If you do not see the Variable Manager then turn it on in Applications Add-Ins.</p> <p><img src="http://communities.bentley.com/resized-image.ashx/__size/550x0/__key/CommunityServer-Discussions-Components-Files/5922/5367.clothoid.JPG" border="0" alt="" /></p> <p>A parabolic or circular curve in vertical alignment is always stroked as a linestring.</p> <p>Regards,</p> <p>Mike</p><div style="clear:both;"></div>
