In my bit of Lancashire our secondary schools are usually officially called xxx high school and everyone says high school rather than secondary.

That sounds about right for street homeless for a European nation. The UK figure in reality is probably about that as the way street homelessness is measured in the UK is set up to undercount.

This is a good breakdown of how incompatible homelessness statistics are. Really that Wikipedia table is hugely misleading https://www.google.com/url?sa=t&source=web&rct=j&url=https:/...

How homelessness is measured varies massively between countries. So Britain has an estimated 4751 people sleeping rough, but 307,000 people who are homeless, i.e. living in temporary accomodation, sofa surfing etc. The USA has an estimated 190,000 people sleeping rough (in cars, tents, on the streets) but only counts a total of 540,000 people as homeless. I don't know how the American figures are counted but the German ones are probably estimated in a similar way to the British ones because we live standardised statistics in the EU.

In blender at least you can specify the size of any primitive, measure the length of any edge, measure between any two points, move a vertice, object, or face by a specified amount etc. so this is just not true for blender at least. You can also annotate any dimension easily with a dynamically updating annotation. What you can't do easily (unless you're prepared to do some serious python scripting) is parametric / constraints based modelling because it's not a parametric modelling program. I'm not sure what else you'd want.

As to why visualisation folk don't care about dimensional accuracy, we do when necessary, but unless we're designing for 3d printing there's no point in worrying about things like clearances and tolerances since we're not making a physical object. Also, especially if we're doing arcvis, the demand is to knock out large quantities of models very quickly, not produce a perfect replica. I'm not going to worry about the exact dimensions of a piece of complex equipment or furniture I'm modelling if I need to produce a fully textured model in under an hour.
