A brief intro to the new Sheet Overlay feature in BIM Compare

Updated over a week ago

What is Sheet Overlay?

The new Sheet Overlay feature in BIM Compare enables OpenSpace users to view the Sheet drawing they used to capture in OpenSpace "overlayed," as it were, on the aligned floor of their BIM model in OpenSpace. Drawings uploaded to OpenSpace often have annotations and notes that are not available on the BIM model. If the drawing you are using to do OpenSpace captures has door tags, room tags, dimensions, or any other annotated information, you can now view that information in BIM Compare.

Additionally, OpenSpace users who are not accustomed to using BIM regularly already benefit from OpenSpace when it comes to navigating through a model using BIM Compare. Sheet Overlay can help users connect the 3D information shown in BIM Compare to the 2D drawings they look at on site every day, and get the best of both worlds.

How do I get access to Sheet Overlay?

We released this feature GA on February 6, 2023.

How do I use Sheet Overlay?

Open BIM Compare on your OpenSpace project. You project must have drawings uploaded, a BIM model uploaded and aligned, and at least one capture on at least one floor. From BIM Compare, users can click the button on the right circled in the screenshot below:

The Sheet that is aligned to that location in the BIM becomes visible in the model. Users can navigate BIM Compare as normal, and the sheet will stay visible. If the user navigates to a different floor using the Pano/Capture side, the sheet for that new floor will be visible. If the user navigates to a different floor using the BIM side, only the sheet associated with the Pano/Capture will be visible on the BIM side.

To turn off the Sheet Overlay, user simply clicks the button and the sheet will disappear.


See below to answer a couple of FAQs so far:

  • We do not yet have the capability to quickly and easily swap out which Sheet is shown in this view. We do intend to build the ability to overlay multiple Sheets here.

  • We also intend to enable customers to overlay a higher-resolution version of your Sheet, but this functionality does not yet exist today.
