    Ignore a new clause in the recent code

    You're either designing to code or not. Anything that isn't 100% to code, including every clause, is not "designed to code." -- SirPhobos

    List of acceptable THRU callouts

    If anything, I'd denote it as "THRU TO CENTERLINE" in your example (and make sure the print shows clearly which walls that would include). But I've typically seen something more like "THRU NEAR SIDE ONLY" or "THRU ONE WALL". -- SirPhobos

    Reverse Deflection in Cantilevered Balconies?

    I'm certainly out of my element here, but I'd think that if you saw enough "lift" on the balcony, you'd see a similar or more severe depression on the inside of the balcony. Surely it would be noticeable if the room inside the balcony had a depression between the exterior wall and next interior...

    Laser Etching - Automotive Painted Plastic Parts

    Talk to whomever would be doing the etching. In the past, I worked with a subcontractor that would take a provided .dwg file and use it directly with their machine to do the engraving. Then, as long as I had what I wanted on the drawing, it would show up how I expected. There was no need to...

    Planes or views on custom coordinate plane

    In the part model, orientate the part how you want it to appear in the drawing view. If you want to be looking normal to a face, select the face and click "normal to". Then hit space and save the view. Then, when you insert a drawing view you can select that custom view model orientation. Am I...

    Shear Pin Stress Calculation

    The beam theory calculation is derived based on equations for bending. It is a result of both vertical shear and a bending moment causing internal shear along the length of the member. Thus, if we were to isolate a single point of material, the total shear force would be a vector at an angle...

    Methods to reduce assembly gap

    I think the most basic answer would be to tighten up your tolerances. If the container length is 3 -0/+.1, and each block is 1 -.1/+0, then the largest gap is 0.4. If you tighten all those up by half, the container becomes 3 -0/+.05 and each block being 1 -.05/+0. This results in a maximum gap...

    Adding assembly of components on detail prints.

    Anything that needs to be handled/ordered separately seems like it would need it's own identifying number. The machining could be called-out and dimensions provided by the assembly drawing (as opposed to a separate drawing for the part without plug). But you'd still need to call for the material...

    The Pitch of an Intermittent Weld

    In the end, the goal is to communicate what you want/need. The purpose of standards is to help clarify. If you are asking if it's acceptable according to a specific standard, I have no idea. But if you're not strictly following a standard that specifies how such things need to be communicated...

    Diagonal holes in framing members?

    I'm out of my element here (I do industrial machine design - not structural or with wood), but if you want an opinion, I'd say go with assuming it's a 5" hole. Taking the question and assuming that it is valid to assume the length to be considered is only the length on one face (2.5" in your...

    Hello Engineers I want to know, Wh

    Generally, I'd say the terms are interchangeable. In my mind, when I think of a bushing it is a device used to protect or modify a housing, such as a hardened drill bushing or a threaded insert. When I think of a sleeve, it is device used to lubricate or reduce friction between parts. However...

    Weld Callout for Square Tubing with Mitered Ends

    Thank you for the input and replies! The frame is not supporting since any sort she significant weight or subject to forces that I am concerned for the strength of the weld. The frame is being used in a wash down environment, which is what necessitates the welds to be continuous and...

    Weld Callout for Square Tubing with Mitered Ends

    This might be a very simple question, but I haven't had much success in finding an answer elsewhere. We are taking square tubing (say 2" x 2" x 1/8" thick wall) and mitering the ends at 45 degrees to make a the tubes create a 90 degree corner. These get welded together to make a frame. The...
