Unfolding Ellipses & Ovals (Symmetric & Asymmetric)
A special extension is available in Sheet Lightning v5 to create and unfold elliptical and oval section pipes and cones by simple parametric design. This is a
specialist design extension for companies wilth applications for the capability and is a powerful extension to the base product.
PURCHASE - Ellipse & Oval Design Extensions for Sheet Lightning v5
Elliptical pipes and cones can be designed with of without taper and skew (i.e. parallel end offset).
Oval pipes and cones can be designed with sections that basically comprise of four tangentially connected arcs. This means that not only ovals can be created
but very unusual shapes with different arc radii - such as kidney or egg sections.
Fig: Asymmetric Oval - The asymmetric oval, as shown, enables the design of oval parts
that are completely assymetric in terms of opposite radii - therefore encompassing kidney sections and numerous others because the section arcs can have a negatve radius value. The
design capability is further advanced by the ability to either taper and/or skew the part. These designs are unfolded into their flat shapes by a simple command.

Fig: Elliptical Sections - these sections are similiar to ovals but conform to the perfect
ellipse design. They can also be designed with taper and skew.
