Continuity | Types of Continuity : G0, G1, G2 Conitnuity

Continuity :

While creating smooth surfaces, the parameter continuity should be defined. Continuity is to ensure the smoothness of the curves and surfaces. It plays a main role while creating A class smooth surfaces which requires perfect , aerodynamic finishing.



When we create curve points and define continuity, the CAD software displays a set of constraint symbols at each point namely G0, G1, G2 Continuity. Smooth Studio Spline curves and surfaces can be designed in all CAD softwares including CATIA, NX, Solidworks, Autocad, Pro-E etc.

G0 continuity

•  G0 means the two objects are connected, or are position continuous.

G1 continuity

• G1 means they are smoothly connected up to one differentiation, or are tangency continuous.

G2 continuity

• G2 means they are smoothly connected by up to two differentiations, or are curvature continuous.

Points to keep in mind while working with continuity parameter.

•     Any Curve on Surface point can have a G0 constraint to any object that is supported by Snap Point options, and that is within the Modeling Distance Tolerance of the target face.
•     Curve on Surface start or end points can have G1 or G2 constraints to any curve, edge, or surface that is within the Modeling Angle Tolerance of the tangent plane of the point.
•     The software cannot guarantee G2 continuity in all circumstances.We cannot add points beyond a start or end point that has a G1 or G2 constraint.
•     Points on a closed Curve on Surface spline can have only G0 constraints

To Stop Orientation Change in Android OS Smartphones Screen

Automatic Screen Orientation Change :

Nowadays, all the Android Smartphones come with inbuilt motion sensor. If you change the orientation of your smartphone from portrait to landscape position (Vertical to horizontal positions)
the motion sensor will automatically detect the orientation change and rotate the screen to landscape view.

To stop Orientation Change in Android Smartphones :

1. Go to Notification Bar
2. Click Menu Button at the top corner. (In some phones, it is optional)
3. Now a set of quick settings will be displayed.
4. Look for Auto Rotation settings.
5. If it is enabled, disable the settings.
6. Hereafter, the screen orientation will not change until you come back and enable this setting.

Note: Some apps like VLC and some games have special settings which manipulate over this basic settings. So, you have to disable separately for some specific apps, to stop orientation change.

For Android App developers:

1. If you are developing an app , in which you need to constantly fix a particular mode, then you have to include the following syntax in AndroidManifest.xml file.

android:configChanges="keyboardHidden|orientation|screenSize">

To Stop Vibration while typing in Android OS Smartphones

To Stop Vibration while typing in Android OS Smartphones

• By default , the android OS smartphones will vibrate when we touch the keys of keyboard in screen while typing.
• You can stop / turn off the vibration while typing , by two methods.
• First and easiest method is to change the Profile. Vibration will be turned on in Outdoor,Loud Profiles. If you don't want the vibration, temporarily then you can switch to silent or Meeting Profile.

1. To manually turn of the Vibration Go to Settings → Audio Profile → Select the Profile name you want to turn Off the Vibration
2. Now, uncheck (Remove tick mark) the option Vibration on Touch
3. You can re enable the vibration on touch whenever you need.

Advantages of stopping Vibration on touch :

• Battery life will be extended little bit
• Soft feel while typing

Drawbacks:

• Typing same letter twice , because of not sure whether the letter is typed
• Materialistic feel will be missing
