The CreateCurbs creates new featurelines for the TopBack, TopFace, BottomFace and, optionally, the GutterLip, relative to either the selected Featureline's elevations or a surface, from an existing featureline or polyline and an existing surface. You may specify one of these options as to what the selected object represents:
In all 4 instances, if the selected object is a polyline, a new Featureline will be created in it's place; you may specify to delete the original object. The Featurelines are created based on the direction of the original object, where the Back of curb is on the Left, the the others follow to the right in this order: Top Face, Bottom Face, Lip of Gutter. Should you desire to 'flip' them, you will need to UNDO, Reverse the Object's direction, then run the command again. The Featurelines may be added to the surface, or another surface, as breaklines.
Note that the command will not run if the drawing does not have a surface defined.
Type CreateCurbs at the command line or select it from the Ribbon. You may preselect the objects (ONLY LightWeightPolylines and Featurelines are supported at this time) or select them at the prompt. If this is the first time running the command, or if you enter SE at the selection prompt, you will be presented with the Settings form in which to select a Site, Surface, and provide a Breakline group name, along with a number of optional items as shown. Selecting the "Use Target surface for breaklines option" enables you to select a different surface in which to add the breaklines, leaving the original surface unchanged. If you then enable the option "Create new surface per breakline pair", the dialog will change to allow you to type in a prefix to be used for these surfaces, each surface wil be numbered, starting at 001.
Toggling the "Paste to Surface" option will automatically paste the surface(s) used/created into the surface specified here. Note that in version through 2011 we have no way to know if a surface has been previously added as a paste, so multiple enries may be found in the Surface definition edits. All but one of these may be safely removed afterwards, although we have seen no problems with leaving them as they are.
These settings will now be used in future runnings of the command, even in other drawings. If the specified Surface and/or Site is not available in a drawing, you will again be presented with the Settings form.
