Entities with SAT/SAB structure

Entities with SAT/SAB structure

Certain entities store their structural data in the ACIS SAT/SAB format. These entities can be partially exported in 2D wireframe mode. The supported entities include:

• 3DSOLID objects: box, sphere, pyramid, wedge, cone, cylinder, torus, polysolid
• SURFACE: planar, extruded, revolved, swept
• REGION

Below is the example of export result (DWG file on the left part, PDF result on the right).

Exporting ACIS entities does not require any special options. To optimize drawing size, especially when drawing contains ACIS entities exclusively, consider using the cadImage.UpdateSize() function to adjust the initial drawing dimensions accurately.

using (CadImage cadImage = (CadImage)Image.Load(sourceFilePath))
{
	cadImage.UpdateSize();
	
	CadRasterizationOptions rasterizationOptions = new CadRasterizationOptions();
	rasterizationOptions.Layouts = new string[] { "Model" };

	PdfOptions pdfOptions = new PdfOptions
	{
		VectorRasterizationOptions = rasterizationOptions
	};
	cadImage.Save("output.pdf", pdfOptions);
}
