Trying to rotate an assembly occurance

[breinkemeyer]

I'm trying to rotate the end shaft in the drawing 90° along the X axis.  this is my code.  instead of rotating the shaft is moved to the opposite end.  What am I missing?

AssemblyDocument oDoc;
AssemblyComponentDefinition oCompDef;
ComponentOccurrence oCC;
Matrix oTransform;

oDoc = (AssemblyDocument)oInventorApp.ActiveDocument;
oCompDef = oDoc.ComponentDefinition;
int i = oCompDef.Occurrences.Count;
oCC = oCompDef.Occurrences[i];
oCC.Grounded = false;
oTransform = oCC.Transformation;
oTransform.SetToRotation(90.0 * DtoR, oITransGeo.CreateVector(1, 0, 0), oITransGeo.CreatePoint(1024.7, 0, 0));
oCC.Transformation = oTransform;
oCC.Grounded = true;

hello @breinkemeyer, it might be possible that you're not using the right axis to rotate around you could try adjusting your vector. you also should get the coördinates of the occurrence pre rotation so you can move the shaft back after rotation since rotating might reset the position to origin. this would look something like this (my code is VB.net:

rotatie = rotatiehoek * (Math.PI / 180)

Dim occ As ComponentOccurrence
occ = ThisApplication.CommandManager.Pick(SelectionFilterEnum.kAssemblyOccurrenceFilter, "Selecteer component")

Dim currentpos As Matrix = occ.Transformation

Dim centerpoint As WorkPoint = occ.Definition.Workpoints.item(1)
Dim centerproxy As WorkPointProxy : Call occ.CreateGeometryProxy(centerpoint, centerproxy)

Dim Xcoor As Double = Round(centerproxy.Point.X)
Dim Ycoor As Double = Round(centerproxy.Point.Y) 
Dim Zcoor As Double = Round(centerproxy.Point.Z*10)

Dim oPosition As Matrix = ThisApplication.TransientGeometry.CreateMatrix()

Call oPosition.SetToRotation(rotatie, ThisApplication.TransientGeometry.CreateVector(0, 0, 1), ThisApplication.TransientGeometry.CreatePoint(0, 0, 0))

Call currentpos.TransformBy(oPosition)
Call occ.SetTransformWithoutConstraints(currentpos)

Call currentpos.SetTranslation(ThisApplication.TransientGeometry.CreateVector(Xcoor, Ycoor, Zcoor/10))	
Call occ.SetTransformWithoutConstraints(currentpos)

occ.Grounded = True

I hope this might help!

Just an other solution where i was working on:

AssemblyDocument oDoc = (AssemblyDocument)ThisApplication.ActiveDocument;
AssemblyComponentDefinition oCompDef = oDoc.ComponentDefinition;
int i = oCompDef.Occurrences.Count;
ComponentOccurrence oCC = oCompDef.Occurrences[i];
oCC.Grounded = false;

var orgMatrix = oCC.Transformation;
var rotationMatrix = oITransGeo.CreateMatrix();
rotationMatrix.SetToRotation(90.0 * DtoR, oITransGeo.CreateVector(1, 0, 0), oITransGeo.CreatePoint(1024.7, 0, 0));

var newMatrix = oITransGeo.CreateMatrix();
newMatrix.TransformBy(orgMatrix);
newMatrix.TransformBy(rotationMatrix);

oCC.Transformation = newMatrix;
oCC.Grounded = true;

That did the trick, thanks so much!
