Creating a circle with center, plane and radius

Circle can be used to create a circle.

There are several ways to specify the location of which location to create a circle, so let’s take a look at them.

Normally, position information is given to the Circle(P), but let’s look at it without giving it this time.

The radius of 50 is input to the Circle(R).

Then a circle with a radius of 50 appears at the origin (0,0,0) on the rhinoceros.

Thus, if no position information is given to the Circle(P), a circle centered at the origin is created.

By entering the coordinates using Panel, you can specify the center point where the circle will be created.

In this case, we entered 100,100,0.

Then a circle appears at x-coordinate 100, y-coordinate 100, and z-coordinate o.

Components used：①Construct Point ②Point ③YZ Plane ④Circle

You can also specify a position with a point.

This time, a point is created with Construct Point as the center point.

The position of the point is the same as before, with x-coordinate 100, y-coordinate 100, and z-coordinate o.

Thus, we have created a circle at the same location as before, centered at the point.

You can also create a circle in plane.

This time we use YZ Plane.

YZ Plane, so a vertically oriented circle has been created.
