Our Earth Pond and the tent of the sun.

In a previous article” SketchUp and flat Earth lesson 1 ” you were given indications about how to model a flat Earth pattern with Google Sketchup.

You will discover today how to create a component you can easily duplicate.

Our Earth Pond (are there more than one?)

Phase 1

Go to menu Edit and select the command “create component”.

Phase 2

A  window  will open and you should give a name to the component (I call it “Flat Earth”), then select the voice Glue to “any” and put a check in the voice “Cut opening”. These options could permit you, when you’ll  have created the component, to duplicate it any time you want and cutting the opening on the surface to create the Antarctic wall.

Phase 3

Inside the same window, before closing it, push the button “Set the component axis”. This will permit us to put the axis exactly in the center of the Earth. Thus when we duplicate the component, we will position it in an simpler way, by using the center of it. Once you have pushed the button with the cursor put the axis exactly at the origin of the reference system and set the x and the y axis direction by clicking respectively on the red and on the green axis.

Push the button “create” to finish the component creation.

When you now select the Earth you can see a blue square surrounding it, indicating that this is a component, i.e. a solid block.

Phase 4

If you select the “Flat Earth component” on the “component panel” site on the right, you can now position as many Earths as you want…

Ops…I have made an exagon…

The tent of the sun

You will model now the tent of the sun, i.e. the place of trajectories of the sun during the year.

Phase 1

Select the command line.

Track a line from the center of the Earth high 6660Km along the z axis. You have just to click on the origin, to move the cursor along the blue axis and type on the keyboard 6660 and then enter.

Phase 2

Select the command circle and track a circle with the center at the end of the line we have just made. Type 13320 for the radius and then type enter.

Phase 3

Select the command push-pull and extrude the circle downward typing 3330 and then pressing enter.

Phase 4

Track a line on a radius on the upper cylinder face.

Phase 5

Select the command move, select the end of the line on the circumference and move it toward the center of the cylinder. Type 6660 and then press enter.

Phase 6

Select the line and the upper and lower faces and delete them.

Phase 7

Color the conic surface with a transparent texture.

And here you are: that’s your Flat Earth with the tent of the sun.

If you want to understand better why the orbits of the sun are 6660km and 13320km, please read the article: Orbits of the sun.
