ISO Standards - 2D CAD Tech. Drawings

  • #1

    Hi guys,

    Putting together a portfolio for a job application. I am lacking a 'perfect' 2D technical drawing of mechanical part, by perfect I mean one that abides by all standards e.g. correct line type, tolerances, threads, scaling etc.

    I have found ISO 128 (Parts: 24,34,44,50)

    Are there any other standards that I should be looking at in order to yield the perfect Technical Drawing.

    Thanks :D

    I can't advise on the ISO standards, other than that they tend to be interlinked so you have to get/understand multiple standards to be fully 'compliant'.

    In practice I've never found the complete ISO/ANSI etc. standards that useful, as they tend to be one-size-fits-all. IMHO a "perfect" drawing should communicate the design information as clearly as possible first, then adhere to standards second. Obviously some industries will be heavily regulated and won't allow any deviation from standards.

    I know what you're saying. Have found BS8888 which I will use as a guideline, that and the ISO128/129. Should be fine.
