Archicad is powerfull enough to fulfill the needs of users and do complex projetcs,
BUT
Graphisoft doesn't listen.... and that's the point
* Users recommand Graphical GDL editor : no answer , a powerful unusable language is a miss, and it won't be used when all A'rchitects deal with time, no time to learn, no time to write codes, we need to design parametric objects in 3D
BIMobject won't release any app for archicad and this is a great step BACKWARD for archicad agains it's competitors
* Unfinished Basic fonctionnalities : Correctly presented walls after SEO :'( walls are used in 99.99% in our projects, a HUGE problem like incorrect representation will push users to switch to another sowftware who can represent things correctly , when i talk with my students about SOE , they say : i can't work with a software who represents things wrong, i'll switch to revit .... ( workaround arents enough )
Stairs, Railings, mesh ( environment design) roof tools, need to be more user friendly with less contraints ..
* More organized UI , lots of menu are placed in a very hidden or inappropriate place, and difficult to reach,
* Cost estimation : establishing mathemathic operations bitween schedule columns / elements propreties so we can calculate cost per Square meter or cubic meter etc, excell would be needed just for final tweaking
* Independance from 3rd party solutions, A lot of basic things are done with 3rd party solutions , cladding, roofing, terrain modelling, electrical wiring, tiling ( wurtain wall is here for such a job but not 100% operating )
