“Snap” Tab
Customizing System
This tab serves to define parameters that are used when working in the object snapping mode (including the
cases of sketch creation).
Search radius. Sets the radius in pixels for searching the
elements of the system on the screen. This parameter
is used in new element creation in object-snapping
mode. Keep in mind that this parameter setting
overrides the “Node join distance” parameter defined
on the “Preferences” tab.
Select Graphic Lines when creating hatch contours
instead of Construction Lines. Setting this parameter
allows selecting graphic lines when constructing
hatches and 2D paths. This is required in the cases
when the construction lines coincide with graphic
lines. This option helps set up object snapping so as to
have the desired elements selectable in the
complicated cases upon the cursor approaching,– for
example, graphic lines (if the parameter is set). At the
same time, it is still possible to select other elements
by using the keyboard commands ( – select a
circle, – select a line, etc.).
Show Tooltips. Sets the pop-up tooltip display mode
when selecting elements on the drawing while in
object-snapping mode.
Enable Snap to Nodes on Frozen Layers. If this flag is turned off, snapping to nodes, located on “frozen”
layers is not possible. Upon turning on this flag, snapping to such nodes becomes possible.
The group of flags “Enable Snaps to:” determines, what snap types can be used in the object snapping
mode.
Most snaps can be managed even outside the command “SO: Set System Options” – by using
icons on the “Snaps” toolbar.
For example, suppose, a tolerance needs to be placed next to a dimension. To achieve that, enable the flag
“Enable snaps to/Dimensions”. Call the command “Draw|Tolerance”. As the cursor approaches a
dimension defining point, it becomes marked with a rectangle. If you then click , a node will be created,
and an annotation element – tolerance will be created.
To snap a tolerance to the midpoint of a graphic line, enable the flag “Enable snaps to/Graphic Line
Middle Points”. In this case, while in the tolerance creation command, midpoints of graphic lines will be
