Graphics Programs Reference
In-Depth Information
Insert (ins)
Selects the insertion point of text, blocks, Xrefs (see Chapters 4 and 7), and
overlays.
Intersection (int)
Selects the intersection of objects.
Mid Between 2 Points (m2p)
Selects a point that is midway between two other points.
Midpoint (mid)
Selects the midpoint of a line or an arc. In the case of a polyline, it selects
the midpoint of the polyline segment.
Nearest (nea)
Selects a point on an object nearest the pick point.
Node (nod)
Selects a point object.
None (non)
Temporarily turns off Running Osnaps for a single point selection.
Parallel (par)
Lets you draw a line segment that is parallel to another existing line seg-
ment. To use this option, type
PAR
↵ during point selection, or select Parallel from the Osnap
pop-up menu. Then move the cursor to the line you want to be parallel to and hold it there
until you see a small, cross-shaped marker on the line. The cursor also displays a tool tip with
the word
parallel
, letting you know that the Parallel osnap is active.
Perpendicular (per)
Selects a position on an object that is perpendicular to the last point
selected.
Point filters
Not really object snaps, but point-selection options that let you filter X, Y, or Z
coordinate values from a selected point. (See Chapter 19, “Creating 3D Drawings,” for more
on point filters.)
Quadrant (qua)
Selects the nearest cardinal (north, south, east, or west) point on an arc or
a circle.
Tangent (tan)
Selects a point on an arc or a circle that represents the tangent from the last
point selected.
Temporary Track Point
Provides an alternate method for using the Object Snap Tracking
feature described later in this chapter.
Sometimes you'll want one or more of these osnap options available as the default selection.
Remember that you can set Running Osnaps to be on at all times. Type
DS
↵, and then click the
Object Snap tab. You can also right-click the Object Snap tool in the status bar and choose Settings
from the shortcut menu to open the Drafting Settings dialog box, or just select osnap options directly
from the shortcut menu.
Erasing the Layout Lines
Next, you'll erase the layout lines you created using the Offset command. But this time, you'll
try selecting the lines
before
issuing the Erase command.
Follow these steps:
1.
Click each internal layout line individually.
If you have problems selecting just the lines, try using a selection window to select single
lines. (Remember, a window selects only objects that are completely within it.)
