X1

X coordinate for the start point of the curve

Y1

Y coordinate for the start point of the curve

Z1

Z coordinate for the start point of the curve

X2

X coordinate for the end point of the curve

Y2

Y coordinate for the end point of the curve

Return Value

Sketch segment for the conic curve

This method creates a conic curve (circle, ellipse, parabola, or hyperbola) 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 call 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).
