VIEWDETAIL command
Draws view details of drawing views made with the VIEWBASE command.
                Icon: 
- This command operates only in Paper Space.
 - When the GENERATEASSOCVIEWS (Generate associative drawings) system variable is ON, associative dimensions for detailed views are updated automatically when the 3D model is modified.
 - DRAWINGVIEWQUALITY variable defines the quality of drawing views.
 - The AUTOVPFITTING variable controls whether the size of the viewport is adjusted automatically to fit the current extents of the 3D geometry. By default AUTOVPFITTING = ON.
 
Method
Select the drawing view from which to extract the detail by clicking inside a drawing view. The program highlights the selected view.
After that, specify the center point of the detail view by picking a point inside the parent view and the style of the view boundary.
There are two boundary types from which you can choose:
- Circular - draws a circular boundary.
 - Rectangular - draws a rectangular boundary.
 
Specify the position for detail view by picking a point in the layout, away from the parent view.
Options within the command
- Scale
 - Specifies the scale of the detail view, which by default is twice the parent viewport scale:
 
- Standard scales
 - Choose a standard scale in the list; the list can be edited by the SCALELISTEDIT command.
 
- Custom
 - Specify a custom scale factor.
 
- Relative custom scale
 - Calculates the scale factor relative to parent view by multiplying the scale factor of the source view with this number.
 
- from Parent
 - Sets the scale of the section view equal to the scale of the parent view.
 
- Hidden lines
 - Control the visibility of hidden lines, or uses the same hidden lines setting as the parent view.
 
- Tangent lines
 - 
                            
Controls the display of tangent edges which appear in the transition from a flat face and a curved face, such as with fillets:
Note: When the BM_Tangent_Visible layer is off or frozen, tangent lines are not display. 
- anChor
 - Determines if the center of the viewport is anchored so that the viewport grows and shrinks around its center point or not.
 
- Geometry
 - Selects the visual style for the section view:
 
- 2D
 - Section view uses the 2dWireframe visual style.
 
- 3D
 - Section view uses a rendered visual style. This is Conceptual by default. Use the Properties panel to choose a different visual style.
 
- Annotation
 - Determines the annotations to use.
 
- Identifier
 - Specifies the view detail identifier by entering a name for the view detail.
 
- Label
 - Toggles the display of the view detail label.
 
- Boundary
 - Toggles the style the boundary between circular and rectangular.
 
- Circular
 - Changes the boundary to a circle.
 
- Rectangular
 - Changes the boundary to a rectangle.
 
- modeL edge
 - Controls whether a connection line is drawn between the detail view and the detail boundary in the parent view.
 
- smooth with Border
 - Does not draw a line.
 
- smooth with Connection line
 - Draws a connecting line from the detail view to the parent view.
 
Grips Editing
Detail views can be edited through grips: select the view and six grips display:
                - Controls the position of the identifier.
 - Controls the position of the section detail.
 - 4 grips control the size of the detail boundary.
