The Grid class has been added to the .NET API in the Autodesk.AdvanceSteel.Modelling namespace.

The class inherits from Autodesk::AdvanceSteel::ConstructionTypes::ConstructionElement.

In addition to the methods from the base class and the RTTI methods, it contains the following methods:

Constructor:

Grid()

Enum:

eGridType
eNumberingType

Properties:

bool AxisFrame
Matrix3d CS
eGridType GridType
string NumberingPrefix, NumberingStart, NumberingSuffix
eNumberingType NumberingType
bool VerticalSeries

Methods:

This gets an array containing all the elements in the Grid. This included elements that were created as neighbors to other elements. Check the GridElement class for further details.

int GetAllElements(out GridElement[] elements)
double getDeltaXInSequence(int sequenceIndex)
int getNumElements()
setDeltaXInSequence(int sequenceIndex, double deltaX)
setNumberingValues(IEnumerable<string> values)
setNumElementPerSequence(int sequenceIndex, int numElements)
setTextLocation(GridElement.eLocation location)     
updateLength(double length)
updateWidth(double width)

Delivered Classes:

Class Grid1D

Methods:

Grid1D(Matrix3d gridCS, double length)
Grid1D(Matrix3d gridCS, double length, double width, int numAxes)

Class GridCircle

Constructor:

GridCircle(Matrix3d gridCS, double length, Point2d midPt)
GridCircle(Matrix3d gridCS, double length, double width, int numAxes, Point2d center)

This class has been added to the .NET API in the Autodesk.AdvanceSteel.Modelling namespace.

The GridElement class provides read only access to the grid element's axis and labels.

Enum:

eLocation

ctor:

GrConsturidElement()

Methods:

This method is used to get the Element's axis as a Curve3d object. The Curves will be transformed from the given curveCS to WCS; This means that if you want to get the Curve3d objects in the Grid's UCS, you need to provide curveCS = Matrix3d.kIdentity as a parameter. If you want the Curve3d objects in WCS, you need to provide curveCS = grid.CS().

GetCurve(ref Curve3d asCurve, Matrix3d curveCS)

Get the text label at the specified location of the grid axis, kStart or kEnd.

string GetTextAt(eLocation loc)

This class has been added to the .NET API in the Autodesk.AdvanceSteel.Modelling namespace and it is derived from PlateBase.

Constructor:

FootingIsolated(Plane plnBase, Point3d ptCenter, double dXLength, double dYLength)
FootingIsolated(Plane plnBase, Point3d ptCenter, double dRadius)

This class has been added to the .NET API in the Autodesk.AdvanceSteel.Modelling namespace.

It contains a series of statics used to define editable object properties when the object is constructed by a Joint.

The LifeSign class has been added to the .NET API in the Autodesk.AdvanceSteel.Utils namespace. This class is used when Advance Steel is called from external processes and signals that Advance Steel is "alive" and the current operation is calculating.

Methods:

Marks that the current process is calculating; this method must be called from the Advance Steel code from time to time:

Mark(string currentOperation)

Checks that Advance Steel is still "alive" by checking the current time with last marked time:

bool IsAlive()
static LifeSign LifeSignManager()

The Utils class has been added to the .NET API in the Autodesk.AdvanceSteel.Utils namespace.

Methods:

EnsureGraphicsUpdate()

() - makes sure that AutoCAD receives focus after some Advance Steel changes in order to make sure AutoCAD is able to refresh the graphics on the screen. Only use this if your code changes are not properly reflected on the screen (this could sometimes happen when a modeless dialog is opened).

The GeometryUtils class has been added to the .NET API in the Autodesk.AdvanceSteel.Geometry namespace. This class contains a few static const values.

MarkUndo (this method was moved from DocumentManager).

Constructor:

DocumentAccess()

This class is intended to be used in conjunction with a "using" statement - on construction it starts transactions and locks the document, upon destruction it commits the transaction and releases the lock on the document.

This structure has been added to the .NET API in the Autodesk.AdvanceSteel. ConstructionTypes namespace.

Members:

FilerObject CreatedObject
int Tag
string JointTransferId
IEnumerable<int> Attributes

They are all located in the Autodesk.AdvanceSteel.ConstructionTypes namespace.

IFiler - interface defining an object responsible for serialization (used especially by joints):

int ReadVersion()
void WriteVersion(int nVersion)
object ReadItem(string itemName)
void WriteItem(object value, string itemName)
int Length()
Dictionary<string> GetItems()

virtual void Load(IFiler filer)

The IRuleUIBuilder interface has been added to the .NET API in the Autodesk.AdvanceSteel. ConstructionTypes namespace. This interface can be used to automatically build Joint pages and controls just by specifying the control type, default values and page information. When using this, the API user no longer has to manually create Joint page resources and handle UI interaction.

Enum:

bool IsMirroring ()

New method:

 bool IsEqualTo ( Plane plane, Tol tol)

New properties:

 int VertexCount
 Point3d []Vertices
VertexInfo []VertexInformation

New methods:

EnsureContinuity ( )

Note: Adjusts vertices so that they match the true line-arc or arc-arc intersections so that we do not get a self-intersecting error for contours detected from bodies with "recovered" arcs, etc. It does not add/remove/change the order of vertices, but only slightly moves some of them. This function should not normally be used, except when constructing polylines from at least an arc and when it is suspected that the given vertices are not perfectly adjusted.

 Reinitialize ( int changeVertexAllowed, Tol tol)

Note: This function performs a number of useful things - it eliminates coincident vertices, consecutive collinear edges and arcs on the same circle (with the given tolerance tol, only if changeVertexAllowed is true) and it also reinitializes the normal and validity of the polyline; it should be called whenever you are not sure that the polyline is already in a "initialized" state (e.g. you didn't construct it yourself) and it will be passed to other functions (which may assume that the polyline is initialized).

Deleted methods:

Point3d [] GetVertices ()
 VertexInfo [] GetVertexInfo ()
int GetVertexCount ()

Changed methods:

int SeparateBy ( Polyline3d [] lines, out Polyline3d [] resPolylines, double gap)

Class ProfileType

New method:

 bool  GetKDistance (out double dDistance)

Class PlateBase

New method:

 getOuterContour ( Matrix3d inCS, bool bGetFromBody, bool bReinit, BodyContext::eBodyContext bodyContext, bool bCheckWeldigPrep)

inCS - the contour will be retuned in this CS.

bGetFromBody - if true, the contour is obtained from the plate body; if false, the contour will be calculated from the plate parameters. This method is faster, but it only takes into account corner features (chamfers and fillets), and only one for each corner.

bReinit - calls reinitialize() on the returned contour, if true.

bodyContext - if bGetFromBody is true, this context is used for obtaining the body from which the contour is returned; otherwise, it controls whether fillets and chamfers are taken into account (through its OuterContours property - all predefined contexts have this set, except kUnNotched).

bCheckWeldingPrep - deprecated.

New method:

getContourPolygon (out Point3d [] ptsContour)

Class FeatureObject

Removed:

The change is a consequence of renaming WeldLevel to WeldPoint.

Changed methods:

WeldLevel Connect ( FilerObject objToconnect, Matrix3d inputCs)

WeldPoint Connect ( FilerObject objToconnect, Matrix3d inputCs)
