Hi all,

I need an upside-down triangle (to make wall for stairs). It looks like this: http://uphinh.ssc.vn/images/609a.png

I found a triangle on http://www.sweethome3d.com/support/foru ... ttachments but it's opposited to my need (imagine a horizontal line). I can't find CopyAsNewFeature add-on to create it my own. Can you help me?

Thank you in advance...!

Best regards,
