- Accelerated 
				 drawing of fast draft views: Allows you to hide 
				 the image of the view and not to recalculate except for 
				 zooming. Certain maps do not support this mode, in this 
				 case, uncheck the option. 
- Optimize 
				 edge drawing for thin shapes: Allows display defects 
				 of graphics cards to be corrected for the hidden edges 
				 of thin parts 
- Accelerated 
				 drawing of transparency: The transparency quality 
				 is slightly deteriorated during dynamic displacements 
				 to increase display performance. 
- Draw 
				 edges of draft with thin width: Allows to display 
				 all lines of the draft with thin width. Of course, when 
				 printing, lines will have the correct width. 
- Draw 
				 silhouettes in wireframe render modes: When a cylinder 
				 in perspective is in wireframe render, it is displayed 
				 with only 2 circles. This option allows to also display 
				 the 2 lines. Turning on this option decreases graphic 
				 performances. 
- Transparent 
				 shapes hide edges: In this case, transparent shape 
				 is considered as opaque. 
- Highlight 
				 detected faces: Detected faces are framed as during 
				 selection, but also colored. 
- Highlight 
				 selection of parts in tree: Display a wired echo 
				 of the hidden geometries when making a selection or zooming 
				 from a tree (Entities, Parts...). 
- Display 
				 scale bar: Allows you to display the scale bar 
				 in the bottom right-hand side of the screen.
