"Object reference not set to an instance of an object." exception when converting obj to gif

Using your sample code:

var document = Aspose.CAD.Image.Load(@“C:\Users\niels\Desktop\Workspace\keanu.obj”);
// Create Instance of GIF Options
var options = new Aspose.CAD.ImageOptions.GifOptions();
// save OBJ as a GIF
document.Save(@“C:\concierge\foo.gif”, options);

I’m getting:

image.png (22.9 KB)

I’ve tried with several difference obj files.

Can you please share the source file reproducing the issue on your end. Please also first try using latest Aspose.CAD for .NET as well on your end.

I’m using the latest version from nuget.
