Hi Nats,
I can see your not convinced by anyones argument yet! It's a shame this discussion is getting a bit personal. Will everyone please lighten up and use this opportunity to compare and contrast the different programs and their perceived ease of use. The more people with different opinions, the better the forum is.
Anyhoo, thanks for posting up the picture of the project, It is much easier to see what your talking about.
Regarding the design of the building, I don't see anything that can't be built using the standard tools in ArchiCAD. What things specifically could you not work out how to build? What were you anticipating would need 'programming' in order to work?
If it was a building shaped like an organic blob, I would hold my hands up and say yes, use another program, but happily your building is very simple. It looks rectilinear in nature with a simple pitched roof. The windows and doors are rectangular. These all are things that ArchiCAD can do very easily and quickly.
Personally, to model that building to a level suitable for planning drawings, I'd be suprised if it would take me any longer than 3 hours using the standard ArchiCAD parts, and probably an equal time to set up and annotate all the drawings and enhance the plans and elevs with 2d entourage. I'm sure it could be done even quicker if pushed! A lot of the speed comes from both having a good set of preset materials, wall types and windows and also knowing exactly what tool you need to accomplish a particular task before you come to it. Trial and error is very slow.
In terms of co-ordination, what happens if you change part of the design? How do you ensure that you have updated every plan/elev/section/3dview that may show the changed area?
Would it be possible to see an example of the plans you produce using the combo of Sketchup and Autocad? It would be interesting to see if there was any bits that couldn't be done using a live model in AC.
And please, this is not a war! We all want the same thing really!
