And round abouts are clock wise. And airport signs are monolingual.

All these things are true for the moment.... but it's slowly changing, and about time too. There are still these remnants of the old system but look at your food packaging and it's in Kg and grams, milk and petrol in litres. All of UK manufacturing is Metric and almost all of the units we use. Some things cost a lot to convert, but sooner or later it will happen. Kids don't know what inches are and they do all their school work in kilometres. They won't put up with obsolete units forever. Quite why we have these emotional attachments to Pints and Miles is a mystery to me.

We have had this discussion before speaking of clockwise what about time :-60,60,24,7,(28.29.30.31),(365.367) ah a century 100. Regards Paul

Personally I like going for a pint, I don't think going for a 568ml sounds very appealing!

Just got back from having 1.42 litres. No, it doesn't have the same ring to it as 2½ pints John

Aye, and I can't see me keeping to a speed limit of 48.28 KPH either

You will also find that copper tube for refrigeration and aircon is still imperial OD sizes only the length of the coil was changed to metric and that was 35 years ok.

When you buy a pint in the pub you actually get closer to 500ml, the glass needs to be filled to the brim to be a full pint. MPG, ok we drive in miles (why) but but our fuel in litres. Scaling, 2" to the foot etc, its just a ratio of 1 to 6, it could be any units. Anyone mention BSP sizes !!!!!!

What's the deal with nice round figures in imperial units? We happily but 250g packs of butter but don't shudder at the thought of it not being a round imperial amount. It's all nonsense and our friends across the world seem to manage very nicely. You wouldn't need to keep to an off figure of KPH but a rounded one, and the Germans seem to cope with their Lager purchases without going into meltdown. Let's face it, the British just aren't good at embracing change, and that, as much as anything, is why we have so little industry these days. It's time to get in step with the majority of the developed world and put these last vestiges of a dead system to rest.

This is one of the advantages of a CAD package like Alibre, you can set a default to metric or imperial but when you are drawing you can also use the non default units. So its easy to draw the main parts in a metric default but you can also add say a hole in decimal of fractioonal imperial just by adding " after the number. Then when you print the drawing out you choose metric, imperial or both, handy if making a metric part on an imperial mill or lathe as it will give you the amount to turn the handwheels if you don't have a DRO.
I've also added BSP, BA and ME threads and a few specials like spark plug threads to the ones that come as standard which is handy as most of what I still make is imperial.
The other thoing I like is the interactive PDF output which allows you to send a 3D image to someone without a CAD package and they can still manipulate the part and view from any angle, zoom etc.

Hi brought some tyres in Spain recently and guess what they are still using Imperial wheel sizes (stand to be corrected but wonder if the rest of the world is). Worked for the steel industry when "metrification" came in, we used to make sizes like 12.75", 16", 20", 24" but we changed to metric overnight and made sizes 323.8mm, 406.4mm, 508mm, 609.6mm no problem. Wonder how much it would cost to change every vehicle in the world to metric wheels ?, think the pipe industry was driven by our cousins over the pond, not forgetting of course that they passed a metrification law in 1866 ! no rush then. Ducks back down behind the wall, built in Imperial bricks which goes up faster than a metric brick one. Regards Paul

It's simply a matter of being made to do it, which is what the EU is usually good at. Tyre makers won't unilaterally want to change to rounded Metric sizes because of compatibility issues. All the EU needs to do is to say that any new sizes after a certain date must be metric. None of these things are difficult to do.

I can grasp that I need to take another thou off but 0.0254 mm ! it's like learning a foreign language when you still think in english and to be honest I haven't enough years left to worry about it.

I wish you'd stop banging on about UK manufacturing being all metric..it bloody well isn't and I should know! I spent last night making turbine lacing rods and spherical ball joints, and guess what - ALL IMPERIAL DRAWINGS!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Oddly, the Spanish are quite happy with Imperial measure. Odder still is that the supermarkets ,mine anyway, are still quoting pesetas alongside the Euro.
I can still buy Whitworth taps and dies which is easier than here in the UK. My plumbing is Imperial so that the ,one pipe, system can be continued. You know drinking water in and sewage out! Electric wiring is still the wet string variety. The gully gully man still empties the septic tanks but but the garbage is still collected EVERY morning.
On a more serious note, the rest of Europe use half inch sockets as standard. Of course, ALL tyres are Imperial.
Sadly, we poor Brits simply don,t notice the obvious. We go abroad, the sun boils our head, we cease to think, and don,t know where we,ve even been. Then we come home and finally realise it Isn,t cheap in this place that talks funny.
We are all getting excited about the disappearance of the tax disk, when the Spanish have been paying for them on direct debit for years. My recollection is that I,ve been doing this for about 40 years. That was when a new house cost less than a British mini. £450 for a little villa when the cheapest Mini was £497.
I,ll get me sombrero

There are exceptions to every rule, and some industries have been slow to change. However, the fact is that for an international market, manufacturing has largely had to switch to Metric. Even the USA is producing mostly Metricated products for the same reason. A universal common measuring system is essential for world trade, and like it or not, that's the market, not a home one.

All the EU needs to do is to say that any new sizes after a certain date must be metric. None of these things are difficult to do. The global oil and gas industry is still imperial - valves, bolting, joints, much of the flow measurement, rotating equipment specs etc. Changing to metric manufacture only in Europe would be a step backwards as the world market would be lost. Even in Brazil I place hundreds of thousands of pounds worth of orders for imperial stuff every year. With offshore units being built increasingly for a 25 year Field Life the imperial spares will be needed for a long time to come. During that time more installations will be built using imperial kit and so it goes on. Imperial stuff won't go away any time soon. Reg

Thought I'd have a play with Cubify Design tonight, so I knocked up my interpretation of a set of 15xx captive buffers and stocks, though the retainer and spring aren't yet drawn. I'm impressed, think it's likely to be the one I'll buy, can't really argue with 129 quid considering the prices of the other packages around. Cheers, Rob Looking good there Rob. I am thinking of changing my old version of TurboCad to a parametric 3D modelling package, can Cubify Design do a cross-section drawing? If you get a chance can you put an example of 2D drawings generated from your model and let us know how easy it was to achieve please. Baldric

I had a look on the website and it says cubify can only export STL files, does this mean it can't save files as anything else? I'm thinking of drawings for laser cutting which need DXF. Otherwise I too am impressed!! Like Baldric said, I'd like to see more but at first glance this seems the way to go bearing in mind I'm only going this as a hobby not a full on business!
Cheers Ben
