    摘要： A method, apparatus, and system provides an integrated viewer with one user interface and one API provides the ability to view, program, redline, and measure DWF and DWG files. In accordance with one or more such embodiments, the present invention provides an intelligent drawing redlining tool for easily and quickly drawing or annotating a drawing. For example, using the tool, a user can click the mouse over the first point of an arc segment. A bulge spacing function may then be utilized to define the length of an arc (also referred to as bulge spacing). In accordance with one or more embodiments of the invention, the bulge spacing function comprises holding down an arc defining key such as the key while the second point of the arc segment is selected. Thereafter, the bulge spacing of the first arc segment (the distance of the arc between the first and second points) is utilized for the remaining arc segments of the enclosed polyline/path. Thereafter, the user merely moves the mouse around the drawing and embodiments of the invention automatically draw arcs with the defined bulge spacing. To enclose the shape (also referred to as closing the polyline), the user moves the cursor on top of the beginning or first point of the first arc segment wherein embodiments of the invention automatically close and complete the shape. Consequently, a closed path that is not symmetrical can be drawn around odd shaped objects quickly and easily.

    摘要翻译： 一种方法，装置和系统为集成的查看器提供一个用户界面，一个API提供查看，编程，红线和测量DWF和DWG文件的能力。 根据一个或多个这样的实施例，本发明提供了一种用于容易且快速地绘制或注释图形的智能绘图重绘工具。 例如，使用该工具，用户可以单击鼠标超过弧段的第一个点。 然后可以使用凸起间距函数来定义电弧的长度（也称为凸起间距）。 根据本发明的一个或多个实施例，凸起间隔功能包括在选择弧段的第二点的同时按住弧定义键，例如键。 此后，第一弧段的凸起间距（第一和第二点之间的弧的距离）用于封闭的折线/路径的剩余弧段。 此后，使用者仅将鼠标移动到绘图周围，并且本发明的实施例自动地绘制具有确定的凸起间距的弧。 为了包围形状（也称为折线关闭），用户将光标移动到第一弧段的开始点或第一点的顶部，其中本发明的实施例自动关闭并完成形状。 因此，不能对称的封闭路径可以快速，容易地围绕奇怪的物体绘制。
