Adding a Reference Line

In the Family Editor, you can add a reference line in any view and use the same drawing tools and techniques used when adding model lines. When you sketch a reference line, it displays as a single line.

In a view where the visual style is set to hidden line or wireframe, the sketched line displays as a solid line and the plane extents display with dashed lines.

To add a reference line

To use reference lines and linear dimensions to control model geometry

  1. In the Family Editor, click Create tabDatum panel (Reference Line).
  2. Using the drawing tools, sketch the line.

    The line displays as a solitary solid line until selected or when highlighted during preselection.

    Example of reference lines sketched as a polygon

    When selected or highlighted, the associated planes display according to the active view.

  3. Align the face of a model element to the reference line and lock it.
  4. Add a dimension line referring to the reference line and label it as an instance or type parameter.
  5. Flex the model by changing and applying a new value within the Family Types dialog.
