clean input screens with option lists, validation and grouped parameters.

Excel-Driven Rules

Standard sizes, lookups and engineering tables kept in Excel for easy updates.

Drawing Rules

Views, sheet formats, notes and parts lists updated to match the configured model.

Rule Repair

Audit and fix slow or broken iLogic setups built by others.

FAQ

iLogic questions

Can our engineers maintain the rules?

Yes. That is a key advantage of iLogic. We keep rules readable, documented and organised so engineers can add sizes and options.

How do we create a new order from the master?

We add a save-as or Vault Copy Design step that creates a unique copy of the configured assembly and drawings for each order.

When is iLogic not enough?

Very large assemblies, complex UI, integration with other systems or strict performance needs are better served by an add-in on the Inventor API.

Can you fix an existing iLogic model?

Yes. We audit rules, remove duplication and fix fragile references that cause errors.

Does iLogic work with Design Automation?

Yes. iLogic rules can be run by Design Automation for Inventor for web configurators.
