Hi, i dont know about LO 2015, but i think its the same procedure, just follow the instruction. if u think your CAD is blank, just change your CAD background colour to white. it will show up, just change all the line to white or by layer. but the only problem is, i dont know how to change the text colour globally... the default color is black. it will be painful to select the text and turn it white one by one. maybe someone could help us out...
