Quickest/Easiest Way to Create a Sphere?

Rich O Brien

Screenr allows immediate upload to YT.

I'll look into adding a Screenr bbcode but not for all member levels as iframe insertion is a security risk.

Yep I saw the YT link, but it's another step and I don't want a YT account.

Yes, if you start it from the origin, it is easier. But finding the centre of the circle is not too hard either if you hover over the perimeter a bit first.

This is my shot at it

Any place that not at the origin

I think we have glossed over the main issue in Chris' question, they are having trouble getting the second circle in the centre of the first. This is an inferencing issue.
I did this vid for finding the centre point.

Use Set Center Point plugin. Sorry I just saw where you say "without additional plugin"

Hi folks.

Once you know the trick it shall takes less than 10 seconds to create a sphere.

Read all the text notes in this sketchUp file for ideas:

we create a flat circle then create another vertical circle, but first we have to find the center on the flat circle to place the vertical circle. And finding the center is sometimes difficult. I tell them to draw a line in the middle of the circle, but sometimes even that is very difficult because by default, sketchup doesn't always draw the line in the middle. Sometimes its off-center.

I've highlighted what seems to be the main issue. They know how to create the sphere, it's the alignment that has them confused, which is what I addressed in my second video.

I try to get my students to do a sphere, we create a flat circle then create another vertical circle, but first we have to find the center on the flat circle to place the vertical circle. And finding the center is sometimes difficult. I tell them to draw a line in the middle of the circle, but sometimes even that is very difficult because by default, sketchup doesn't always draw the line in the middle. Sometimes its off-center.

Have them display crosshairs

Easiest and fastest way yet
only two tools were used with crosshair display on:

2 times circle tool used
2 times follow-me tool were used to touch a same aline tangent points
that's it done.
