Use the 
  Display Properties dialog to control the display of the solid components of the machine during full machine simulation: 
To open this dialog, select Machine Design tab > Options panel > Display Properties. 
To use this dialog: 
- Select or pick the solid. 
  
 
- Enter the 
	 Fineness value. (Low numbers look better, but may slow down the simulation. High numbers run faster, but the solid may appear faceted.)
