How do I Annotate and Compare Drawings?

Click on the Ellipses of a Drawing sheet and select Annotate/Compare from the dropdown menu.

This will open the feature where you can annotate drawings, compare versions for changes and attach marked up plans to existing or new RFIs (Request for Information).

Overlay Comparison

The Compare feature allows users to select 2 sheets and overlay them so differences are highlighted in contrasting colors.

After selecting the first sheet:

  • Click on Compare button above to select the second sheet to overlay.
  • If there are earlier versions/revisions of the sheet, those will appear automatically. Select from those or clear out the search cell above to see all sheets to select from drawings. You can also use type-ahead in this cell to search for a particular sheet.

Differences in the compared drawings will appear marked in the corresponding blue or red colors.

You can toggle between Document A and Document B tabs to confirm changes, which may be required on sheets that already use color. 

Please Note: Color comparison will only appear on files split using the Upload, Split and Scan after January 6th, 2023. Files that were split previously will only show the comparison overlay in grayscale.

Align

If the sheets selected do not line up exactly, the Align option can be used. It will require you to select 3 reference points to align on the drawings. The Align feature will appear differently depending upon the device used. The desktop Align tool appears with the zoom tool that can be used to click on the exact points. Click Reset as needed if you need additional repositioning.
Tablets, touchscreen computers, and handheld devices will have a touchpoint tool to select. You will first need to zoom into the sheet ensure you have sliding toolbars on both axes, then use your finger to move the actual drawing sheet itself to align the pointer then click select point to mark each location.

Redline Markups

Redline Markups are the new Annotation area. The dynamic save will be retained as Private save in drawings until they are Published. When on Private save, the markups will are only be visible to GC users.

Annotation Log

Click on Thumbnails dropdown icon to left and select Annotations to see list of markups that have been changes on left hand side view.

Published Annotations will now appear on the OCR interactive view.  Some Items are unavailable in this view (like text notes).

Markup and Attach – RFIs

Markup and attach will allow users to markup a drawing sheet and add it to an existing RFI or to create a new RFI. It will open the RFI worksheet with the annotated drawing sheet attached, which can be updated and submitted for answers.

The Annotations that are attached to the RFI will not appear on the Public view of the drawing. If you wish the markups to be public you will need to use redline markup, publish and then proceed to Markup and Attach to the desired RFI.
