[Software introduction]

+ Overview.

 This software is an add-on software that expands the functions of Explorer.
 If you move the mouse cursor close to the file extension Jww, Jwc, the drawing information is displayed.

+ How to uninstall.

 To uninstall, go to "Add / Remove Programs" in the Control Panel.

+ Precautions.

1. If another operation is performed while the progress bar is displayed, Explorer's response becomes slow.

2. The icon image may not display all elements due to response time limitations.

3. Since drawing has a fixed display position, a place without a figure may be displayed.

4. Information may not be displayed in an incompatible version of the drawing.

5. In preview printing, it is not output to other than printers (PDF, XPS, etc.).

6. There is a time difference until the background color and image settings are reflected in the thumbnail. (Update by re-login)

In addition, expression about line width is not supported.


+ Simple usage instructions.

 Information is displayed when the mouse cursor is moved close to a file with the extension ".Jww" or ".Jwc" displayed in Explorer.

 The drawing image is displayed when the display method is switched to “Medium to Extra Large Icon”.

 If you switch from “View tab” to “Preview window” in Explorer, you can enlarge the display or switch the layer status.

 The following operations can be performed in the preview.

 <Panning>
  In addition to the up / down / left / right buttons, panning can be performed in the portrait and landscape areas (aspect ratio is less than 0.5) specified with the left mouse button.
  If the slider has focus, you can pan with the arrow keys.

 <Zooming>
  Specify the area with the left mouse button or move the slider button left and right.
  If the slider has focus, you can use the Page Up and Page Down keys to zoom in / out, and the Home key to reset the magnification.
  You can also zoom in / out by operating the mouse wheel in the display area. (*1)
  Double-click (or double-tap) to enlarge the display area. (Press the Shift key simultaneously to zoom out)

 <Switching>

  When pressed at the same time as the SHIFT key, it will be output with the previous printer settings.
