Tolerance analysis reporting

00:08

Hello, my name is Thom Tremblay from Concepts and Design.

00:12

This course is on a modern approach to creating documentation.

00:17

The learning path for this course, we'll look at annotating a 3D model and sharing the annotated model,

00:24

analyzing tolerance relationships in an assembly and then sharing the results of that analysis.

00:32

This course will be the fifth and final chapter in the series and it will focus on exporting the data of the analysis results,

00:41

including generating a report.

00:43

We'll see what options you have for managing existing analysis in the model.

00:49

And we'll take a look at another option for doing tolerance stack up calculations.

00:55

Opening the Tolerance Analysis stack ups assembly, we can again return to the Annotate tab and then to Tolerance Analysis.

01:05

When the Tolerance Analysis opens, the two stack ups are still present in the model.

01:12

You can return to one of the tolerant stack ups by selecting the arrow,

01:15

and it will give you all of the information that you previously saw, when you did the analysis.

01:22

From here, you can continue to experiment with the tolerances.

01:26

For now, though, let's focus on getting this information available to others.

01:32

With Stack Up 1 active, I'll zoom in on the information from that analysis.

01:38

In the report panel, I'll select Take Snapshot.

01:42

This will prepare a snapshot that can be included in the report.

01:47

After the snapshot has been taken, if I relocate the model, then select Show Snapshot,

01:54

it will revert the model back to the screen position of the snapshot.

02:00

If I activate Stack Up 2, you'll see that the annotation for Stack Up 1 disappears and the information for Stack Up 2 is present in the model.

02:11

Let's create another snapshot.

02:14

And now we're ready to start sharing the information.

02:18

We can import previous tolerant stack up analysis files into Inventor.

02:24

We can also export them.

02:26

By selecting the Export tool, we can give the file a name and a location and save it.

02:35

This is information that we can share with others for their review of our work.

02:41

Another way to share the information is to generate a report.

02:46

By selecting the Generate Report tool, we'll be asked to give the file a name.

02:52

This will be an html document that we can easily pass to others.

02:57

After the report is generated, it will appear in whatever our default browser is.

03:03

We can scroll down through the information and on the left are links that will quickly take the viewer to a certain section.

03:12

All of the key information on the tolerance stack up is included, including any of the graphical information.

03:22

At any time in the Tolerance Analysis tab, if you refer back to the summary of 1D tolerance stack ups,

03:30

you can go to any of these studies, go to edit them, rename them or delete them if you want to remove them from the model.

03:41

Finally, I'd like to remind you that there is another tolerance calculator built into Autodesk Inventor.

03:48

If you go to the Design tab where the Design Accelerator tools are stored, you can go to the Power Transmission panel, expand it,

03:57

and find a Tolerance Calculator along with the limits in fits calculator and a press fit calculator.

04:05

Starting the tolerance calculator, you can add as many dimensions as you like.

04:10

The final role listed will be the resultant dimension.

04:14

So by going in and making some quick modifications for the tolerances and the nominal dimension,

04:20

you can click "calculate" and it will give you the resultant value necessary to accommodate that stack of tolerances.

04:29

This is a really quick way to do a preview before you even begin the process of creating your 3D models,

04:36

which of course, you'll want to double check with tolerance analysis,

04:39

and share that information with others by generating reports and exporting the information.
