=====Description=====

'''DT Online''' has created online tools to help calculate the '''Hour Lines''' for different '''Sundial''' types. They are:
* [https://docs.google.com/spreadsheets/d/1KqtSFP4Xxz4WlwKROGcv7w-YDGwW_7bGwek0IqSSgTk/edit#gid=2035122671 '''Sundial Calculator'''] - a Google Sheet ''(Google account needed for editing)''
* '''[[Horizontal Sundial Designer]]''' -  '''[[CAD|Parametric]]''' design tool.
* '''[[Vertical Sundial Designer]]''' -  '''[[CAD|Parametric]]''' design tool.
* '''[[Polar Sundial Designer]]''' -  '''[[CAD|Parametric]]''' design tool.

See '''[[Packaging Designer User Guide]]''' for further information.


=====Features and Applications=====

The '''DT Online Design Tools''' will calculate either the number of degrees to measure the '''Hour Line''' angle away from the Noon position or the distance away from it as appropriate to the type of '''Sundial'''.

* The '''Google Sheets''' [https://docs.google.com/spreadsheets/d/1KqtSFP4Xxz4WlwKROGcv7w-YDGwW_7bGwek0IqSSgTk/edit#gid=2035122671 '''Sundial Calculator'''] accepts the Sundial location '''[[Latitude]]''' as the main input and returns values for all '''Hour Lines''' as follows:
** for Horizontal and Vertical Sundials, the number of degrees each one falls away from the central Noon line;
** for Polar Sundials, the distances along the '''Dial Plate''' of each '''Hour LIne''' for a given height of '''[[Sundials and Gnomons|Gnomon]]'''.

In order to use the Google Sheets,  you need to be logged in to a google account.  You can then click on 'Make A Copy' from the 'File' menu to give you a spreadsheet you can work on.</span>

* The '''[[Horizontal Sundial Designer|Horizontal]]''' and '''[[Vertical Sundial Designer|Vertical Sundial Designers]]''' accept the Sundial location '''[[Latitude]]''' and your chosen dimensions for the completed '''Dial Plate''' as inputs and output the following:
** a table showing the number of degrees each '''Hour Line''' falls away from the central Noon line;
** a CAD drawing of the resulting '''Dial Plate''' which can be used as a '''[[Template]]'''.
* The '''[[Polar Sundial Designer]]''' offers a choice of either a '''Flat Dial Plate''' or a '''Curved Dial Plate''' and a table which enables inputs of your chosen dimensions for the completed '''Dial Plate''' ''(e.g. Gnomon height, width of plate, radius of curvature for curved plate option)'' and outputs the following:
** a table showing the distances each '''Hour Line''' away from the central Noon line;
** CAD drawings of elevations of the resulting '''Dial Plates''' plus '''[[Template|Templates]]''' which can be used to transfer the '''Hour Lines''' on to your chosen material ''(note that curved plates can provide for a greater range of hours)''.
