Issue:

When a PDF drawing is inserted via Insert → PDF Underlay, internal lines cannot be snapped to. How can this be configured?

Solution:

  • Method 1: Select the inserted PDF image, right-click, and select PDF Object Snap from the context menu.

  • Method 2: Alternatively, enter the command PDFOSNAP in the command line and set the value to 1.
