CAD to 3D PDF

The following CADto3DPDF sample illustrates how you can create a 3D PDF from a CAD page:

CS
VBNET

C#	Copy Code
using System.IO; using ImageGear.Formats; using ImageGear.Formats.CAD; public static void CadTo3DPdf(string inFile, string outFile) { ImGearCADPage page = null; // Load the file. using (FileStream fileStream = new FileStream(inFile, FileMode.Open, FileAccess.Read)) { page = (ImGearCADPage)ImGearFileFormats.LoadPage(fileStream); } // Save the CAD file as a 3D PDF file. CADPDFSaveOptions options = new CADPDFSaveOptions(); options.PRCMode = CADPDFSaveOptions.PRCModeOption.BREP; page.SaveOptions["PDFSaveOptions"] = options; using (FileStream fileStream = new FileStream(outFile, FileMode.Create, FileAccess.Write)) { ImGearFileFormats.SavePage(page, fileStream, ImGearSavingFormats.PDF); } }

Copy Code

using System.IO;
using ImageGear.Formats;
using ImageGear.Formats.CAD;

public static void CadTo3DPdf(string inFile, string outFile)
{
    ImGearCADPage page = null;

    // Load the file.
    using (FileStream fileStream = new FileStream(inFile, FileMode.Open, FileAccess.Read))
    {
        page = (ImGearCADPage)ImGearFileFormats.LoadPage(fileStream);
    }

    // Save the CAD file as a 3D PDF file.
    CADPDFSaveOptions options = new CADPDFSaveOptions();
    options.PRCMode = CADPDFSaveOptions.PRCModeOption.BREP;
    page.SaveOptions["PDFSaveOptions"] = options;

    using (FileStream fileStream = new FileStream(outFile, FileMode.Create, FileAccess.Write))
    {
        ImGearFileFormats.SavePage(page, fileStream, ImGearSavingFormats.PDF);
    }
}

VB.NET	Copy Code
Imports System.IO Imports ImageGear.Formats Imports ImageGear.Formats.CAD Public Sub CadTo3DPdf(inPath As String, outPath As String) Dim page As ImGearCADPage ' Load the file. Using fileStream As New FileStream(inPath, FileMode.Open, FileAccess.Read) page = ImGearFileFormats.LoadPage(fileStream) End Using ' Save the CAD file as a 3D PDF file Dim options As CADPDFSaveOptions = New CADPDFSaveOptions() options.PRCMode = CADPDFSaveOptions.PRCModeOption.BREP page.SaveOptions.Add("PDFSaveOptions", options) Using fileStream As New FileStream(outPath, FileMode.Create, FileAccess.Write) ImGearFileFormats.SavePage(page, fileStream, ImGearSavingFormats.SVG) End Using End Sub

VB.NET

Copy Code

Imports System.IO
Imports ImageGear.Formats
Imports ImageGear.Formats.CAD

Public Sub CadTo3DPdf(inPath As String, outPath As String)
    Dim page As ImGearCADPage

    ' Load the file.
    Using fileStream As New FileStream(inPath, FileMode.Open, FileAccess.Read)
        page = ImGearFileFormats.LoadPage(fileStream)
    End Using

    ' Save the CAD file as a 3D PDF file
    Dim options As CADPDFSaveOptions = New CADPDFSaveOptions()
    options.PRCMode = CADPDFSaveOptions.PRCModeOption.BREP
    page.SaveOptions.Add("PDFSaveOptions", options)

    Using fileStream As New FileStream(outPath, FileMode.Create, FileAccess.Write)
        ImGearFileFormats.SavePage(page, fileStream, ImGearSavingFormats.SVG)
    End Using
End Sub

Setting the PRCMode option to either BREP or MESH should output a 3D PDF. It is recommended that PRCAllInSingleView be set to true so the CAD page will export to a single PDF page.
