Interactive models of substations, power plants, LNG facilities, refineries, offshore platforms, data centers and communication towers, plus trainers for BIM management, CAD design and engineering fundamentals. Click any part to see what it is and what it does, open the drawings linked to the model, and work through the training tools each trainer offers. Everything runs in the browser.
Build a substation in 3D from a template, a generated arrangement or a laser scan, then generate drawings, DXF files, a bill of materials and schedules. Outputs are screening level and not PE-sealed.

Training models only. Not for design, construction, operation, climbing, well control or emergency response.
Not prepared, checked or sealed by a licensed Professional Engineer.
Not accredited, not offered for PDH credit, not a certification, and not affiliated with any exam board, licensing board or software vendor.
Facilities are generic. Dimensions and ratings are representative of common practice, and values no public source fixes are labeled as model values.
Wireframes on this page are schematic and not to scale.
Each trainer is a separate site with its own terms of use. Its About page lists its references, the editions used and its limits.
Tools in the trainers
Tools differ by trainer, and some are still being built. Each trainer shows the ones it has under Learn.
Identify any partClick a component to see its name, what it does and how it is built.
Drawings linked to the modelOpen the one-line, plans, elevations and other drawings that go with the model.
Guided tour and quizWalk through the facility in order, then test what stuck.
Trace a tripFollow a fault through protection and control to the breaker that clears it.
Switching and lockoutLearn the concepts behind switching and isolation. Real switching follows your employer’s procedures and switching orders.
Clearances and approach distancesMeasure working clearances and distances to energized parts.
Arc flash, step and touch voltageSee teaching-level estimates of the electrical hazards around the equipment.
Walk the siteDrop to eye level and walk the yard, the plant or the deck.
X-ray and labelsSee through enclosures and label every component in view.
Bill of materials and cable scheduleExport quantities from the model as CSV.
How the models are built
Steel comes from published shape tables. Pipe, flanges, conduit and cable tray use catalog dimensions. In the electrical trainers, phase spacing and live-part heights follow the voltage class.
Where no public source fixes a number, such as a rating or a process condition, the trainer labels it as a model value instead of presenting it as fact.
Use them to bring new hires up to speed on how a facility fits together and what each part is called.
