Thanks Lloyd for the correction.Yes, Woodturner PRO calculates the volume in real-time just like it does in Segment PRO. You'll see the volume calculation at the bottom of the screen.
A bit of clarity as to why you can't transfer designs between SegPro and WTPro...
Woodturner PRO keeps all details of every row in the file that is saved to the disk. This is what makes the software so flexible in that you are in charge of everything that happens. SegPro, on the other hand, is a rules-based piece of software that does not need to keep track of details by row because the design consists of a Profile with a specific height and the software follows its rules to construct the vessel for you. You are in control of setting the defaults the software uses but beyond that, the software is in charge and that is what makes SegPro so fast and easy to use.
Because the two programs are night and day different, it isn't possible to transfer designs between them. The key is to made the decision before you start as to whether the bowl you are going to design is a 'standard' segmented bowl or a non-standard project where you want to vary details down to the segment level. If it will be 'standard', SegPro will let you design it in far less time than it would take with WTPro. If it is non-standard, WTPro is your only option but it gives you a complete suite of capabilities that far exceeds SegPro.
If you design a Feature Ring in Lamination PRO, that design can be imported into either SegPro (as a species using the 'Export Image' button), or directly into WTPro by first selecting the target row by double-clicking the row and then click the Export to Woodturner PRO button in Lamination PRO and follow the instructions. This is very simple.
I hope that helps.

My memory at time fails. For some reason I thought WTP did not give volume. I should have checked before posting.
