Advantages
* Can be more accurate than hand-drawn designs – it reduces human mistake. * You can salvage and redact thoughts. which makes it easier and cheaper to modify your design as you go along. * You can modify bing thoughts. which saves clip.
Disadvantages
* The package itself can be expensive so initial costs are high. There are free package bundles though. * Staff demand to be trained how to utilize the package. which besides adds to costs. * Requires a Personal computer.
A few advantages of 2D Cads:
Reduced design timescales.
Reuse of designs.
Pulling mistakes can be corrected easy.
Drawings can be sent/received via electronic mail in seconds.
Disadvantages:
Time & A ; cost of implementing the CAD system
Time & A ; cost of developing people to utilize the CAD.
Time & A ; cost of migrating bequest drawings into CAD format
If you compare the usage of 3D CAD against pulling borard draughting. the list of disadvantages reasonably much stays the same. whilst the list of advantages grows further.
Advantages of 3D Cads:
More fashionable /complex merchandises can be designed utilizing 3D surfacing. Parametric patterning allows many design itterations to be generated & amp ; evaluated rapidly. Designs can be analysed and optimised virtually utilizing finite component analysis. Clearance/inteference cheques can be mase easy
3D CAD informations can be imported straight in to CAM package. futher cut downing timescales and errors from reading of 2D drawings.
Advantage:
Software Flexibility
* Using CAD package enables design alterations to be made quickly. Before CAD. a peculiar design alteration would hold required a draftsman to wholly redraw the design to the new specification. CAD package allows interior decorators to putter with designs and do little alterations on the fly. It can besides be used to imitate the behaviour of the design in package. For illustration. CAD package can be used to imitate the air flow around an engine. This allows for greater flexibleness in the package design procedure.
Advantage: Automatic Specification Checking
* Using CAD package enables the interior decorator to automatically look into if the design is within specification. CAD package besides enables clients to see designs at an earlier phase in the design procedure than is normally the instance. CAM besides enables clients to look into the advancement of functional and semi-functional paradigms at a much earlier phase than is possible in the traditional design procedure.
Disadvantage: Processing Power Limitations and Cost
* CAD package frequently consumes big sums of computing machine treating power. This requires high-quality computing machine hardware that can be dearly-won. CAM requires advanced fabrication devices that are besides really expensive. The cost of hardware is a important disadvantage of CAD. CAM and a major barrier to the wider consumption of CAD. CAM engineerings
. Disadvantage: Software Complexity
* As CAD package progresss. it becomes more flexible and adaptable. However. this comes at the cost of doing the package more complex. This complexness makes it more hard for first-time users to larn the package. Combined with the cost of developing forces in CAD. CAM technologies. this complexness represents another disadvantage of CAD. CAM.
REVIT:
Many advantages and disadvantages. It takes more clip to put up a undertaking. and to put up all the constituents you want to put in a edifice. Revit is much better at 3 dimensional mold. It besides does some basic design material.
Ms office:
Advantages:
• Widely used. and accepted in concern universe. so compatibiity
• Supported by major corporation. so small opportunity of it going disused
• Wide assortment of characteristics. leting you to make most anything
Disadvantages
• Made by Microsoft. ??
• Too many characteristics. creates an highly high acquisition curve
• Very expensive.
The advantages are that you need merely come in a expression for the spreadsheet to continually update sums whenever information is entered instead than holding to continually re calculate.
The disadvantage. if there is any. is that other than simple computations you do necessitate a good trade of preparation to acquire the best out of it.
