I have a couple of them, again I'm not an extremely advanced user.Most of them are thing I see that Revit can do and AC can't
1. Constrains. When you move an element the other elements move with them, especially between walls and floors when you change the story heights or the width of the assemblies, this is a must.
2. Dimensions, a la Revit, where the dimension can change the length of the element, or that you can use eq/eq. Better continuous dimensions.
3. This is an old one and I know there is a add somewhere but Ceilings please!!!!
4. Updated GUI. I don't want the mess of Revit, but I know it can be improved.
5. Improvement of Complex profiles. Reveals.
6. Buy Cadimage and incorporate those features to Archicad standard. Sorry Cadimage

7. Keep improving the stairs, especially to extend railings for ADA.
8. ADA check clearances would be nice.Code compliance would be orgasmic.
Thanks.
