The solution is as follows: 1. Save the DWG format file as a DXF format file with AUTOCAD first, and select the AutoCAD R12/LT12 DXF file type. 2. Open EZCAD2, select “File” – “Input Vector File”, and then adjust the image size to mark.
“Uncombine” the drawing first, then “Group” them, and uncheck “All calc” in the “Hatch” option to calculate separately. The fill line distance should be less than the size of the triangle.
