Any drawing in AutoCAD 2015 will have the drawing units. AutoCAD provides quick and easy way of creating the drawing units. It controls coordinate formats, Angle formats and Precision. The same is discussed in this post. Command Prompt>Key in Units >then Enter using keyboard or Drawing Utilities>Units
Drawing Units in AutoCAD 2015 helps in setting the required units for our drawing according to the profession. For example Architects use inches, where as wood workers choose fraction. Hence it is very much required to choose the correct units according to the profession and also with respect to industry standards. Once the required drawing units are set by the end user , then set up the drawing limits.
Now in this post let us discuss about the Drawing Units in ACAD 2015.
Command Prompt >Drawing Units or Drawing utilities > Units
Here we can specify the UNIT TYPE format for the length and the angle along with precision divisions required after the decimal point.
Architectural Drawing Units– This is the system where in units are displayed in feet and inches.
Syntax: 12’-6”,0’-0” ie. X coordinate =12 feet and 6 inches Y coordinate=0 feet,0 inches
Decimal Drawing Units – Here Metric system of units are followed. One decimal unit can be equal to 1 mm or 1cm or 1m or according to the unit of metric whichever is choosen.
Syntax: 12,0 ie. X coordinate=12 mm and Y coordinate=0 mm
Engineering Drawing Units – It is similar to Architectural Drawing Units but here the inches are expressed in decimal form.
Syntax: 12.5’,0.0’ ie. X coordinate =12 feet and 6 inches Y coordinate=0 feet,0 inches
Fractional Drawing Units - American woodworkers often prefer to set AutoCAD drawings in fractional units of inches because that is how their work is normally reckoned. For example, 12 feet, 6½ inches reads 150-½″ in fractional units.
Scientific Drawing Units – Here in the scientific units, 1.0E02 is broken down into two parts: 1 indicates 1 accurate to a precision of one decimal places and E02 indicates the exponential function raised to the 2nd power, or 10 × 10, bringing the total in this example up to one hundred.
