Quatermain,
Sorry about being slightly misleading in the previous post.
To answer your question,
Yes, Cedrus perform better in PT slabs design (this includes Regular and Irregular Slabs)
You can still use Cedrus to design a PT beam but the result is not as detail when you use RAPT. For an instance, RAPT allows you to do adjustment for Tendon centroid distance "e", Duct wall thickness, Anchor friction... etc
However, the only thing i found out limitation of Cedrus compared to Safe and RAM is, Safe and RAM allows you to input the column ABOVE and Below (taking account into its stiffness) whereas Cedrus only allows you to input the Column Below.
If you want to do equivalent frame method, stick with RAPT.
To be frank with you i have not tried using any of them to design ribbed and waffle slab but if you are dealing with highly irregular Slabs, go for Cedrus.
Safe's limitation is, even though it provides (wizard/typical design/initial model) but once you get out of the Regular Slabs module, you will have more trouble, adjusting the Tendons profiles and defining the design strips than doing a complete new module in Cedrus.
