Types

type BoltParms

type BoltParms struct {
	Thread      string        // name of thread
	Style       CylinderStyle // head style "hex" or "knurl"
	Tolerance   float64       // subtract from external thread radius
	TotalLength float64       // threaded length + shank length
	ShankLength float64       // non threaded length
}

BoltParms defines the parameters for a bolt.

type CylinderStyle

type CylinderStyle int

const (
	CylinderCircular CylinderStyle
	CylinderHex
	CylinderKnurl
)

func (CylinderStyle) String

func (c CylinderStyle) String() (str string)

type KnurlParams

type KnurlParams struct {
	Length float64 // length of cylinder
	Radius float64 // radius of cylinder
	Pitch  float64 // knurl pitch
	Height float64 // knurl height
	Theta  float64 // knurl helix angle
}

KnurlParams specifies the knurl parameters.

type NutParms

type NutParms struct {
	Thread    string // name of thread
	Style     CylinderStyle
	Tolerance float64 // add to internal thread radius
}

NutParms defines the parameters for a nut.

type PanelHoleParams

type PanelHoleParams struct {
	Diameter    float64 // hole diameter
	Thickness   float64 // panel thickness
	Indent      r3.Vec  // indent size
	Offset      float64 // indent offset from main axis
	Orientation float64 // orientation of indent, 0 == x-axis
}

PanelHoleParms defines the parameters for a panel hole.

type StandoffParams

type StandoffParams struct {
	PillarHeight   float64
	PillarDiameter float64
	HoleDepth      float64 // > 0 is a hole, < 0 is a support stub
	HoleDiameter   float64
	NumberWebs     int // number of triangular gussets around the standoff base
	WebHeight      float64
	WebDiameter    float64
	WebWidth       float64
}

StandoffParams defines the parameters for a board standoff pillar.
