I am very new to SketchUp and am having an issue when exporting a file as a .dae file and importing the same file into Blender not all of the features of the SketchUp file are being imported into Blender. I downloaded the “throw/judo mat” file from the 3D Warehouse and am trying to make a few slight modifications. I am adding a few simple rectangular lines to the mat as seen in the image below but when I export this and then import into Blender the grid I created in SketchUp does not appear in Blender. I have posted images below as well as attached the .skp file I am working with. Please let me know if you have any idea why the grid is not being reflected in Blender.
