To Refine Constraints Between a Section Line and View Geometry

Typically, constraints are inferred between the view geometry and the section line. In most cases this is sufficient. However, under exceptional circumstances you may need to add additional constraints.

1. Click Layout tab Modify View panel Symbol Sketch. Find
2. Click the section line to constrain.

   The symbol sketch mode starts. With the exception of the view geometry, all geometry (including the section line) is dimmed. A polyline that coincides with the section line indicates the cutting plane.

3. Add the required constraints to constrain the cutting plane.
   Tip: If you require construction geometry to implement the constraints, simply add the geometry. All geometry added in symbol sketch mode is construction geometry. They are not visible when you exit symbol sketch mode.
4. On the ribbon, click Finish Symbol Sketch.

   The cutting plane converts to the section line. The construction geometry becomes invisible.
