=====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?usp=sharing '''Sundial Calculator'''] - a Google Sheet
* '''[[Horizontal Sundial Designer]]''' -  '''[[CAD|Parametric]]''' design tool.
* '''[[Vertical Sundial Designer]]''' -  '''[[CAD|Parametric]]''' design tool.
* '''[[Polar Sundial Designer]]''' -  '''[[CAD|Parametric]]''' design tool.


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