How to Import Files in Autodesk Inventor 2020

Find out in this video the best way to properly import different file formats for great results.


Hello, I'm James from Redcage and today I want to show you another quick tip trick and this time it’s going to be for importing files.

I have had this question a few times where people have asked me about the best method to use when importing STP files or IGS files.

In the end, it depends on the quality of the actual file you get.

Sometimes when you get files from websites or other suppliers, they don’t always make sure the files are cleaned up.

I want to go through the process to show you how to properly import a file.

There are actually two different methods to keep in mind because if there are multiple parts inside the actual STP file or IGS file you want to bring in, you can either go into a part and do a direct import into the part, making it a multi-body solid. 

You can also do a generic import on the CAD file which means it is going to kick it out to an assembly with its own parts.

You can also do the same to multi-body solids.

I am going to click on import CAD files where I have some import files ready to go.

I have an empty file among the other files just to show you some of the error messages you might get when you try to import.

I will start with one which will make it pretty easy and quick; an Allen Bradley push button.

Inside the import popup, we do a quick check up on the items we want to pull in. 

We would want to convert the model, make sure we are pulling in solids, surfaces, and wires if present.

We will turn it from composite to stitch.

Stitch is preferred especially so it actually heals the surfaces to make its own solids.

With the preferences set, select Load the Model so we can see how it looks before it is actually imported.

This is an important step because if it doesn’t show nicely, it would not show nicely during the actual import.

Spend the extra time and make sure what you see is going to work before you click on OK.

When you hit OK, it is going to generate the actual parts and will be ready to go.

Let’s try the import on a different object, in this case, an IGS file.

IGS files usually captures surfaces so it is not going to pull in too many solids however it will bring wires and surfaces in.

The parts options are a bit different because we are dealing with a single part and not an assembly so stitch is ideal.

We click on Load Model and then OK to bring the model in.

Once we have the IGS file imported, we to do a thick and offset to try and get a usable part.

Now, what happens if a file does not import right?

Go back into the 3rd party htm after going through previous steps and take a look at what happened.

It will give you a report on what went wrong with the file you tried to import.
