As it happens it was Sketch up. Can I open my sketchup file in another program and create STL from that?

Hi everyone I have been having an issue for some time now and its causing me great headaches. After I have done all my design work and made an STL from it I find that when I load into Cura and put into preview I have surfaces I did not add and I think they print out that way too. How can I stop this? first pick is what I want (above) Preview shows surfaces all across X Ray show red where the surface I wanted touches the outer rim, what does this mean? Thanks in advance, Glyn
