1. Open the Section menu. (Click the down-arrow to the right of the section icon on the 3D Document Toolbar.)
2. Click Enable Section.

When a section plane is enabled, by default it is shown as a transparent gray rectangle. You may want to make the plane transparent in order to see the section cut more clearly.

1. Open the Section menu. (Click the down-arrow to the right of the section icon on the 3D Document Toolbar.)Right-click anywhere on the section plane to open the context menu.
2. Click Show Section Planes.

1. Click Show Section Planes again to restore the plane.

When the command is enabled, the related icon on the Section menu is highlighted.

When section a plane is enabled, by default faces and edges are highlighted. (See Options for information about setting default colors.)

1. Open the Section menu. (Click the down-arrow to the right of the section icon on the 3D Document Toolbar.)
2. Click Show Profile Edges or Show Profile Faces. (Edges and faces can be displayed simultaneously.)
3. Click Show Profile Edges or Show Profile Faces again to restore the plane.

When the command is enabled, the related icon on the Section menu is highlighted.

By default, cross-sectioning affects every part of an assembly. However, you can choose to show or hide cross-sectioning for each of the parts and subassemblies in your model.

You must have a cross-section plane enabled before you can enable or disable cross-sectioning for objects in an assembly.

1. In the Assembly pane, right-click the name of the part, subassembly, or assembly for which you would like to disable or enable cross-sectioning. This opens the context menu.
2. Point to Section to see the flyout menu.
3. Click Cut Material. By default, the Cut Material command is checked when cross-sectioning is enabled for the object.

To change the color of profile edges or faces:

1. Open the Section menu on the 3D Document Toolbar. (Click the down-arrow to the right of the section icon on the 3D Document Toolbar.)

3. Click the Profile Edges Color or Profile Faces Color button and select a color.
4. Click Apply to preview. Click OK to save the change.

1. Open the Section menu. (Click the down-arrow to the right of the section icon on the 3D Document Toolbar.)
2. Click Align.
3. Click either XY Plane, XZ Plane, or YZ Plane. The red dots on the model designate available vertices on the model. A cross-hatch appears when the pointer is properly positioned over a vertex point.
4. Click a point on the model to position the plane.

1. Open the Section menu. (Click the down-arrow to the right of the section icon on the 3D Document Toolbar.)
2. Point to Place By.
3. Click 3 Points. The red dots on the model designate available points on the model. A cross-hatch appears when the pointer is properly positioned over a point.
4. Click three points on the model to position the plane.

Points may not be collinear.

1. Open the Section menu. (Click the down-arrow to the right of the section icon on the 3D Document Toolbar.)
2. Point to Place By.
3. Click 2 Points. The red dots on the model designate available points on the model.
4. Click two points on the model to position the plane.

1. Open the Section menu. (Click the down-arrow to the right of the section icon on the 3D Document Toolbar.)
2. Point to Place By.
3. Click 2 Screen Points.
4. Click two points in the viewport to position the plane.

Move the section plane

1. Open the Section menu. (Click the down-arrow to the right of the section icon on the 3D Document Toolbar.)
2. Click Define...
3. Select the Movement tab on the Define Section dialog box.
4. In the Step field, enter the number of units you would like the plane to move each time a direction button (<< and >>) is clicked.
5. Use the << and >> buttons to move the plane.
6. Click Apply to see the effect of the movement.
7. Click OK to save the results and close the dialog box.

Rotate the section plane

1. Open the Section menu. (Click the down-arrow to the right of the section icon on the 3D Document Toolbar.)
2. Click Define...
3. Select the Movement tab on the Define Section dialog box.
4. In the Angle field, enter the number of degrees you would like the plane to rotate each time a direction button (<< and >>) is clicked.
5. Use the << and >> buttons to rotate the plane around the Y-Axis and/or the Z-Axis.
6. Click Apply to see the effect of the movement.
7. Click OK to save the results and close the dialog box.

1. To move the section plane along the normal axis - Position your pointer anywhere on the surface of the plane, then click and drag.
2. To move the section plane along the plane axes - Click a handle that is slightly offset from the edge of the plane and drag.

Using the Define Section Dialog Box

From the Define Section dialog box, you can specify the point at which the plane will intersect.

1. Open the Section menu. (Click the down-arrow to the right of the section icon on the 3D Document Toolbar.)
2. Click Define...
3. Select the Position tab on the Define Section dialog box.
   
4. Choose one of the following methods to position a plane:

Pick a point or coordinate system:

• • From the drop-down menu, choose a method for selecting an element. The available methods are:

Pick a Point - Select a point on the model.
Pick a Coordinate System - Select a coordinate system in the scene. The intersection point will be the origin point of the coordinate system frame.

• • Click the Pick button. 
  • Select a point on the model or select a coordinate system. 
  • Click OK to save the position and close the dialog box. 

or

Enter coordinates: 

• • Enter the coordinates of the point in the X, Y, and Z fields. This point is defined with respect to the selected coordinate system—in this case, the Global Coordinate System. 
  • Click Apply to see the effect of the repositioning.
  • Click OK to save the position and close the dialog box.

1. Open the Section menu. (Click the down-arrow to the right of the section icon on the 3D Document Toolbar.)
2. Click Define...
3. Select the Orientation tab on the Define Section dialog box.
   
4. Choose one of the following methods to align the plane:

Pick an element:

• • From the drop-down menu, choose a method for selecting an element. The available methods are:

Pick 2 Points - Select two points on the model.
Pick 3 Points (Normal Plane) - Select three points on the model.
Pick an Edge - Select an edge on the model.
Pick a coordinate system axis - Select a coordinate system axis in the scene. The plane will align along the selected axis.

• • Click the Pick button. 
  • Select points or an edge on the model or select a coordinate system axis. 
  • Click OK to save the position and close the dialog box.

or

Enter coordinates: 

• • Choose an axis by clicking the X-, Y-, or Z-Axis radio button.
  • Enter the coordinates of the point in the x, y, and z fields. This point is defined with respect to the selected coordinate system—in this case, the Global Coordinate System. 
  • Click Apply to see the effect of the alignment.
  • Click OK to save the position and close the dialog box.
