The Design Standard will also check for kinks in the alignment. The Design Standard will supply values for the element creation tools (such as minimum radius and transition lengths) as well as direct which prompts are offered for a construction tool. Vertical Geometry curves should be Parabolic, verify the Vertical Curve Type when using the Vertical geometry Complex by PI tool. The Vertical geometry uses the Horizontal's Feature Definition for it's settings. Also, if the Rule Deactivation is toggled ON, then you will not be able to use Manipulators to modify your alignment.Ī Horizontal alignment is 2 dimensional until the Vertical alignment is set Active, at which time the 3rd dimension is created. For example, if the Automatically Create 3D option is turned ON and you have an Active Terrain Model, then a Best-Fit Profile will automatically be applied to your alignment. This tool is used to connect the previously placed Elements.Įssentially, all other buttons on the Feature Definition Toggle Bar should be toggled OFF when creating Alignments. When done placing Alignment Elements, then set the Feature Definition to Alignment before using the Complex by Elements command. When it is functioning properly, then the Feature Definition of the Active Tool will display Use Active Feature. Note that when setting the Feature Definition on the Features Definition Toggle Bar for the first time, select the Feature and then toggle the Use Active Feature Definition button OFF and then ON to wake-up the Feature Override so it is recognized by the Active Tool. When creating any Alignment by Elements, set the Feature Definition to Alignment Elements. Also be aware that changing a DGN Model not only clears any Feature assignment, but it also clears the Design Standard. If you are uncertain which option to choose, check the documentation on Working Units.Ĭreating New Alignments (General Comments)Īlways use the DGN's Default model when creating and working with Horizontal Geometry.
There are two different methods for importing alignments from MX depending on whether the project drawings are based on US Survey feet or the older International foot seed files.įor US Survey Foot projects, continue with OpenRoads Horizontal Geometry - USSFįor projects with design file working units in Feet, continue with OpenRoads Horizontal Geometry - INTF However if the element (or alignment) is to be converted to an MX alignment, then the feature assignment is lost. There are also options to set the feature type. It can be found on the MicroStation menu, select Tools > Civil AccuDraw > Activate Toolbar. For more sophisticated constructions, use Civil AccuDraw. Advance to the Manipulators section to learn about editing an element.ĭesign Standards can be created and used for control of alignment. Elements can be edited by way of on-screen graphic Manipulators or adjusting the element's properties. Relationships between elements are preserved when things change. Locking some values may limit or otherwise affect the other values. In addition, any of the tool's criteria can be locked in the dialog panel at any time. The above cursor prompt graphic indicates that the Down Arrow will cycle thru the Placement Method options for that tool. The bottom right of the cursor prompt displays arrow head icons indicating which arrow keys to use at that moment. When the cursor offers options instead of a numeric value, the available options can be cycled through using the Arrow keys. Minimal prompts are also echoed to the MicroStation dialog. A Data Point (left mouse click) advances to the next prompt. Data presented on the cursor can be changed by keying in a new value followed by an Enter to accept the new value. The OpenRoads tools utilize cursor prompts, dynamic feedback, and on-screen manipulation to provide an interface that helps keep focus on your work. OpenRoads points use MicroStation Snap Codes. Geometry wise, OpenRoads offers both an Intersection Point and Element forms of construction. OpenRoads alignments are MicroStation Complex Elements.īecause OpenRoads uses MicroStation commands, the Undo command may become your favorite feature. OpenRoads tools are neatly found in OpenRoads on the General Geometry and Horizontal Geometry Task menus.
