Viewing, comparing, and marking up drawings

Adding and editing drawing markup

Use drawing markup to call attention to a location, add notes, sketch an idea, or prepare a formal Topic.

Use drawing markup to call attention to a location, add notes, sketch an idea, or prepare a formal Topic.

Best for: Anyone coordinating from a plan · Requires: The permission for the record or Topic that will own the markup.

Choose a markup tool

The viewer includes:

  • Pencil
  • Highlighter
  • Text
  • Lines and arrows
  • Clouds
  • Rectangles, circles, and ellipses
  • Cross symbols

Choose a color and line thickness before drawing, or select existing markup to update it.

Select and edit markup

Use the Select tool to choose one or more shapes. Depending on the selection, you can:

  • Move or resize it
  • Copy, cut, and paste
  • Copy or move it to another Topic
  • Delete it

Standard clipboard shortcuts work on desktop. You can also use the viewer's context menu.

Use Undo and Redo if an edit does not go as planned. Undo history belongs to the current editing session, so don't rely on it after leaving the viewer.

On a phone, the active tool, color, and line thickness are grouped into the bottom toolbar. The full tool list opens in a drawer, and Done returns you to Pan without deleting the markup you just created.

Finish measurements and multi-point shapes

Some tools remain active while you add points. Select End or Done when the shape is complete, or switch back to Pan.

If the viewer seems to keep drawing when you try to navigate, check the active tool and return to Pan or Select.

Hide vs. delete

Hide Markup temporarily gives you a clean drawing view. Delete removes selected markup from its Topic or draft.

When deleting a pin, Constructable may ask for confirmation because the pin can be connected to comments or another project record.

Save work in context

New markup may begin in Draft Mode. Save it to a Topic before leaving if you want to keep it. Continue with Saving and collaborating with Topics.
