How to Change Scale in MicroStation?

Understanding Scale in MicroStation

MicroStation is a powerful CAD application widely used for design and drafting. One crucial aspect of working with MicroStation involves understanding how to effectively manage and modify scales. This article breaks down how to change scale in MicroStation, offers insights into various scale features, and provides clear steps for achieving your design goals.

Steps to Change Scale in MicroStation v8i

Changing scale within MicroStation v8i can enhance the accuracy of your drawings. Here’s how you can do it:

Accessing the Scale Settings

  1. Open the Models Dialog: Begin by navigating to the ‘File’ menu and select ‘Models’ to launch the Models dialog. This window provides access to all models within your file.

  2. Model Properties: Right-click on the model whose scale you want to modify and select ‘Properties’. This option opens the Model Properties dialog, where various settings can be adjusted.

  3. Adjust Line Style Scale: Look for the ‘Line Style Scale’ option. Here, you can set the scale to apply globally across all line styles in the model.

  4. Confirm the New Scale: After inputting the desired scale value for the line styles, click ‘OK’ to save the changes.

Utilizing the Scale Tool

To accurately scale objects or drawings in MicroStation, follow these steps:

  1. Select the Scale Tool: Access the Scale tool through the toolbox or by navigating to ‘Home’ > ‘Transform’ > ‘Scale’.

  2. Choose the Objects: Click on the elements you wish to scale. You can either click and drag a selection window around multiple elements or select them individually.

  3. Specify Base Point: Identify a base point from where the scaling will initiate. This point is crucial as it will remain fixed while other elements adjust around it.

  4. Enter Scale Factor: Use the command window or dialog to input the scaling factor. For instance, entering 2 will double the size of the selected objects, while entering 0.5 will reduce their size by half.

  5. Apply the Scaling: Once you’ve configured the settings, confirm your choice. The elements will adjust in size according to the specified scale factor.

Scaling Raster Images

If your work involves raster images, MicroStation offers tools for effectively scaling these images as follows:

  1. Open Raster Manager: Navigate to ‘File’ and select ‘Raster Manager’ to view all attached raster files.

  2. Select Raster: Choose the raster image you want to resize from the list.

  3. Scale Option: Click on the Scale icon from the toolbar.

  4. Tool Settings: In the settings dialog, select ‘Active Scale’ to modify dimensions.

  5. Aspect Ratio Lock: Ensure that you toggle the lock icon according to your needs. If you want to maintain the image’s proportionality, keep the lock icon activated.

  6. Finalize the Changes: Once all settings are correct, confirm the changes, and the raster will be rescaled as specified.

Modifying Dimension Sizes

For texts and dimensions, changing sizes and scale can be done as follows:

  1. Open the Text Toolbar: Use the pulldown menu to access ‘Tools’ > ‘Main’ > ‘Text’ to open the Text toolbar.

  2. Select Edit Text Tool: Use the Edit Text tool to choose dimension text that you want to modify.

  3. Enter New Dimensions: With the edit tool active, either adjust the existing dimension size or add new values as needed.

  4. Save Adjustments: Make sure to apply the changes to ensure your dimensions reflect accurately within the drawing.

Frequently Asked Questions

How can I quickly match line properties in MicroStation?
To match line properties, utilize the Change Attribute tool. Click the eyedropper icon (Match Element Attributes), select your source element, check the properties you want to match, and then click on the element to which you want to apply those properties.

What should I do if my raster image appears distorted after scaling?
Ensure that you are appropriately locking the aspect ratio when scaling. If the lock is disabled, the image may stretch disproportionately. If you’re still having issues, check the original image dimensions before scaling them back to their appropriate size.

Is there a way to reverse a line’s direction in MicroStation?
Yes, select the Change Element Direction tool, set it to ‘Change Direction’, click on the element whose direction you want to reverse, and confirm your selection. The arrow visual will indicate that the direction has been successfully reversed.
