Position snapping and angle snapping are powerful helpers that allow you to achieve greater accuracy when designing and editing objects. When an object or a point “snaps,” it is positioning itself at a point of interest, such as a grid intersection or the edge of another shape on your design.
To edit snap settings:
1. From the Settings menu, click Snap Settings. Or press G.
2. Modify the settings as needed and then click OK.
Enable snaps
Enable all position-based
snapping.
Grid
Enable grid snapping. When grid snapping is
enabled, objects and points will snap to the grid intersections.
Point
Enable point snapping. When point snapping
is enabled, objects and points will snap to the points of nearby
shapes.
Edge
Enable edge snapping. When edge snapping is
enabled, objects and points will snap to the edges of nearby shapes.
Midpoint
Enable midpoint snapping. When midpoint
snapping is enabled, objects and points will snap to the midpoints of nearby
shape edges.
Center
Enable center snapping. When center
snapping is enabled, objects and points will snap to the center of nearby
shapes.
Tangent
Enable tangent snapping. When adding a
new shape, if the first point is placed on a curve, then the second point will
snap to the line which is tangent to that edge.
Extension
Enable extension snapping. When adding
a new shape, if the first point is placed on the endpoint of a line, then the
second point will snap to a line parallel to the starting line.
Perpendicular
Enable perpendicular snapping. When
adding a new shape, if the first point is placed on the edge of an existing
shape, then the second point will snap to a direction perpendicular to that
edge.
Show tooltips
Enable snap tooltips. When tooltips
are enabled, a small information box will explain what is currently being
snapped to.
Show drawing aids
Show additional information
about what is currently being snapped to. For example, when snapping to an
extension a dashed line will appear showing where the extension originates
from.
Snap tolerance
Distance, in pixels, at which your
mouse cursor will snap to the target. Because distance is measured in pixels,
the snapping tolerance will intuitively adjust to your zoom level and monitor
size.
Enable Angle Snap
Enable angle snaps. When angle
snaps are enabled, objects will snap to the Snap angle when they are
rotated.
Snap angle
What angles objects will snap to when
they are rotated.
Show grid
Enable visibility of the grid. The
grid does not need to be visible for objects to snap to it.
Disable grid snap when hidden
Disable grid
snapping when the grid is hidden. This option is more intuitive for new
users.
Follow terrain topology in Perspective view
Project the grid over the terrain, following its changes in elevation.
Uncheck this option for a flat grid.
Grid size
Size of each grid square in feet or
meters.
Major line every
Rate at which darker grid lines
appear. For example, if the Grid size is set to 1 foot, and this setting is 10,
then a dark grid line will appear every 10 feet.
Grid color
Current color of the grid.
Tips:
• Press G to access the snap settings dialog.
• All position snapping can be quickly enabled or disabled by clicking the Toggle Snaps button found to the left of the screen, or by pressing Ctrl+G.
• The visibility of the grid can be quickly enabled or disabled by clicking the Toggle Grid button found to the left of the screen, or by pressing Ctrl+I.
• Angle snapping can be quickly enabled or disabled by pressing Ctrl+A.
