VBA with Sketch

Lecture 6 1Lecture 1



Creating a lineDim swA As Ob ect

Dim Part As Object

Sub main()

e sw pp = pp ca on. or s

Set Part = swApp.ActiveDoc

Part.CreateLine2 p1x, p1y, 0, p2x, p2y, 0

‘OR

Dim line1 As Object

Set line1 = Part.CreateLine2 (p1x, p1y, 0, p2x, p2y, 0)

End Sub

Condition: the sketch plane is already been set

Lecture 6 2



What we are going to cover

n y o raw: arc, c rc e,

Selection set

Setting the sketch plane

Lecture 6 3



Arc: CreateArcByCenter

retval = ModelDoc2.CreateArcB Center 1x 1 1z 2x 2 2zp3x, p3y, p3z )

This method creates an arc by center in this model document.

double 1x X coordinate for center oint in meters(double) p1y Y coordinate for center point in meters(double) p1z Z coordinate for center point in meters

(double) p2x X coordinate for start point in meters(double) p2y Y coordinate for start point in meters(double) p2z Z coordinate for start point in meters(double) p3x X coordinate for end point in meters(double) p3y Y coordinate for end point in meters(double) p3z Z coordinate for end point in meters

Output:(VARIANT_BOOL) retvalTRUE if successful, FALSE otherwise

boolstatus = Part.CreateArcByCenter(0, 0, 0, 5, 0, 0, -5, 0, 0)

Lecture 6 4



What is the difference?

return TRUE is the object successfully created andFALSE otherwise

Retval:LPDISPATCH

return pointer to the created object

Method to draw the arc using LPDISPATCH1. Part.CreateArc2 0, 0, 0, 5, 0, 0, -5, 0, 0, 1

2. Dim arc1 As ObjectSet arc1 = Part.CreateArc2(0, 0, 0, 5, 0, 0, -5, 0, 0, 1)

Lecture 6 6



line properties.swp

What is the difference?

-. , , , , , , , , ,

Just draw the arc

Set arc1 = Part.CreateArc2(0, 0, 0, 5, 0, 0, -5, 0, 0, 1)

Draw the arc and name the arc as arc1. Therefore, we

etc

Properties can be changed

=

arc1.Width = 3

arc1.Style = 2

Other Create Sketch Entities

retval = ModelDoc2.CreateEllipse2 ( centerX, centerY,centerZ, majorX, majorY, majorZ, minorX, minorY,

Point retval = ModelDoc2.CreatePoint2 ( x, y, z )

Spline

retval = ModelDoc2.CreateSpline ( pointData )

*point data : array form
