With your overlay in scene, you can interact with it by clicking on it
Here you can use the normal Refit window to scale/move the overlay
When you Finish refitting, your overlay will become part of the scene, meaning you can click through it to the site below, making excavation more convenient
You can select it again with Visibility Override
You have a red square that is your reference frame for the intended size, if your PDF has margins you can still use the blueprint measurements and then scale and refit your overlay so the margins are outside of the red reference frame
You can also open Color Override in element properties and adjust the transparency
The overlay starts at 50% transparency
With your overlay partially transparent, you can see the ground or model below and trace out the blueprint with our new excavation tool
Once done with the overlay, you can use visibility override to hide it
You can also “Clear PDF Overlay” to start over if updates to the blueprint come in (see Figure 2)
