Step 2ĭraw another line between the midpoint of the other opposite sides of the rectangle or square. Method 1 Method 2 Step 1ĭraw a line between the midpoints of two opposite sides of the rectangle or square. The circle is located exactly in the center of the square or rectangle. In this step, a circle is inserted at the midpoint of the line. The midpoint of the construction line that you inserted in Step 1 is the center of the square or rectangle. Method 1 Step 1ĭraw a construction line between any two diagonal corners by snapping to the endpoints. To do this, either one of the following methods can be used. Using geometry, the center of a square or a rectangle can easily and accurately be located without knowing its size or doing any math. Figure 8-4 Geometry Lesson: Finding the Center of a Square or Rectangle Note that the Graphic cursor does not have to be located exactly at the endpoint of the line. In Figure 8-4, AutoSnap is indicating that it found the endpoint of the line. While a command is active, AutoSnap displays a markerand a tool tip when the cursor is moved over an object snap mode location that it has been set to find. Object snap can be enabled or disabled anytime by pressing F3. It allows you to set the object snap modes that AutoSnap will find automatically when object snap is enabled. Figure 8-1 Object Snap Modes for a Circle Figure 8-2 Object Snap Modes for a Line Figure 8-3 Object Snap Modes for an Arc AutoSnapĪutoSnap is a visual aid to help you see and use object snap modes (locations) more efficiently. When requested, AutoCAD can find and snap to these exact locations. A line has 3 snap mode locations that can be snapped to while circles and arcs have 5 each.
They show the object snap modes and their locations for a line, a circle, and an arc. Object snap is one of the most important features in any CAD system. This is done without having to know the coordinate locations of those objects. Using object snap allows you to draw quickly and accurately using the existing geometry in the drawing. Many more will be taught throughout the AutoCAD 2D book. In this module, the object snap modes for the drawing objects line, circle, and arc are taught. All drawing objects have at least one object snap mode. Object snapallows you to immediately locate and attach to predefined object snap modes (locations) on existing drawing objects.
