This type of arrangement can be obtained by creating an array of objects. You may need to create an object multiple times in a rectangular or circular arrangement in some cases. The Move Tool is used to move one or more objects from their current location to a new location without changing their size or orientation. You can use the Offset tool to draw parallel lines, polylines, concentric circles, arcs, curves, etc., While offsetting an object, you need to specify the offset distance and the side to offset. You can either continue selecting the objects or press ENTER to terminate the object selection process and erase the selected objects. To erase the object, select it by using the pick box the selected object will be displayed in dashed lines, and the Select objects prompt will be displayed again. A small box, known as a pick box, replaces the screen cursor on invoking the Erase tool. To invoke the Modify toolbar, choose View>Windows>Toolbars>AutoCAD>Modify from the ribbon. To erase an object, choose Erase tool from the Modify panel. Sometimes, you need to erase the unwanted objects from the objects drawn. The Rotate tool can also be invoked from the shortcut menu by selecting an object and right-clicking in the drawing area, and choosing Rotate from the shortcut menu. By default, a positive angle results in counterclockwise rotation, whereas a negative angle results in a clockwise rotation. On invoking this tool, you will be prompted to select the objects and the base point about which the selected objects will be rotated. A mirror line is an imaginary line about which the objects are mirrored. On selecting objects to be mirrored, you will be prompted to enter the first point of the mirror line and the second point of the mirror line. On invoking this tool, you will be prompted to select objects. This tool is helpful in drawing symmetrical figures. The objects can be mirrored at any angle. This tool is used to create a mirror copy of the selected objects. You can continue specifying the second point for creating multiple copies of the selected entities. Next, you need to specify the second point where the copied objects have to be placed. On invoking this tool, you need to select the objects and then specify the base point. This tool is used to make the copies of the selected objects and place them at the specified location. You can use this option whenever you want to extend the objects that do not actually intersect the boundary edge but would intersect its edge if the boundary edges were extended. You can extend lines, polylines, rays, and arcs to meet the other objects using the Extend tool. The Extend tool may be considered as the opposite of the Trim tool. After the cutting edge/edges are selected, you must select each object to be trimmed. These edges can be lines, polylines, circles, arcs, ellipses, rays, splines, text, blocks, xlines or even viewports. On invoking the Trim tool, you will be prompted to select the cutting edges. In such cases, you can use the Trim tool. When creating a design, you may need to remove the unwanted and extending edge. Specify next point or : specify the endpoint of the second polyline segment or press ENTER to exit the command. Specify next point or : specify the endpoint of the first polyline segment. Specify start point: specify the starting point or enter its coordinates After invoking the PLINE command and specifying the start point, the following prompt is displayed: To draw a polyline, you need to invoke the PLINE command. You can draw rectangles by specifying two opposite corners of the rectangle, specifying the area and the size of one of the sides, or specifying the rectangle’s dimensions. You can draw a circle by using six different tools, i.e., by specifying center and radius, by specifying center and diameter, by specifying two diametrical ends, by specifying three points on a circle, tangent to two objects, tangent to three objects. CircleĪ circle is drawn by using the CIRCLE command. You can terminate the LINE command by pressing ENTER, ESC or SPACEBAR. You will have to specify the starting point of the line by clicking the mouse then you will be prompted to specify the second point. You can invoke the LINE command by choosing the LINE tool from the Draw panel, or you can also invoke the LINE tool by entering LINE or L at the Command Prompt. 3D animation, modelling, simulation, game development & others 1.
