This set of irrigation symbols can be used when designing and detailing garden irrigation designs. They are designed for use in the metric environment, where the base drawing unit is mm. The palette includes symbols to indicate the position of the water source, master valve assembly, solenoid valves, typical controllers, and a range of rotator and spray heads.
Each symbol has been drawn on its own layer, L-IRRIG, to facilitate easy insertion using the BLOCKS command. The base point is set in the centre of the symbol.
Tip: Use the block extraction tools on the gCADPlus drop-down menu to extract quantities
As an additional benefit, each irrigation line has been placed on its own layer. For example, a 25mm PVC piping line has been placed on a separate layer L-IRRIG-PVC-25MM. This allows the isolation of that layer and the subsequent extraction of the required piping length.
Tip: Layer naming conventions follow those published by the American Institute of Architects for designers using AutoCAD software.
The figure below shows a typical layout created using this symbol set.
