The Newel post is a unique column in the nodes of the sections of the railing path that supports, for example, the handrail.
Click the checkbox before the Newel posts button, select a profile or object, then specify the profile/object parameters and placing conditions. The specified newel post will be placed in each node of the Railing path.
Newel posts at turn may modify the distribution of primary and secondary balusters, therefore click Update button to see the changes in the preview window. The newel posts make the distribution period shorter on both ends of the Railing part by the width of a newel post.
