请问高手，polyline怎么转换成polyline2d啊？
point3dcollection m_ptcoll = new point3dcollection(); doublecollection m_buglecoll = new doublecollection(); for (int i = 0; i < m_pl.numberofvertices; i++) { m_ptcoll.add(m_pl.getpoint3dat(i)); m_buglecoll.add(m_pl.getbulgeat(i)); } polyline2d m_pl2d = new polyline2d(poly2dtype.simplepoly, m_ptcoll, m_pl.elevation, m_pl.closed, m_pl.getstartwidthat(0), m_pl.getendwidthat(m_pl.numberofvertices - 1), m_buglecoll); m_pl是你的原多段线 m_pl2d是生成的2维多段线
谢谢兄弟，按照你的思路应该还要把原来的多段线删除吧
