There are a lot of nice things in SE but the user interface is not very good. There is a real problem in not being able to go back and fix or change things. The user interface is also hard to use because it relies heavily on a plethora of icons to show where you are at in a sequence of operations. It is hard to tell whether the icons are active or not because there is little contrast. For people with trifocals or even limited vision this interface presents some real challenges.
The feature tree in the SE that I am using just does not compare to the feature tree in SW for ease of use in determining feature order and rollback capabilities. For example finding the parents and children of features is non-existent.
SE is very sensitive to mouse technique. It seems to be very easy to get it to not do what you want if you make a little mistake with the mouse like jiggling when hitting the LMB.
SE has the bad habit of throwing out the sketch when a feature is deleted and it also has the bad habit (that Pro/E also had) of not letting you exit a sketch if there is a problem. And it doesn't do a very good job of showing what the problem is that it is complaining about.
On the other hand SE seems to be fairly robust, creates compact files and performs reasonably well.
The method SE uses to show relations between different profile entities is confusing and IMHO much harder to use that the method used in SW2004.
SE does do very well at drawings. It can keep track of changed dimensions, open a drawing without the part being available and do a lot more drafting on Isometric views than SW can. On the other hand it doesn't have some obvious things like being able to dimension a diameter in a revolved profile or switch display of a dimension from radius to diameter.
I haven't figured out how to create macros or do VBA > >
