Drawing units

Ribbon: Home – Properties > Units
Menu: Format – Units…
Command line: UNITS, UN

The command opens the Drawing Units dialog box, where you can define the format and accuracy of the linear and angle units.
By default, the base direction to measure angles is to the right of the initial point (East). Angles should be measured in a counter clockwise direction to give positive numbers.

Linear

Type: Current format of linear units.
Available formats in the drop-down list:

• Architectural
• Decimal
• Engineering
• Fractional
• Scientific
  

Precision: Accuracy of current linear units.

Angle
Type: urrent format of angle units.

• Available formats in the drop-down list:
• Deg/Min/SEC
• Grads
• Decimal degrees
• Radians
• Surveyor’s units
  

Precision: Accuracy of current angle units.

Base Angle: Direction of base angle. Available formats in the drop-down list:

• East
• North
• West
• South
• Pick angle – by specifying two points in the graphic area.
  

Clockwise : To change positive direction to measure angles to clockwise.

Insertion scale
Units to scale inserted content: Units to measure blocks and external references, inserted in a document. If a block or inserted document was created with units which do not coincide with the units set in this section, the block or inserted document will be scaled to the specified units. Scale is defined by the ratio of units in an inserted document and a current document. If the Undefined option is selected, the insertion is performed without scaling.
