How can you find the intersection between two curves in Autodesk Inventor using the API?

HANDBRAKE is one of the most popular and free video conversion tools.

It is open source, easy to use, and works on Windows and Mac.

Sheets in Inventor are named using the Sheet.Name property. By default, they follow a simple pattern:

• Sheet1, Sheet2, etc.
• You can rename them manually or programmatically using:

sheet.Name = "Assembly Overview"

You can delete sheets using the Inventor API or iLogic. Here's a VB.NET-style snippet that safely deletes all sheets except the first:

Dim oDoc As DrawingDocument = ThisApplication.ActiveDocument
Dim oSheets As Sheets = oDoc.Sheets

' Delete all sheets except the first one
Do While oSheets.Count > 1
    Dim lastSheet As Sheet = oSheets.Item(oSheets.Count)
    lastSheet.Delete()
Loop

No, Apprentice Server cannot export Inventor part files (*.ipt) to formats like SAT, IGES, or STEP.

Recommended Steps

1. Ensure All Changes Are Saved

   
   ' After updating properties
   oDoc.Save()
   

2. Force Update of Drawing Views

   
   oDrawingDocument.Update()
   

3. Use Inventor's Built-in DWF Export

   
   oDrawingDocument.SaveAs("C:\Path\To\File.dwf", True)
   

4. Verify Property Source in Title Block
   • Open the title block definition.
   • Check if the field is pulling from <Current Drawing> or <Primary Model>.
   • If it's <Primary Model>, ensure the model file is updated and saved.

Use Custom iProperties (Simple Metadata Storage)

Inventor documents support custom iProperties, which are ideal for storing small text data like tags, GUIDs, or configuration flags.

Writing iProperty in VC++ (via COM):

CComPtr<Inventor::Document> pDoc = ...; // Get active document
CComPtr<Inventor::PropertySet> pPropSet;
HRESULT hr = pDoc->PropertySets->Item(CComVariant("Inventor User Defined Properties"), &pPropSet);

CComPtr<Inventor::Property> pProp;
try {
    pPropSet->Add(CComVariant("MyTextData"), CComVariant("Hello from VC++"), CComVariant("MyCustomProp"), &pProp);
} catch (...) {
    // If already exists, update it
    pPropSet->Item(CComVariant("MyCustomProp"), &pProp);
    pProp->PutValue(CComVariant("Updated Text"));
}
