Autocad Vba Polyline Bulge
Jigging an AutoCAD polyline with arc segments using. Using Autodesk.AutoCAD. To allow users to input bulge factors for polyline segments that are being.
2D and 3D polylines, rectangles, polygons, donuts, and 3D polygon meshes are all polyline variants and are edited in the same way. AutoCAD recognizes both fit polylines and spline-fit polylines. A spline-fit polyline uses a curve fit, similar to a B-spline. There are two kinds of spline-fit polylines: quadratic and cubic. Both polylines are controlled by the SPLINETYPE system variable.
A fit polyline uses standard curves for curve fit and utilizes any tangent directions set on any given vertex. To edit a polyline, use the properties and methods of the Polyline, Polyline2d, or Polyline3d object. Use the following properties and methods to open or close a polyline, change the coordinates of a polyline vertex, or add a vertex.
