Aravinthtvt, I agree with WKTaylor. This is a SolidWorks question. I have had experience generating and managing large models. This is well documented under SolidWorks. Keep models as simple as possible. For example, don't use the screw models from McMaster Carr. Model your own...

I am working from home, and I am listening to a classical music station. When somebody calls me, I turn the radio off. As noted above, not everyone has the same tastes. If things are very quiet at the office, I will put headphones on and listen to my radio station. Beyond not inflicting...

renasis, I would not bother with the standard. The clearances and the positional tolerances of your holes are mathematically related. The more accurately you can locate them, the smaller your clearances need to be. Calculating Locational Tolerances -- JHG

Have you looked closely at any "stock cars" lately? If those things are stock cars, then I am Taylor Swift. Are there any stock components in those things anymore? Modern "stock cars" meet regulations that turn them into crash sleds. This has improved safety in stock car racing. I was...

Jack.Smith, As a rule, the fixturable feature of a female thread is the minor diameter. Check your Machinery's Handbook for tolerances on this. Your next option is a threaded pin that screws into your M10[×]1.5 hole. I would assume that this picks up your pitch diameter. Your primary...

Amarks, The last time I designed a drive shaft was very long ago. My shaft diameter wound up being controlled by the two keys needed to transmit torque from a worm gear. -- JHG

SRV = Stevie Ray Vaughn? -- JHG

bddp9, Why can't you just design the arm to snap into open and closed positions? Is manual actuation too much trouble? You get rid of the servo motors. I don't think brushless is any lighter than regular DC[ ]motors. You will need to design plastic snap catches. --...

TugboatEng, One of the reasons for using titanium is that it is chemically very stable. How well do adhesives stick to it? -- JHG

What is the difference between this AI, and the FEA that is attached to 3D[ ]CAD software? This is not quite the same problem, as I have not seen discussions about the ethics of writing analysis software. There is an issue of who is allowed to use the resulting software. I have worked...

Are the AI[ ]people willing to take the responsibility that a professional engineer does? If you are a professional engineer, are you willing to stamp and seal work done by an AI[ ]program? -- JHG

Try to design your fixture. The three datum targets are implemented by spherical topped pins which contact the surfaces at the points (not) specified. On a small surface, I will aim for the middle. Consider that the original question was whether or not a given face could be parallel to...

Mech1595, Is there a dimension to locate datum target[ ]A1? -- JHG

I boasted a couple of years ago that I would write an article on WWII aircraft technology. The project has gotten well out of hand. One of my investigations is alternate history, and one alternate is no WWII. Basically, aircraft technology is driven by the airlines. As you note, airlines...

200918, Did you model this in 3D[ ]CAD? Your spherical radii are equal. I don't think your geometry works. Other than that, your drawing makes sense to me, and I can interpret everything. Your tolerances are super precise. Can you inspect this? Can anybody fabricate it? --...

3DDave, Both connectors in this are panel receptacles. You mount one receptacle, and force the other one into place on the opposite panel. The required force should not exceed five Newtons. Otherwise, you are describing my problem. I have wires, shielding, and shrink wrap tubing, all of...

jassco, No, I have put positional tolerances on the holes of the second receptacle. Everything is constrained. -- JHG

I am preparing drawings of a cable. The figure is something I threw together so that I could ask a question. In the figure above, my datum features are the one receptacle. I am showing profile and positional tolerances for the opposite receptacle, but what I can really calling up is the...

ryanwolff90, Look up flexible features in the standard. When I prepare drawings for flat plates or sheet metal, more often than not, I specify that the primary datum applies when the face is clamped to a flat reference surface. I would also think that restraint either is required, or not...

DVWE, I suspect that they wanted stainless steel and they searched McMaster Carr for it. Thanks everybody. -- JHG
