One connected workflow

The schematic is the calculation model

Gas pipe sizing is often spread across disconnected tools: a drawing in one program, loads in a spreadsheet, results copied back onto the sheet. Change one appliance and it is hard to know whether the drawing, calculation and report still match.

Before

Disconnected tools

Change the network and several files need checking again. Plenty of room for errors.

With Schematic Studio

One model

Change the network and the calculations and report change with it. Nothing to copy or reconcile.

SchematicCalculationReportChange once. Everything updates.

Purpose-built drafting

Not a CAD platform with a calculator bolted on

Schematic Studio is designed specifically for gas reticulation schematics. No command line to memorise and no maze of menus. Draw the network, enter the information, calculate the system and issue the result.

Draw and connect

Clean, connected pipework, fast

Draw pipework directly on the canvas and connect runs to sources, branches and appliances. Pipes snap to endpoints, centrelines and crossings, while angle snapping makes standard 45° and 90° connections straightforward.

Product capture placeholder01

Short capture: draw a run with endpoint and 45° snapping

Edit without redrawing

Layouts change. Your drawing keeps up.

Move nodes, reshape runs, adjust branches, rotate appliances and reposition tags while the underlying network stays connected. Connections, loads and tags carry through as the layout changes.

Product capture placeholder02

Short capture: move an appliance and keep every connection

Update in bulk

Variations without the busywork

Select groups of pipes, appliances or tags and change shared properties in one action. When loads change across a set of appliances, edit them together and recalculate the pipe sizing automatically.

Product capture placeholder03

Short capture: bulk-edit appliance loads and recalculate

A schematic that understands the network

Calculate every connected pipe. See it on the drawing.

Assign loads in MJ/h, apply diversity where appropriate and calculate the whole connected system in one action, not run by run in isolation. Results display directly on the schematic.

Pipe sizesGas loadsCapacities and spare capacityRun and index lengthsDesign inputsCalculation findings

Update an appliance, route, load or parameter and recalculate the network in seconds. The assumptions behind every result, including gas type, supply pressure, allowable pressure drop, pipe material and index lengths, stay recorded with the project so you can always see how a size was produced.

Find problems before issuing

Checks before the report leaves the building

A reliable result depends on the network being connected, the inputs being complete and the assumptions being documented. Schematic Studio checks the project before the report is generated and separates what must be fixed from what needs professional consideration.

Critical blocks the report Warning review required Advisory for consideration

Professional judgement remains with the professional. Schematic Studio supports the calculation and documentation process. It does not replace the responsibility of a suitably qualified person to review the design and confirm the installation is suitable.

Professional reports

Two documents. One source.

When the design is ready, generate the documents needed for review, coordination and issue from the same connected model used to draw and calculate the schematic. Control tags, fields, fonts, colours, sheet sizes and title information to suit the project.

Engineering calculation report

A structured record of project details, design inputs, network results and findings. A clear professional record of how the network was assessed, ready for technical review.

Schematic drawing sheet

A clean visual schematic for coordination, construction or the project drawing set. Export from A0 through A4, with control over how the drawing appears on the page.

Traceable from drawing to report

Every report tied to the drawing that produced it

When the network is calculated, a locked snapshot captures the drawing, engineering inputs and results as they existed at that moment. If the working drawing changes later, the issued report remains matched to the exact project state that created it.

Working

Built for Australian gas projects

From first sketch to project record

Natural gas and LPG. Australian units, terminology and conventions. From a small single-level system to a larger multi-level network, the workflow stays consistent.

How it works

Five steps from blank canvas to issued documents

01
Draw the network
Place the source, draw the runs and connect the appliances across one or multiple levels.
02
Enter design conditions
Set gas type, supply pressure, pressure drop, material and loads. Apply diversity where appropriate.
03
Calculate the system
Size every connected pipe in one action, then review capacities and the index run.
04
Resolve findings
Correct disconnected pipework and incomplete inputs before issue.
05
Export the documents
Create the calculation report, drawing sheet or both, tied to the project state that produced them.

Why professionals use Schematic Studio

Less reconciling. More engineering.

One connected project

Schematic, inputs, calculation and report come from the same model.

Whole-network sizing

Every connected pipe is calculated in one action, with revisions completed in seconds.

Built for Australia

AS/NZS 5601.1:2022 workflows, Australian units and familiar terminology.

Clear project checks

Critical omissions and disconnected elements are caught before issue.

Traceable reporting

Every report is matched to the exact drawing and inputs that produced it.

Cloud-based access

Built for collaboration

One project source for the whole team

A contractor prepares the schematic. A designer confirms the layout. An engineer reviews the calculations. A project manager needs the final report. Everyone works from the same current cloud project, not separate copies emailed back and forth.
