    In the latest release of Autodesk Inventor (2024), we have had the introduction of a new Finish tool that allows the user to add surface finish details.

    There has always been the option to change the Appearance of an object in Autodesk Inventor, but any information about the surface finish or treatment needed to be added to the drawing, or more recently, 3D annotations. With the introduction of the new Finish tool, we can add rich data to the appearance for use in later processes.

    Below is a quick overview of the new tool and some of the features available.


    Finishes can be applied to models in both the part and assembly environment. The Finish tool is available in the Modify panel in the part environment and the appearance panel in the assembly environment.

    As the finish now acts like a feature, we can also apply multiple finishes to the same part or assembly by adding different finishes to different faces or associating a finish to a model state.

    For the example below, a toe blade from an excavator bucket, I have created several model states to show each stage of the manufacture process.


    The first model state is “raw stock” and does not have a Finish applied to it. All features after the initial extrusion are supressed.


    Next, we have the machining phase. In this model state we have added hole and chamfer features and included our first Finish feature.


    From the icon displayed in the model browser for Finish1, we see the surface texture symbol and editing the feature we can take a closer look at the inputs.


    We can select the faces we want to apply the finish to, which will provide a calculated total surface area.


     Specify the type of finish from either icons…



    or a drop-down list, depending on user preference.


    Once a finish type has been selected, we can specify a process. Each finish type has a set of processes associated to it as well as unique text fields. These processes are presets for the text information fields in the finish tool. For my example I want to show a machined finish, but from the list of processes available I do not have machining.


    Instead, I can select any of the processes in the list and change the pre-defined inputs to suit my preferred process. I will select Barrel Finishing, and the Description Field and Short Description Field both populate with “Barrel Finishing” (currently there is no option to add custom processes).

    Next, we have Appearance, and this will allow us to apply a standard appearance from the appearance libraries to our Finish surfaces. This can make it easier to understand which processes have been applied to certain surfaces, or produce a final appearance, like a paint finish.


    The last 3 boxes are free text boxes, so we can change them to suit our design requirement.


    We will see the benefits from this later in the blog, but for now, let’s have a look at our final Model state. Heat Treatment.


    Again, looking at the icon in the model browser we can see that this is a heat treatment process and editing the finish2 feature, we can look at the inputs.


    For this process I selected Heat treatment and then Case Hardening from the process drop down menu. By selecting Heat Treatment, we also get inputs for the hardness and required depth for case hardening.

    Not only is the finish tool very useful for denoting each finish type and/or process in the graphical display, it also allows us to reuse the information we have applied in our 2D manufacturing drawings.


    By creating Model states of our separate manufacture processes and implementing the new Finish tool into our design, we can quickly and easily reuse this information in our 2D data from existing tool sets.

    When creating view in our drawings, we have the option to specify which model state we want to View.


    This allows us to easily show our design intents using the appearances we applied through the finish tool.

    In addition to creating easy to understand visual information, we can also reuse the text data that we created using the standard text or leader text tools.

    A new Finish Parameter Type has been added to the text tool to allow us to insert the information from the Finish tool.


    By creating text blocks or leader text from this information, we start to partially automate our drawing data. Meaning if/when we change the information in the Finish tool, we automatically update our drawing.




    Or even display all the surface treatments and finishes for your entire assembly to help understand and plan production processes.


    I have found the Finish tool to be very useful already, and I can see a lot of potential for simplified methods of sharing information between engineers and manufacturers.
