## Wiki Development Help

The Engineering Wiki is powered by the open source MediaWiki wiki package. This is the same software that runs Wikipedia.

To edit the Engineering Wiki, a user login is required. A user account may be created using the links at the top right of the page.

Wiki page development uses a number of special symbols and tags to facilitate text formatting. For help with editing and formatting, refer to the following:

### Wiki Formatting

Consult the User's Guide for information on using the wiki software. Specific Links:

### Math Equation Editing

Math may be used by using $...$ tags in the edit text. The equation text within the tags must use the powerful $\LaTeX$ equation formatting system. Help inputting math formulas using $\LaTeX$ may be found at:

### Figure / Illustration Standards

Figure illustrations may be created in any vector image editing program, such as Adobe Illustrator or Corel Draw. A very capable and free image editor is also available called Inkscape which is available for Windows, Mac and Linux.

Some compiled sample structural analysis figures in vector image format may be found in this zipfile:

These sample image files are provided in five different vector image formats. Whatever vector image editing tool you use should be able to open at least one of these formats (Illustrator, Corel Draw, Inkscape etc.) Note, the objects in the files may be grouped, so to edit them you may have to select the whole image, right click and select "ungroup." You may have to ungroup multiple times.

These images come from the sample wiki page Determinacy, Indeterminacy and Stability, concept questions from lectures, and some quiz questions. When exporting line-art images in bitmap image format to upload to your wiki, it is strongly suggested you use the .png format, NOT .jpg. The .jpg format results in a lot of weird visual artifacts when you use it for line drawings; it is really meant for pictures.
