I've got previewIcon using BlockTableRecord.PreviewIcon. But what a pity, the icon size is 32*32 which is too small. I need larger one. The previewicon size is even smaller than the preview icon of Insert Block Form.
I searched the forum and found an article Generating larger preview images for all blocks in an AutoCAD drawing using .NET. It seems very great but It comes out that the solution is for AutoCAD 2014 and higher version only.
I hope that someone will give me tips to solve the problem, thank you!
