Template and superelevation

The template does not work correctly when applied superlevation. Superelevation is aplied at CA1_L and CA1_R with erratic results (see JPG).

Please, Someone can help me?

  • In order to test how superelevation is going to affect the template, Edit the template, and delete the slope contstraints from points CA1_L and CA1_R.  Now move those points up and down.  Do all the components behaving the way they should?  If not, then fix the constraints until the behaviour is correct.  Once this is done, then test the template end conditions using the Test button.  Do this at various slopes to ensure that everything is behaving the way it should.  Once you are satisfied, then reapply the slope constraints to CA1_L and CA1_R.

  • A quick tip:

    Any time you want to test how a point moves under some other control - Point Control, Parametric Constraint, Super Elevation, etc., delete one or more constraints, like Dennis suggests and use the move point tool. When using this technique, don't forget that you can use one or more Undo operations to restore any deleted constraints.

    This usually eliminates any accidental error creation that can occur when manually restoring constraints.

    When teaching others the Template Editor, I refer to this technique as the "Other Method of Testing Templates"

  • Hello, thanks for the suggestions. Everything seems to work correctly using a pivot  point and CA_1 point in constraint1 and constraint2 of all points in template (except for points of end conditions). I see some minor differences in the coordinates of points (approximately 0.0000001) of superelevated cross section but are negligible.
