Parameters

XC

X coordinate of the circle center point in meters

YC

coordinate of the circle center point in meters

Zc

Z coordinate of the circle center point in meters

X1

X coordinate of the start point of the arc in meters

Y1

coordinate of the start point of the arc in meters

Z1

Z coordinate of the start point of the arc in meters

X2

X coordinate of the end point of the arc in meters

Y2

Y coordinate of the end point of the arc in meters

Z2

coordinate of the end point of the arc in meters

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 partial arc 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 increases the performance of this API. 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 that you added. You should also restore the original display settings by calling ISketchManager::DisplayWhenAdded(True).
