======Overview Expert Mode======

In expert mode, **all** input parameters/options are displayed in separate input windows.

{{en:media::overview-expert.png?100%&link}}

==== Expert Mode ====
Each input window provides and/or displays all **detailed value entries, ** such as all 
powder-specific coefficients and constants. In addition, the cartridge drawing of the
original **(CIP-) caliber specification** including all dimensions is visible in
a separate window.
====Input window (caliber, projectile, propellant charge)====

{{ en:media::overview-expert-inputwin.png?30%&link}}

{{en:media::icon:icn_zoom_16x16.png}}**Use the buttons with the magnifying glass** to select or search for calibre, bullet and propellant powder.

{{en:media::icon:icn_pen_16x16.png}}**Input fields** in which you can enter or change values are marked with a small **pen symbol**. **Click in the input field** to edit a value. If you made a mistake and want to restore the original value, press the key **ESC**, or for a step-by-step undo, press the key combination **Ctrl-Z**. To confirm the entered value, you can click outside the input field or press the **ENTER/RETURN** key.

{{en:media::icon:icn_units_16x16.png}}**A small **ruler symbol** is located to the right of the edge** of a field. By clicking on this symbol, you can switch the displayed units. The setting made is saved and therefore remains in this position.

**Note:** If the window is too small to display all list entries, a scroll bar appears that can hide the icon. You can resize the columns at the top to make them visible again.

{{en:media::icon:icn_star_yellow_16x16.png}}**The yellow star** indicates that an input assistant is available for the current and any subsequent associated values (see paragraph "Tools & Assistants" at the [[en:doku:start|main page]]).

===Automatic Refresh===
**As soon as you have accepted/changed a value**, a new simulation calculation is **automatically** performed and displayed in the output window.

**=> More detailed information** and important notes on the input fields and the values to be entered can be found in chapter [[en:doku:inputfields|Input fields & values]].

====cartridge drawing====
{{ en:media::overview-cartridge-drawing.png?30%&link}}
**The cartridge drawing** in the area of the input window shows the **original specification** incl. all **original dimensions** in reduced view.

**In the upper right corner** you will find two symbols. The upper one opens the large view of the drawing in a separate window. The lower (PDF symbol) is the PDF document provided by the standardization organization (e.g. CIP). 

**Note** that the PDF documents are only (automatically) downloaded from the organization's website if the document has not yet been cached locally.

**Once you** have downloaded/displayed the document, it will be stored in the folder //**/pdf**// in the GRT program directory and will be available the next time you call it up.

====Output window (right)====
{{ en:media::overview-results.png?40%&link}}
**In the output window** the simulation results as well as helpful additional information are displayed. **Safety instructions & error messages** also appear here if the input parameters appear implausible, wrong or dangerous to the program.

  * **Do not blindly rely on error messages! It is possible to enter nonsensical values that lead to wrong results!**
  * Therefore, check your entries several times.
  * Measure it! e.g. case volume and bullet length from the database are **average values**. They vary from manufacturer, lot and in case of used cases also by the weapon used and processing of the case.

**=> A detailed description** of the output window can be found in chapter[[en:doku:outputfields|Result & output field]]].
