A SheetMetal BaseBend object is derived from a Part Feature object or, if it is inside a PartDesign Body, from a PartDesign Feature object, and inherits all its properties. It also has the following additional properties:
Data
{{Properties_Title|Parameters}}
-
Bend Side|Enumeration: \"Relief Type\", defines on which side of a profile curve the thickness applies. {{value|Outside}} (default), {{value|Inside}}, {{value| Middle}}. (not used for plates)
-
Bend Sketch|Link: \"Wall Sketch object\". Link to the profile/outline sketch.
-
Mid Plane|Bool: \"Extrude Symmetric to Plane\". The length of a profile or the thickness of a plate extends to one side of the sketch plane if
False
(default) or symmetrically to both sides ifTrue
. -
Reverse|Bool: Reverses the direction of a profile extrusion or a plate thickness. Default:
False
. -
length|Length: Extrusion length of a profile. Default: {{value|100,00 mm}}. (not used for plates)
-
radius|Length: Inner radius of automatically added bends. Default: {{value|1,00 mm}}. (not used for plates)
-
thickness|Length: Wall thickness of a sheetmetal profile or plate. Default: {{value|1,00 mm}}.
