Diameter instead of radius

pilou

In the case of the inclined circle above

an infinite number of planes around a line

But only one with a diameter // to the ground ! (i believe that will be a tricky plug
(in fact 2 if your circle has a color different recto verso

Cool, I like that 100/2 option. Exactly what I am looking for when I am too lazy to divide D to get R

Thanks!

Silly question: Why does Layout let you set a circle by diameter... namely typing for exampe: 5" d in the toolbar to get a 5" diameter circle and Sketchup itself does not?

Two different programs.

It does allow - with a bit of basic calculation input - except when you also want to use the unit (it seems). I use a (centi)metric template and I can enter (say) 100/2 and it will draw a circle with an 50cm radius (i.e. 100cm dia).

I guess this does not help much with architectural imperial template for instance...

I too would like this. It takes too much time to switch to a separate calculator to figure out a complex circle's radius. I thought the /2 idea would work but it doesn't I have a Sketchup model that is set to decimal inches. I keep trying to draw a circle with a 1.25" diameter. If I type 1.25/2 in the box I get a circle with a radius of 1.25. I've tried a number of different ways of typing this to no avail.

I use the scale tool. I draw the circle, use the scale tool by clicking on corner holding cntl key. Start the move and type in 2 or .5 to double or halve the circle

I've just practiced doing the math in my head. I must say I've gotten faster at it with practice. It really isn't a big problem for me.

I would find scaling a circle after I've drawn it kind of a pain especially if it is drawn on something else in a location where the larger circle would have to cross other geometry.

So try 125/200 instead of 1.25/2 .

The technique of entering n/m works only because SketchUp's measurements box accepts fractions, not because it implements a divide operator as such. In a fraction both n and m must be integers. Any other type does not get treated as a numerator or denominator of a fraction.
