# Tutorial: Simplifying Geometry

Learn how to find and remove pockets, holes, rounds, and fillets.

In this lesson you will learn how to:
• Find and remove pockets and holes
• Find and remove rounds and fillets
• Push and pull faces

The Simplify tools on the Geometry ribbon can be used to remove features that normally prevent easy modification of a design space used for optimization. This tutorial will illustrate how to modify your design space by removing pockets, rounds, and fillets.

## Open the Geometry Simplification Model

1. Press F7 to open the Demo Browser.
2. Double-click the Geometry Simplification.x_t file to load it in the modeling window.
3. Adjust the view so the model is positioned as shown below:
4. Make sure the display units in the Unit System Selector are set to MPA (mm t N s).

## Remove Holes and Pockets

1. Open the Holes tool:
Tip: To find and open a tool, press Ctrl+F. For more information, see Find and Search for Tools.
1. Select the Simplify tool on the Geometry ribbon.

2. Select the Holes tool from the secondary ribbon.

Inspire automatically finds all of the holes and pockets in your model, which are shown in red. The number shown above the Holes icon indicates the total number of holes and pockets found, in this case twelve.
2. Mouse over one of the pockets.
You'll notice the mouse cursor changes and shows a check mark.
3. Left-click the pocket to remove it.
4. Continue removing the other five pockets (there are three on each side) by left-clicking on them.
Note: Do not remove the holes.
5. Right-click and mouse through the check mark to exit, or double-right-click.

## Find Rounds and Fillets

1. Open Rounds tool:
Tip: To find and open a tool, press Ctrl+F. For more information, see Find and Search for Tools.
1. Select the Simplify tool on the Geometry ribbon.

2. Select the Rounds tool from the secondary ribbon.

Inspire automatically finds all of the rounds and fillets in your model. The number shown above the Rounds icon indicates the number of fillet chains (as opposed to individual fillets) found.
Note: When possible, fillets should be removed in chains rather than individually.
2. You'll notice the default search value may automatically find more fillets and rounds than you want. Click the button on the guide bar and select Find Options.
3. Change the upper bound for the Radius from 32.5 mm to 5 mm and press Enter.
This will filter the search results so that only fillets and rounds with a radius of 0 mm to 5 mm are selected.
4. With the filter applied, the number of round and fillet chains detected drops to 6.

## Remove Rounds and Fillets

1. Click the Remove All button to remove all fillets and rounds.
You'll notice not all fillets have been removed. Due to construction history, chains of fillets and rounds are removed in the same order they were created.
2. Click the Find button in the guide bar. Notice the number of rounds is now 3.
3. Zoom in on the single fillet that appears in the top left corner of the model.
Note: You can select, deselect, and remove individual rounds or chains of rounds in the following ways:
• Click on a round or fillet to select it.
• If there are several contiguous rounds or fillets, double-click one to select the entire chain. Selecting an adjacent round/fillet will add to the chain.
• Click on a selected round or fillet again to remove it. If it is a part of a chain, the entire chain will be removed.
• Hold down the Ctrl key and left-click to deselect a round or fillet. Hold down the Ctrl key and double-click to deselect an entire chain.
4. Click the Remove All button again.
Now the rounds and fillets are completely removed.
5. Right-click and mouse through the check mark to exit, or double-right-click.

## Push/Pull Interior Faces

1. With the rounds and fillets removed, it is possible to push and pull the interior faces. Select the Push/Pull tool on the Geometry ribbon.
Tip: To find and open a tool, press Ctrl+F. For more information, see Find and Search for Tools.
2. Left-click once on the face shown below:
3. Click and drag the pyramid to position it on the exterior face.
This will redefine the starting point of the push/pull operation.
4. Type 12 in the microdialog and press Enter.
5. Repeat the push/pull procedure for the other interior face, pulling it to 12 mm.
6. Right-click and mouse through the check mark to exit, or double-right-click.
