Autodesk.inventor.interop.dll • Recent & Updated

Do not distribute Autodesk.Inventor.Interop.dll with your application. Your installer should require the matching Inventor version to be pre‑installed. For a cleaner deployment, use the Autodesk Inventor API SDK and reference the assembly via HintPath pointing to an environment variable like $(INVENTOR_DIR).

To develop a 3D solid text using the Autodesk.Inventor.Interop.dll, you must first reference the library in your project and then use the EmbossFeatures or ExtrudeFeatures objects to turn a text sketch into a solid body. 1. Setup the Environment

You must add a reference to the Autodesk.Inventor.Interop.dll in your Visual Studio project to access the Inventor API .

Location: Typically found in C:\Program Files\Autodesk\Inventor 20xx\Bin\Public Assemblies. autodesk.inventor.interop.dll

Properties: Set "Embed Interop Types" to False and "Copy Local" to True to ensure proper runtime referencing from the Global Assembly Cache (GAC). 2. Implementation Steps

Developing solid text involves a three-step programmatic workflow: A. Create a Sketch and Add Text

Create a PlanarSketch on a part face or work plane, then add a TextBox containing your string.

' Example: Creating a text box on a sketch Dim oSketch As PlanarSketch = oCompDef.Sketches.Add(oWorkPlane) Dim oPoint As Point2d = oTransGeom.CreatePoint2d(0, 0) Dim oTextBox As TextBox = oSketch.TextBoxes.AddFormattedText("Your Text Here", oPoint) Use code with caution. Copied to clipboard B. Select the Profile Do not distribute Autodesk

The text box acts as the profile for your 3D feature. Use the Profile property of the sketch to capture the text geometry. C. Apply the 3D Feature You have two primary options to create the "solid" effect:

Embossing: Use the EmbossFeatures Object to raise or recess text relative to a face. This is ideal for curved surfaces.

Extruding: Use ExtrudeFeatures to create a standard 3D solid from the text profile. This is better for simple, flat-surface 3D text. Different version of Autodesk.Inventor.Interop.dll

If you’ve ever opened the Object Browser in Visual Studio while working with Autodesk Inventor’s API, you’ve likely seen autodesk.inventor.interop.dll. It looks like just another reference, but misunderstanding it can lead to broken add-ins, version conflicts, and deployment headaches. Have you run into a specific build, runtime,

In this post, I’ll explain what this DLL actually is, when you need it, and how to use it correctly in your Inventor plug-ins.

The file is typically installed with the Autodesk Inventor SDK or the software itself.

Important: When developing an add-in, you usually reference this DLL from the installed directory. When distributing your application, you generally rely on the user having Inventor installed, or you include the specific redistribution policy defined by Autodesk.

Simply put, autodesk.inventor.interop.dll is a Runtime Callable Wrapper (RCW). Inventor’s core API is written in native COM (Component Object Model). To allow .NET languages (C#, VB.NET) to talk to that COM interface, Visual Studio generates an interop assembly. This DLL acts as a bridge, marshaling calls between managed (.NET) and unmanaged (Inventor) code.

You typically find it in two places:
