To perform a trim, follow these steps:

1. Select the Trim tool ().
   Tip: Until you hover over a solid group or component, you see an arrow cursor with a circle and a slash. When your cursor hovers over a solid group or component, the red circle and slash change to a black 1 inside a circle, and you see a Solid Group or Solid Component ScreenTip.
2. Click to select the cutting group or component. In the example shown here, select the peg first to make a hole in the board. After you make a selection, the 1 next to the cursor becomes a 2.
3. Click the group or component that you want to cut. The cutting group remains, but makes a hole in the second selection. The result is hard to see at first (refer to Callout 1). However, move the peg out of the hole, as shown in Callout 2, and you see the hole in the board.

to perform an intersection, follow these steps:

1. select the intersect tool ().
   tip: until you hover over a solid group or component, you see an arrow cursor with a circle and a slash (). when your cursor hovers over a solid group or component, the red circle and slash change to a black 1 inside a circle, and you see a solid group or solid component screentip.
2. select a solid entity that you want to use in the intersection.
3. select one or more additional solids that overlap your initial selection. the resulting intersecting geometry remains. in this example, the intersection of the box and the sphere (callout 1) creates a point with a rounded base (callout 2).

tip: alternatively, you can preselect the solids you want to intersect. the context-click your selection and choose solid tools > intersect from the menu that appears.

automatically fixable errors

several errors that solid inspector detects can be fixed automatically. solid inspector errors are identified by red-highlighted geometry, so that you can take a closer look before giving solid inspector the ‘okay' to automatically fix errors. automatically fixable errors include:

• reversed faces: solid inspector is also a handy utility for making sure that face normals are facing outwards.
• stray edges: surplus edge geometry that does not define any face.
• internal and external faces: stray geometry on the inside or outside of your model.
• face holes: a hole in an exterior face. easy fix for solid inspector.

manually fixable errors

some errors cannot be automatically fixed by solid inspector, and must be manually repaired using sketchup's drawing (or eraser) tools. after fixing a few manual errors, it's a good idea to re-run the inspector to see if your changes have cleaned up the model enough for automatic fixing to take over. manually fixable errors include:

• border holes: these holes share at least one edge with the surface of a solid. these errors can be manually fixed by drawing over or erasing the highlighted geometry. as you go, try re-running the inspector to see if you've done enough repair go for solid inspector to automatically fix the rest of the model.
• nested groups/components: nested objects in groups or components can lead to confusing stl exports for 3d printers. solid inspector won't fix these manually, but you can use the inspector to look at each nested instance and decide whether to delete it or explode the geometry into your model.
• image entities: images imported into sketchup can't be exported to an stl file and also inhibit solid tool operations. solid inspector will prompt you about these errors, but you'll need to delete them manually. consider making image entities into components. they are easy to temporarily delete from your model in this respect. also, painting a face with an image texture doesn't impact solid-ness.
• short edges: very small geometry can cause problems in 3d prints or solid operations. since these problems are unpredictable -- and short edges do not disqualify objects as solid in sketchup -- solid inspector will not fix these errors automatically. however, solid inspector is a great way to find and evaluate these problem areas.

show errors

when you have multiple errors that cannot be fixed automatically, it's useful to use the 'show errors' command to navigate between individual problems that you'll need to manually fix. use the left and right arrows to cycle through all the errors of a certain type that solid inspector has identified; the sketchup camera will zoom to the problem area.

With SketchUp Pro's Intersect tool (), you select two or more overlapping solid entities, and only the intersecting geometry is left behind.

To perform an intersection, follow these steps:

1. Select the Intersect tool ().

3. Select one or more additional solids that overlap your initial selection. The resulting intersecting geometry remains. In this example, the intersection of the box and the sphere (Callout 1) creates a point with a rounded base (Callout 2).
