SupportStructure¶

class pyslm.support.SupportStructure(supportObject=None, supportVolume=None, supportSurface=None, intersectsPart=False)¶

Bases: abc.ABC

The Support Structure is the base class representing all definitions of support structures used in PySLM. This includes attributes that link to the source part and the original support faces or features of an object and shared utility methods for the calculation of useful properties.

It stores properties that describe the type of support identified during its generation and stores relevant data connecting this such as the original support surface (supportSurface) and the support object or part (supportObject) and if the support self-intersects with the part (supportObject).

Attributes Summary

`intersectsPart`	Does the projected support structure intersect with the originating part
`supportObject`	The originating object that the support structure is generated for
`supportSurface`	The support surface identified on the originating part
`volume`	Returns the volume of the Support Geometry

Methods Summary

`flattenSupportRegion`(region)	The function takes a support surfaces and flattens this as a projected polygon.
`geometry`()	Returns the geometry representing the support structure
`projectedSupportArea`()	Convenience function returns the total projected surface area of the support.
`supportArea`()	Convenience function returns the total surface area of the support region.
