draw civil 3d 2016 alignment from right to left

Geometry tools are coordinate geometry tools that use a heads-upward interface, persists user input, and preserves pattern intent. Results of these tools are intelligent graphic elements stored in the DGN and not in external files.

OpenRoads tools are neatly found in OpenRoads on the General Geometry and Horizontal Geometry Task menus. OpenRoads alignments are MicroStation Complex Elements.

Because OpenRoads uses MicroStation commands, the Undo command may become your favorite characteristic.

Geometry wise, OpenRoads offers both an Intersection Bespeak and Element forms of construction.

General

OpenRoads points use MicroStation Snap Codes. The OpenRoads tools utilize cursor prompts, dynamic feedback, and on-screen manipulation to provide an interface that helps continue focus on your work. Information presented on the cursor can be changed by keying in a new value followed by an Enter to accept the new value. A Data Betoken (left mouse click) advances to the next prompt. Minimal prompts are also echoed to the MicroStation dialog.

When the cursor offers options instead of a numeric value, the available options tin can exist cycled through using the Arrow keys. The bottom right of the cursor prompt displays pointer caput icons indicating which arrow keys to use at that moment. The in a higher place cursor prompt graphic indicates that the Down Pointer will cycle thru the Placement Method options for that tool.

In addition, any of the tool's criteria tin be locked in the dialog panel at any fourth dimension. Locking some values may limit or otherwise affect the other values.

Relationships betwixt elements are preserved when things change. Elements can be edited by way of on-screen graphic Manipulators or adjusting the chemical element's properties. Advance to the Manipulators section to learn about editing an element.

Design Standards can be created and used for control of alignment. For more sophisticated constructions, use Civil AccuDraw. It can exist institute on the MicroStation menu, select Tools > Civil AccuDraw > Activate Toolbar.

In that location are also options to set the feature type. However if the element (or alignment) is to exist converted to an MX alignment, and so the feature consignment is lost.

Import MX Geometry (SS4)

There are ii different methods for importing alignments from MX depending on whether the project drawings are based on US Survey feet or the older International pes seed files.

For United states of america Survey Foot projects, continue with OpenRoads Horizontal Geometry - USSF

For projects with design file working units in Anxiety, continue with OpenRoads Horizontal Geometry - INTF

If you are uncertain which option to cull, check the documentation on Working Units.

Creating New Alignments (General Comments)

Always use the DGN'due south Default model when creating and working with Horizontal Geometry. Also be aware that changing a DGN Model not merely clears whatever Feature assignment, but it besides clears the Blueprint Standard.

When creating any Alignment past Elements, set the Characteristic Definition to Alignment Elements. Note that when setting the Feature Definition on the Features Definition Toggle Bar for the first time, select the Feature and so toggle the Use Agile Feature Definition button OFF and then ON to wake-up the Feature Override and so information technology is recognized by the Active Tool. When it is operation properly, then the Feature Definition of the Active Tool will display Use Agile Characteristic. When done placing Alignment Elements, then prepare the Characteristic Definition to Alignment earlier using the Complex past Elements command. This tool is used to connect the previously placed Elements.

Essentially, all other buttons on the Feature Definition Toggle Bar should be toggled OFF when creating Alignments. For instance, if the Automatically Create 3D option is turned ON and you lot have an Agile Terrain Model, and then a Best-Fit Profile volition automatically be applied to your alignment. As well, if the Rule Deactivation is toggled ON, then y'all will not exist able to utilize Manipulators to change your alignment.

A Horizontal alignment is two dimensional until the Vertical alignment is prepare Active, at which fourth dimension the 3rd dimension is created. The Vertical geometry uses the Horizontal's Feature Definition for it's settings. Vertical Geometry curves should exist Parabolic, verify the Vertical Curve Blazon when using the Vertical geometry Complex by PI tool.

Pattern Standards Toolbar

The Pattern Standard will supply values for the element cosmos tools (such as minimum radius and transition lengths) besides as direct which prompts are offered for a construction tool. The Design Standard will also check for kinks in the alignment.

To open the Design Standard Toolbar, select Design Standards Toolbar from either the General Geometry or the Horizontal Geometry Task card.

This toolbar allows the selection of a Design Standard and also controls information technology'due south application to an OpenRoads element. From the left pull-down, select the desired Design Standard. From the right pull-down, select between Stopping or Passing Sight Distance. Next, click the Toggle Agile Design Standard button on the left of the toolbar to toggle the standard ON from the default of OFF. When ON, the push turns amber and all subsequent commands volition make use of the values contained in the standard. When OFF, the selected standard is ignored.

If a Design Standard is violated, so feedback is provided in two ways:

1. An icon appears on the element that has the problem. Hover near (over it is as well shut) the icon to reveal a tool tip report of the error.
2. In the Civil Message Center (Tools > Civil Geometry > Geometry Toggles > Ceremonious Message Middle).

Design Standards are very alignment oriented. There is limited value for using Design Standards for non-alignment constructions. To verify a Design Standard has been applied, use the Element Information tool on the element in question.

Set Design Standard

The Gear up Design Standard is for applying a standard to previously created ceremonious elements. However, the Design Standard Toolbar must exist open and the Toggle Active Design Standard push button must exist toggled ON earlier applying an Element Blueprint Standard.

From the General Geometry or the Horizontal Geometry Task menu, click on the Set Design Standard push. Next, choose the chemical element to which the blueprint standard volition be assigned. To verify that a Design Standard has been practical, utilize Element Information on the element in question.

Circuitous By PI

Complex By PI creates a linear element with curves based on user input of PI (point of intersection) locations. These curves can include transitions.

This is basically the OpenRoads version of MX'southward Quick Vertical alignment. As the command suggests, the resulting alignment is a Complex Element. This tool is found on the Horizontal Geometry Task menu.

Follow the dialog and/or the cursor prompts to guide your alignment construction. Data Points place the PI's. The value for the curves back radius is seeded on the cursor. To change the seed radius, enter the new value followed by an Enter. This back seed radius volition be used for all subsequent curves till it's changed. A Data Signal (left mouse click) advances to the next prompt. Select the Reset button to finish the placement of PI's.

OpenRoads Elements - Fixed Elements

Line Betwixt Points creates a line between ii user defined points.

Arc Between Points creates an arc. There are six Workflows for creating an arc:

• Start Point, Radius, and Sweep Angle (or length)
• Center Point, Radius, and Sweep Angle (or length)
• Start Point, End Point, and Pass-Thru Indicate
• Start Betoken, Pass-Thru Bespeak, and End Indicate
• Kickoff Direction, Terminate Betoken
• Kickoff Point, Cease Direction

Employ the Downwards Arrow central to bicycle through the Workflows. Follow the dialog and/or the cursor prompts to guide your element construction.

OpenRoads Elements - Free Elements

Line Between Arcs constructs a line between 2 previously placed arcs. This tool has the ability to apply both a dorsum and/or a frontward Transition (spiral) betwixt the arcs and the constructed line. This tool too has the ability to utilize both a back and/or a forrad Offset. Follow the dialog and/or the cursor prompts to guide your element construction.

In that location are four possible solutions and each solution is assigned a number. After the second arc is identified, the four possible solutions are displayed with their solution numbers. The position of the cursor directs which solution is taken. If your not paying attention, then you might have the incorrect solution.

The terminal prompt offers 4 Truncation Methods, choose from the post-obit:

1. None
2. Back
3. Ahead
4. Both (recommended for about situations)

Use the Down Pointer primal to cycle through the Truncation options.

Elementary Arc constructs an arc betwixt two previously placed elements. Like to Line Between Arcs, in that location are four possible solutions and the position of the cursor directs which solution is taken. If your not paying attention, then y'all might accept the incorrect solution. There are as well four Truncation methods.

Screw Arc Screw likewise constructs an arc between ii previously placed elements. Still this tool has the ability to optionally apply both a back and or frontwards transition betwixt the elements and the constructed arc. Follow the dialog and/or the cursor prompts to guide your element construction.

Notation that OpenRoads alignments are easy to accommodate afterward associates. Refer to the Manipulators section to learn well-nigh editing an alignment.

OpenRoads Elements - Float Elements

Similar to MX, these tools for Floating Elements are designed for constructing an chemical element with respect to ane other element. In addition in that location is an Kickoff choice and a Skew pick, both are features MX does not offer and are useful for the creation of intersections and ramps. There are ii workflows for float lines and two workflows for float arcs.

To Elements

Simple Line To Element and Simple Arc To Element constructs a line/arc to a base chemical element. Both of these commands require an Finish Signal that the new chemical element will laissez passer thru. Next, place the connecting element. If using the Arc To Element control, in order to change the arc'south projection, toggle the Paw option betwixt Clockwise and Counter Clockwise. Follow the dialog and/or the cursor prompts to consummate the element structure.

From Elements

Simple Line To Element and Unproblematic Arc To Element constructs an line/arc from a base of operations chemical element, COGO style. Both of these commands require the point of tangency and the new element is projected from there. Then follow the dialog and/or the cursor prompts to complete your element construction.

Note that OpenRoads alignments are easy to adjust after assembly. Refer to the Manipulators section to learn most editing an alignment.

Circuitous past Elements

Complex By Elements assembles a Circuitous Element of previously placed elements (lines and arcs). You are not limited to using OpenRoads elements to utilise this tool, whatever existing graphics may be selected. Therefore, be careful of your proximity to other elements when building a Complex past Elements.

Using the Automatic method, hover over the kickoff element until the directional arrow points to the desired direction. Left Mouse click to accept the chosen chemical element. At this signal, the circuitous path volition be highlighted. Left Mouse click again to accept the complex creation or Right Mouse click to Cancel.

Alternatively, using the Transmission method, select each element individually using the Left Mouse click. Be sure the directional arrow is pointed in the proper direction before option. Once all items are selected, Left Mouse click away from any MicroStation elements to accept the Circuitous Element creation.

Accelerate to the Manipulators department to learn about editing an alignment.

Manipulators

OpenRoads alignments are editable by selecting them with the MicroStation Chemical element Choice tool. The selected alignment highlights and additional graphics appear showing the alignment Manipulators. These manipulators enable adjustments to be fabricated to the alignment. Tool tips ever confirm which manipulator you are at. Relationships between elements are preserved whenever possible, this includes intersections.

The Text Manipulators display Lengths, Bearings and Radii which tin can be selected and lets you blazon in new values.

The Dots correspond drag handles that allows one to movement the points without constraint.

The Triangle or Arrow shaped elevate handle redefines the point with one or more directions constrained. The arrows that are parallel to the base line are constrained to change the distance only. The arrows that are perpendicular to the base line are constrained to change that management only. This insures that aspects of the alignment's geometry are held.

A MicroStation Snap icon displays if a point was created by a snap. Hovering near the betoken will display the normal manipulator. Click and move the dot to remove the snap constraint and supplant it with new constraints.

The Ceremonious AccuDraw drag handles display when a point was created with a Civil AccuDraw constraint. Text manipulators display the Civil AccuDraw constraints which were input. Hovering virtually the point will change it to a normal manipulator. Click and motility the dot to break the Civil AccuDraw constraint and replace it with new constraints.

As you zoom in and around the design, the position of the manipulators may modify. The software will attempt to display as many manipulators as are valid for the part of the particular displayed. This includes automatically moving a manipulator if necessary.

Note that Manipulators may exist toggled ON or OFF from the Element Selection console with the Disable Handles button.

Commencement Transition

Kickoff Transition constructs linear elements based on various methods of offsets from a base of operations element. The base chemical element may exist a line, arc, screw, or a complex element. There are four methods:

1. Unmarried Start Entire Element – The outset chemical element maintains a constant beginning along the entire length of the base element.
2. Single Get-go Partial – Same every bit above simply with additional command for Start and Terminate distance.
3. Variable First Taper – The offset is variable and defined by station and start at each terminate of the base element.
4. Ratio Defined Taper – The showtime element is defined by a station offset at the beginning, and and so the terminate point is defined by a ratio.

MX Transfer and Stationing

OpenRoads alignments may exist transferred to MX using the Full general Geometry task Consign to Native. Go to the Transferring an OpenRoads Alignment documentation for that procedure.

Note that Spirals exercise non transfer from MicroStation to MX.
