Mechanical drawings are an excellent way to convey design information, and while sophisticated 3D modeling is slowly taking over, with some companies accepting files over drawings, the mechanical drawing remains the written contract so to speak for complex parts with tolerances and non-modeled features.
But if you didn’t take a technical drawing class (typically Engineering Drawings 101), how do you learn? Well, if you have 15 minutes, this is an excellent video, which speaking from experience, covers the basics from the 101 course.
The lesson covers all the basics, from 2D projection, multi-view drawings, isometric projection, cross sectioning, linear dimensioning, basic tolerancing and alternate views.
Narrated and taught by [Chris Guichet], the reviews are in:
“Top notch video. Clear and informative, lots of good information here. (Source: 20+ year draftsman)”
– Roger Haley, YouTube
“Just skimmed through the three sections. I’m really impressed, you probably covered 50% of a GD&T course in 15 minutes.” – Yamugushi, Reddit
And speaking personally as a mechanical engineer, I’d have to agree.
