How do you create a sphere?

Reuben_Abraham

I have figured out a way, but I'm quite sure there's a much simpler way to do it...
Please include any videos or gifs if possible, thanks.

You can create a sphere in 2 steps. Create a sketch and draw an arc or circle and then use the revolve tool. 
Here's an example: https://cad.onshape.com/documents/f46a38416ac2855162ef7bed/w/ee19045eebb62fb7898e525d/e/9060850a21912e090e6916e9

oh, yes that is way simpler. My old method was to create a semicircle, create a new plane perpendicular to it and then draw a circle, and THEN revolve. thanks for the help!

I created a 1.5" diameter solid cylinder, 1.5" long.  Then selected both edges and used the filet tool and set the radius to the maximum allowable value of 0.75 in.  It sure looks like a sphere, and was super simple.  All dimensions in the generated drawing indicate a 1.5" diameter sphere.

Liar. You CAN'T REVOLVE THE EDGE.

You can revolve an edge as a surface. You can also create an enclosed sketch and revolve as a solid.

@davin_song
You would have to split the circle in half to revolve the edge as a surface.

This really is why Onshape is behind the the 8-ball from the start. Even basic shapes are crazy hard to create for a beginner, with no real thought seemingly ever having been put into ease of uptake. Doing the simplest things takes hours of endless tutorials and youtube videos. And yes, I know everyone has their "one weird trick" that makes it easy to do a particular thing, but honestly would it be *that* hard to add some basic primitives? Even making a sphere means 90% of users fall into the self-intersecting shape rabbit hole, and that's their first experience of Onshape.

I've already successfully talked another dev team into this.

So, lets's try agian ;0) :

• A spere can be defined by a center point and a radius. Easy.
• A cylinder can be defined by a line and a radius. Easy.

Why not allow the thicken tool to work on curves and points?

• Create a sphere by thickening a point.
• Create a cylinder by thickening a line.
• Create a bent rod thing by thickening a curve.
• Create a bent rod thing with straight areas and rounded ends by thickening a chain of point, line, curve, point.
  

That would be very easy and also fast to edit after the fact.

Sample: One sketch - select all - one thicken feature.

I've been using CAD at my dayjob since the mid 90's. I don't think I ever made a sphere for anything work related. At home for hobby I did a few times to model billiard balls. I don't see the big deal with making a sphere using a revolve. Once you know how to do it, it just takes a few seconds, and you'll never forget how to do it.
