An Advance CAD Drafting Technology

The world of drafting changed forever during the 90's when CAD software program became much more exposed on the general population. Before CAD became the drafting industries standard practice Drafters would draw each line by hand on the use of the drafting board, and several hand held tools. This technique was much more time consuming, and for isometric drawings (3D) it could take in days or weeks to try and do hard renderings. More than the last ten years, several software program firms have produced advancements to CAD software program producing the task of drafting much more user friendly on the computer.

If you’re not familiar with CAD or CADD it is the acronym for Computer Aided Drafting. Sometimes it’s named Computer Aided Drafting Design also. Two-dimensional and Three-dimensional drawings are created once the draftsmen enter data into a CAD software program. Lines are drawn on a X, Y, and Z axis to make Three dimensional models. Once designing 2D drawings only the X, and Y axis are used which represent the left, right, up, and down directions. The Z axis is used to make 3D models and represents the depth.

I can remember like a baby my Father teaching me to draw lines, and to write my A, B, C's on a drafting board he created for my room. These boards have a sliding ruler which allowed you to produce lines inside a straight fashion, and they had been covered using a slick material. This allowed rulers, and other tools to slide simply along its surface with out catching to it. The career was much more daunting, and you had to become very careful as soon as drawing lines because even with an eraser mistakes could possibly be observed easily. I enjoyed drafting like this like a kid, but because I've been exposed to CAD I would by no means go back.

It seems like each year advancements in personal computer technology go farther and quicker than the year just before it. When I very first started utilizing CAD software package all of the lines had being put in manually with commands on the keyboard. They would tell the software package to build the lines commencing point, length, and what angle to direction it. This method seemed to consume forever compared to the way lines are made nowadays. From the CAD software package available today it is possible to perform all varieties of commands in a 3D environment. For instance, in case you wanted to add a radius to a corner that has already been created, all you should do is click the command in your fillet. It'll then ask you in your dimension on the radius, and right after you enter the dimension it's going to create a perfectly smooth and rounded corner.

CAD drafting technology becomes a lot more advanced every year with the introduction of updated software. For now, and I believe for a lengthy time to come, AutoCAD drafting software will remain the drafting industries frequent process for making architecture, mechanical, civil, electrical, plumbing, and any other sort design work. The days of using hand tools, and drafting boards is over. These means will never disappear, but for now will remain a lot more of the hobby to most draftsmen.
