After much blood, much sweat, and lots of tears, (along with endless curses) and many, many thanks to all the tutorials/help on this site I managed to create the First Canadian Place (Bank Of Montreal) tower in Toronto, setup as a ploppable landmark. It's my first attempt so not great, but I'm surprisingly happy with it.
Have a problem though.
The problem being the building doesn't line up with the blue plop 'marker'/guide in game (see screenshot). The lot is 6 wide by 4 high. When I select the building and go to plop it, it's offset to the left by 3 squares, and down by 2 squares. Then when I build it, trees still appear 'in' the building I'm guessing because of this, and the 'developed' land (6x4 plot) doesn't line up. I used PIMX to create the lot using my exported GMAX/BAT model. Which leads to me to my 2nd issue, as I'm using PIMX because the Lot Editor crashes and I can't get it working (I've included the error details - anybody else come across this?). This isn't as big an issue if I can continue to use PIMX though.
I don't know how to fix the placement to get it to line up in game. It seems like the lot in PIMX appears correct based on the yellow/red/blue/green guidelines.
Any ideas?
Thanks
