Hello to everyone. Here is the question, for those who use not only inventor, but also other CAD programs : has it ever happened to you to make a part in one program, but if you try to make it  using another, it's not feasible to make it exactly the same. To explain it better, i have drawn a sketch in solidworks, which i intend to use as a path for a sweep feature. It is fully defined with dimensions. When i try to make it using inventor, it just cannot be done! If i try to use the same values for the dimensions it becomes over constrained. It can be made, but a little differentiated. In this specific example, a radius which is R3 in solidworks can go up to R2.8 in inventor. Isn't this absurd? Not to mention the feature sweep which doesn't allow me to produce exactly the same part . But the main problem is the sketch. Anyone? Thanks in advance for the answers.
