The “Circle” tool

Same for the “Circle” tool. Again, click in the drawing window, move the mouse pointer until the desired size of radius for the circle is reached and click again, or type the size in the VCB box and click the Enter key on your keyboard.
With the first click you determine the center of the circle, the second click you determine the “End” and the diameter of the circle.

A circle has a “Object Properties” dialog where we can change the number of sides and the radius.
Standard circle is divided into 24 segments, or 24 lines. If you want to change it to eg 36 then you have a line for every 10 degrees. Do you follow?
36 lines times 10 degrees is 360 degrees, and a circle has 360 degrees.

But now I think I got carried away too far.

What you can not change is the “end point” of the circle. Therefore I suggest when you draw a circle, you draw it parallel to the green or the red axis. Just so that you always know where to find your   “End point”, and you do not have to search for it when you need it. For example, when we start using the  “Move” tool in cooperation with the push / pull tool.

What I can also say is that if you have a polygon with 24 segments or a circle with 24 segments, it just seems quite the same. This becomes clear when you start using the Push / Pull tool.
In the event that it is a polygon, this is divided into the number of segments that we have entered, and these can in turn be processed, for example, with a push / pull tool.
In the case of circle, that cannot happen.

If you want to show or hide these segments are in a circle, or in a polygon, click “View” in the menu bar and select “Hide geometry” in the drop-down menu.
Obviously, you first select the object.

The “hide geometry” is a toggle control, so if the segments are displayed when you clicked it,  they will be  hidden. If they are hidden, they will be shown when you click it.

 

The “Rectangle” tool

With the “Rectangle” tool, we draw a rectangle or a square.

Select the “Rectangle” tool in the tool bar, click in the drawing area at the place where you want to place the first corner of your square or rectangle.
Move the mouse pointer diagonally, and click again to determine the second vertex.
Again you can type the dimensions.
The width and height are separated by a character coma (,).

When you draw with the ‘click – move – click’ method, SketchUp will show a diagonal dotted line when the dimensions of a square of a “golden section” is reached.
For those who might not know what a “golden section” is, even i do not know. I looked it up on Google and it says, a ratio between the largest and the smallest lines, but honestly I do not understand.
But this is not important. Not for me.
