- Select the 4 lines shown below.

- Click EQUAL from the Add Geometric Relation dialog box. This relation makes the length of the two selected lines equal.

* Geometric relations are one of the most powerful features in Solid Works. They’re used in the sketch level to control the behaviors of the sketch entities when they are moved or rotated and to keep the associations between one another. Continue reading…

Drawing Setup IN Creating A Part In Solidworks


Begin the tutorial by opening SolidWorks and selecting “new” from the “file” menu. Notice that “part” designatesa3-Drepresentation of a single design component.


Click on the sketch icon and select a plane of reference as shown in figure1. The box on the left hand side of the drawing has selection options. For the purpose of this part select the front plane. Notice in figure 2 that once the plane has been selected the origin remains visible, and the screen appears blank.


3D Model Objects in AutoCAD 3D Tutorials

 1. Wireframes

A wireframe model is a skeletal description of a 3D object. There are no surfaces in a wireframe model; it consists only of points, lines, and curves that describe the edges of the object. With AutoCAD you can create wireframe models by positioning 2D objects anywhere in 3D space. AutoCAD also provides some 3D wireframe objects, such as 3D polylines (that can only have a CONTINUOUS linetype) and splines. Because each object that makes up a wireframe model must be independently drawn and positioned, this type of modeling can be the most time-consuming.

2. Surfaces

Surface modeling is more sophisticated than wireframe modeling in that it defines not only the edges of a 3D object, but also its surfaces. The AutoCAD surface modeler defines faceted surfaces using a polygonal mesh. Continue reading…

Z Coordinates in AutoCAD 3D Tutorials

I. 3D Coordinates

Entering  3D  Cartesian  coordinates  (X,Y ,Z)  is  similar  to  entering  2D coordinates  (X,Y). In addition  to  specifying X  and  Y  values,  you specify  a  Z value.

1.  Open    a drawing with 3D objects and display in a 3D view.

2.    Type     3DPoly at the command prompt.

Command: 3DPOLY
Specify start point of polyline: 1,1,0
Specify endpoint of line or [Undo]: 1,2,1
Specify endpoint of line or [Undo]: 2,2,1
Specify endpoint of line or [Close/Undo]: 2,1,0
Specify endpoint of line or [Close/Undo]: 1,1,0 Continue reading…

Layers in Photoshop CS6

Photoshop Layers

Layers are a powerful feature of Photoshop that enable you to work on one part of an image without disturbing the rest of it. While the concept of layers may seem intimidating at first, you’ll wonder how you ever survived without them once you get the hang of using layers. Figure 1.7 shows a Photoshop document made up of layers.

Working in Photoshop CS6

Working in Photoshop CS6-6

Now that you’ve been introduced to the Photoshop workspace and have a basic idea of where everything is, let’ s start getting our hands dirty .

Creating New Documents

You can create a new document by selecting File > New… from the menu bar , or pressing the keyboard shortcut Command-N (Ctrl-N on Windows). The New dialog box will appear , as shown in Figure 1.3, where you can specify the document size and other setting.

Working in Photoshop CS6-2Snappy Presets

If you’re designing for a website, be sure to set the resolution at 72 Pixels/Inch to reflect the actual screen resolution. If you’re designing for a minimum screen size, such as 1024×768, be sure to take into account scrollbars and menus, and set your initial document size at a smaller dimension for your actual working area. 1000×650, for example, will give you a better estimate of your actual screen size.

If you want easy access to these dimensions for other new documents, it’ s probably a good idea to click Save Preset… and give the settings a name like “Web Page.” The next time you create a new document, you’ll be able to load your “Web Page” settings from the Preset list.

 Opening Files

Open files by selecting File > Open… from the menu bar, or pressing Command–O (Ctrl–O on Windows). You can select and open multiple files by holding down Command (Ctrl) and clicking on all the files you require in the Open dialog box.

Saving Files

Save a file by selecting File > Save or pressing Command–S (Ctrl–S on Windows). For a newly created document, this will save your work in Photoshop Document (PSD) format. If you’d prefer to save an additional copy of the document, you can use File > Save As… or press Command-Shift-S (Ctrl-Shift-S) instead. T o the great delight of Photoshop users everywhere, Photoshop CS6 introduces a backup save, where a recovery file is saved every ten minutes. You can change the time in between saves by going to Photoshop’ s preferences (Mac: Photoshop > Preferences > File Handling…, PC: Edit > Preferences > File Handling…), and choosing from 5, 10, 15, or 30 minutes, or 1 hour. If Photoshop crashes on you, the recovery file will open automatically the next time you start up Photoshop.

Working in Photoshop CS6-3Double-clicking Power
As if keyboard shortcuts weren’t quick enough, Windows users have even more ways to open and save files, such as:

■ holding down Ctrl and double-clicking the work area to create new documents
■ double-clicking the work area to pull up the Open dialog box to open files
■ holding down Alt and double-clicking the work area to open existing files as new documents
■ holding down Ctrl-Shift and double-clicking the work area to save documents
■ holding down Shift and double-clicking the work area to access Adobe Bridge: Adobe’ s “control center” and file browser

The work area is the dark gray area behind the document windows. If your shortcuts fail, check that you’re clicking on an empty spot on the work area, and not in one of the document windows or Photoshop tools.

Alas, on a Mac, Photoshop only allows for double-clicking the work area to open a document. Even then, you must have Window > Application Frame ticked in order for it to function. Continue reading…
