  1. Select Constructions on the Layer toolbar.

    Construction elements are used to aid in the definition and proper constraint of the final symbol geometry.

  2. Create a point at the origin of the drawing sheet. This task is most easily accomplished by clicking Point and entering [0, 0] coordinates on the ribbon. Click Lock to lock the point.

  3. Define the necessary horizontal and vertical construction lines relative to the symbol origin.

  4. Define and constrain any construction elements (lines, circles, and so on) as needed.

    Profile symbols can use all constraint types, including horizontal and vertical constraints.

  5. Select the Default layer on the Layer toolbar. For the Default symbol, sketch the detailed physical profile cross-section, beginning by attaching it to the drawing sheet origin point. This point defines the origin of the cross section and will determine its default placement within the model.

  6. Constrain the profile, but do not over-constrain. Profile symbols can typically use all constraint types, including the Horizontal/Vertical constraint on the Relationship toolbar.

  7. Select the Dimensions layer on the Layer toolbar. Dimension the profile.

    When two geometric elements will always have the same value, use the Equal constraint, and dimension one element, rather than dimensioning both.

  8. Variables are created for each of the dimensions. If refinement of the variables is required, click Tools > Variables. Rename, change default values, and add formulas as needed.

  9. Sketch the contour for other symbol representations on their own layers, constraining the new geometry to the Default layer geometry.

    • The Collinear constraint is commonly used to constrain geometry to Default layer geometry.

    • Additional representations typically created are Simple Physical and Symbolic. For more information, see Cross-Section Symbol Representations.
