Nature Drawings - How to Draw

The vector clipart library Watercraft contains 28 images of vehicles: ships, yachts, boats, vessels.
Use the vector stencils library Watercraft to draw water transportation, ships and vessels illustrations, presentation slides, infographics and diagrams using the ConceptDraw PRO diagramming and vector drawing software.
"The term watercraft covers a range of different vehicles including ships, boats, hovercraft and submarines... Usually the purposes behind watercraft designs and skills are for seafaring education or leisure activities, fishing and resource extraction, transportation of cargo or passengers, and for conducting combat or salvage operations. In general, the purpose of a water vehicle identifies its utility with a maritime industry sub-sector." [Watercraft. Wikipedia]
The design elements library Watercraft is included in the Aerospace and Transport solution from the Illustration area of ConceptDraw Solution Park.

The vector stencils library "HVAC controls" contains 23 symbols of HVAC controls (sensors, actuators, timers, controllers, I/ O points).
"HVAC (... Heating, Ventilation and Air Conditioning) is a control system that applies regulation to a heating and/ or air conditioning system. ...
Central controllers and most terminal unit controllers are programmable, meaning the direct digital control program code may be customized for the intended use. The program features include time schedules, setpoints, controllers, logic, timers, trend logs, and alarms. The unit controllers typically have analog and digital inputs that allow measurement of the variable (temperature, humidity, or pressure) and analog and digital outputs for control of the transport medium (hot/ cold water and/ or steam). Digital inputs are typically (dry) contacts from a control device, and analog inputs are typically a voltage or current measurement from a variable (temperature, humidity, velocity, or pressure) sensing device. Digital outputs are typically relay contacts used to start and stop equipment, and analog outputs are typically voltage or current signals to control the movement of the medium (air/ water/ steam) control devices such as valves, dampers, and motors."

Use the design elements library "HVAC controls" for drawing the HVAC system diagrams, controls drawings, and automated building control and environmental control system layuout floor plans using the ConceptDraw PRO diagramming and vector drawing software.
The shapes library "HVAC controls" is included in the HVAC Plans solution from the Building Plans area of ConceptDraw Solution Park.
