Converting a drawing in inches to millimeters

[bmwmw73]

I'm doing a drawing for the 2008 Beijing Olympics - it needs to be in inches for our side of the Pacific but the items will be built in China. We are hoping to be able to just do a simple dim style change not a scale manipulation. Any help!?!?!?!?!?

Take a look at the Alternate Units tab under dimensions. Who says you can't have your cake and eat it too...display both at the same time.

Don't forget to set the Multiplier and select your Placement (After or Below)

I don't do this often but scale the entire drawing x 25.4.

The inches'll change to their mm equal; i.e.: 26.00 (inches) will now be 660.40 (mm).

You will then have to change your dim style, larger arrow(s), increase text size.

Piece of cake.

I respectively must diagree with my distinguished colleague Tankman. If the user scales everything up by the aforementioned number it does satisfy the end user (China). However, in the event changes must be made, and there is further work to be done on the drawing, it would be done here in the US. Thus, it necessitates scaling the revised drawing before its sent back to China. What if they fail to do that? Just a thought and not a criticism.

ReMark TANKS for the input.

I don't send my *.dwg file outside the USA. If overseas needs a correction they can mark up the *.pdf file I send 'em. I'll make the revisions to my drawing(s).

Actually, although I've done plenty overseas, don't need any more work then I do in the US of A.

If I did have to make drawings to the scaled drawing, I would do so in mm's anyway. If I had to.

And, off subject, hear 'bout the tunnel being built from CT to LI, NY?
16+ miles, will be the longest tunnel in the world......someday.

I do it both ways depending on the final destination (and who's paying). Each have their own advantages and disadvantages.

Does anyone know definitively WHY USA still persists on using the out of date imperial system of Feet and Inches.. Honestly they should get with the program and change like most of the world has to metric.. Imperial wastes everyones time and money..

Just my 0.02c.....:P

It is probably because they don't need to change, we fit into their system.

They must be good at fractions in their head though.

Damn good. Image multipling 1/64*3/16*7/8*117/128.

In the dim style your doing, modify it and click the alt. units tab, then choose the millimeters option thing.

it's being utilized everywhere in the US and it's ingranied into us at childhood... honeslty, I can visulize 8'-6" but ask me to show you 2 meters and all I can do is guess it's a little over 6' (once again, comparing it to the metric system).

or I can draw a line 3'-8" and then change the units to make it seem like I've drawn everything in metric :lol:

We, the always contrarian citizens of the U.S., should have pressed on with the adoption of the metric system full scale when it was first proposed decades ago. Instead, we have segments of the society who are fully conversant in it while others remain totally, may I even dare say "ignorantly" unaware of it. Our sense of "superiority" borders on the ridiculous.

Side note: The international society of air traffic controllers has made English the defacto standard for pilots and air traffic controllers around the world. The prime reason is to avoid mid-air and ground based collisions brought on by mis-communication.

[Tankman]

I believe the US of A should adopt, embrace, the metric system.

At one time, we in the United States were goin' to adopt the metric system. Have not to date.

Being a world wide community, a standard is required.

As for the original question, why not just change the scale factor of the dim style?

No drawing aspect will be changed and can be updated as needed
as many times as needed

Change the suffix, alt unit preferences, tolorances and anything else you could ever need to show
