How to Draw Mechanical Engineering Drawing

Even attempting to do a basic 2D drawing of an engineering component in PS would be a major undertaking and from a professional standpoint pretty much a waste of time. You can't do anything with such a drawing than use it for yourself. Outside the complication of actually generating the lines and stuff, the real point would be that even in the remotest parts of the world there are rules and standards you have to adhere to and those can't be communicated properly with what essentially would be a scribble on a napkin when you do stuff in PS. Proper tech drawings carry tons of extra info, metadata and ultimately even the layout of th drawings themselves is standardized. You're really looking at the wrong tool when attempting this in PS. As already suggested by the others, you have to look into serious CAD-related tools or at least have Illustrator decked out with additional plug-ins to even come close to producing usable tech drawings.

I guess you can make engineering drawings with Photoshop, it would put you at a huge disadvantage.  CAD programs are designed specifically for purpose, and are not so much 'faster than Photoshop' for producing engineering drawings, they are orders of magnitude faster than Photoshop.

I have spent many thousands of hours using Autocad as a design engineer, and have used Photoshop almost since its outset.  I am retired now and wouldn't want to pay the high prices for Autocad, but I enjoy using Sketchup much more than I ever did using Autocad.  It's easy to use and there is a free version and there are a ton of tutorials available.

At its core, Adobe Photoshop is an image editing application. While Adobe Illustrator is a drawing package and can do isometric drawing, most mechanical engineering drawing is done in non-Adobe applications such as SolidWorks, AutoCAD, Autodesk, and others.
