  • Yeah, I know some of that exists; it never showed up in my world. We never modeled buildings with enough detail to make it really useful. Occasionally someone would get excited about Tekla and we’d spend some time trying to do shop drawing reviews in 3D and then go back to PDF. What I meant was that it isn’t yet a standard thing that is understood by any technician in the industry, it’s proprietary software that is subject to change with every release.



  • Prints have a design language to them which allows you to express fully constrained geometric designs on a napkin if you need to. Dimensions, radii, diameters, angles, datums, positions, projections, sections, GD&T. None of this is obvious in a 3D model. You don’t know what the driving dimensions are, what can be inferred from other dimensions, if it is a coincidence or a requirement that two features line up, etc.

    This is so critical. In architecture and structural engineering, you can add to this that you don’t actually know a lot of the real dimensions - you’re laying out the important ones from the structural grid or from survey points, and whatever is left doesn’t matter.

    Even markup, at least in a design environment, can be done in 3D (or at least on a computer), but the communication of constraints, that is, what dimensions are important and which are irrelevant or unknowable has not yet been developed in 3D models, and I suspect it will be some time before any useful language for that purpose stabilizes.


  • I am a pale bald man and thus require protection from the elements. I also have always loved hats, and I was definitely a fedora kid.

    Personally, I prefer smaller hats and caps for the city, especially if I’m riding a bike. I wear cycling caps, bucket hats, factory caps, berets, etc.

    I like proper hats, but have found that both the fedora or teardrop crown and the cattleman crown have too much stigma. Instead I generally wear a telescope crown, that is similar to a pork pie. I currently only have one such hat, a really big palm leaf straw, and it feels pretty audacious to wear in the city. I used to have a smaller one, with only a 2” brim, and that felt quite at home. I also used to have some felt hats in the same shape, but they needed too much care and are expensive to replace, so I have not.
