The Drawing parameters dialog
box groups all settings specific to the current file.
This can be a DWG file or a schematic drawing.

Object snap-on modes
Activate object snap-on: Activates
or deactivates the use of specific points. You can also click OSNAP
on the status bar or press F11.
Each graphical entity has specific points that can be used to edit or
to place other entities. For example, a line has two endpoints and a midpoint,
a circle has its center and four quadrant points.
The green icon represents the marker form of each mode.
Endpoint: Snaps to the endpoint
of a Line, Arc or other entity. The mode does not differentiate between
the start or endpoint of the entity.
Middle point: Snaps to the midpoint
of a Line or an Arc.
Center: Snaps to the center
of a Circle, Ellipse, or Arc.
Node: Snaps to a point entity,
dimension definition point, or Dimension text origin.
Quadrant: Snaps to the nearest
quadrant of a Circle or Arc. Quadrants refer to the points of a Circle
or Arc on the circumference at 0°, 90°, 180°, and 270°. These are the
intersecting points of the axes of a coordinate system upon whose origin
lies at the center of the Circle or Arc with the circumference of the
Circle or Arc. Only the next visible quadrant of an Arc can be snapped.
Insert: Snaps to the insertion
point of a Block insertion, an attribute, or a Text entity.
Perpendicular: Requires that
a start point has been selected. Activating the Snap mode relates this
point to the snapped point. For instance, select the endpoint for the
perpendicular. the Perpendicular mode is activated. The
result is a perpendicular Line from the endpoint to the selected entity.
Tangent: Requires that a start
point has been selected. Activating the Snap mode relates this point to
the snapped point. For instance, to create a Line tangent to a Circle,
select the endpoint for the tangent Line; the Tangent
mode is activated. The result is a tangent Line from the endpoint to the
chosen entity.
Nearest: Snaps to the next situated
point of an entity when at least one point of the entity lies within the
borders of the cursor. If you select a point without using Nearest
mode, the selected point might not be on the desired entity. This mode
ensures that the entities share a point with the specified entity.
Intersection: Snaps to the intersection
points of Lines, Arcs, and Circles, or any combination of them.
Drawing
You can turn parameters such as Ortho
and Grid on
or off by clicking them in the
status bar or using keyboard shortcuts.
Snap On (F9): Locks the cursor
on the Snap spacing parameter,
as a virtual grid. This option must not be confused with the grid
settings.
Grid On (F7): Shows or hides
the grid in the drawing.
Ortho On (F8): Turns the ortho
trap on or off; this fixes pointer movement on the X or Y axis.
Line Weight Active (F10): Turns
the line weight on or off; this shows or hides the various line thicknesses.
Show wipeout frames: Shows or
hides the wipeout outlines.
Snap spacing: Defines the space
between two virtual snap points.
Grid spacing: Defines the space
between two grid points.
Line type scale: Lets you modify
the line aspect based on the units used in the current file. Only complex
line types (such as axes and discontinuous) are impacted by this parameter.
A scale factor is used on them to enlarge or reduce spaces and lines.
Measurement system: Allows to
defines the unit system for measurement.
Grid zone: Defines the coordinates
of the zone in which the grid is displayed. You can also click the button
to graphically define this zone.
