Introduction The concept of computer aided designing for landscape gardening is comparatively new. It can be simply defined as design and drafting of a landscape garden with the aid of computer. A CAD system consists of IT hardware (H/W), specialised software (S/W) and peripherals, which in certain applications are quite specialised . Computer aided designing is an important industrial art extensively used in industry and 2D or 3D landscape architecture designing.
History In 1960, This technique was initiated by Massachusetts Institute of Technology, Ivan Sutherland and created SKETCHPAD, which demonstrated the basic principles and feasibility of computer technical drawing. The first system were very expensive, the computer graphics technology was not so advanced at that time and using the system required specilised H/W and S/W which was provided mainly by the CAD vendors. In 1980, AUTODESK was the first vendor to offer a PC based CAD system, the AUTOCAD. The first application of CAD were for only 2D modeling.
Need of Computer aided design in landscape The technique was aiming at automating a number of tasks a designer is performing and in particular the modelling and designing of gardens and infrastructure. CAD systems can shorten the design significantly. Traditional drafting is repetitious and can be inaccurate, while, CAD provide accurate and efficient drafting with repetitive option which is prime need for a landscaper . In order to complete the design in less time and with the least mistakes.
Components of CAD system
Major steps in designing landscape gardening through CAD system Selection of site and it’s analysis. Determining needs.( Hedge, shrub ,trees etc.) Creating functional diagrams. Developing design plan. Drawing of final design.( In 2D or 3D model) The first three steps establish the aesthetic, functional, and horticultural requirements for the design. The last two steps then apply the requirements for the creation of the final landscape plan.
Functions and limitation of CAD software AutoCAD software Function : 2D or 3D view of the design. Cross-platform . Import 3D models . 3D Navigation providing functionalities to view the environment in different angles and by adding multiple camera. Export 2D or 3D plan. Proper documentation and Community support . Limitation : High cost. No cost estimation.
2. Floor planner software Function : Provides a 2D view to design. The design can be viewed in 3D. Freedom to navigate around the 3D environment. Library of 2D textures and 3D models. Can draw for scaling. Running on the web browser. User-friendly
Limitation : Cannot import symbols or 2D textures. Cannot modify the 3D terrain/floor. Lack of cost estimation feature.
3. Garden Planner Function : Over 800 pre-designed elements. User-friendly and environment transformation. Drag & drop elements. Elements scaling. Each element can be exported to an image. List of elements used with its dimensions . Limitation : No situation awareness mechanism. No 3D elements library. Lack of 3D environment.
Advantages of CAD system Drawing errors can be corrected easily. Drawings can be sent and received elsewhere quickly via e-tools. Drawing can be zoomed, copied and pasted for more detailed sections. Reuse of designs. Can be stored in personal computer. Reducing timescales and mistakes. It provides a 3D sketch of the layout before its final implementation. It provides rotation of images to view them from different perspectives. Switch between 2D and 3D view is possible. It is cost effective than manual drafting on paper.
Disadvantages of CAD system It can be very expensive. It can be hard to do and handling needs training. Sometimes can’t do everything you want to because the tools are not available. Sharing of drawings via computer hacking.
Conclusion CAD software makes use of some of the best tools, the percentage of error is significantly reduced . Computer aided design software saves time and more efficient designs can be made in shorter time duration. The CAD tools make it easier to save the files and store it in a way that one can use it time and again and send it without any unwanted hassles too.
