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. Selection tools are available for adding noise in local. Change to Local and click one of the following tools, and select area you desired.

   

   • Crease - Select faces by growing selections. After you select a face on the part, click and drag the mouse pointer upward to increase the sensitivity of the selection. The selection is dynamically increased. Dragging the mouse pointer downward has the opposite effect, and decreases the sensitivity of the selection.

   • 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 automatically closes when releasing the mouse button 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).
