使用C#三维绘图控件快速搭建DXF查看程序

本例使用AnyCAD .Net三维图形控件快速实现一个DXF文件的读取、显示、导出JPG、PNG、PDF的应用。

代码：

using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using AnyCAD.Platform;
 
namespace DxfViewer

    {
        private AnyCAD.Presentation.RenderWindow3d renderView = null;
 
 
        public MainForm()
        {
            InitializeComponent();
 
            this.renderView = new AnyCAD.Presentation.RenderWindow3d();
            this.renderView.Location = new System.Drawing.Point(0, 27);
            this.renderView.Size = this.Size;
            this.renderView.TabIndex = 1;
            this.Controls.Add(this.renderView);
        }
 
        private void MainForm_Load(object sender, EventArgs e)
        {
            this.renderView.View3d.ShowCoordinateAxis(true);
            this.renderView.View3d.ShowWorkingGrid(false);
 
            renderView.ExecuteCommand("ShadeWithEdgeMode");
            renderView.ExecuteCommand("TopView");
              <br>            //设置下背景色，像AutoCAD那样
            ColorValue clr = new ColorValue(33f / 255f, 40f / 255f, 48f / 255f, 1);
            renderView.SetBackgroundColor(clr, clr, clr);
            this.renderView.RequestDraw();
        }
 
        private void MainForm_Resize(object sender, EventArgs e)
        {
            if (renderView != null)
                renderView.Size = this.Size;
        }
 
        private void openToolStripMenuItem_Click(object sender, EventArgs e)
        {
            OpenFileDialog dlg = new OpenFileDialog();
            dlg.Filter = "DXF (*.dxf)|*.dxf";
 
            if (DialogResult.OK == dlg.ShowDialog())
            {
                AnyCAD.Exchange.DxfReader reader = new AnyCAD.Exchange.DxfReader();
                if (reader.Read(dlg.FileName, new AnyCAD.Exchange.ShowShapeReaderContext(renderView.SceneManager)))
                    renderView.RequestDraw();
 
            }
 
            renderView.View3d.FitAll();
        }
 
        private void pDFToolStripMenuItem_Click(object sender, EventArgs e)
        {
            SaveFileDialog dlg = new SaveFileDialog();
            dlg.Filter = "PDF (*.pdf)|*.pdf";
            if (DialogResult.OK == dlg.ShowDialog())
            {
                renderView.View3d.Print(dlg.FileName);
            }
 
        }
 
        private void imageToolStripMenuItem_Click(object sender, EventArgs e)
        {
            SaveFileDialog dlg = new SaveFileDialog();
            dlg.Filter = "Image File (*.jpg;*.png)|*.jpg;*.png";
            if (DialogResult.OK == dlg.ShowDialog())
            {
                renderView.View3d.GetRenderWindow().CaptureImage(dlg.FileName);
            }
        }
 
        private void dToolStripMenuItem_Click(object sender, EventArgs e)
        {
            renderView.ExecuteCommand("IsoView");
            renderView.View3d.FitAll();
        }
 
    }
