Zooming, Panning, and Rotating the View

There are a variety of ways to zoom, pan, and rotate the view within the Map View.

Zoom Dynamic Tool Dynamic Zoom Tool

Zooming can be done with the Dynamic Zoom tool in the following ways:

  • With the Dynamic Zoom tool, clicking on the Map View causes the viewing area to zoom by a factor of two around the clicked point. Holding down the Shift key while clicking causes the Map View to zoom out.
  • With the Dynamic Zoom tool, clicking and dragging a rectangle will cause the Map View to zoom to the rectangle.
  • If the computer mouse has a scroll wheel, scrolling the wheel up and down will cause the Map View to zoom in and out around the cursor location. This is especially helpful when another tool or command is active and you do not want to switch tools or stop the command. Holding down the Ctrl key slows down the scroll wheel zoom, providing more precision during zoom. Holding down the Shift key speeds up the scroll wheel zoom.

Navigate Backward Navigate Backward Tool

The Navigate Backward tool is used to step backward, showing previous map views that have been navigated to after zoom or pan operations.

Navigate Forward Navigate Forward Tool

The Navigate Forward tool is used to step forward, showing future map views that have been navigated to after zoom or pan operations.

Bookmark Views

Bookmark Views panel can be used to save the current view as a bookmark that can be restored later to return to the same location, zoom level, and 2-D/3-D orientation. Bookmarked views are stored in the Bookmarked Views panel.

Zoom Extents Zoom Extents Tool

The Zoom Extents tool is used to zoom to the extents of the GeoHECRAS model. If no HEC‑RAS elements are yet defined, then this command causes the Map View to zoom out to the extent of the current map layer.

Pan Pan Tool

Panning can be done with the Pan tool the following ways:

  • With the Pan tool, holding down the left mouse button while dragging moves the current view in the Map View.
  • If the computer mouse has a scroll wheel (or a middle button), holding it down and dragging moves the current view in the Map View. This is especially helpful when another tool or command is active and you do not want to switch tools or stop the command.

Rotate View Rotate Tool

While in 3D view mode, the Rotate tool can be used to rotate the view in the Map View. With the Rotate tool selected, holding down the left mouse button while dragging rotates the current view in the Map View.
