SolarTool: Sun-Path Menu

Sun-Path Context Menu

The Sun-Path Menu can be invoked within the context of the display area in the Sun-Path Window. You can display it using the Window Context Menu button whilst the mouse is within the main work area or by clicking and releasing the right mouse button.

It contains the following items:

Zoom to Fit

Zooms to fit the extents of the current display grid within the current view. Use this command to reset after zooming in or out.

Sun-Path Projection

Choosing an item in this sub-menu selects the type of projection used to translate the hemispherical sky dome onto a flat 2D drawing surface. See the Sun-Path Panel for more details.

Highlight in Diagram

The items in this sub-menu display elements of the sun-path diagram in bright yellow. This is useful for highlighting individual elements in discussions and educational seminars.

Show Shadow Angles

Displays lines of equal Vertical Shadow Angle overlaind on the sun-path diagram.

Show Shading Percentage

If the Shadowing value in the Sun-Path Panel is set to Percentage Shade, this option displays the percentage of the window in shade from each 10x10 deg. sky segment.

Show Daylight Factor Points

Displays 200 points within the diagram, spaced such that they each represent 0.5% of the daylight illuminance from a CIE Overcast Sky. This essentially means that the illuminance from the zenith is three times the illuminance from the horizon. For more detailed information on the CIE Skies and the distribution of points, see the Design Sky and Sky Point Overlays help page.

The idea is to visually count the number of points obstructed by overshadowing objects in the model.

Show Sky Factor Points

Displays 200 points within the diagram, spaced such that they represent 0.5% of the daylight illuminance based on the CIE Uniform Sky, in which all areas are equally weighted. For more detailed information on CIE sky types and the distribution of points, see the Design Sky and Sky Point Overlays help pages.

Show Annual Sun Path

Displays the path of the sun through the sky for the first day of each month of the year. The first six months (Jan-Jun) are shown as solid blue whilst the second six months (Jul-Dec) are shown as a dotted line. Each hour of the day is shown as a figure-8 due to the analemma effect.

Toggle World Map

Invokes an interactive world map, allowing you to click and drag to establish your exact location. You can resize this map in order to increase the accuracy of your mouse clicks.

Toggle 3D Model

Displays the 3D Model Window allowing you to edit and manipulate the window and its ahading devices.

Reset Shades

Resets all shading devices to the default single overhead shade.

Settings...

Displays the Settings Dialog box for adjusting application-wide options.
