	* Create a fixed circular or fixed parabolic vertical curve by specifying a high or a low point. For more information, see To Add Fixed Vertical Curves to Profiles.		* Create a fixed circular or fixed parabolic vertical curve by specifying a high or a low point. For more information, see To Add Fixed Vertical Curves to Profiles.
			'''Note:''' These curves are not backward compatible with AutoCAD Civil 3D 2018. You can use the Convert Curves command to convert the fixed parabolic curves so they are compatible with AutoCAD Civil 3D 2018, but the fixed circular curves cannot be converted.

			For more information, see [https://help.autodesk.com/view/CIV3D/2019/ENU/?guid=GUID-48BB985A-D671-43E3-81E9-91ADB0FD1BA2 To Change the Constraint Type of Vertical Curves for Backward Compatibility].

			* A new property, Total Curve Length, is now included in the Profile Entities Vista and Profile Layout Parameters dialog box when you are using the Entity Based view in the Profile Layout Tools. This value shows the total vertical curve length.

			The existing property, Length, shows the length of the solved portion of the curve geometry, such as when tangents are attached along the curves

			* The Total Curve Length property is available for all vertical curves.
			* The Total Curve Length property is editable for fixed circular and fixed parabolic vertical curves that you create by specifying a high or low point.

			For more information, see Profile Layout Parameters Dialog Box and Profile Entities Vista.

			* The ApplyAOR option in the Subassembly Composer now has the following effects on points and links for rail subassemblies as they appear in the Subassembly Composer flowchart:
			** Geometry before ApplyAOR is specified for an item in the flowchart is not adjusted when cant is applied.
			** Geometry after ApplyAOR is specified for an item in the flowchart, and which is created so that it is directly or indirectly dependent on the item which has ApplyAOR defined, is adjusted when cant is applied. Because of these effects, you can achieve the expected cant behavior by specifying the ApplyAOR option for one or more links and make subsequent points and links in the flowchart dependent on those links.

			A validation process occurs in the Subassembly Composer to check whether the geometry in rail subassemblies that depends on items which have ApplyAOR specified will be updated correctly. Open previously-created rail subassembly PKT files that use cant in the Autodesk Subassembly Composer for Autodesk Civil 3D 2019 and update them if needed.

			For more information, see About Cant Validation in the Subassembly Composer and About Defining Cant for a Subassembly.

=== Opening an Autodesk Civil 3D 2019 Drawing in a Prior Version of AutoCAD Civil 3D ===

* Drawings saved in Autodesk Civil 3D 2019 can be opened in AutoCAD Civil 3D 2018. '''Note:''' Fixed vertical curves created with the Fixed Vertical Curve (Parabolic, High/Low Point, Parameter, Length) and Fixed Vertical Curve (Circular, High/Low Point, Parameter, Length) commands are not backward compatible with AutoCAD Civil 3D 2018. See the Profiles section below for more information.
* To open an Autodesk Civil 3D 2019 drawing and view the Autodesk Civil 3D objects in a version of the software prior to AutoCAD Civil 3D 2018, set the PROXYGRAPHICS system variable value to 1 in Autodesk Civil 3D 2019 to save the graphics with the drawing and then use the Save As command to save the drawing to a prior drawing file format. When you open the drawing in a prior version of the software, the Autodesk Civil 3D objects will be displayed as proxy graphics.
