cad.net 封装一个填充类
本文主要是介绍cad.net 封装一个填充类，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！
封装一个填充类
渐变填充部分参考了才鸟的书里的代码,但是我改的也挺多的...
调用
namespace JoinBox
{
public partial class CmdTest
{
/// <summary>
/// 测试填充
/// </summary>
[CommandMethod("CmdTest_hatch")]
public void CmdTest_hatch()
{
var dm = Acap.DocumentManager;
var doc = dm.MdiActiveDocument;
var db = doc.Database;
var ed = doc.Editor;
ed.WriteMessage($"{Environment.NewLine}填充测试");
//这里是选择已有图元加入填充
int actionNum = 4;
if ((actionNum & 1) == 1)
{
var psr = ed.GetSelection();
if (psr.Status != PromptStatus.OK)
return;
db.Action(tr => {
new HatchInfo(psr.Value.GetObjectIds(), 100)
.Mode1PreDefined("ANSI34")
.Build(tr, db);
});
}
if ((actionNum & 2) == 2)
{
var psr = ed.GetSelection();
if (psr.Status != PromptStatus.OK)
return;
db.Action(tr => {
new HatchInfo(psr.Value.GetObjectIds(), 100)
.Mode2UserDefined()
.Build(tr, db);
});
}
if ((actionNum & 4) == 4)
{
var psr = ed.GetSelection();
if (psr.Status != PromptStatus.OK)
return;
db.Action(tr => {
new HatchInfo(psr.Value.GetObjectIds(), 100, Math.PI / 2)
.Mode4Gradient(HatchInfo.HatchGradientName.Linear,
Autodesk.AutoCAD.Colors.Color.FromRgb(0, 0, 0),
Autodesk.AutoCAD.Colors.Color.FromRgb(152, 35, 100))
.Build(tr, db);
});
}
}
}
}
