Understanding PDF Underlays in AutoCAD
PDF underlays are external references that you can incorporate into your AutoCAD drawings. They provide a way to link a PDF file to your project, enabling you to utilize the visual information without directly modifying the original content. This process is useful for maintaining accuracy when working with designs or architectural plans.
Steps to Crop a PDF Underlay in AutoCAD
-
Deselect Any Selected Objects
Start by clicking on an empty area within your drawing. This will ensure that no other elements are currently selected, allowing for a clearer workflow. -
Activate the Crop Tool
Position your cursor around the edges of the PDF underlay. Once your cursor changes to the crop icon, right-click to bring up a context menu. From here, select the "Crop Tool" option. -
Adjust the Crop Area
You will see crop handles appear around your PDF underlay. Click and drag these handles to define the new boundaries of the underlay. Ensure that the cropped area accurately reflects the portion of the PDF you want to keep. - Finalize the Crop
After adjusting the crop area to your satisfaction, press Enter to apply the changes. The underlay will now display only the cropped section.
