convert files from adobe indesign (cs3) to scribus 1.5.2 (freeware) -- 2 - 09/11/2017 07:16 EST

I need some files to be converted: The manual "3D - Einsteiger Übungsbuch" has 176 pages, The manual "2D - Einsteiger Übungsbuch" has 147 pages, the manual "Elements Handbuch" has 201 pages, the manual "Elements Tutorial" has 107 pages, The manual "ElementsCAM Tutorial" has 150 pages. At the moment all manuals are created with indesign in DIN A4 size. We cutted the paper in the middle and made two DIN A5 manuals. Now the size in Scribus 1.5.2 has to be DIN A5, so we can export and print it through a printing shop. I think the files can be exported within indesign as an eps file and afterwards imported to scribus as I read in newsgroups...
