Understanding the Concept of Masking in MicroStation
Masking elements in MicroStation is a powerful technique used to enhance the clarity of your drawings. This function allows users to hide certain parts of elements or references while keeping other areas visible. This is especially useful when working with complex designs where certain elements may obstruct your view or distract from the primary focus.
Step-by-Step Guide to Masking an Element in MicroStation
Step 1: Define the Area to Be Masked
Begin by determining which area of the drawing you wish to mask. Using the Fence tool, create a boundary that outlines the section you want to mask. This fence can be rectangular, polygonal, or any shape that suits your needs.
Step 2: Access the Reference Dialog Box
Next, navigate to the References dialog box. This can typically be found under the “File” or “Tools” menus. Once open, you’ll see a list of all the references currently attached to your design file.
Step 3: Select the Reference Elements
In the References dialog, click to highlight the reference elements you intend to apply the mask to. Make sure you select all elements that need to be affected by the mask.
Step 4: Apply the Clip Mask
With your elements selected, locate the Mask Reference icon within the dialog. Click this icon to initiate the masking process. This action will prepare the program to use the defined fence to conceal the chosen elements.
Step 5: Finalize the Clipping Mask
To confirm your choices, make sure “Use References Dialog List” is enabled. Afterward, place a data point in your drawing. This action will lock in the mask as defined by your fence, effectively hiding the selected elements within the clipped area.
How to Mask Rasters in MicroStation
If you need to mask a raster image, the procedure differs slightly.
Step 1: Open Raster Control Toolbox
Access the Raster Control toolbox, where you will find specific tools for managing raster images.
Step 2: Select the Clip Tool
Choose the Clip tool from the toolbox. It will allow you to create a clipping mask specifically for raster elements.
Step 3: Set the Tool Parameters
In the settings panel for the Clip tool, configure the Object to “Block” and set the Mode to “Clip Mask.” If multiple raster images are open, select the one you wish to mask.
Step 4: Specify the Clipping Area
Use a data point to indicate the first corner of the clipping block. You will then be prompted to designate the opposite corner, creating a rectangular masking area.
FAQs
What is the purpose of masking in MicroStation?
Masking is utilized to hide specific elements within a design, improving the overall presentation of your drawing and helping to focus on the key components of your work without distractions from other elements.
Can I adjust the mask after it has been applied?
Yes, you can modify the mask by redefining the fence or adjusting the selected elements in the References dialog. Simply reapply the masking steps as necessary.
Is there a way to view the masked elements again?
Absolutely. You can toggle the visibility of masked elements by using the References dialog box to turn off masking or by tweaking the clipping boundaries as needed.
