To make a design, you usually first open a floor plan image with the Design -> Plan -> Open plan image button. Then you immediately use the Plan -> Set scale tool (set scale tool) to set the image scale. If you don't have an image, or want to modify the design on the image, you can sketch a plan with the drawing tools in the Design -> Draw toolbox. Next, you would you define load zones by using the Set Load Zone tools on the Loads tab. You can set the heat load by specifying the power per floor are to use (in kW/m2, say) for these tools. The heat load can be adjusted individually for each zone, if required. Alternatively, by using the context menu item Set zone load on a zone you can directly set its total load if you prefer.

Once you have your load zones defined, you can use the Automatic design toolbar tool (automatic design tool) to automatically lay out the required outlets and the sized unit to use. See the Automatic Design section for complete instructions on using this tool. Or you can choose your own outlet and unit sizes from the Parts catalog.

From the Design -> Parts tab you can add parts to the design from any of the loaded catalogs you are using. The parts are divided into three levels - the part type at the top, the part sub-type in the middle, and the actual sized parts on the bottom level. Only the actual sized parts (from the bottom window) can be added to the canvas.

Simply drag and drop parts from the bottom window of the Parts catalog into the design canvas, and then select and move (or rotate) them into their correct places. If the part you are adding to the canvas can snap-to any other part already in your design, any matching connectors will be shown in green. Compatible connectors on the existing parts will also be shown in green, and incompatible connectors will be shown in red. If a part will snap-to a connection if dropped at that point, its connector will glow in green. User-drawn parts, such as ducting, piping, and wiring can be drawn directly onto the canvas with special draw tools. Draw tools are selected by clicking on their icons in the Parts catalog - you can tell a part has a special draw tool associated with it if its icon has a pencil overlay, as shown:

Once you have created your design, you can analyse the air flows in your existing duct layout with the Solve Air Flows tool (solve air flows tool), or have the program automatically size the ducting for you according to your zone requirements using the Auto-size Ducts tool (automatically size ducts tool). You can also check your design for possible missing connections or inadequate air flows with the Check Design tool (check design tool).

The duct depth of any rectangular rigid duct section can be set by selecting those rectangular sections and using the context menu item Set Duct Depth.

To make a design for a multi-story building, simply use the blue "+" Add level button at the end of the plan level tabs row. This will add a new plan level to your design, and you can add Penetrations between levels to pass duct from one level to another.

These steps are all described in detail in the Design page section.
