Choose a Rep for the spring. The choices are Side, Wire 3D and Solid.
NOTE: Plain and squared end springs can be created as solid objects.
For side representations: After you pick the location for the top of the spring, you will be prompted to select an axis orientation for the spring. If you press ENTER at this point, a dialog box will appear which allows you to enter the angle into a text field. The number of coils for 3D springs is limited due to KeyCreator's limit on the number of nodes per spline. If a 3D spline with more coils is needed, create two springs and join them together. 2D springs are drawn in the current construction plane, not the current view.
