Cad Drawings Vs Hand Drawings

Cad drawings vs hand drawingsCAD ( Computer Aided Design ) is a piece of software used to make much more efficient 2 dimensional or 3 dimensional (2D or 3D) drawings rather than having to draw it out on paper with pencil. Companies such as building groups can buy CAD to use it to produce better and more accurate drawings for them to use.

It makes it faster to produce drawings as you don’t need to measure the line you’re drawing as you can enter it onto CAD and it automatically draws the line. Also you only need to move the mouse and click on separate options to edit the drawing as you don’t need to spend time erasing certain lines. This increases the selling rate as people can draw projects in much less time to be able have the project finished quicker.

CAD makes drawings more accurate to produce as you don’t need to be spending time setting a ruler up as you can just program a setting to make all lines 90o or 45o etc. This saves hours of work in total as setting up the ruler might take a minute. Over time this will result in a loss of time, by using CAD setting up lines only takes a click or two of the mouse. From then, over time you will save important time where you can work on something else. You can also draw ‘isometric’ drawings on CAD accurately, you can set the line angle to isometric so that every line is in isometric view, this would be degrees going up in 30’s. With technology now you can take the isometric drawing you have on CAD and put it on a software so that you can see what the product looks like in 3d form from different angles. Companies would find this very helpful as they can then have a rough idea of what to make the 3D model from.

If you were asked to draw copies of a drawing you have spent some time on, it would be a pain redrawing it, but on CAD you can easily repeat drawings. If you wanted something copied you just highlight it then copy, this can
