You can use the 
  Tool Load dialog to show a graph of the estimated horsepower load on the tool during 3d simulation. You can use these estimates to fine-tune the program to improve performance. 
Note: The horsepower values are estimates. If you are approaching the power limits of your machine, you should lower your feed rates, or decrease the width or depth of your cuts. 
To show the tool load: 
- Select Home tab > Simulation panel > Show > Tool Load. 
  
- Run a 3D simulation. The 
	 Tool Load dialog displays a graph of the simulation time and the load on the tool. The current simulation time and tool load are displayed below the graph. 
	   
 
- Click 
	 Settings to display the 
	 Power Settings dialog. 
  
- Specify the settings in the 
	 Power Settings dialog: 
	 
- 
Max. Power — This displays the maximum horsepower used so far. Display this dialog at the end of a simulation to see the maximum horsepower used in the entire program. 
		
- 
Power Limit — Enter a maximum horsepower displayed in the 
		  Tool Load dialog. 
		
- 
Pause simulation — Select this option to pause the simulation when the 
		  Power Limit value is exceeded. 
		
- 
Show this dialog — Select this option to display the 
		  Power Settings when the 
		  Power Limit is exceeded. 
		
- 
Clear — This clears the 
		  Max. Power value and clears the graph when the simulation resumes. 
		
 
- Click 
	 OK to close the 
	 Power Settings dialog. 
  
- Repeat the 3D simulation to show the graph using the updated settings. 
  
Note: You can control the accuracy of the graph with the 
  Power graph: samples/min setting on the Options > Simulation > 2D/3D Shaded page. 
If you have run a 
  feed optimization, the 
  Tool Load graph shows the optimized loads in black and the unoptimized loads in white:
