Sketch Frames

Draw directly inside Refbox with lightweight sketch canvases.

Sketch Frames give you a simple drawing surface directly inside Refbox. They're useful for quick ideas, visual notes, and rough concepts without leaving your workspace.

You can create a Sketch from the Add Sketch action in the Toolbar. Refbox creates the Sketch Asset and opens it in a Frame right away.

Drawing Tools

The toolbar at the top of a Sketch Frame gives you the essentials:

Draw / Erase

Switch between drawing and erasing.

Color Picker

Choose from a built-in color palette for quick markup and sketching.

Brush Size

Pick from several brush sizes depending on whether you want broad shapes or finer lines.

Undo / Redo

Step backward or forward through recent drawing changes.

Clear

Remove all strokes from the current Sketch.

Fit to Drawing

Expand the Frame to fit your current drawing when the content grows beyond the visible area.

How Sketches Behave

Sketches save as you work, so you can treat them like lightweight working canvases inside your Box.

Unlike image, video, or PDF Frames, Sketch Frames are focused on direct editing rather than view transforms. You draw directly in the Frame instead of zooming or rotating existing content.

As you resize the Frame and keep drawing, the Sketch document can grow with it.
