Understanding Arc Creation in MicroStation
Drawing arcs in MicroStation requires the use of specific tools and techniques that are straightforward once mastered. This guide walks you through the essential steps for constructing and editing arcs effectively.
Steps to Construct an Arc
Select Your Tool: Begin by choosing either the Arc tool or the Pie tool from the toolbox. The Arc tool allows for drawing arcs freely, while the Pie tool creates pie slices.
Define the Center: Click on the canvas where you want the center of the arc to be located. This step is crucial as it establishes the pivot point around which the arc will be drawn.
Set the Starting Point: Move your cursor to the desired starting point of the arc. Once you’re satisfied with the placement, click to set this point.
Determine the Ending Point: Continue moving your cursor to where you want the arc to end. This step sets the span of the arc. Click to finalize the endpoint.
- Finalizing the Drawing: Check the arc’s appearance on the screen. You should see a smooth, curved line connecting the start and end points, radiating from the center.
Measuring Arc Length in MicroStation
To accurately measure the length of an arc in MicroStation:
Select the Arc: Highlight the arc that you want to measure by clicking on it.
Open the Dimension Toolbox: Navigate to the Dimension toolbox found in the main toolbar.
- Choose Arc Size: Click on the “Arc Size” option from the Dimension Angular tool. This will display the arc length in the attribute window.
Editing an Existing Arc
Modifications may be necessary for refining arcs. Follow these steps to adjust an arc:
Identify the Arc: Use the “Identify” function to select the arc you wish to edit. Click near the arc’s end for easier selection.
Prompt for Edits: Upon selection, a prompt will guide you on how to modify the arc angle. You can adjust the arc sweep or change its radius.
- Accept or Reject Changes: Confirm your modifications by clicking the Data button to accept the changes, or press the Reject button if you’re not satisfied with the adjustments.
Additional Features Associated with Arcs
Tangential Arcs: These are arcs that connect smoothly with a circular arc or line, maintaining a continuous curve.
- Arc Commands: Besides the basic creation steps, you can also define arcs by specifying parameters like radius, chord length, and direction. This allows for more complex and precise arc designs.
Frequently Asked Questions
1. What tools can I use to create more complex arcs in MicroStation?
Advanced arcs can often be drawn using the Arc command, where you can input parameters like radius and angle for greater precision.
2. Can I adjust an arc after I have drawn it?
Yes, you can edit arcs using the Modify tools, allowing you to change the angle, length, and direction of the arc as needed.
3. How can I measure the area covered by an arc?
To measure an area that includes arcs, use the Measure Area tool in the Analyze tab to select the surrounding elements, which will provide you with the area and perimeter details.
