It has been very helpful when designing complex parts that have many features such as internal contours or pockets etc..
The software allows me easy access from my laptop anywhere I am which helps tremendously during design stages where there are issues related to changes made by another designer who may not be able to see them immediately due to time constraints at work. This can sometimes cause confusion if someone else makes an error while working remotely but this does help eliminate errors between designers once final details become known.
