3D Overlays – Revizto

3D overlays allow you to view a 2D sheet over a section cut of a 3D model. 3D overlays allow you to quickly compare your sheets and your models for verification.

Accessing 3D overlays

You can access 3D overlays from the 2D gallery, or from a sheet that has the Jump to 3D button located on the 2D toolbar.

To access 3D overlays from the 2D gallery:

Click 2D and navigate to a sheet with a 3D overlay.
- You can use the Overlays filter to quickly show relevant sheets.
Click the Overlay icon to open the 3D model with the sheet overlay.
- Sheets with the Multiple overlays icon will open the sheet first for overlay selection.

To access 3D overlays from a sheet:

In an open sheet, click the Jump to 3D button from the 2D toolbar. If you have multiple overlays, you will be prompted to select which overlay to open.
Alternatively, click the Sheet overlay shortcut on the sheet to directly open the overlay.

Adding 3D overlays

Once you have sheets and models imported into Revizto you can add 3D overlays to your sheets. Overlays transfer with new sheet versions and will automatically use the updated sheets as the overlay.

Existing overlays cannot be edited.

To change existing overlays, first Delete existing viewports then create new overlays.

To add a new 3D overlay:

Click 2D and select your sheet. This is the sheet that will overlay the 3D model.
Click the Set up 3D overlay button on the right side of the toolbar.
Select the area for the 3D overlay, then click Done. You can adjust the viewport by clicking and dragging the selection box. Everything within the green box will be displayed in the overlay.
- New viewports cannot overlap with existing viewports. Adjust the area until all viewports are shown in green or click Delete existing viewports. Deleting existing viewports will remove all overlays from the sheet.
Cut a section plane for the sheet overlay, then click Done. You can move the plane by clicking and dragging the section cut tool.

Revizto automatically aligns the section cut to the model based on the 2D sheet coordinates. You can manually align the section cut to different surfaces by clicking and dragging the bottom of the section cut tool.
Position the sheet to match the 3D model, then click Done. You can move the sheet position by clicking and dragging the yellow pivot points. You can also adjust the section plane position, which is displayed when opening the 3D overlay.
- Pivot points can be moved on the sheet by holding the Ctrl key and dragging the point to a new position.
  Best practice is moving the pivot points to opposite corners of the drawing and then positioning the overlay.
Set the issue capturing boundaries, then click Done.
- The issue capture boundary determines what issues are shown on the 2D sheet when overlaying a model. Issues outside of the boundary will be hidden.
