Using The Correct Units?

I'm working on a drawing with an annotative scale of 1"=40'. All was well until I started a new session. Inputing a distance intended in "Feet" results in a line length in "Inches". Example: input 70.00 results in a line 70.00 inches long. I have units set to "Decimal" and insertion scale set to "Feet". I have tried placing an apostrophe (70.00') but that is completely rejected. I'm missing something! Any suggestions would be appreciated.

Thank you

It's all inches anyways, if you go by the Dimension style "architectural or Engineering" default measurement multipliers on the primary text measurement.

If you change that to a measurement scale of 12, it'll pretend that you're drawing in feet whenever you dimension something. (ie- 70 units will display as 70'-00" in Engineering units.)

It seems to me like you'd want to set the units to Engineering if you wanted to type 70' to equal 70 feet.. but if you did that, your units would actually be in inches... therefore no multiplier needed in the dimension style

It's safer that way, but you'll need the apostrophe on every measurement you give ( ie- 70'-6" would be input with either: 70'6, 70'6", or 70.5' )

Draw whichever way is more comfortable, and then use the scale command to adjust it if you need to.

I don't know your CAD skill level.. if you need step by step instructions, let us know

Thanks for your reply! Looked back a previous dwg. for settings that I had used. In the Units Box, Type was set to Arch, insert scale set to Inches. In Dim. Style, Unit Format was set to Decimal, Precision set to 0.00. I should have thought of doing that in the first place. Now, entering 70.00' results in a line drawn 70.00 feet long. GREAT!! I'm a retired Civil Engineer, just trying learn what I depended on others to do. Glad to have found CADTutor. Thanks
