How to draw a 1/2 sphere

Gaieus

Andrew,

draw a horizontal circle
draw a vertical arc on top of it (starting and ending on opposite endpoints of the circle) and a line between the two endpoints to close the face
select the circles edges all around
select the Follof me tool and hit the face of your half circle.
you may wish to delete the initial cirlce and
depending on you getting a blue or white face of you semi-dome/hemisphere, you may wish to reverse it (right click, reverse face)

Thanks again..if i want to remove the base a the dome do you simply erase the base edge
Andrew

Gaieus

Not the base edge(for that is shared with the dome itself) but jzust the face. Click on it (once) and either hit the Del(ete) button or right click and choose "Erase".

Another way is to open the Components Menu / Shapes and select a 1/2 sphere. Too easy perhaps, but still an option.

dammerel

can it be re-sized to suit ?

Gaieus

Everything can be resized.

dammerel

how ? drag the edges ?

There is the scale tool. Select everything then the scale tool and start pulling one of the green "buttons".
While doing so, Shift key will toggle between uniform/non-uniform scale, Ctrl key will toggle between scaling about opposite point / centre.

I'm a few days into sketchup so bear with me ,

How do you create 2/3 spheres? I'm trying to put a doorway into a thick walled ball and don't know how to erase/divide up a sphere.

Also, in the welcoming message here there's a link for a semisphere tutorial that is 404'ed.

Well, Guite's examples may serve your needs. I do understand them so if there's any problem with them just tell us, please.

About the 404 error ("not found") - we had some problems with loosing some content so sorry for that. We'll try to replace it.

thanks. the intersect tool was what I needed to lop of the bottom of a sphere. Now to create a crust on the ball...

I don't know of a "crust" ruby. But you've sure got me curious.
