Snap-to lets you join parts together that have matching connectors. To match, the connector must have the same size and shape as the connector on the part you wish to join it to. Connectors can be either circular or rectangular. If a connector can match the part or tool you are using, it is shown in green, or if not, in red. A connector will glow green to show that it has locked onto a matching connector or tool, and will snap-to if you complete your action at that point.

Parts and their connectors

A connector may come in multiple sizes. If a specific size matches the tool or part you are using, the connector will be shown in the matching size.

Breaking Connections

If you are repositioning a part that has other parts connected to it with snap-to, then those parts will automatically stay fixed to the part you are moving. If you want to break those connections, either drag the part or parts while holding down the Control [Ctrl] key, or use the context menu item Break Connections.

Finding Compatible Parts

You can use the canvas context menu item Connect New Part to see and select only those parts in your active catalogs that can make a connection with the part you have selected. Choosing a part will add it directly to the selected part in the canvas. This saves the effort of searching through your catalogs to find a correctly sized matching part. If the selected part has multiple connectors, the closest connector to where you have clicked on the part is used. This is shown by drawing the selected connector in blue.

Neck Adaptors

Diffusers and grilles are often supplied by the manufacturer as a kit including the appropriate neck adaptor. Such a part can connect directly to round flexible ducting, and will be shown with a round connector (for example, the round diffuser shown bottom left in the above image). Other diffusers and grilles require a neck adaptor to be fitted before they can connect to flexible ducting, and these will be shown with a rectangular connector which fits a rectangular neck adaptor (as in the square diffuser shown bottom right in the above image). You need to connect the appropriate adaptor before you can connect such a diffuser to your duct work.

Special Fittings

In some unusual cases, components may have connectors that are special fittings, and can connect only to other similar special fittings. In these cases, an ordinary connector of the same size and shape will not connect to it, only another correctly sized special fitting.
