AutoCAD Units
The units are used to stand for the dimensions in AutoCAD. The units are categorized into length, angle, insertion scale, and lighting.
We can change the units according to the requirements.
We can access the units in AutoCAD using two ways, equally discussed below:
1. First way:
The steps for the beginning method are listed beneath:
- Click on the Application Menu push button, which volition look like the given image:
- Select the Drawing Utilities and and so select Units.
- The dialog box of units will appear on the screen.
two. 2d way:
The steps for the second method are listed below:
- Type Units or UN on the control line or command prompt.
- Press Enter or Spacebar.
- The dialog box of units will appear on the screen.
The Units dialog box volition look like the below image:
Let's discuss the Units dialog box in detail.
Length Type
The drop-downwardly list nether Length type will look like the beneath epitome:
- Architectural Units
The architectural units are based on the feet and inches. Information technology uses fractions to represents the fractional inches. It displays anxiety and inches in the format of decimals and fractions. For case, 4'- 5 ane/two".
Here, single quotes (') signifies feet and double quotes (") signifies inches. - Decimal Units
The decimal units can be represented every bit an inch, meter, millimeter, or whatsoever other unit. - Engineering Units
The engineering units are like architectural units, but they correspond the anxiety and inches in the format of the decimal. For example, four'5.5000". - Fractional Units
The fractional units are the unitless decimal units, which display the value in fractions rather than decimals. For example, 5/ii.
It as well represents whole numbers or whole numbers with fractions. For example, five ½.
- Scientific Units
The scientific units are used to brandish the units in the form of the decimal value raised to a power. It displays the value of exponents. For example, 2.600E + 04. Information technology is used to brandish large values.
Angle Blazon
The angle type consists of the units such as radians, minutes, seconds, etc. We tin select these units co-ordinate to the requirements.
The drop-down list under angle blazon will expect similar the below image:
Let's discuss each type in detail.
- Decimal Degrees
It displays the angle value in decimals. - Deg/Min/Sec
AutoCAD uses d for representing degree because in that location is no keyword for the degree on the keyboard of the figurer. For instance, 10d20'21". Hither, single quotes (') signifies minutes and double quotes (") signifies seconds. - Grad and Radians
The Grads and Radians are the mathematical units.
Since Circumference = 2*pi*r.
So, in a full circumvolve there are ii pi radians.
1 radian = 63.66 grad = 57.three degrees - Surveyor'due south Units
The surveyor'southward units are similar to the grad and radians simply use quadrants instead of a full circle.
Angle Measure out
To measure the angle clockwise, click on the clockwise box to activate it.
The pick is present under the angle. It will await similar the given image:
It measures the bending in the clockwise management, instead of the counter-clockwise direction
Precision
The precision value in AutoCAD determines the number of decimal places displayed in the corresponding unit. The decimals are round off to the specified precision value.
The drib-downwardly list nether precision volition expect like the below image:
We tin can select the precision value according to the requirements.
Insertion Scale
The insertion scale consists of the units to insert in the content. Nosotros can select the units from the driblet-down listing according to the requirements.
The drop-downwardly list under Insertion Scale will look like the beneath image:
Lighting
It specifies the lighting units for the drawing. It enables generic or photometric lights.
When the lighting unit is prepare to American (besides chosen as foot-notes) and international, information technology enables the photometric lighting.
The default or no lighting unit enables the standard (generic) lighting. It sets the value to 0 to maintain the backward compatibility.
We tin likewise type LIGHTINGUNITS in the command line or command prompt to activate it.
The LIGHTINGUNITS value is prepare to 0 to actuate the standard lighting.
The LIGHTINGUNITS value is set to 1 to activate the American lighting.
The LIGHTINGUNITS value is fix to 2 to actuate the International lighting.
The driblet-downwardly list under Lighting will look like the beneath paradigm:
What is photometric lighting?
The photometric lighting uses light energy values, which gives a realistic and natural appearance to a scene. It defines lights more accurately equally information technology would be in the real world.
Direction
The values for the directions are listed in the below tabular array:
| Value | Direction |
|---|---|
| 0 | East |
| xc | North |
| 180 | West |
| 270 | South |
| Other | Used to specify other bending value |
The steps to set the direction are given below:
- Type Units or UN on the control line or command prompt.
- Press Enter or Spacebar.The dialog box of units will appear on the screen.
- Click on the direction option at the bottom, every bit shown in the below image:
- A dialog box volition appear, as shown in the beneath prototype:
- Under the Base Angle, enter 0 for the default bending direction. The default degree is 0 (East), and management is counter-clockwise.
The angle alter is required in drafting.
We can select and specify whatever angle co-ordinate to the requirements.
