IWorkspace interface

Overview
The IWorkspace interface represents the Work-Space manager in the Altium Designer which deals with project and documents and their related attributes and options. This interface object is the starting point and upon querying this object, it can return currently open projects, number of projects, installed libraries, and create a new document for example.

Remember the projects need to be compiled first, before you can invoke the GetWorkSpace function to obtain the IWorkSpace interface and its descendant interfaces which represent actual objects in Altium Designer.

It is highly recommended not to hold an interface of the Workspace manager, but re-query the workspace manager everytime the access to the information within is required.

IBus interface

Overview
The IBus interface represents a bus object on the schematic sheet. Buses are special graphical elements that represent a common pathway for multiple signals on a schematic document. Buses have no electrical properties, and they must be correctly identified by net labels and ports.

When a schematic document is compiled, bus objects have inferred objects (wires with netlabels on them) in memory that aids the connectivity and navigation features within Altium Designer.

IChannelClass interface

Overview
The IChannelClass interface is a PCB Channel class object interface for an existing Channel Class on a PCB document. An existing Channel (room) class contains members of specific components. Each component within a Channel Class object can either be a member or not.

The ‘All Components’ Channel Class exists in every PCB document by default, it includes all Components in the document. It is not possible to change which components are members of that Channel class, but the user has full control over which components are members of any other Channel classes (which are created and named by the User).
Notes
Inherited from IObjectClass interface.

The IComponentImplementation interface is associated with an IPart/IComponent interface in terms of model linking. Note that the IComponent interface is inherited from the IPart interface.

A model represents all the information needed for a component in a given domain (a model can be a PCB footprint, Simulation file or a Signal Integrity model). A model is also called an implementation.
Each schematic component can contain links to different model implementations such as PCB, Signal Integrity and Simulation models. Only one model of a particular model type (PCB footprint, SIM, SI, EDIF Macro and VHDL) can be enabled as the currently linked model, at any one time.

A model can be represented by external data sources called data file links. For example, pins of a component can have links to different data files, as for signal integrity models. We will consider each model type in respect to the data file links.

For PCB footprints, the data file link and the model is the same since the external file is the PCB footprint library.
For simulation models, there can be no data file links because these models are defined using the Spice format.
However for signal integrity models, each pin can have different pieces of information represented by ibis data files. These signal integrity models can have multiple data files, that is, each pin of a component can have a separate IBIS file. A signal integrity model can however use the Altium Designer’s central Signal Integrity database.

Thus depending on which model type, you can have a number of data file links. Each data file link describes the model name, the path to where the library is stored in and what sort of model it is.

Overview
The INetClass interface is a PCB Net Class object interface for an existing NetClass on a PCB document. An existing Net class contains members of specific Net objects. Each Net within a NetClass object can either be a member, or not. The 'All Nets' Net Class exists in every PCB file by default; it includes all Nets in the document. It is not possible to change which Nets are members of that Net Class, but the user has full control over which Nets are members of any other Net Classes (which are created and named by the user).
Notes
An INetClass interface is inherited from the IObjectClass interface.

IParameter interface

Overview
The IParameter interface is a parameter object interface to an existing parameter object on a schematic sheet. There are two types of parameters – system parameters which are owned by a schematic document and parameters owned by certain schematic design objects.

A parameter is a child object of a Parameter Set, Part, Pin, Port, or Sheet Symbol object. A Parameter object has a Name property and Value property which can be used to store information, thus the parameters are a way of defining and associating information and could include strings that identify component manufacturer, date added to the document and also a string for the component's value (e.g. 100K for a resistor or 10PF for a capacitor).

Each parameter has a Unique Id assigned to it. This is used for those parameters that have been added as design rule directives. When transferring the design to the PCB document, any defined rule parameters will be used to generate the relevant design rules in the PCB. These generated rules will be given the same Unique Ids, allowing you to change rule constraints in either schematic or PCB and push the change across when performing a synchronization.

An equivalent object representation is the ISch_Parameter class in the Sch API reference.

IPart interface

Overview
The IPart interface is the interface of an existing schematic part on a Schematic sheet. A part object is “part” of a component, that is, a multi-part component consists of part objects. For example a multiple gate integrated circuit has duplicate gates, and that a component represents the multi-part gate and a part represents the gate itself.

An equivalent component object representation is the ISch_Component class in Schematic API. The ISch_Component interface represents a component that can contain links to different model implementations such as PCB, Signal Integrity and Simulation models. Only one model of a particular model type (PCB footprint, SIM, SI, EDIF Macro and VHDL) can be enabled as the currently linked model, at any one time.

IPin interface

Overview
The IPin interface is a pin object interface to an existing pin object on the schematic. Pins are special objects that have electrical characteristics and are used to direct signals in and out of components. Pins connect directly to other pins, wires, net labels, sheet entries or ports.
Notes
The IPin interface is inherited from the INetItem interface.
The pins are part of a schematic component, thus if you wish to have access to the pins, invoke the DM_Pins and DM_PinCount method call from the part object interface.
An equivalent Pin object representation is the ISch_Pin interface in Schematic API Reference
Example

 For J := 0 to Doc.DM_ComponentCount - 1 Do Begin     Comp := Doc.DM_Components(J);     //Comp.DM_Footprint;     //Comp.DM_Comment;     For K := 0 to Comp.DM_PinCount - 1 Do     Begin         Pin := Comp.DM_Pins(K);         PinName := Pin.DM_PinNumber;         // Check for parts of a multi-part component that are not used in the project         // then add 'No Net' for unused pins...         If Pin.DM_FlattenedNetName = '?' Then             // these pins of the part is not used on the schematic.     End; End;

IRule Interface

Overview
The IRule interface represents the one of the rules attached to a parameter within the PCB Layout directive (as a Parameter Set object with a small flag symbol) on a net aware object on a schematic object. A parameter set object can be placed on the schematic sheet by the Place » Directives » PCB Layout menu item.

This PCB Layout directive allows you to assign PCB layout information to a net in the schematic. When a PCB is created from the schematic, the information in the PCB layout directive is used to create relevant PCB design rules.
