Curve: Create Ellipse 2D

 

 

 

 

Function

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

 

 

 

 

Call

Geometry > Curve > Create on WP > Ellipse

 

 

 

 

<Ellipse>

Location

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

Input Center Location

Specify the coordinates of the Center Location [(ABS x, y)] of an Ellipse.
Input Major Radius and Location

Specify the end point [(Length, Angle), (ABS x, y)] of the Ellipse in the major (longer) axis direction.
Input Minor Radius

Specify the Radius of the Ellipse in the minor (shorter) axis direction.
 

< Methods of Entering Coordinates >

ABS x, y

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

Enter a Radius.
Length, Angle

Enter a relative distance from the Start Location and a 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 an Ellipse 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
