Draw a compass in Aquarell: connect needle and pencil legs at one hinge

A compass depends on its shared hinge and the needle and pencil tips meeting one sheet, before metallic highlights matter. Hand-draw an invented pencil-holding compass in Aquarell with a top hinge, needle leg, holder leg and short pencil. This is a structural still life, not a physical operating demonstration or a claim that the app has a mechanical compass or automatic geometric constraints.

Place the hinge and two tips first

Create an approximately 1600×1800 px portrait canvas with pale-grey paper and the whole diagonally placed compass visible. Mark the top hinge, left needle tip and right pencil tip on a sketch layer, leaving a clear opening. Join the hinge to both ends with fine paths and check for just two main legs. Remove an extra support if it resembles a tripod. Repair paper perspective and endpoints if the tips miss the same plane; shadows cannot force contact. These are composition points, not measured engineering dimensions; layers simply organise drawing.

Return both legs to the same hinge

Widen the paths into legs with small top plates overlapping around one hinge, rather than two separate knobs. A small ellipse can indicate hinge thickness, with a grip extending above. Trace left leg through hinge to right leg without a gap. If the opening reads as inverted plier jaws, establish the top convergence and separated ends before adding screws. Show visible exterior only, without invented internal gears or locking sections. A decorative dot does not become another rotation centre.

Taper the needle leg to one point

Taper the left lower leg into a short metal needle rather than ending a thick rod with a black triangle. Continue the leg axis to the chosen paper point. A pale narrow edge may separate metal from paper without making it glow. Remove wood facets and coloured casing if it resembles a second pencil; replace a foot-like pad with one clear point. Needle length is an invented proportion, not a universal specification. Do not add unexplained punctures or scratches to the paper.

Pass the pencil through its holder

Draw a small holder at the right leg end, with short pencil sections exposed above and below it. Occlusion should show the holder enclosing the shaft. Align shaft and tip before wood facets and dark graphite. Put the tip on the right endpoint without giving the holder another ground contact. Shorten extra metal below the clamp if three legs appear. Let its near edge cover a small shaft section if the pencil looks glued alongside. Choose any colour; branding cannot replace structure, and the pencil need not be transparent.

Relate the opening to a paper arc

The arc is optional. If included, hand-sketch a short curve near the pencil tip around the needle point. A circle on tilted paper has perspective; equal screen radii are not paper measurements. A short arc keeps contacts readable. Move or redraw it if it misses the tip rather than extending graphite toward it. Restart if centred on the top hinge. Any checking circle is a manual guide and establishes no automatic radius recognition by the app.

Group materials without losing the paths

Use cool-grey legs, a darker holder and warm pencil so both main paths remain distinct when reduced. Run highlights along rods rather than adding identical white circles at joints. Cast shadows toward the upper right, with tiny contacts at needle and pencil, never the elevated hinge. Soften a shadow mistaken for a third leg without deleting the real needle leg. Check the silhouette with details hidden, then restore restrained reflections. Omit engraving and screw slots when they conceal path errors.

Troubleshoot hinge, legs, holder and pencil

Temporarily colour the needle and pencil legs separately and trace hinge to tips. The holder belongs to the right leg; the pencil passes through one block. Unify a duplicated hinge, and return a floating pencil tip to its paper point before darkening shadows. If available, flipping the view may reveal skew but is no mechanical calculation. Before removing checking colours, confirm two main legs, two tips and one upper hinge. Hidden lines must not cut through a front leg. Omit uncertain model details and retain the invented-design note.

Reopen and check both contact points

Save native artwork, hide axes and temporary colour layers, export PNG and open it separately. At reduced size, identify needle and pencil tips without losing them in the arc; enlarge to inspect holder occlusion. If a third line appears, distinguish guide from shadow in the original and fix it there instead of cropping real parts. Reopen the native work to confirm editable layers and label it an invented pencil-holder compass. Success is readable connections and contacts, not measured radius, manufacturability or a new automatic circle feature.
