Free transitions

New free transitions generator engine.

If you are looking for a program that can produce any pattern [transition] you are at the right place!

Most sheet metal programs have extensive libraries for transitions but you are still tied up to the available ones.

With LITIO new version 2.0 you can make your own customized patterns.

In general, a pattern 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.

Then you just need to start LITIO2, 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 exists] and its development.

Have a look at this video tutorial.




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.

* Some restrictions apply [see user manual].
Note, that the following entities are not accepted: arcs [convert arcs to polylines using the PEDIT command] nor ellipses [use ellipse pattern of LITIO 2.0], and resulting 3D objects cannot have concavities.
