Creating The Retaining Tabs in Soilidworks

Retaining  Tabs

Tabs are required to hold the component firm during the milling process. These tabs must be durable enough to support the weight of the part, as well as, resist the cutting forces applied by the milling machine. However, once the milling process is finished these tabs must be removed without damaging the part or obstructing its function. Begin by selecting the top view from the upper toolbar. The various viewing options are shown as cubes with highlighted faces to depict each surface. Next, click on the face of circular region shown in the top view. Figure 12 details the colored shading that occurs when the surface is selected.

Creating The Part in Soilidworks

The completed part will be circular. However, the sketch is that of (½) of the transverse section of the entire component. Accordingly, select the line function to draw this section.

Create The Profile

Begin at the origin and (WITHOUT DRAWING A LINE) move along the horizontal axis a small undefined distance as shown. Next draw a backward “7” or upside down “L” as shown in figure 6.

Choosing A Color Mode in CorelDRAW Graphics Suite X6

Choosing a color mode

When you create a new CorelDRAW document or Corel PHOTO-PAINT image, you must choose a color mode, preferably based on the color model that corresponds to the project’s destination. The color mode determines the colors to be used in the application. For example, if you know that the intended destination for your project is the Web, you can choose the RGB color mode. By choosing the correct color mode when you start a project, you can take some of the guesswork out of choosing colors. As a result, the colors in your projects will be reproduced more accurately.

The CMYK color mode is recommended  for printed material, while the RGB color  mode  is recommended for material that will be viewed online.

How Are Colors Defined? in CorelDRAW Graphics Suite X6

Color is literally in the eye of the beholder. The sensation of color is a result of the human eye’s response to light and the nervous system’s interpretation of that response.

Color Basics in CorelDRAW Graphics Suite X6

Color perception depends on the eye’s response to light.

Through the use of color models, this complex process has been defined mathematically. The color models allow software applications (such as CorelDRAW and Corel PHOTO-PAINT) and digital devices (such as computers, monitors, digital cameras, and printers) to store, manipulate, and accurately reproduce color.
