  • Illustrator Bleed
  • by Tom Gillan
  • The term Bleed is used within the printing industry to indicate the "safe" area outside a document to ensure that our artwork will be printed to the edges (or Trim Edge) of the paper, card or vinyl.

  • Illustrator Drop Shadow
  • by Tom Gillan
  • We can add dynamism to our Illustrator artwork by the simple means of adding a drop shadow. The image shown here, for example, was first collaged in Adobe Photoshop from several photographs, then imported into Adobe Illustrator via the File menu and Place. We then used the Image Trace function to redefine the bitmap (pixel) information as vector artwork.
  • Autocad 3D Sweep
  • by Tom Gillan
  • In the case of the Sweep function, we select a 2D closed shape which represents the object's profile and project it along a similarly drawn path. This path may be open like a straight line, curved spline or helix; or it may be a closed path like a circle or closed polyline shape. The Sweep function is also useful for creating objects like threads or tubes on a mechanical fastener.

Such repeat patterns can be used in various contexts, from garment design to representing materials or textures on a floor plan.
  • Photoshop Deep Etching
  • by Tom Gillan
  • Adobe Photoshop provides various selection tools useful to this process. In order to perform many operations in Photoshop we have to select a group of pixels which represent the object.

  • Photoshop Animated GIFs
  • by Tom Gillan
  • Websites can often be enhanced by adding animated elements like animated GIFs. These are very easy to create in Adobe Photoshop. First we create a new file, the dimensions of which will vary according to the web page appearance. In this matter it's best to first check with your web designer about the recommended pixel dimensions of animations. One example could be: 180 x 120 pixels at a resolution of 72 pixels per inch.
  • Autocad 2D Grid
  • by Tom Gillan
  • When drafting in the Autocad 2d interface it can be useful to set up a grid to align and distribute the various elements of the drawing. For example, if you were drawing a floor plan it could be useful to see a grid in order to evenly place structural support beams. Alternatively, in the example of a circuit board diagram, you may wish to draw equally spaced tracks and connectors.
  • Autocad 3D Mesh
  • by Tom Gillan
  • When first starting out with meshes, we first create a new document using one of Autocad's 3d templates - these ship with the program, but can be modified and resaved as your version of the template. Then ensure that you're working in the Autocad 3d workspace - to do this see the bottom right workspace shifter.

By hovering your cursor over these tools, a small tooltip appears which reminds you of the tool's function. The keyboard shortcuts for those tools are also included in brackets.
  • Important Factors in Working with Linear Accelerator Equipment
  • by Leeanne Kunnert
  • Obtaining expensive equipment, such as a linac system, to provide external radiation therapy is a great responsibility for medical facilities. A linear accelerator is crucial in penetrating increased amounts of x-ray energy to conform tumors to destroy cancer cells while maintaining the adjacent healthy tissue.
