Topic: Working in metric (sort of)

[Matt__W]

Can someone enlighten me on this... I need to create some schematic site plans that need to be in metric units.  I've got a site plan (scanned TIF file) that is supposedly scaled at 1:50 meters.  I've got a building footprint that is in architectural units.  I think I've managed to bring in the building footprint at a metric scale.  The big question I have is, how do I create a metric scaled viewport?  I know the ZOOM 1/96XP (for example) trick, but how does that translate into metric?

[mjfarrell]

metric is more like

1:10
1:500
1:1000

[ronjonp]

I'm not alone !

Have been a loooooooooooooooooooong time that I stop doing drafting in metric (metros).... maybe this might help you:

Matt,
Those scale factors from LE are right

They appear to be to be scaling drawn millimetres to metres as well.  e.g. [1:1000]'.zoom 1xp  this is really 1/(1000/1000)......converting it to metres

so if your units are in metres then 1:1000 -> in metres,  is zoom 1/1000xp or zoom 0.001xp

1:100 - zoom 1/100xp , or .01xp
1:200 - zoom 1/200xp , or .005xp
1:500 - zoom 1/500xp, or .002xp

give this a whirl...I dont use vports much myself so fingers crossed

MJ whoever put Centimetres in that table should be shot....There is no such thing, and they should never be spoken about..

[Alan Cullen]

Have to agree Paul...it's either millimetres or metres....I have never seen cms used....and I hate getting drawings from architects in mm too. Cause we have to rescale/move/rotate their work to get their stuff back onto the survey grid. Then every time they send us a revision (every day) we have to repeat the exercise. Aarrrggghhhh.

[jnieman]

It's because 'cm' is apparently used as the standard unit for scientific crap, I think.

It seems that every PRACTICAL application of the units is 'mm' as the base (or meters on things of that scale) ... when I did precision machining and our clients sent us metric drawings, we always read in mm... our tools were mm... no cm anywhere as the units.  I've not done architectural or engineering with metric, but apparently you guys seem to say it's mm too.

So other than measuring a person's height, what IS cm used for? lol...

In the USA, we're taught that 'cm' is the "base unit" for metric linear notation, and not meter for some reason.

[mjfarrell]

you guys be sure to let autodesk in on this will ya?   

[Strucmad]

The whole metric S.I. unit thing is a 10^3 concept..
e.g.
millimetre 10^-3 metres
metre 10^0 metres
kilometre 10^3 metres

Base unit is metre

works for every type of measurement

grams, kilograms, litres, kilolitres, megalitres

even computers are metric lol.

Kilobyte = 10^3 bytes
Megabyte = 10^6 bytes
Gigabyte = 10^9 bytes
Terrabyte = 10^12 bytes

so when you use centimetres its 10^-2 it screws the whole system up....

I think cm are primarily used in medicine, blood flow (cubic centimetres per second) or 5 ccs stat...
bloody medical profession..gods unto themselves..

And Josh we still measure our heights in feet and inches ... go figure 

[jnieman]

YEA, someone told me you used feet and inches, but I was totally unaware... someone said it's only England that uses cm for height or somethign?  I may be way off.

Also, can you tell I'm American, totally oblivious to the rest of the known world?

thanks for the insight... it did seem to me that only scientific (like you said, medical) use cm... weird...

[Alan Cullen]

Yup...height in ft and ins....

Also (being the keen fisherman I am)...fish weight is still in pounds, water depth is still in feet, distance over the water is still in nautical miles, and plane heights are still in feet.

So our current generation know both imperial and metric, although the schools are trying to knock the imperial out of them. But while my generation is still alive, there will always be imperial.

CM are also used for ladies sewing and for cake tin sizes ..   8" pie dish is 203 mm but called 20 CM

a swing and a miss, the "metric" notation here is merely an approximation of the actual binary number   (kilobyte=1028, not 1000)

A question for those in the lands of metric, are not many things measure in centixxxx somethings??  Like engine displacement?

[Alan Cullen]

Possibly, I have heard of cu.cm before, but here in Australia, most engine sizes are in litres. Mine is a 3.6 Lt V6.

   Your on the ball Cadaver... I was waiting for someone to pick me up on that   

Glad to see you back mate....

Yeah bikes are measured in cc 250, 500 1000..

Actually, since we're nitpicking,  a kilobyte is 1,024 bytes not 1028

Our European friends use centimeters for architectural/engineering/etc. work, that's probably why Autodesk included them.

Its used in some scientific calculations in some circles, aka the "cgs" system of units: centimeters/grams/seconds.  I think the "dynes" unit of measurement is based on cm rather than meters, but I could be off on that.  High school was a loooong time ago.

Crud, you're right.  Bit o' trivia though, this being a CAD site and all, anyone care to guess where my brain errantly picked up the 1028??

Not any engineer that I know, nor one that was trained by my family....

The SI units in metric are mm and m; cm are a lazy-man invention which has no place in measurements.
