Some of reasons to opt for CAD drafting over manual drafting
Manual drafting is difficult than CAD drafting: Before the CAD technology came into the picture the draftsmen used to create the engineering drawings manually with the assistance of pencil and paper. The draftsmen had to struggle a lot while drawing which is not the case with CAD drafting.
Manual drafting is time consuming when compared to CAD drafting: Manual drafting is not so simple. It takes a long time to draft even a simple construction drawing if it’s done manually. On the other hand CAD drafting fastens up the work. It creates the most complex of the structures with ease and comfort in a very short span of time.
It’s easy to make modifications in CAD: It’s not possible even in rarity that a design is created perfect in just one go. That means changes and modifications are obvious in every design created before it goes for the final approval. Modifications in the manual drafting mean changing the whole design and creating it again from the scratch, which is certainly no joke. If not so at least erasing a few lines and creating it again takes your patience. But such is certainly not the case with CAD drawings. Modifying a drawing in CAD is really easy. It just takes a few clicks to make amendments in a drawing.
CAD designs have better accuracy: The design created for construction must be accurate otherwise it can prove disastrous to the entire project. The chances of a design being inaccurate are higher in manual drafting considering the technicalities involved. Whereas CAD drafting gives more accuracy and reliability to a design due to the availability of various design tools in the software which are trusted for being authentic and maintaining accuracy. So giving exact dimension and perfect angle to a drawing is quite easy in CAD.
It’s easy to save and access CAD drawings: Since the drawings are created in computers it is easy to save and access later with the help of internet. Whereas saving manual drawings require a safe place along with immense of papers.
Since CAD drafting has provided architectural engineering and construction industry with so much of leisure AutoCAD remains the most widely used software in this area. CAD drafting is trusted for its reliability, accuracy and speed whereas manual drafting lacks in all these areas. So CAD drafting is best suited to deal with the current demands of construction industry.
