Polyline flag (bit-coded; default = 0): 1 = This is a closed polyline (or a polygon mesh closed in the M direction) 2 = Curve-fit vertices have been added. I can not work with this, is there a an existing command lisp that reduces the number of line segments in a polyline. You must use Fit to see the effect of Tangent. A rectangle is an example of a polyline that you are already familiar with. Undo the inserted vertex by exiting the Edit Vertex option (X.J) and typing U.J. To select a single arc or line segment, press Ctrl while clicking the segment. Don't worry, you have options to fix this. 32 = The polygon mesh is closed in the N direction . 04-12-2012, 12:42 PM #2 Click the Options button. The vertices that define the polyline however are not spaced equally. This will convert your polyline into a “polyline spline” which looks like a spline but inherits properties of the 2D polyline. Simplify polyline. Before the selected spline is converted to a polyline, the following prompt is displayed: Specify a precision <10>: Enter a new precision value or press Enter. Optionally adjust the values of the user settings: Number of iterations and Intermediate polylines.
