Understanding Layer Purging in MicroStation
When working with MicroStation, it’s important to manage the layers efficiently to maintain a clean and organized workspace. Purging layers that are no longer in use can help optimize file size and performance. This guide will walk you through the steps necessary to purge layers in MicroStation.
Step-by-Step Instructions for Purging Layers
Step 1: Access the Compress Options
The first step in purging layers is to access the file options where compression settings are located. Start by navigating to the top menu bar of MicroStation.
- Click on File in the menu.
- From the dropdown menu, select Compress.
- Then, choose Options to open the Compress Options dialog box.
Step 2: Enable the Selection for Unused Layers
Once you are in the Compress Options dialog box, you will need to specify which features you want to clean up.
- Look for the checkbox labeled Delete Unused Levels in the dialog box.
- Make sure to place a checkmark next to this option to enable it. This ensures that any levels (layers) that do not contain any elements will be purged.
Step 3: Optional Considerations
If you are working with external references that might also have unused levels, you can include them in the purge process.
- Locate the option on the same dialog labeled Include References.
- If applicable, put a checkmark next to this option as well. This step will ensure that unused levels in referenced files are included in the purging process.
Step 4: Execute the Compression
After setting your preferences in the Compress Options dialog, it’s time to execute the purge.
- Click the Compress button located at the bottom of the dialog box.
- This action will initiate the process of purging the unused layers based on your settings, effectively removing them from your file.
Step 5: Verify the Result
After the compression is completed, it is wise to verify that the unused layers have been successfully purged.
- Reopen the Levels dialog by navigating to Settings > Levels > Display.
- Check the list of layers to ensure that the previously unused layers are no longer visible.
FAQ
1. What happens to the elements on the purged layers?
When you purge layers that contain elements, those elements are removed along with the layer. It’s crucial to ensure that any important elements are moved to another layer before purging.
2. Can I restore purged layers later?
Once you purge layers in MicroStation, they are permanently removed, and there is no direct way to restore them. It’s recommended to create backups of your files before performing a purge.
3. Is there a way to preview which layers will be deleted before purging?
MicroStation does not have a built-in preview feature for unused layers. However, you can manually check the layers by looking at the elements contained within them in the Level Display dialog before proceeding with the purge.
