autocad的绘图技巧(八)（AutoCAD drawing skills (eight)） The drawing skills of AutoCAD (eight) Release date: 2008-6-11 collection comments have to [knowledge] Polygon AutoCAD can create the number of edges is 3 to 1024 equilateral polygon drawing, can choose inscribed or circumscribed style elements Type, generally we completed by direct numerical input or select endpoint side way. In fact, we can also draw a polygon through two specify endpoint of an edge, which is especially suitable for the part has been drawn graphics case, which use the Polygon command in the Edge parameter, when we click on the polygon button or enter Polygon command. First need to input a number of polygon edges, the next step is to select the Edge parameter, and then capture the two endpoints can complete the polygon, which can greatly reduce the time of drawing. Use parallel command Offset (parallel) command to the specified object translation distance, creating a new object similar to the original object, it can operate primitives including straight line, circle, line, polyline, construct the spline curve, when translating a circle, it can also create a concentric circle; when translation a closed polyline, also can build a closed figure the same shape with the original object, because of this, the Offset command is a command of the highest frequency of use AutoCAD editing commands. In the use of Offset, the user can create a new line through two ways, one is to enter the distance between the parallel lines; the other one is to specify a new parallel line through the point, select the parameter Through, to capture a point as a new parallel line through the point, instead of parallel input line distance, not easy to make a mistake. Special symbol input We know that the diameter of the diameter, said the plane +, degree of mark symbols can be used to control the%%c,%%p,%%d code to enter, but if you want to do other input symbols? We can use the character map to the input of special characters: 1, ent
