    Stupid question

    We all know that, and proud of this knowledge, but is there place in Y14.5 where placing datum feature symbol on axis is explicitly forbidden? Just in case I need to point someone's nose into it? Thank you. "For every expert there is an equal and opposite expert" Arthur C. Clarke Profiles of...

    Y14.5.1 - 2019

    Has anyone got a chance to look at the copy of Y14.5.1 - 2019? Is it worth having? "For every expert there is an equal and opposite expert" Arthur C. Clarke Profiles of the future

    Incomplete Threads

    Is there a way in SolidWorks to: a) Specify a length of incomplete thread? b) Control a length of incomplete thread thru Hole Wizard or by other means? Thank you in advance. Any ideas will be greatly appreciated. "For every expert there is an equal and opposite expert" Arthur C. Clarke...

    Measuring complex area

    Does anyone know the way to measure combined area of multiple faces? I can get surface area of the entire part from "mass properties" command. I can get surface area of a single face using "measure" command. But I cannot find command/setting to measure total area of multiple faces picked...

    General case of angularity

    In recent discussion thread1103-442213 we opened Costco-sized can of worms regarding use of orientation controls. Here is the question I wanted to ask but had a feeling that it would hijack the thread, add confusion to the discussion and not get as much attention as (in my opinion) it deserves...

    Can indirect control override direct one?

    There was very heated exchange recently on this forum caused by ambiguous understanding of some standard terminology. Unfortunately, most participants concentrated on emotional part of the discussion, and overlooked serious underlying problems. Here I have no intention to start another fight...

    Projection Symbol

    This is the first time I encountered projection symbol combined with letter "E". Any idea what it represents? Envelope? European? "For every expert there is an equal and opposite expert" Arthur C. Clarke Profiles of the future...

    Is anyone familiar with Clamp Bolt standard?

    Gentlemen, I hope this is the right forum to ask question about fastener. On the enclosed picture I circled Clamp bolt. Does anybody know International/national/local/factory standard (or at least some sort of "cheat sheet")that regulates such fastener. The idea is not to re-invent the bicycle...

    Spherical Tolerance Zone

    I recently run into question that I thought could be interesting for the rest of this forum: what spherical tolerance zone is good for? ASME Y14.5-2009 Fig. 7-35 shows obvious application for locating spherical feature of size. Now, if I want to locate point in space, there is nothing wrong...

    The Invocation Principle - Good or Bad?

    For all the ISO - lovers out there I introduce new beating horse - The Invocation Principle. According to 2011 edition of ISO 8015 which is now regarded as "fundamental GPS standard", "Once a portion of the ISO GPS system is invoked in a mechanical engineering product documentation, the entire...

    Colors on the "blue" prints

    I have an unusual question (as most of the people on the forum). As someone who grew up in the times of pencils, paper and poor quality blueprints I am a firm believer into strictly black-and-white linework. Nevertheless in today’s world you can hardly find B&W printer or copier if you want to...

    Axis of a square shaft

    I have a simple question which unfortutely doesn't have simple answer (or I couldn't find it). Imagine a shaft having two sections - round and square To simulate working conditions of the shaft I have to put square end into collet, rotate it and measure Run-out of the round end - something...
