With our change to XM, it seems that we can no longer modify existing or newly placed Leader Lines. Where text is attached to a Leader Line or not, it seems that the Leader Line and the Terminator are no longer attached, after they are placed. I am currently working with Microstation v8 xm and i have a data set with 3d contours. The contours have been converted to line string (as per spec) i have noticed that the elevation of each edited contour, either by extending line, inserting vertices or even moving the contour to another position will change its elevation height to +/-10000m.
SettingDescriptionMethodSets how the dropped element is constructed. Equal Arc Length — The B-spline curve is evaluated evenly along the arc. Each segment has the same arc length, as defined by the value for Number.
Equal Chord Length — The B-spline curve is evaluated at a given number of points such that the distance between each successive point is the same. Fixed Chord Length — The distance between each pair of successive points evaluated is the same as the chord length. Max.
The drop curves tool is MS8 takes a curve, ie spline/arc and converts it to a 'line string' the autocad equivalent of a polyline. One its methods is to specify how many points you want along that line and it goes ahead and divides the curve up.I'm after something similar in autocad that gives the same effect as when you explode a spline-fit poly.One way I thought it could be done is to read the coordinates of a spline from its entity data and draw a polyline from those. Then polyedit it to a spline-fit poly and explode it from there.Just wondering if autocad had something that does it before I go ahead and write the code for the above procedure. Ok, i got it:o)The way to do this in autocad is to draw a 'preliminairy' using the Polyline commands.

This is going to be all straight lines for now.Then convert it into a spline using the PEdit command. Once this done, you can you can use the grips or the coordinates entry data to re-shape it as required.Now you can explode this Spline using Explode, breaking it into Lines objectsThen you can convert those lines into polylines and join them using the PEdit command again.- -For some reason, a Spline created directly from the spline command cannot be exploded, but a spline created from a Pline conversion can, explaining my confusion heh.continuation.The end result of this is going to be a smooth curved.looking. polyline, made of straight segments. If you try to edit it at this point using grips, you'll only stretch straight line segments.When you 1st draw your 'preliminairy' in straight polylines, before converting it into a spline, the number of grips(or editing points) will be determined by the number of line segments in your polyline (ie: one grip at each endpoint of each polyline segments) So the more points you create, the more flexible your spline is going to be before you explode it.
