Google Sketchup: Free 3D modelling tool
I’ve been using Sketchup for a while now (demo version), initially seeing it at the MacExpo in London last year. It’s a brilliant tool, taking (in my opinion) a whole new approach to 3D modelling. It couldn’t be easier to use.
Sketchup introduced a tool to export models straight into Google Earth, and the rest is history. The company was bought by Google, who now offer a free version of the software, which is limited in what you can import or export. You will still need the ‘pro’ version if you want to use the software in conjuntion with (i.e. exporting to) CAD or 3D visualisation software.
Archaeologists – it’s very easy indeed to import an AutoCAD DWG into Sketchup (or aerial photos, DEMs or a combination), and have fun trying out different interpretations. You can then export them to Google Earth.
It’s a lot of fun, and dare I say it, rather useful.

” I’ve always been a fan of having mobile internet access. It’s the geek in me I guess. That said, it’s also been handy for those down the pub moments where everyone is desperately trying to remember something (who was it who created Rupert the Bear again? Oh I know this. It’s on the tip of my tongue…) and after hours nobody can quite remember, and life takes on that single purpose to (apart from ale consumption) force the name out of the dusty depths of your memory.
Thanks for that very thorough review. I have been using MarsEdit but just tried ecto today and agree with your assessment. One thing you didn’t mention was the iPhoto integration. It seems to just upload the image without an option to resize — is that right?
