Create workpoint at the intersection of two axes C#

[Anonymous]

I am trying to create a workpoint at the intersecion of two Z axis of two hand picked frame generator members

here's my code so far

ComponentOccurrence co1 = (ComponentOccurrence)(invapp.CommandManager.Pick(SelectionFilterEnum.kAssemblyLeafOccurrenceFilter, "Pick first Part"));
ComponentOccurrence co2 = (ComponentOccurrence)(invapp.CommandManager.Pick(SelectionFilterEnum.kAssemblyLeafOccurrenceFilter, "Pick second Part"));

PartComponentDefinition cd1 = (PartComponentDefinition)co1.Definition;
PartComponentDefinition cd2 = (PartComponentDefinition)co2.Definition;

WorkAxis cd1Z = cd1.WorkAxes["Z Axis"]; ///vb and vba sample d1.WorkPlanes.item("3")

WorkAxis cd2Z = cd2.WorkAxes["Z Axis"];

AssemblyDocument thisDoc = (AssemblyDocument)invapp.ActiveDocument;

object tempAxis1 = null;
co1.CreateGeometryProxy(cd1.WorkAxes["Z Axis"], out tempAxis1);
//thisDoc.ComponentDefinition.AdjustProxyContext(tempAxis1);
WorkAxis x1 = tempAxis1 as WorkAxis;

object tempAxis2 = null;
co2.CreateGeometryProxy(cd2.WorkAxes["Z Axis"], out tempAxis2);
WorkAxis x2 = tempAxis2 as WorkAxis;

WorkPoint px = thisDoc.ComponentDefinition.WorkPoints.AddByTwoLines(x1.Line, x2.Line, true);

I'm not sure what version you're on, but the Inventor 2017 API documentation states that the WorkPoint.AddByTwoLines method is not supported within an assembly.  Check the API documentation for your version.

Hi,

Inventor 2020 doesn't support it in the assembly also.

WorkPoints.AddByTwoLines Method 

> This method is not currently supported when creating a work point within an assembly.

any alternative methods??

cause the reason i need the point is to measure it to the start and the end plane of the frame generator part

What Inventor does when you use AddByTwoLines in assembly environment (from UI) is creating a point and constraining it to the two axes.

I'm not experienced with C# but i'm sure you'll be able to translate from this example code in iLogic

Dim oDoc As AssemblyDocument = ThisDoc.Document
Dim oAxes As WorkAxes = oDoc.ComponentDefinition.WorkAxes
Dim A1 = oAxes.Item("Z Axis") 'This should be first axis proxy instead
Dim A2 = oAxes.Item("X Axis") 'This should be second axis proxy instead
Dim oNewPoint As WorkPoint = oDoc.ComponentDefinition.WorkPoints.AddFixed(ThisApplication.TransientGeometry.CreatePoint())
oDoc.ComponentDefinition.Constraints.AddMateConstraint(oNewPoint, A1, 0)
oDoc.ComponentDefinition.Constraints.AddMateConstraint(oNewPoint, A2, 0)

ComponentOccurrence co1 = (ComponentOccurrence)(invapp.CommandManager.Pick(SelectionFilterEnum.kAssemblyLeafOccurrenceFilter, "Pick first Part"));
ComponentOccurrence co2 = (ComponentOccurrence)(invapp.CommandManager.Pick(SelectionFilterEnum.kAssemblyLeafOccurrenceFilter, "Pick second Part"));

 

PartComponentDefinition cd1 = (PartComponentDefinition)co1.Definition;
PartComponentDefinition cd2 = (PartComponentDefinition)co2.Definition;

WorkAxis cd1Z = cd1.WorkAxes["Z Axis"]; ///vb And vba sample d1.WorkPlanes.item("3")

WorkAxis cd2Z = cd2.WorkAxes["Z Axis"];

 

AssemblyDocument thisDoc = (AssemblyDocument)invapp.ActiveDocument;

 

Object tempAxis1 = null;
co1.CreateGeometryProxy(cd1.WorkAxes["Z Axis"], Out tempAxis1);
//thisDoc.ComponentDefinition.AdjustProxyContext(tempAxis1);
WorkAxis x1 = tempAxis1 As WorkAxis;

Object tempAxis2 = null;
co2.CreateGeometryProxy(cd2.WorkAxes["Z Axis"], Out tempAxis2);
WorkAxis x2 = tempAxis2 As WorkAxis;

 

WorkPoint px = thisDoc.ComponentDefinition.WorkPoints.AddFixed(invapp.TransientGeometry.CreatePoint());
thisDoc.ComponentDefinition.Constraints.AddMateConstraint(px, x1, 0);
thisDoc.ComponentDefinition.Constraints.AddMateConstraint(px, x2, 0);

I tried to do it in C#, maybe it'll work 🙂

i did rewrote it to this but thanks

and also the conversion to the proxy is unnecessary 

this will do

WorkPoint px = thisDoc.ComponentDefinition.WorkPoints.AddFixed(invapp.TransientGeometry.CreatePoint());

thisDoc.ComponentDefinition.Constraints.AddMateConstraint(px, tempAxis1, 0, InferredTypeEnum.kNoInference, InferredTypeEnum.kNoInference);
thisDoc.ComponentDefinition.Constraints.AddMateConstraint(px, tempAxis2, 0, InferredTypeEnum.kNoInference, InferredTypeEnum.kNoInference);

You are right that assigning tempaxis1 to x1 is unnecessary since tempaxis1 already is the proxy object of the members z-axis 🙂

but it has to be a proxy.
