Dear colleague, The only difference of the multi-storey car park from other classical barme systems is that there are 2 inclined ramps for vehicle traffic, one for exiting and the other for landing, and it consists of modeling inclined beams at different levels and the floors connected to them. You can easily create this data with idestatic. As for the sample project, if you write your e-mail address, it would be more appropriate for me to send you the special images and drawings (because it is not ethical to share them here because it is with one of the other programs I use other than ide).
