ISO Standards - 2D CAD Tech. Drawings

Soldering_Iorn

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

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.
