Should I transform all the model to mesh before exporting it to STL or whatever? For some reason, my STL file has too many issues and the 3rd printing software is not even reading simple things like columns.

I am trying to make plans for a project myself and i need .stp-files. Any tips on how to fix this is much aprecciated. <BR /> <BR /> Is the best to use rhino to make the files? My plan is to cut from 12mm plywood, wich means I actually only need 2D-drawings. But I guess it still needs to be .stp. <BR /> <BR /> Any tip helps out! <IMG src="https://community.graphisoft.com/legacyfs/online/emojis/icon_smile.gif" style="display : inline;" /> Mon, 23 Sep 2019 16:09:46 GMT https://community.graphisoft.com/t5/Collaboration-with-other/From-pln-to-stp/m-p/272096#M35656 Anonymous 2019-09-23T16:09:46Z https://community.graphisoft.com/t5/Collaboration-with-other/From-pln-to-stp/m-p/272097#M35657 Same problem. <BR /> <BR /> Seems like exporting to .stp would be an important feature to have, since making custom parts to be CNC fabricated is becoming increasingly common. AC can export stereo lithography already--is there some difficulty translating the software? I don't want to have to spend $800 on Rhino.
