So I have had to reinstall Archicad after the program had a melt down today.
But when I opened my file I had this message when I went to view 3D: "WARNING! Wrong Edge List Direction in pgon 211." And gives me the option of STOP or CONTINUE.
If I hit continue then my system stalls and if I hit stop then it brings me to a 3D screen that is missing LOADS of my wall elements. The weird thing is that some of the identical walls are still there. You'd think if one had a problem, then they would ALL have a problem given they were created by multiple copying.
Clearly one polygon somewhere along the line has caused my file to have kittens but how do I find which one it is??
Hopefully someone is awake to help me. TIA.
