Parameters

XC

X value of the circle center point in meters

YC

Y value of the circle center point in meters

Zc
Z value of the circle center point in meters
Xp1
X value of the start point of the arc in meters
Yp1

Y value of the start point of the arc in meters

Zp1
Z value of the start point of the arc in meters
Xp2

X value of the end point of the arc in meters

Yp2
Y value of the end point of the arc in meters
Zp2
Z value 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 IModelDoc2::GetActiveSketch2 or IModelDoc2::IGetActiveSketch2.

For COM applications, the object pointer returned from this method can be used to call any APIs on the ISketchSegment interface. The underlying ISketchArc object can be obtained using QueryInterface on the returned ISketchSegment object.

OLE applications can define a new ISketchSegment or ISketchArc object using the returned Dispatch pointer. Visual Basic applications interpret the pointer for you automatically, so you can use the returned object to call ISketchSegment or ISketchArc functions.

IModelDoc2::SetAddToDB and IModelDoc2::SetDisplayWhenAdded increase performance during entity creation by adding entities directly to the SOLIDWORKS database.

  • IModelDoc2::SetAddToDB 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 IModelDoc2::SetAddToDB(false), to restore SOLIDWORKS to its normal operating mode.
  • This method also works with IModelDoc2::SetDisplayWhenAdded. If you have called IModelDoc2::SetAddToDB(True), additional performance can be gained by calling IModelDoc2::SetDisplayWhenAdded(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 IModelDoc2::GraphicsRedraw2) to see the entities that you added. You should also restore the original display settings by calling IModelDoc2::SetDisplayWhenAdded(True).
