Drawing in METRIC

[dmee]

I’ve been using CAD for about 8 years and I have never fully understood the proper way (if there is one) to draw in metric. I’ve been told 2 ways:
1. change your units to decimal.
2. have your units in imperial and put a conversion in your dimension style
I don’t want to draw in imperial because it’s a hassle to keep converting things when I’m checking sizes.
My problem is…..I’ve been drawing in decimal (because I wanted it in metric) but when I go to scale the drawing in paper space it’s not to scale. I know how to scale drawings, the paper size is correct, the viewport is correct, everything is fine.
For example… I have a drawing in decimal units, I scaled it in the view port at 1:1500 on a 24x36 size paper. When I print it it’s not to scale.
How am I suppose to draw in metric when there’s no unit for it. I know the decimal unit isn’t metric but I don’t know what else to use.

The problem is you're mixing metric/imperial units between modelspace and paperspace, since you have an imperial paper size. You either need to use metric paper (mm) or factor in a conversion. You want it to plot at 1:1500. Think 1 plotted inch=1500 MS inches. But MS is in mm, so 1500 inches = 1500 x 25.4 = 38,100 mm. So to scale a viewport, do a zoom 1/38100 xp. (I hoped I worked that out correctly)

Thanks that helped.
I changed the scale in the "page setup" option to 1"=25.4units and everything came out to scale.
