Modelling in Real World Co-ordinates

Pros

Cons

Greater integration with other design data, such as geotechnical or infrastructure models in real world co-ordinates

May need project seed file if real-world co-ordiates lie outside the ‘Solids Working Area’ (Refer to Co-ordinates and the SWA section below)

Automatic scheduling for items in the real world positions (i.e Pile layouts, bridge abutments etc)

Exchange with other software (such as GSA or ArchiCAD) may be limited by their co-ordinate system accuracy.

Easier model re-use ( i.e CityModelling)

View manipulation is more complicated
