Most sheet metal programs have extensive libraries for transitions, but you are still tied up to the available ones.
With LITIO 2.0 you can draw your own customized patterns.
A transition can be defined by its two ends.
For example, your transition may be defined by two polylines e.g., an irregular pentagon as the base [end 1] and an oblique ellipse as the top [end 2]. It is easy to generate both in AutoCAD or GStarCAD. Place them in your CAD's 3D space according to your needs.
Start LITIO 2.0, choose this option [Free pattern from two 3D curves], click on both entities, define some few parameters [thickness and internal fillet radius], and you get the resulting 3D developable surface [if it 'mathematically' exists] and its development.
You can create transitions just by clicking any two valid entities (either 3D meshes created by Litio 2.0; or 2D and 3D polylines; or circles, located in AutoCAD/GStarCAD's 3D space.*
Thus, LITIO 2.0 gives you much more transitions than the ones available through its standard dialogue boxes.
The program is ideal for a company that makes hoppers or Ys of different sizes and measures. And its price is very convenient. ... It is very easy to use: anyone with a notions of metalworking and CAD can handle it. ... I use it frequently and It always does the job for me. Alex Gamper

You can draw customized sheet metal transitions just by picking two valid entities.
For this particular case, the transition is defined at its base with a polyline that is made by one third of a circle, two lines from the arc ends to the arc center, all with a fillet radius, and a circle at the top.
