and exterior corners of the wrectangle. It also
maintains the thickness of the section. Default=on.
Co rner Radius 1—Controls the r adius of all four
interior and exterior corners of the section.
IfSyncCornerFilletsisturnedoff,CornerRadius
1 controls the radius of the four exterior corners
of the wrectangle.
Co rner Radius 2—Controls the radius of the four
interior corners of the wrectangle.
Corner Radius 2 is only available when Sync
Corner Fillets is turned off.
Note: Take care when adjusting these settings.
There are no constraining relationships between
them. Therefore, it’s possible to set an inside
radius(CornerRadius2)thatisgreaterthanthe
length and width of the sides.

Use Channel to create a closed “C” shaped spline.
You have the option to specify the interior and
exterior corners between the vertical web and
horizontal legs of the section.
