改变3dpolyvertex 中的点
建立一个 3dpoly using autodesk.autocad.runtime; using autodesk.autocad.databaseservices; using autodesk.autocad.applicationservices; using autodesk.autocad.editorinput; using autodesk.autocad.geometry; public class gilsclass1 { public void create3dpoly() { point3dcollection pts = new point3dcollection(); polyline3d my3dpoly = new polyline3d(poly3dtype.simplepoly, pts, false); double[] ptsarr = {0, 0, 0, 10, 10, 10, 0, 10, 10}; int i = 0; while (i < ptsarr.length) { pts.add(new point3d(ptsarr(i), ptsarr(i + 1), ptsarr(i + 2))); i = i + 3; } draw3dpoly(my3dpoly); } internal objectid draw3dpoly(polyline3d my3dpoly) { database db = hostapplicationservices.workingdatabase; editor ed; application.documentmanager.mdiactivedocument.editor(); autodesk.autocad.databaseservices.transactionmanager transmgr = db.transactionmanager; transaction trans = transmgr.starttransaction; try { blocktablerecord btr = (blocktablerecord)trans.getobject(db.currentspaceid, openmode.forwrite); btr.appendentity(my3dpoly); trans.addnewlycreateddbobject(my3dpoly, true); trans.commit(); } catch (autodesk.autocad.runtime.exception ex) { ed.writemessage("error message: " + ex.message); } finally { if ((my3dpoly != null)) { my3dpoly.dispose(); } } return my3dpoly.objectid; } }
