Follow the steps below to edit or cut objects such as bars or contours along a cutting plane. 
To access the Cut by Plane dialog, click Edit 
 
Cut by plane. 
To divide the edges of an object
- In the Cut by Plane dialog, select Divide contour edges. 
 
- Specify the Cutting plane definition in either of the following ways: 
- Select an axis: XY, YZ, or ZX, and then select a point of origin for your cutting plane. 
 
- Select arbitrary, and then select three points on the model to specify a customized cutting plane. 
Note: Alternatively, enter the coordinates of the three points in the Point 1, Point 2, and point 3 boxes. 
  
  
-  In the Objects to be cut box, enter the identification number of the objects that you want to cut, or select them in the drawing area. 
 
- Click Apply, and then click Close. 
 
 
To create nodes where an object and the cutting plane intersect
- In the Cut by Plane dialog, select Create nodes at intersections. 
 
- Specify the Cutting plane definition in either of the following ways: 
- Select an axis: XY, YZ, or ZX, and then select a point of origin for your cutting plane. 
 
- Select arbitrary, and then select three points on the model to specify a customized cutting plane. 
Note: Alternatively, enter the coordinates of the three points in the Point 1, Point 2, and point 3 boxes. 
  
  
-  In the Objects to be cut box, enter the identification number of the objects that you want to cut, or select them in the drawing area. 
 
- Click Apply, and then click Close. 
 
 
To split all the objects that intersect with the cutting plane
- In the Cut by Plane dialog, select Split objects. 
 
- Specify the Cutting plane definition in either of the following ways: 
- Select an axis: XY, YZ, or ZX, and then select a point of origin for your cutting plane. 
 
- Select arbitrary, and then select three points on the model to specify a customized cutting plane. 
Note: Alternatively, enter the coordinates of the three points in the Point 1, Point 2, and point 3 boxes. 
  
  
-  In the Objects to be cut box, enter the identification number of the objects that you want to cut, or select them in the drawing area. 
 
- Click Apply, and then click Close. 
 
 
To cut off all objects on a specific side of the cutting plane.
- In the Cut by Plane dialog, select Cut off. 
 
- Specify the Cutting plane definition in either of the following ways: 
- Select an axis: XY, YZ, or ZX, and then select a point of origin for your cutting plane. 
 
- Select arbitrary, and then select three points on the model to specify a customized cutting plane. 
Note: Alternatively, enter the coordinates of the three points in the Point 1, Point 2, and point 3 boxes. 
  
  
- When a question mark appears in the drawing area, click on the side of the cutting plane where objects should be deleted. 
Note: Alternatively, specify the side of the cutting plane where you want to delete objects in the Side to Cut off box. 
  
-  In the Objects to be cut box, enter the identification number of the objects that you want to cut, or select them in the drawing area. 
 
- Click Apply, and then click Close.
