Add Noise

Add noise to the surface of a part to create ergonomic feature such as grip for knobs.

Note: Click Simple UI to switch between the simple and the advanced User Interface. In the Simple UI, only the tools for minimum workflow are visible.

1. In the Prepare tab, click Add Noise.

2. Select Global or Local.
   

3. Depending on your selection, follow the appropriate steps below:

   • Global

     Select a part.

   • Local

     Use the Selection tools to add noise locally. Choose one of the following tools and select the desired area:

     

     • Crease - Select faces by growing selections. Click a face on the part, then drag the mouse pointer upward to increase selection sensitivity or downward to decrease it.

     • Brush - Select faces by drawing on the part.

     • Rect - Draw a rectangle to select faces. Faces inside the rectangle are selected.

     • Lasso - Draw a closed loop on the part. The loop closes automatically when the mouse button is released, and faces inside the loop are selected.

4. Select options.

5. Click Apply to add noise on the surface of the part.

   Note: The Undo and the Redo are available until you exist the command by clicking Close (X).

Modulate - Click to select the preset noise type and modulate its density.

Zero (Min. 0 - Max. 255) - Sets the zero point of color intensity to add noise by replacing the defined colors.

Tolerance (Min. 0 - Max. 255) -

Type - The following noise types are available. Select one of noise types.

Basic Noise	Smoothed Noise

Density (Min. 0 - Max. 8) - Adjust the slider to control the density of noise in a unit range.

Granularity (Min. 0.05mm - Max. 10mm) - The density of the noise content in a unit range. The smaller granularity, the more dense and rough granules are created in a unit range.

Note: Select the Use Current option to use the density of triangles in the selection or in a mesh as the granularity level of noise.

Range (Min. 0mm - Max. 5mm) - The minimum unit range of granules. The smaller range, the more dense and small granules are created in a unit range.

Granularity : 0.5mm Range: 0.5mm	Granularity : 0.2mm Range: 0.5mm	Granularity : 0.05mm Range: 0.5mm
Granularity : 0.5mm Range: 0.2mm	Granularity : 0.2mm Range: 0.2mm	Granularity : 0.05mm Range: 0.2mm
Granularity : 0.5mm Range: 0.05mm	Granularity : 0.2mm Range: 0.05mm	Granularity : 0.05mm Range: 0.05mm

Smooth (Min. 0 - Max. 8) - Adjust the slider to control the smoothness level of noise in a unit range.
