Create ANY sheet metal transition
in AutoCAD, GStarCAD, ZwCAD and BricsCAD with LITIO 2.0
Do you want to create your own customized transition?
Then 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 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.
* 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.
