Creating a Breakout View in Autodesk Inventor

“A dream is your creative vision for your life in the future. You must break out of your current comfort zone and become comfortable with the unfamiliar and the unknown.”
Denis Waitley

When I training Autodesk Inventor, I always take a little bit of extra time on the break out view in drawings.  It's a great way of showing details for internal parts inside an assembly, and not difficult to create in Inventor.

 But when creating a break out view, it's got one place that usually snags everyone as the first few times they use it.  I know it got me when I first started it.

 That step is, associating the sketch to the view.  If the sketch isn't associated to the view, the break out view won't work, and the breakout command will error out.

This is the error seen when the sketch isn't associated
So how is the sketch associated?  What is it that's so special?

I'll talk about all the steps, and specify that special step to create the sketch association.

1. Click on the view that the breakout view will be placed on. The border will highlight, indicating it's selection.  This is the critical step that will create the associated sketch!

Make sure to select the view before creating the sketch!

2. Now, click the "Create Sketch" icon.  The sketch is created, and it's axes will center on the view.  It's this centering of the axes that tells us the sketch has associated to the view.

3.  Now sketch a closed figure around the area to break out. It can be any shape, it just has to be closed.  Here I use a spline. Finish the sketch when done.

4. Now click on the "Break Out" icon.   Select the sketch with the view.

5. Define the options for the break out.  One helpful tip is to point out that projected views can be used to help with the definition, not just the view that will host the breakout.  In the image below, I've used a projected view to define the break out depth.

6. Choose okay and the breakout view is created.

 I could say "That's All Folks", but instead, here's a couple of other tips that I find helpful.

There will be times that not every component in the break out view is supposed to be sectioned, as step 6 shows above.  Here's how to change that.

The first is to locate the part in the feature browser, right click on it, locate "Section Participation", and changed it's setting to "None".

The other is to hold down the "Shift" key with nothing selected, and right click.  Choose "Part Priority" from the menu.

Now select the part on screen, right click, and the same options for "Section Participation" are available.

Which ever means you prefer, the sectioning for selected components can be turned off, if desired.

On a last tip, I've shown what happens when the selections are correct, but how can you tell when the view isn't associated, so a mistake can be quickly corrected before the error on view creation appears? 

There are two quick ways to tell.

1. If the sketch is created, but the axes aren't centered on the view, the sketch isn't associated.

2. If the "Project Geometry" icon is grayed out, then the sketch isn't associated.  This is because Inventor doesn't see any geometry to project.  If the sketch is associated it will.

 In conclusion, I hope this helps a few of you out in the "Verse" with break out view.  It's a great tool, and can be a great way to add informative detail on a drawing.
