ANYCAD-based DXF File Reading and conversion, anycaddxf reading

The purpose of this article is to learn about ANYCAD and attach specific operations during this time, so that new users can take less detours.

I am a beginner in C # and have never been familiar with programming. I learned from my teacher during the summer. The first task was to open the DXF file with C #. I thought the task was very simple, BUT it is useless to search a lot on the Internet (for a newbie ), I accidentally saw an article titled how to quickly set up the reading, display, and conversion of DXF files to JPG, PNG, and PDF files based on AnyCAD.net. I learned about this ANYCAD control, however, when I entered the code in this article, I found that it was not very useful for a newbie. I could only say that it opened the door for me to learn.

AnyCAD Graphics SDK is a professional and comprehensive 3D Graphics application development kit. It is a CAD Platform Based on OpenCASCADE, it can be used to develop applications such as 2D/3D model design, computer simulation, and pre-and post-processing of finite element. According to the function module, the AnyCAD Graphics SDK Professional edition includes geometric modeling, 3D visualization and data exchange module. The Enterprise Edition adds the Data Management Module Based on the Professional Edition. AnyCAD Graphics SDK has two versions:. Net and C ++. the. Net version supports the WinForm and WPF interface frameworks, and the C ++ version supports interfaces such as MFC, Qt, and wxWidgets.

First, let's take a look at ANYCAD. SDK. This is a dynamic link library. For example, if you want to use the renderView in the code below, you must first define it for use. Where is the definition? Yes, it is in the SDK, so you must first download the anycad sdk. However, due to copyright issues, you only have to purchase the SDK after the trial period and the students have special care. I will not go into details here.

19      public MainForm()20         {21            InitializeComponent();22 23            this.renderView = new AnyCAD.Presentation.RenderWindow3d();24             this.renderView.Size = this.panel3d.ClientSize;25            this.renderView.TabIndex = 1;26             panel3d.Controls.Add(this.renderView);27         }

After you download the SDK (Note: Pay attention to the VS and SDK versions), the first step is to add a reference so that you can use the encapsulated function. The most important thing is to copy the added SDK file to your project.

Then add USING, such:

The following is all the code:

I hope these things can help you, even if it is a bit, I am very happy!
