What do I need to build a sundial?

GEOGRAPHICAL COORDINATES

It is necessary to know the exact geographical coordinates (latitude and longitude) of the location where the clock will be placed, if it is fixed, or where the clock will be used, if it is portable.

GEOMETRIC PARAMETERS

For the Vertical, Oblique and Multi-face types, it is necessary to know the orientation (decline) of the wall.

For the Horizontal, Equatorial and Cylindrical types it is necessary to know the longitude of the location.

Finally, for the oblique types it is necessary to know the inclination of the wall.

COMPUTER PROGRAM

It is necessary to obtain a complete version of the program SUNWATCH3D 2.0.

TO OUTPUT THE PROGRAM RESULTS

It is necessary to obtain the complete version to be able to transfer it to the final wall. For this a compatible Windows printer or a CAD program is required to obtain a real scale print or plot of the sundial design.
