通过API获取Autodesk Inventor中的连接元素

Question

我们有Autodesk Inventor并创建了一个c#插件。

在这里，我们像这样循环遍历所有的对象:

foreach (CurrencyAPIv2.IAssetInstance s in objects)
{
var c = s.NativeObject as ComponentOccurrence;
}

我们如何获得一个对象的连接对象(一个对象被连接到它)。还有它所连接的连接器的信息

Answer 1

Michael Navara:

你能更具体一点吗?CurrencyAPIv2。IAssetInstance不是Inventor API的成员

using CurrencyAPIv2 = Autodesk.Factory.PublicAPI.Currency.v2;

Answer 2

我们用xml文件解决了这个问题，该文件也可以在AttributeHelper:

中查看。

void LoadConnectors(Document document, List<ConnectionElement> connections, List<ConnectedComponent> components)
{
var am = document.AttributeManager;
var d = new Dictionary<string, string>();
var entities = am.FindObjects("*", "*");
foreach (var e in entities)
{
try
{
dynamic o = e;
foreach (AttributeSet attrS in o.AttributeSets)
{
foreach (Inventor.Attribute a in attrS)
{
d.Add(o.Name, a.Value as string);
}
}
}
catch(Exception)
{ }
}
foreach (var element in d)
{
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.LoadXml(element.Value);
var connectionNodes = xmlDoc.SelectNodes("//ObjectData[@Type='42']");
var componentNodes = xmlDoc.SelectNodes("//ObjectData[@Type='38']");
// Verbindungen
if (connectionNodes.Count > 0)
{
var link1Node = xmlDoc.SelectSingleNode("//ObjectData/Link1") as XmlElement;
var link2Node = xmlDoc.SelectSingleNode("//ObjectData/Link2") as XmlElement;
var connection = new ConnectionElement();
connection.Name = element.Key;
connection.Link1 = link1Node.GetAttribute("VAL");
connection.Link2 = link2Node.GetAttribute("VAL");
connections.Add(connection);
}
// Komponenten
else if (componentNodes.Count > 0)
{
var componentConnectorNodes = xmlDoc.SelectNodes("//ObjectData/Connector");
var componentConnectors = new List<ComponentConnector>();
foreach (XmlNode cc in componentConnectorNodes)
{
var idNode = cc.SelectSingleNode("Id") as XmlElement;
var displayNameNode = cc.SelectSingleNode("DisplayName") as XmlElement;
var connector = new ComponentConnector();
connector.DisplayName = displayNameNode.GetAttribute("VAL");
connector.Id = idNode.GetAttribute("VAL");
componentConnectors.Add(connector);
}

if (components.FirstOrDefault(x => x.Name == element.Key) != null)
{
components.FirstOrDefault(x => x.Name == element.Key).Connectors.AddRange(componentConnectors);
}
else
{
var component = new ConnectedComponent();
component.Name = element.Key;
component.Connectors = new List<ComponentConnector>();
component.Connectors.AddRange(componentConnectors);
components.Add(component);
}
}
}
}
