# LabCanvas tutorials > Step-by-step LabCanvas tutorials: journal-size figures, DNA brushes, zoom lens callouts, presentations, ray-traced 3D, freehand 3D drawing, protein residues… URL: https://www.labcanvas.com/tutorials Short, step-by-step guides for the things scientists do most: journal figures, DNA and protein visuals, zoom callouts, talks, 3D renders and statistics. Figure editor ### Make a journal figure at the right size - Open the dashboard and start a new figure. - Build panels with shapes, objects (Shift+O), equations and images; group each panel. - Add panel letters with the Text tool (T) and align them with Arrange. - Download: choose TIFF or PDF, the journal column width (for example 85 or 174 mm) and 300–600 dpi. [Open Figure editor](https://www.labcanvas.com/editor.html) Figure editor ### Draw DNA along a path - Pick the Brush tool (B) and choose DNA double helix. - Draw the path; it is smoothed into Bézier curves. - In the Line settings set the form (B, A or Z), base-pair style, colours and an optional sequence. - Use Expand to turn the brush into ordinary paths if you need to edit pieces. [Open Figure editor](https://www.labcanvas.com/editor.html) Figure editor ### Add a zoom lens callout - Click Lens in the left toolbar: a magnifier appears with a ring on the area it enlarges. - Drag the lens where you want it; the ring stays on the source. - Double-click the lens and drag its small ring to magnify another spot. - In the Design panel set the zoom, round or square shape, frame style and callout lines. [Open Figure editor](https://www.labcanvas.com/editor.html) Slides ### Present a talk with Slides - Open Slides from the dashboard or the editor’s top bar. - Add slides with Ctrl+M and pick a layout; paste figures from the editor with Ctrl+V. - Set transitions and speaker notes in the slide panel. - Press F5 to present, or export the deck as one vector PDF.
