EasyCAS, lesson by lesson

The help inside the program explains every button. This guide puts them in order: each lesson builds a piece of a real compressed-air network, from the first symbol on the sheet to the audit report you hand to the customer.

Lessons

1 Your first scheme An open pipe on a compressor: two items, a few numbers, and what it costs a year. 15 min
2 Finding your way around The sheet, the data panel, the status bar and what each of them is for. 10 min
3 Choosing catalog items The tree, the filter, favorites, the item card and the list of replacements. 15 min
4 Connections and layout Automatic routing, hand-drawn polylines, groups, snap. 25 min
5 Captions, live values, pictures Text that reads a result out of the scheme, conditions, Rename ID, a plant layout under the scheme. 25 min
6 Input parameters and units What drives the yearly money, normal versus actual flow, presets, a unit for one row. 20 min
7 Calculating a design scheme A main, a tee, two branches: where the pressure goes, checked by hand. 30 min
8 Problems and sizing The Problems panel, pressure profile, Size pipe, variant calculation, thresholds. 30 min
9 Ring mains and compressors Closing a ring with LOOP, reverse flow, compressor selection, rooms and several compressors. 40 min
10 Setting up an audit From the compressor to the consumers: the setting, utilization, the lowest setting, artificial demand, the leak test. 35 min
11 Logger measurements A gauge and a flow meter on the network, a week of logger records, the measured power and the model scaled to it. 40 min
12 Measures and payback Scenarios as is and as it will be: applying measures, a regulator, a leak repair, the comparison and the payback. 35 min
13 Zones and department costs A compressor room and two lines drawn as zones: live totals, formulas in labels, the bill split by department. 25 min
14 Cyclogram and work cycle A one-minute round of two consumers: the peak, the mean, the cost of a round, the cycle as text and as a file. 30 min
15 Pressures in time The Dynamic mode: one second of the network millisecond by millisecond, the results window, a compressor that cannot keep up. 30 min
16 The PDF report The full report of a design, the one-page air data sheet of a machine, the audit report with the cost by department. 30 min
17 Visio, web, spreadsheet A Visio drawing with live connectors, the scheme on the web, the tables of EasyCAS in a spreadsheet. 25 min

How to use it

Work with EasyCAS open beside the guide. Every lesson ends with a scheme you can check against the figures, and starts from the file the previous one left behind.

Press / to search the guide. The lessons are a path, not a reference — read them in order the first time.

Looking for one control?

That is what the help in the program is for. Point at the button, panel or table you are unsure about and press F1 — the topic for the control under the pointer opens, without clicking it first.

Where a lesson relies on a topic, it carries a mark like so you know which one to open. Every key and mouse action is on one page in Hotkeys and mouse, and the words of the program in the Glossary.
