    Locking the origin of a line based family in the host family

    Dears,

    I have created a line based revit family that I am nesting in other family. The family consists of several trusses that need to be arrayed and rotated (basically a tower crane jib). The family works well and rotates well, but I need to FIX it's origin so that it always rotates around the same origin as it suddenly moves from the origin while I flex the family several times.

    Note: I am trying to module a tower crane Jib that can be arrayed and rotated and the length and width of its module be changed. My approach was to create a parametric module (one unit) then nested that into a line based family so that I can array it there and give it a rotation parameter, then nested that to the main family host. I will appreciate any other tips or approaches to achieve my goal in other ways

    Regards
    Karzan

    Welcome to the forum.

    Make this family work-plane based, and nest it into another family that has a reference line controlled by parameters in length and rotation. In the host, set the plane of the reference line as the current workplane, then draw the line-based family. Link parameters and align and lock endpoints.

      Has anybody tried this with a line-based detail component? I have a line-based component that I would like to host inside of another family (also detail component), and have the reference line of the host family control the angle of the hosted family. The end points of the embedded line-based family flex with the reference line (even if the angle changes - weird), but will not match the angle.

      Any suggestions?
