A polyline (PLINE) is a single object with connected sequence of line segments or and arc segments. You can set the global width of polyline and the starting and ending width for each segments. When you draw a polyline, you can switch to arc by... Read More

You can use the LINE command to generate one or a series of continuous line segments. Each segment is a separate line object, you can assign properties such as COLOR , LINETYPE and lineweight (LWEIGHT) to each line. If you want to connect the... Read More

Calculate distances and angles You can get information about the relation between two points by inquiring distance. You can get information as following: Distance = 1525.7461, Angle in XY Plane = 29, Angle from XY Plane = 0Delta X = 1332.6216, Delta... Read More

To improve drawing efficiency, you can display a rectangular grid and snap it. You can also control its spacing, type and behavior. The grid helps you align objects and determine the distances between them. When SNAP mode is on, the movement of the... Read More

If you open the ORTHOMODE  , cursor movement is restricted to horizontal and vertical, then you can create and modify drawings more accurately and conveniently. You can turn the Ortho mode on or off by Ortho button on the status bar or press F8 key... Read More

Polar tracking is used to display temporary alignment paths defined by the polar angles you specify, while you are creating or modifying objects. You can set the angle base (ANGBASE)direction in the Drawing Units dialog box. Alignment paths and... Read More

Without having to know the exact coordinates, object snaps enable you to quickly locate points relative to existing objects such as center points of circles or midpoints of lines. Use Running Object Snaps Press F3 or click the OSNAP button on the... Read More

Define user coordinate systems You can apply a user coordinate system (UCS ) with its own 0,0,0 origin and orientation in three-dimensional spaces. To simplify construction of three-dimensional entities, you can create as many user coordinate... Read More

When you create objects in 3D, Cartesian, cylindrical or spherical coordinates are used to locate points. Enter X.Y.Z coordinates 3D Cartesian coordinates determine a precise location by using three coordinate values: X, Y, and Z. Entering 3D... Read More

Enter absolute coordinate Absolute coordinates are based on the UCS origin (0,0), which is the intersection of the X and Y axis. If you know the precise X and Y values of the point, you can use absolute coordinates. Enter relative coordinate The... Read More
