         Hi :)

    I have a question about the object-link-port in Xpresso. I added this kind of ports to my node.

    Whats the difference between a Link Port and an Object Port? I would like to connect the Object(Link?)-Output-Port of a Polygon Object with my Inport-(Link / Object)-Input-port and edit some points of it.

    GeData iptdataA = GvGetPortGeData(bn, iptA, run);
    //This is the part which is called in the Calculation Method of my Node.

    I didn't work with BaseObjects, CDAtom and I have to check their dependencies, yet.
    I have no clue :-(

    Thanks for help

    You have to use the GVGENERALOBJECT description type. Please have a look at the following example code. It's a node with an object input that prints the name of the object, much like the result node.

    Hi, works fine :) Thank you...

    Is it correct to use GetTypeName() to differ the several objects (camera, spline, etc..)? After that I could cast it to the object, right?

    Thanks :)

    Hi!

    Wrote the needed lines to my project. It works with a BaseObject.
    But what about the other objects? With GetLink(..) I get a BaseLink2D which hands its members to BaseTag and BaseObject.

    -->On BaseObject:    ...->GetName()   (works)
    -->On BaseTag:        ...->GetName()    (doesn't work)!!!! ????

    The BaseTag is derieved from the BaseList2D. I am confused about it.
    Could someone throw a light on my prob? Thx
