Exact coordinates may not always be available, but accuracy is imperative. Making sure geometry is placed correctly is easy when referencing existing geometry and utilizing Object Snaps.
Object Snaps: Allows the user to select an exact locations on existing geometry without knowing specific coordinates. When the prompt is for a “point” Objects Snaps are accessed individually by either typing in the complete Object Snap name. For a quicker approach, type in the first three letters of the Object Snaps name (1) (not case sensitive) or hold down the Shift Key then Right-Click (2) also if you Right-Click without the Shift key you will receive a pop up window- select Snap Overrides for the Object Snaps pop-up window. (3)
(1) end = Endpoint tan = Tangent
mid = Midpoint per = Perpendicular
int = Intersection par = Parallel
app = Apparent Intersection nod = Node
ext = Extension ins = Insert
cen = Center nea = Nearest
qua = Quadrant none = None
Snap tab. Selected Object Snaps are active (available) all the time and ready to use when the prompt is for a “point”. To access the Drafting Settings dialog box through the command line type in DSETTINGS then enter, or Right-Clicking over the Icons on the left side of the Status Bar, this activates a pop up window – select Settings (4). Hint: Right –Click over the icon you want and it will open the Drafting Setting dialog box to that specific tab. (Example place the cursor over the Object Snap icon, Right-click, the Drafting Settings dialog box opens and the Object Snap tab is current).
Snap Override: This feature is used when you need an Object Snap that is not Running for a one time selection. This puts a temporary hold on the preset Running Object Snaps. They are accessed by the above examples (1, 2 and/or 3) while in a command that prompts for a point.
* Object Snaps are saved within the program not within a drawing, they stay set until changed.
* Time saver: To toggle the Running Object Snaps, ON or OFF, select the F3 key or select the
Object Snap Icon located in the Status Bar.
* Accessing the Drafting Setting dialog box repeatedly, to modify the Object Snap options, results as a time consuming event. Suggestion: preset your most used Object Snaps (three to five) as Running Object Snaps, then, incorporate Snap Overrides when needed. Using both approaches will lead to a smoother flow when drawing and improve your drawing time.
