Create Sub Component

roce ure

1. Select the face where the profileso e rawn

2. Draw the profilesSimilar to the profile creation in sketch.

3. Create the model to cut or extrude

Lecture 6 12



Select the face to create the plane

.

boolstatus = Part.Extension.SelectByID2("", "FACE", 1,1, 0, False, 0, Nothing, 0)

2. Create the plane

Part.SketchManager.InsertSketch True

* The coordinate set in the selection set must be the point

on e n en e ace.

Lecture 6 13



Create the cut or extruded feature

. x ru e ea ure:use the FeatureExtrusion2 command

2. Cut feature: use FeatureCutpFeat = FeatureManager.FeatureCut ( sd, flip, dir, t1, t2, d1,d2, dchk1, dchk2, ddir1, ddir2, dang1, dang2, offsetReverse1,

, , ,normalCut, useFeatScope, useAutoSelect )

* all the parameters are similar to FeatureExtrusion2

Part.SketchManager.InsertSketch True

Dim line2, line3, line4, line5, base2 As Object
