Curve: Create Circle 2D

 

 

 

 

Function

Create Circles of the edge type.  It is only applicable on the Work Plane.

 

 

 

 

Call

Geometry > Curve > Create on WP > Circle      

 

 

 

 

<Circle>

<Method>

Create a Circle by specifying its Center Location [(ABS x, y)] and Radius [(Radius)].
 

Create a Circle by entering the coordinates of one end [(ABS x, y)] of a diameter and the other end point [(ABS x, y), (REL dx, dy), (Length, Angle)].
 

Create a Circle by specifying the coordinates of three points [(ABS x, y)] on the Circle.
 

Create a Circle, which is tangent to two selected edges and has a specified radius.  Enter a radius and then select two edges.
 

Location

Enter the coordinates of the locations.  The coordinates are expressed in different forms noted below.
 

<Methods of Entering Coordinates>

ABS x, y

Enter 2-D coordinates for an absolute location on the Work Plane.
Radius

Enter the Radius of a circle.
REL dx, dy

Enter a distance relative to the Start Location on the Work Plane.
Length, Angle

Enter a relative distance from the Start Location and the rotational Angle (counterclockwise +) from the + X-direction on the Work Plane.

 

When we enter coordinates using the mouse, the coordinates are automatically entered by a left-click on the desired point, without having to press the Apply button.  However, when coordinates are typed in, either the Enter key or the Apply button needs to be pressed.

 

Make Face

Create a Face using Plane Patch.  This operation will not create a Circle of the edge type.

 

 

 

 

Notes

 

When 3-D coordinates are selected in 3-D space using Snap, the program will automatically project the point into 2-D coordinates of the Work Plane.
