Parameters

XC

X coordinate for the ellipse center point

YC

Y coordinate for the ellipse center point

Zc

Z coordinate for the ellipse center point

XMajor

X coordinate for a point on the ellipse and on the major axis

YMajor

Y coordinate for a point on the ellipse and on the major axis

ZMajor

Z coordinate for a point on the ellipse and on the major axis

XMinor

X coordinate for a point on the ellipse and on the minor axis

YMinor

Y coordinate for a point on the ellipse and on the minor axis

ZMinor

Z coordinate for a point on the ellipse and on the minor axis

X1

X coordinate for counter-clockwise elliptical arc start point

Y1

Y coordinate for counter-clockwise elliptical arc start point

Z1

Z coordinate for counter-clockwise elliptical arc start point

X2

X coordinate for counter-clockwise elliptical arc end point

Y2

Y coordinate for counter-clockwise elliptical arc end point

Z2

Z coordinate for counter-clockwise elliptical arc end point

Direction

• +1 : Go from the start point to the end point in a counter-clockwise direction
• -1 : Go from the start point to the end point in a clockwise direction

Return Value

This method creates a full circle in the active 2D sketch. If a sketch is not active, then a new sketch is created. You can check for an active sketch using ISketchManager::ActiveSketch.

ISketchManager::AddToDB and ISketchManager::DisplayWhenAdded increase performance during entity creation by adding entities directly to the SOLIDWORKS database.

ISketchManager::AddToDB also avoids some of the peculiarities involved with creating entities via the user interface, such as inferencing, automatic relations, and snapping to the grid. Adding entities directly to the database also significantly increases the performance of this method. When you are done creating entities, it is important to ISketchManager::AddToDB(False), to restore SOLIDWORKS to its normal operating mode.

This method also works with ISketchManager::DisplayWhenAdded. If you have called ISketchManager::AddToDB(True), additional performance can be gained by calling ISketchManager::DisplayWhenAdded(False) to disable immediate display of entities as they are added to the database. When you are done creating all of your sketch entities, you must redraw your document window (see IModelView::GraphicsRedraw or IModelView::IGraphicsRedraw) to see the entities you added. You should also restore the original display settings by calling ISketchManager::DisplayWhenAdded(True).

To create a complete ellipse, use ISketchManager::CreateEllipse.
