Curve: Create Arc 2D  

 

 

 

 

Function

Creates independent Arcs for edge type. Only applicable on the work plane.  An arc is always drawn counterclockwise from the start point.

<Arc>

<Method>

The Center [(Abs x, y)], Start [(Abs x, y), (Radius, Start Angle)] and End [(Abs x, y), (Included Angle), (End Angle)] Locations are sequentially specified.
 

The Start [(Abs x, y)], any point on the Arc [(Abs x, y)] and End [(Abs x, y)] Locations are sequentially specified.
 

Create an Arc whose Start Location [(Abs x, y)] is at an end of an existing edge and tangent to the edge.  The End Location [(Radius, Included Angle)] is defined relative to the Start Location.  The new Arc exists as an independent edge, separated from the reference edge from which the new Arc was created.  Placing the mouse closer to one end of an edge defines the coordinates of the Start Location of the new Arc.
 

Location

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

<Method of Entering Coordinates>

ABS x, y

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

Enter a Radius and a rotational Angle (counterclockwise +) from the + X-direction on the Work Plane.
Included Angle

Enter an Angle of the Arc relative to the Start Location.
End Angle

Enter a rotational Angle (counterclockwise +) from the + X-direction on the Work Plane.

 

When entering coordinates using the mouse, the coordinates are automatically entered by left-clicking on the desired point, without having to press the [Apply] button.  However, when coordinates are typed in, either  [Enter] or [Apply] button needs to be pressed.

 

 

 

 

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.
