Changing dimension measurement in drawing

Hi gurus,

I am using autocad mechanical.

Currently, when i measure dimension of my drawings, i have 10 feet(3.048 mm), I want it to change to 10inch(0.254mm) instead?

How can I do that for the whole drawings? Any idea?

Thanks a lot!!!

You want to go from 120" (10') down to 10". Do the math and use the scale command.

Oh i was asking where should i set the scale for the whole page. I found it in dimension style. so my nxt question is.

In the dimension manager, i changed the linear primary units scale factor to 1, alternate units to 25.4

When I get the measurements they are weird. for eg: 1945.29 [49410.47mm]

which supposedly to be 49410.36mm instead. anybody?

I found it! Its the decimal places in the primary. Man, it reflects everything!

If I may suggest something..

The dimension style doesn't affect the item drawn.. if you changed the scale through the dimension style, you are not drawing at full scale anymore. That's what might screw-up your metric conversion in your secondary dimension.

Just because your primary makes you THINK it's 10 inches, rather than 120 inches (10 feet), it's still doing it's math against the actual units measured.

I've always found that messing with the how the primary measurement measures something isn't a good idea. It's a great temporary fix, but might come back and get you down the road.

Though it seems we might have misunderstood your first post.. instead of 10 feet you wanted he same dimension to read 10 inches.. If you had 10 units, and wanted it to read 10 inches, that's a dinesion style change.

But, if you had 120 units (true ten feet in inches), you should use the scale command to fix it.

Glad you worked it out regardless.. just figured it might help someone else down the road.

You should draw everything in model space at FULL size. No scaling UP; no scaling DOWN. You switch to a layout, create a viewport(s) and it is the viewport(s) that a scale is applied to.
