Drawing Overlays in the Windows 10 app

Not quite sure what has changed on the latest set of issued drawings? Need to check that your markups have actually been addressed in the latest version? Need to compare one floor plan with the floor below? 

To help you through each of these scenarios (and many more) Bullclip's new Overlays tool is incredibly useful. 

To get started with the Overlays tool:

  • Open a drawing you wish to overlay (eg. the latest revision).
  • Open the left hand side menu and select Overlay (third option down). 
  • The same drawing will automatically be opened in both drawing fields and the drawing content will turn purple as all the content of your first or primary drawing is shown in a solid red and all the content of your second drawing is shown in a solid blue. 
  • Select the drawing or revision you wish to compare with the primary drawing (red) in the second drawing (blue) drop down menu. 
  • Once the second drawing loads, any differences between each drawing will show up in either solid red or solid blue depending one what has changed. 
  • To minimize the menu and compare the difference in full screen, select Minimize options at the top of the menu.


  • To go one step further and see exactly what has changed and nothing else, use the Difference mode toggle at the bottom to show only what is different between the drawings. 


 To view the annotations on each drawing in the Overlay:

  • Open the Overlay options menu. 
  • Under each drawing, turn the Annotations toggle to On. 
  • The annotations on the primary (red) drawing will show up in shades of Red and the annotations in the overlaid drawing (blue) will show up in shades of Blue. 


To shift the overlaid drawing to better align with your primary drawing:

  • Open the Overlay options menu.
  • Change the Position values to shift the drawing left/right (X field) or up/down (Y field).
  • Increase or Decrease the size of the overlaid drawing using the Scale field. 
  • Rotate the overlaid drawing in 90 degree intervals by selecting the right Rotation option. 


Use a combination of the above alignment controls to get your Overlay positioned just right.
