The overlay appears in scene

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 can clear the PDF Overlay by clicking the object you made it with, and clicking Clear PDF (see Figure 2)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

• You are able to click through the overlay to trace your excavation below

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)
